    Stress fractures are repetitive strain injuries that occur in normal bones and in abnormal bones. Stress fractures share many features in common but differences depend on the status of the underlying bone. This review article for clinicians addresses aspects about stress fractures with particular respect to fatigue fractures, Looser zones of osteomalacia, atypical Looser zones, atypical femoral fractures associated with bisphosphonate therapy and stress fractures in Paget's disease of bone.

    At the present time proximal femoral fractures account for 30% of all fractures referred to hospitals for treatment. Our population is ageing, the proportion of patients with post-menopausal or senile osteoporosis is increasing and therefore the number of proximal femoral fractures requiring urgent treatment is growing too. In the age category of 50 years and older, the incidence of these fractures has increased exponentially. Our department serves as a trauma centre for half of Prague and part of the Central Bohemia Region with a population of 1 150 000. Prague in particular has a high number of elderly citizens. Our experience is based on extensive clinical data obtained from the Register of Proximal Femoral Fractures established in 1997. During 14 years, 4280 patients, 3112 women and 1168 men, were admitted to our department for treatment of proximal femoral fractures. All patients were followed up until healing or development of complications. In the group under study, 82% were patients older than 70 years; 72% of those requiring surgery were in their seventies and eighties. Men were significantly younger than women (p<0.001) and represented 30% of the group. The fractures were 2.3-times more frequent in women than in men. In the category under 60 years, men significantly outnumbered women (p<0.001). The patients with pertrochanteric fractures were, on the average, eight years older than the patients with intertrochanteric fractures, which is a significant difference (p<0.001). The mortality rate within a year of injury was about 30%. Trochanteric fractures accounted for 54.7% and femoral neck fractures for 45.3% of all fractures. The inter-annual increase was 5.9%, with more trochanteric than femoral neck fractures. There was a non-significant decrease in intertrochanteric (AO 31-A3) fractures. On the other hand, the number of pertrochanteric (AO 31-A1+2) fractures increased significantly (p<0.001). A total of 1 394 fractures were treated with a proximal

    We demonstrated microdamage accumulation in the fracture sites in the patients of subtrochanteric atypical femoral fracture with long term bisphosphonate therapy and of incomplete shaft fracture of lateral femoral bowing without bisphosphonate therapy. Based on these findings, pathogenesis of atypical femoral fracture is revealed stress fracture caused by accumulation of microdamages between distal to the lesser trochanter and proximal to the supracondylar flare in the femur in association with severely suppressed bone turnover and/or abnormal lower limb alignment, that causes stress concentration on the lateral side cortex of the femur.

    Stress fractures are common injuries in sports medicine. Among these fractures, femoral neck stress fractures frequently have a benign course, especially when it happens in the medial aspect of the neck. This case report describes a stress fracture of the medial aspect of the femoral neck that developed a complete fracture and underwent surgical fixation. PMID:23283621

    The diversity of surgical options for the management of distal femoral fractures reflects the challenges inherent in these injuries. These fractures are frequently comminuted and intra-articular, and they often involve osteoporotic bone, which makes it difficult to reduce and hold them while maintaining joint function and overall limb alignment. Surgery has become the standard of care for displaced fractures and for patients who must obtain rapid return of knee function. The goal of surgical management is to promote early knee motion while restoring the articular surface, maintaining limb length and alignment, and preserving the soft-tissue envelope with a durable fixation that allows functional recovery during bone healing. A variety of surgical exposures, techniques, and implants has been developed to meet these objectives, including intramedullary nailing, screw fixation, and periarticular locked plating, possibly augmented with bone fillers. Recognition of the indications and applications of the principles of modern implants and techniques is fundamental in achieving optimal outcomes. PMID:20889949

    Intra-capsular femoral neck fractures are seen commonly in elderly people following a low energy trauma. Femoral neck fracture has a devastating effect on the blood supply of the femoral head, which is directly proportional to the severity of trauma and displacement of the fracture. Various authors have described a wide array of options for treatment of neglected/nonunion (NU) femoral neck fracture. There is lack of consensus in general, regarding the best option. This Instructional course article is an analysis of available treatment options used for neglected femoral neck fracture in the literature and attempt to suggest treatment guides for neglected femoral neck fracture. We conducted the “Pubmed” search with the keywords “NU femoral neck fracture and/or neglected femoral neck fracture, muscle-pedicle bone graft in femoral neck fracture, fibular graft in femoral neck fracture and valgus osteotomy in femoral neck fracture.” A total of 203 print articles were obtained as the search result. Thirty three articles were included in the analysis and were categorized into four subgroups based on treatment options. (a) treated by muscle-pedicle bone grafting (MPBG), (b) closed/open reduction internal fixation and fibular grafting (c) open reduction and internal fixation with valgus osteotomy, (d) miscellaneous procedures. The data was pooled from all groups for mean neglect, the type of study (prospective or retrospective), classification used, procedure performed, mean followup available, outcome, complications, and reoperation if any. The outcome of neglected femoral neck fracture depends on the duration of neglect, as the changes occurring in the fracture area and fracture fragments decides the need and type of biological stimulus required for fracture union. In stage I and stage II (Sandhu's staging) neglected femoral neck fracture osteosynthesis with open reduction and bone grafting with MPBG or Valgus Osteotomy achieves fracture union in almost 90% cases

  7. History of femoral head fracture and coronal fracture of the femoral condyles.

    The first known description of the coronal fracture of the lateral femoral condyle was published by Busch in 1869. Hoffa used Busch's drawing in the first edition of his book in 1888 and accompanied it only with one sentence. A full case history of this fracture pattern was described by Braun in 1891. However, Braun's article fell into oblivion and so the fracture was popularized only in the fourth edition of Hoffa's textbook, particularly thanks to the drawing, rather than the brief description. Therefore, a fracture of the posterior femoral condyle, or more specifically, of the lateral condyle, could properly be called "Busch-Hoffa fracture". Femoral head fracture was initially described by Birkett in 1869. Of essential importance in this respect were the publications by Christopher in 1924 and, particularly, Pipkin's study of 1957, including his classification that is still in use today. A historically correct eponym for a femoral head fracture would therefore be "Birkitt-Pipkin fracture". PMID:25787681

    Objective: To evaluate the personal, fracture, treatment and complication characteristics among patients with pediatric femoral shaft fractures attended at the pediatric orthopedic service of the Joana de Gusmão Children's Hospital. Methods: This was a retrospective cross-sectional study on a population consisting of patients with femoral shaft fractures, aged between birth and 14 years and 11 months, who were divided into four age groups. Information was obtained from medical records and was transferred to a survey questionnaire to present personal, fracture, treatment and complication variables. Results: The study population consisted of 96 patients. Their mean age was 6.8 years. The cases were predominantly among males, comprising closed fractures on the right side, in the middle third with a single line. Regarding fracture etiology, traffic accidents predominated overall in the sample. Most of the patients (74 to 77.1%) presented femoral fractures as their only injury. Conservative treatment predominated in the group younger than six years of age, and surgical treatment in the group aged 6 to 14 years and 11 months. The complications observed until bone union were: discrepancy, infection and movement limitation. The mean time taken for consolidation was 9.6 ± 2.4 weeks, varying with age. Conclusion: The features of these fractures were similar to those described in the literature and the treatment used showed good results. The Joana de Gusmão Children's Hospital has used the treatment proposed in the literature for pediatric femoral shaft fractures. PMID:27042619

    Intramedullary nail fixation of pediatric long bone fracture, particularly femoral shaft fracture, has revolutionized the care and outcome of these complex injuries. Nailing is associated with a high rate of union and a low rate of complications. Improved understanding of proximal femoral vascularity has led to changes in nail insertion methodology. Multiple fixation devices are available; selection is based on fracture type, patient age, skeletal maturity, and body mass index. A thorough knowledge of anatomy and biomechanics is required to achieve optimal results without negatively affecting skeletal development. PMID:21807915

    Optimizing stability of femoral neck fracture fixation is important in obtaining a successful outcome. The mechanical problems and strategies for achieving optimal stability differ depending on patients' age and degree of osteoporosis. Femoral neck fractures in younger adults usually result from high-energy trauma and have a vertical fracture pattern. Strategies for optimizing fixation stability in this group include placing additional screws at right angles to the fracture plane and medial buttress plate augmentation. In elderly patients, screw position relative to the intact cortical femoral neck bone is of critical importance. Additional strategies for optimizing fixation stability in this group include the concept of length stable fixation, use of adjunctive calcium phosphate cement, and use of novel fixed angle fixation implants.

    The diagnosis of spontaneous stress fractures of the femoral neck, a form of insufficiency stress fracture, can be missed easily. Patients present with unremitting hip pain without a history of significant trauma or unusual increase in daily activity. The initial radiographic features include osteoporosis, minor alterations of trabecular alignment, minimal extracortical or endosteal reaction, and lucent fracture lines. Initial scintigraphic examinations performed in three of four patients showed focal increased radionuclide uptake in two and no focal abnormality in one. Emphasis is placed on the paucity of early findings. Evaluation of patients with persistent hip pain requires a high degree of clinical suspicion and close follow-up; the sequelae of undetected spontaneous fractures are subcapital fracture with displacement, angular deformity, and a vascular necrosis of the femoral head.

    Secondary fractures around femoral nails placed for the management of hip fractures are well known. We report, two cases of a fracture of the femur at the interlocking screw site in the subtrochanteric area after retrograde femoral nailing of a femoral shaft fracture. Only a few reports in the existing literature have described these fractures. Two young men after sustaining a fall presented to us with pain, swelling and deformity in the upper thigh region. On enquiring, examining and radiographing them, peri-implant fractures of subtrochanteric nature through the distal interlocking screws were revealed in both patients who also had histories of previous falls for which retrograde intramedullary nailing was performed for their respective femora. Both patients were managed with similar surgical routines including removal of the existing hardware, open reduction and ace cephallomedullary antegrade nailing. The second case did show evidence of delayed healing and was additionally stabilized with cerclage wires. Both patients had uneventful postoperative outcomes and union was evident at the end of 6 mo postoperatively with a good range of motion at the hip and knee. Our report suggests that though seldom reported, peri-implant fractures around the subtrochanteric region can occur and pose a challenge to the treating orthopaedic surgeon. We suggest these be managed, after initial stabilization and resuscitation, by implant removal, open reduction and interlocking intramedullary antegrade nailing. Good results and progression to union can be expected in these patients by adhering to basic principles of osteosynthesis. PMID:26495251

    Introduction: Periprosthetic fractures of the femur are uncommon, but at times may lead to complications especially in elderly patients. As treatment of these fractures is difficult, prevention by identifying the risk factors is the best way to overcome these complex problems. Case Report: A periprosthetic right femur fracture associated with a neglected left femoral neck fracture in the contralateral femur in a 78-year-old elder woman patient is reported in the present article. We discuss the prevention of periprosthetic fractures after hip arthroplasty and address the risk factors associated with this complication. Conclusion: The present case emphasizes the importance of investigating and treating the cause of sudden onset of restriction on full weight-bearing in the contralateral limb, to prevent periprosthetic femoral fracture after hip arthroplasty in elderly patients.

    Femoral midshaft fracture is one of the most common clinical injuries and is often caused by high-energy traffic accidents. Intramedullary nailings, plates, and external fixators are all used as treatment alternatives for a variety of patients depending on fracture location, displacement, comminution, soft tissue condition, and local tradition. Locked intramedullary nailing is currently the preferred treatment method for most diaphyseal fractures and has good clinical results. The goal of this study was to compare expandable and locked intramedullary nailing for the treatment of AO type 32A and 32B1 femoral midshaft fractures. The authors performed a retrospective analysis of 46 patients (33 men and 13 women; mean age, 32.3 years; range, 22-52 years) with femoral midshaft fractures who were divided into 2 groups-one treated with an expandable intramedullary nailing method and the other with a conventional locked intramedullary nailing. The 2 groups were compared with respect to operation time, fluoroscopic time, amount of estimated blood loss, hospitalization time, healing time, and complications. Patients were followed for at least 1 year. The results of this study showed that all of the patients achieved bone union within 12 to 24 months. Expandable nailing performed better than locked nailing in operation time, fluoroscopic time, amount of estimated blood loss, and healing time (P<.001). There was no difference in hospitalization time and no visible shortening or severe complications were observed in either group. Based on the results of this study, the expandable intramedullary nailing is an easy and effective treatment for AO type 32A and 32B1 diaphyseal femoral fractures. PMID:25901625

    A 68-year-old female patient admitted to our clinic with right anterior thigh pain ongoing for six months and which increased in last two months. The patient had no trauma history. The patient had been followed-up for 15 years because of osteoporosis and administrated alendronate and ibandronate treatment for 10 years. Patient had three shots of zoledronate once a year during the last three years. Her pain was increasing when she was walking. Physical examination revealed pain in her right thigh. Radiogram showed thickened lateral cortex of the subtrochanteric area. Magnetic resonance imaging also showed thickening and edema of the same area. These images were correlated with atypical fracture in right femoral subthrochanteric zone. Dual energy X-ray absorptiometry revealed that T score was -3.3 in lumbar region and -2.5 in femoral neck. Zoledronate treatment was ended. Prophylactic surgical fixation was performed with titanium elastic nails. PMID:26874637

    Atypical femoral fractures are stress or insufficient fractures induced by low energy trauma or no trauma and have specific X-ray findings. Although the American Society for Bone and Mineral Research has excluded periprosthetic fractures from the definition of an atypical femoral fracture in 2013, this is still a matter of controversy because some authors report periprosthetic fractures showing specific features of atypical fractures around a well-fixed femoral stem. We report 3 cases of periprosthetic femur fractures that had specific radiographic features of atypical femoral fractures in patients with a history of prolonged bisphosphonate use; we also review relevant literature.

    Background Subcapital femoral neck is known to cause many complications, such as avascular necrosis (AVN) of the femoral head or nonunion, compared with other femoral neck fractures. The purpose of this study was to analyze the incidence of AVN and fixation failures in patients treated with internal fixation using cannulated screws for the subcapital femoral neck fractures. Methods This study targeted a total of 84 cases of subcapital femoral neck fractures that underwent internal fixation using cannulated screws. The average follow-up time after surgery was 36.8 months (range, 24 to 148 months). Results Nine hips (10.7%) showing AVN of the femoral head and 6 hips (7.1%) showing fixation failures were observed. The factors affecting the incidence of AVN of the femoral head after sustaining fractures correlated well with fracture types in the Garden classification (p = 0.030). The factors affecting fixation failure were the degree of reduction (p = 0.001) measured by the Garden alignment index and firm fixation (p = 0.009) assessed using the technique of 3-point fixation through the inferomedial cortical bone of the femoral neck. Conclusions The complication rates for subcapital femoral neck fractures were lower than those previously reported; hence, internal fixation could be a primary treatment option for these fractures.

    Displaced femoral neck fractures are rare in children and are associated with a high rate of complications. Subtrochanteric fractures after cannulated screw fixation of femoral neck fractures in adults are well recognized, and there are several reports on the topic. However, there are no reports on complications related to hardware or subtrochanteric fractures after removal of the screws in the treatment of femoral neck fractures in children.

    This article describes the case of a 69-year-old patient with an occult acetabular fracture complicated by an ipsilateral femoral neck fracture occurring within 2 months. The acetabular fracture remained undiagnosed at examination due to insufficient clinical and radiographic data interpretation. The patient was assured of early mobilization that led to a fall and subsequent hip fracture. We focus on the potential reasons for the nondiagnosis of the acetabular fracture. Acetabular fractures in the elderly may occur after low-energy injuries. The lack of history of violent injury may lead to an incorrect diagnosis. Plain anteroposterior (AP) pelvis radiographs alone may prove an insufficient tool, especially in the hands of inexperienced personnel. As is characteristic, a retrospective review of the AP pelvis radiograph obtained after the first fall in our case revealed the undisplaced fracture of the anterior column that was missed initially. Combined fractures of the hip and the acetabulum are rarely described in the literature and are usually addressed by total hip arthroplasty (THA) alone. Similar fracture patterns that develop in 2 stages (2 injuries), as the 1 presented herein, are even more rare. The uniqueness of this combined fracture required a unique surgical treatment. The senior surgeon (P.V.G.) addressed the acetabular fracture separately to graft the anterior column fracture and facilitate union, as it was already 8 weeks old and the second fall had generated a further gap between the fragments. Stable fixation was felt appropriate prior to the THA. Thus, a double surgical approach was used. Six weeks postoperatively, the patient was able to perform full weight-bearing mobilization without an antalgic gait pattern. At 6-month follow-up, radiographs showed the metalwork to be in place with no displacement, and the fracture had progressed to union. PMID:19708620

    Background Proximal femoral geometry may be a risk factor of osteoporotic hip fractures. However, there existed great differences among studies depending on race, sex and age of subjects. The purpose of the present study is to analyze proximal femoral geometry and bone mineral density (BMD) in the osteoporotic hip fracture patients. Furthermore, we investigated proximal femoral geometric parameters affecting fractures, and whether the geometric parameters could be an independent risk factor of fractures regardless of BMD. Methods This study was conducted on 197 women aged 65 years or more who were hospitalized with osteoporotic hip fracture (femur neck fractures ; 84, intertrochanteric fractures; 113). Control group included 551 women who visited to check osteoporosis. Femur BMD and proximal femoral geometry for all subjects were measured using dual energy X-ray absorptiometry (DXA), and compared between the control and fracture groups. Besides, proximal femoral geometric parameters associated with fractures were statistically analyzed. Results There were statistically significant differences in the age and weight, cross-sectional area (CSA)/length/width of the femoral neck and BMD of the proximal femur between fracture group and control group. BMD of the proximal femur in the control group was higher than in the fracture group. For the femoral neck fractures group, the odds ratio (OR) for fractures decrease in the CSA and neck length (NL) of the femur increased by 1.97 times and 1.73 times respectively, regardless of BMD. The OR for fractures increase in the femoral neck width increased by 1.53 times. In the intertrochanteric fracture group, the OR for fractures increase in the femoral neck width increased by 1.45 times regardless of BMD. Conclusions We found that an increase of the femoral neck width could be a proximal femoral geometric parameter which plays important roles as a risk factor for fracture independently of BMD.

    Background: When primary fixation of proximal femoral fractures with implants fails, revision osteosynthesis may be challenging. Tracts of previous implants and remaining insufficient bone stock in the proximal femur pose unique problems for the treatment. Intramedullary implants like proximal femoral nail (PFN) or surface implants like Dynamic Condylar Screw (DCS) are few of the described implants for revision surgery. There is no evidence in the literature to choose one implant over the other. We used the reverse distal femur locking compression plate (LCP) of the contralateral side in such cases undergoing revision surgery. This implant has multiple options of fixation in proximal femur and its curvature along the length matches the anterior bow of the femur. We aimed to evaluate the efficacy of this implant in salvage situations. Materials and Methods: Twenty patients of failed primary proximal femoral fractures who underwent revision surgery with reverse distal femoral locking plate from February 2009 to November 2012 were included in this retrospective study. There were 18 subtrochanteric fractures and two ipsilateral femoral neck and shaft fractures, which exhibited delayed union or nonunion. The study included 14 males and six females. The mean patient age was 43.6 years (range 22–65 years) and mean followup period was 52.1 months (range 27–72 months). Delayed union was considered when clinical and radiological signs of union failed to progress at the end of four months from initial surgery. Results: All fractures exhibited union without any complications. Union was assessed clinically and radiologically. One case of ipsilateral femoral neck and shaft fracture required bone grafting at the second stage for delayed union of the femoral shaft fracture. Conclusions: Reverse distal femoral LCP of the contralateral side can be used as a salvage option for failed fixation of proximal femoral fractures exhibiting nonunion. PMID:27512218

    Bone disease, specifically low bone mineral density, is a common and undertreated complication that begins during childhood in patients with cystic fibrosis (CF). This case describes a male baseball player, aged 14years, with undiagnosed CF who sustained a left midshaft femoral fracture while running toward base; 8months later, he sustained a right midshaft femoral fracture under similar conditions. After the second fracture, further evaluation revealed low bone mineral density and CF. There is no previously published report of pathologic fractures occurring in the femoral shaft in an athlete with undiagnosed CF. Patients with CF have a higher fracture rate. Low-energy fractures of major bones in athletically active individuals should be viewed with suspicion for an underlying process. PMID:26927602

    This study assesses femoral neck shortening and its effect on gait pattern and muscle strength in patients with femoral neck fractures treated with internal fixation. Seventy-six patients from a multicenter randomized controlled trial participated. Patient characteristics and Short Form 12 and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores were collected. Femoral neck shortening, gait parameters, and maximum isometric forces of the hip muscles were measured and differences between the fractured and contralateral leg were calculated. Variables of patients with little or no shortening, moderate shortening, and severe shortening were compared using univariate and multivariate analyses. Median femoral neck shortening was 1.1 cm. Subtle changes in gait pattern, reduced gait velocity, and reduced abductor muscle strength were observed. Age, weight, and Pauwels classification were risk factors for femoral neck shortening. Femoral neck shortening decreased gait velocity and seemed to impair gait symmetry and physical functioning. In conclusion, internal fixation of femoral neck fractures results in permanent physical limitations. The relatively young and healthy patients in our study seem capable of compensating. Attention should be paid to femoral neck shortening and proper correction with a heel lift, as inadequate correction may cause physical complaints and influence outcome. PMID:23823040

    The principle of femoral shaft fracture reduction is to restore its pre-fractured limb length and mechanical axis. The current documented treatment method with traction table reduction does not conform to the quantitative alignment and reduction. There is also a great amount of X-Ray radiation exposure to both surgeon and patient during the procedure. For this reason, we introduced an innovated Parallel Manipulator Robot (PMR) application: A Femoral Shaft Fracture Reduction with Parallel Manipulator Robot on Traction Table. With this application, the quantitative control on fracture reduction and alignment can be achieved and the radiation exposure to both surgeons and patients can be greatly reduced. PMID:24110820

    Subchondral insufficiency fracture of the femoral head may be confused with osteonecrosis, mainly because of radiological overlap. SPECT/CT with Tc-99 m hydroxymethylene diphosphonate images in 7 patients with subchondral insufficiency fracture were retrospectively reviewed and compared with those from 11 patients with symptomatic early osteonecrosis. In all of the hips with subchondral insufficiency fracture, SPECT/CT showed increased uptake at the subchondral lesions of the femoral head. On the other hand, in all of the hips with osteonecrosis, absence of uptake was confirmed at the subchondral lesions. SPECT/CT may assist in differentiating subchondral insufficiency fracture from osteonecrosis. PMID:26164176

    An 82-year-old woman sustained a trochanteric fracture of the left femur after a fall. Fracture fixation was performed using proximal femoral nail antirotation (PFNA) II, and she was able to walk with a T-cane after 3 months. Eleven months following the operation, the patient presented with left hip pain after a fall. Radiographs showed a subchondral collapse of the femoral head located above the blade tip. The authors removed the PFNA-II and subsequently performed cemented bipolar hemiarthroplasty. Histological evaluation of the femoral head showed osteoporosis with no evidence of osteonecrosis. Repair tissue, granulation tissue and callus formation were seen at the collapsed subchondral area. Based on these findings, a traumatic subchondral fracture of the femoral head in a healed trochanteric fracture was diagnosed. A traumatic subchondral fracture of the femoral head may need to be considered as a possible diagnosis after internal fixation of the trochanteric fracture. PMID:25015169

    Abstract The goal of this study was to determine the incidence of avascular necrosis of the femoral head (AVNFH) after intramedullary nailing of femoral shaft fractures and to identify risk factors for developing AVNFH. We retrospectively reviewed all patients with femoral shaft fractures treated with antegrade intramedullary nailing at 10 institutions. Among the 703 patients enrolled, 161 patients were excluded leaving 542 patients in the study. Average age was 42.1 years with average follow-up of 26.3 months. Patient characteristics and fracture patterns as well as entry point of femoral nails were identified and the incidence of AVNFH was investigated. Patients were divided into 2 groups according to open versus closed physis, open versus closed fractures, and age (<20 versus ≥20 years). Overall incidence of AVNFH was 0.2% (1 of 542): the patient was 15-year-old boy. Of 25 patients with open physis, the incidence of AVNFH was 4%, whereas none of 517 patients with closed physis developed AVNFH (P < 0.001). The incidence of AVNFH in patients aged < 20 versus ≥20 years was 1.1% (1 of 93) and 0.0% (0 of 449), respectively (P = 0.172), which meant that the incidence of AVNFH was 0% in adult with femur shaft fracture. Of 61 patients with open fractures, the incidence of AVNFH was 0%. The number of cases with entry point at the trochanteric fossa or tip of the greater trochanter (GT) was 324 and 218, respectively, and the incidence of AVNFH was 0.3% and 0.0%, respectively (P = 0.412). In patients aged ≥20 years with isolated femoral shaft fracture, there was no case of AVNFH following antegrade intramedullary nailing regardless of the entry point. Therefore, our findings suggest that the risk of AVNFH following antegrade femoral nailing is extremely low in adult patients. PMID:26844518

    2016-01-01

    Introduction: Femoral shaft fracture is one of the typical bone fractures due to high energy trauma and may occur as an open fracture. Some foreign materials may enter the fracture site such as sand, cloth particles and so on. Case Presentation: A 28-year-old motorcycle riding military member and his collaborator were received in the hospital because of multiple traumas due to a fall in a hollow during a surveillance mission. His collaborator died because of head trauma and multiple severe open fractures. When fixing the patients femoral fracture, a large femoral butterfly fragment was removed from the patient’s thigh as a foreign segment. The patient’s femur was fixed with a plate and screws. No femoral defect was detected during surgery or post-operative X-rays and CT scan. The removed segment was not a part of the patient’s femur. Conclusions: Surgical and post-surgical findings showed that this segment was not related to the patient’s femur. The foreign segment may have belonged to the other victim of this trauma.

    Abstract Here, we report a case of a distal femoral fracture in a 23-year-old male army cadet who presented to the Accident and Emergency department following a twisting injury while participating in a routine military marching exercise. A pathological fracture was considered but this suspicion was put to rest following thorough investigations, leaving only a diagnosis of a nontraumatic spontaneous femoral fracture. To our knowledge, there have been no reported cases of distal femoral fractures associated with nontraumatic military exercises, with the majority of injuries instead related to stress fractures. A vigilant literature search yielded no cases of similar injury nature, which is the primary reason we believe that those interested in orthopaedics or military doctors would find themselves drawn to this case. The patient presented with severe pain in his left thigh and on examination there was a deformity of his left thigh. In terms of investigations, a bone profile, plain film radiographs, C-reactive protein, erythrocyte sedimentation rate, and tumor markers were all preformed and proved unremarkable. The definitive treatment was by open reduction and internal fixation. Femoral fractures often require significant amounts of force, particularly in young, healthy individuals. Generally, these injuries in this demographic follow high-energy traumas, with the lion's share occurring following a road traffic accident or other high-speed impact. More often than not, the treatment is surgical. Given the extraordinary manner of this such, one must be attentive and exhaustive in their investigation of such presentations. PMID:27258509

    Dislocation of the hip is a critical injury that results from high-energy trauma. This paper describes a case of posterior dislocation of the right hip in a 35-year-old woman with associated ipsilateral femoral head fracture. Initial treatment included reduction of the right hip through posterior approach and fixation of the femoral head fracture with three absorbable screws. After 15-month follow-up, a full range of motion has been achieved and there are no signs of avascular necrosis, hip instability, or limping. The authors describe their method of surgery.

    Introduction Although the subchondral portion of the femoral head is a common site for collapse in osteonecrosis of the femoral head (ONFH), femoral-neck fracture rarely occurs during the course of ONFH. We report a case of occult insufficiency fracture of the femoral neck without conditions predisposing to insufficiency fractures, occurring in association with ONFH. Presentation of case We report a case of occult fracture of the femoral neck due to extensive ONFH in a 60-year-old man. No abnormal findings suggestive of ONFH were identified on radiographs, and the fracture occurred spontaneously without any trauma or unusual increase in activity. The patient’s medical history, age, and good bone quality suggested ONFH as a possible underlying cause. Contrast-enhanced magnetic resonance imaging was useful in determining whether the fracture was caused by ONFH or was instead a simple insufficiency fracture caused by steroid use. Discussion The patient was treated with bipolar hemiarthroplasty, but if we had not suspected ONFH as a predisposing condition, the undisplaced fracture might have been treated by osteosynthesis, and this would have led to nonunion or collapse of the femoral head. To avoid providing improper treatment, clinicians should consider ONFH as a predisposing factor in pathologic fractures of the femoral neck. Conclusion ONFH should be included in the differential diagnosis of insufficiency fracture of the femoral neck. PMID:26275737

    Background Hip fractures are a major public health burden. In industrialized countries about 20% of all femoral fractures occur in care dependent persons living in nursing care and assisted living facilities. Preventive strategies for these groups are needed as the access to medical services differs from independent home dwelling older persons at risk of osteoporotic fractures. It was the objective of the study to evaluate the effect of a fall and fracture prevention program on the incidence of femoral fracture in nursing homes in Bavaria, Germany. Methods In a translational intervention study a fall prevention program was introduced in 256 nursing homes with 13,653 residents. The control group consisted of 893 nursing homes with 31,668 residents. The intervention consisted of staff education on fall and fracture prevention strategies, progressive strength and balance training, and on institutional advice on environmental adaptations. Incident femoral fractures served as outcome measure. Results In the years before the intervention risk of a femoral fracture did not differ between the intervention group (IG) and control group (CG). During the one-year intervention period femoral fracture rates were 33.6 (IG) and 41.0/1000 person years (CG), respectively. The adjusted relative risk of a femoral fracture was 0.82 (95% CI 0.72-0.93) in residents exposed to the fall and fracture prevention program compared to residents from CG. Conclusions The state-wide dissemination of a multi-factorial fall and fracture prevention program was able to reduce femoral fractures in residents of nursing homes. PMID:21918688

    The benefits of bisphosphonates are well documented, but prolonged use has been associated with atypical femur fractures. Radiographic markers for fracture predisposition could potentially aid in safer medication use. In this case-control designed study, we compared hip radiographic parameters and the demographic characteristics of chronic bisphosphonate users who sustained an atypical femoral fracture with a group of chronic bisphosphonate users who did not sustain an atypical femur fracture and also a group who sustained an intertrochanteric hip fracture. Radiographic parameters included were neck-shaft angle (NSA), hip-axis length (HAL) and center-edge angle (CE). Multivariate regression was used to evaluate the relationship between radiographic measures and femur fracture. Receiver-operating characteristic analysis determined cut-off points for neck-shaft angle and risk of atypical femur fracture. Ultimately, pre-fracture radiographs of 53 bisphosphonate users who developed atypical fracture were compared with 43 asymptomatic chronic bisphosphonate users and 64 intertrochanteric fracture patients. Duration of bisphosphonate use did not statistically differ between users sustaining atypical fracture and those without fracture (7.9 [±3.5] vs. 7.7 [±3.3] years, p=0.7). Bisphosphonate users who fractured had acute/varus pre-fracture neck-shaft angles (p<0.001), shorter hip-axis length (p<0.01), and narrower center-edge angles (p<0.01). Regression analysis revealed associations between neck-shaft angle (OR=0.89 [95% CI=0.81-0.97; p=0.01), center edge angle (OR=0.89 [95% CI=0.80-0.99]; p=0.03), and BMI (OR=1.15 [95% CI=1.02-1.31; p=0.03) with fracture development. ROC curve analysis (AUC=0.67 [95% CI=0.56-0.79]) determined that a cut-off point for neck-shaft angle <128.3° yielded 69% sensitivity and 63% specificity for development of atypical femoral fracture. Ultimately, an acute/varus angle of the femoral neck, high BMI, and narrow center-edge angle were

    We present a case of Klippel Trenaunay syndrome (KTS) who presented with severe bilateral knee osteoarthritis (OA). Preoperative planning was commenced for a total knee replacement (TKR). Whilst on the waiting list the patient suffered a fall and sustained a complete femoral diaphysis fracture. Conservative management in the form of skin traction was initially chosen as significant extra- and intramedullary vascular malformations posed an increased risk of perioperative bleeding. This failed to progress to union, and so open reduction and internal fixation was performed. This subsequently resulted in on-going delayed union, which was subsequently managed with low intensity pulsed ultrasound (LIPUS, otherwise known as Exogen (Bioventus. exogen. Secondary exogen, 2012)). There are only two previous documented cases of femoral fracture in KTS. This is the first report of a patient with this rare syndrome receiving this treatment. We discuss the management of fracture in this challenging group of patients. PMID:25478269

    Simultaneous fractures of the femoral neck and shaft are not common injuries, though they cannot be considered rare. Herein, we report our experience with a patient with bilateral occurance of this injury. Up to the best of our knowkedge this is the first case reported in literature in which correct diagnosis was made initially. Both femurs were fixed using broad 4.5 mm dynamic compression plate and both necks were fixed using 6.5 mm cannulated screws. Femur fixation on one side was converted to retrograde nailing because of plate failure. Both neck fractures healed uneventfully. In spite of rarity of concomitant fractures of femoral neck and shaft, this injury must be approached carefully demanding especial attention and careful device selection. PMID:25692158

    Background: Fractures of the knee account for about 6% of all trauma admissions. While its management is mostly focused on fracture treatment, it is not the only factor that defines the final outcome. Objectives: This study aimed to study objective and subjective outcomes after proximal tibial versus distal femoral fractures in terms of knee instability and health-related quality of life. Patients and Methods: This retrospective, cross-sectional, cohort study was carried out on 80 patients with either isolated proximal tibial (n = 42) or distal femoral (n = 38) fractures, who underwent open reduction and internal fixation. All the fractures were classified based on the Schatzker and AO classification for tibial plateau and distal femoral fractures, respectively. The patients were followed and examined by an orthopedic knee surgeon for clinical assessment of knee instability. In their last follow-up visit, these patients completed a Lysholm knee score and the short-form (SF) 36 health survey. Results: Among the 42 tibial plateau fractures, 25% were classified as Schatzker type 2. Of the 38 distal femoral fractures, we did not find any type B1 or B3 fractures. The overall prevalence of anterior and posterior instability was 42% and 20%, respectively. Medial Collateral Ligament (MCL) and Lateral Collateral Ligament (LCL) injuries were detected clinically in 50% and 28%, respectively. The incidence rates of ligament injuries in tibial plateau fractures were as follows: Anterior Collateral Ligament (ACL) 26%, Posterior Collateral Ligament (PCL) 7%, MCL 24%, and LCL 14%. Medial collateral ligament injury was the most common in the Schatzker type 2 (50% of the injuries). Distal femoral fractures were associated with ACL injury in 16%, PCL in 13%, MCL in 26% and LCL in 14%. However, final knee range of motion (ROM) and function (Lysholm score) were not associated with fracture location. No statistically significant difference was observed between the two groups, except for

    Background and purpose Use of bisphosphonates in women is associated with higher risk of atypical femoral fractures. The risk in terms of timing of use and type of bisphosphonate, and in men, remains unclear. Patients and methods We reviewed radiographs of 5,342 Swedish women and men aged 55 years or more who had had a fracture of the femoral shaft in the 3-year period 2008–2010 (97% of those eligible), and found 172 patients with atypical fractures (93% of them women). We obtained data on medication and comorbidity. The risk of atypical fracture associated with bisphosphonate use was estimated in a nationwide cohort analysis. In addition, we performed a case-control analysis with comparison to 952 patients with ordinary shaft fractures. A short report of the findings has recently been presented (Schilcher et al. 2014a). Here we provide full details. Results The age-adjusted relative risk (RR) of atypical fracture associated with bisphosphonate use was 55 (95% CI: 39–79) in women and 54 (CI: 15–192) in men. In bisphosphonate users, women had a 3-fold higher risk than men (RR = 3.1, CI: 1.1–8.4). Alendronate users had higher risk than risedronate users (RR = 1.9, CI: 1.1–3.3). The RR after 4 years or more of use reached 126 (CI: 55–288), with a corresponding absolute risk of 11 (CI: 7–14) fractures per 10,000 person-years of use. The risk decreased by 70% per year since last use. Interpretation Women have a higher risk of atypical femoral fracture than men. The type of bisphosphonate used may affect risk estimates and the risk decreases rapidly after cessation. PMID:25582459

    The femoral shaft is rarely the site of a low-energy fracture in a healthy individual. The vast majority of these fractures are due to major trauma such as motor vehicle accidents. Although low-energy femoral shaft fractures do occur, they are typically in patients with osteoporotic bone, or prosthesis related. In this case report, we present a man in his late 30s who was practising a specific yoga stance when he experienced a femoral shaft fracture. PMID:26452743

    Summary Atypical femoral fractures are often associated with prolonged bisphosphonate use. The American Society for Bone and Mineral Research (ASBMR) has set the diagnosis criteria for atypical subtrochanteric and diaphyseal femoral fractures by classifying them according to their major and minor criteria. Prolonged bisphosphonate use is correlated with AFF, but the pathogenetic mechanism that causes this kind of fracture has not been defined yet. We describe simultaneous bilaterally femoral fractures in a 76-year-old woman. PMID:27252749

    We investigated perioperative blood gas changes in 26 patients scheduled for surgical correction of femoral neck fracture under epidural anesthesia. Arterial blood gases during spontaneous air respiration were measured eight times during the femoral neck prosthetic replacements (n = 16), and four times during osteosynthesis (n = 10). In the patients who received femoral neck replacements using bone cement (n = 8), arterial oxygen tension decreased significantly four hours after insertion of prosthesis, and did not recover during two postoperative days. In contrast, in the patients who received cementless femoral neck replacements (n = 8), arterial oxygen tension tended to decrease but not significantly, and returned to normal on the second postoperative day. In the patients who received osteosynthesis, arterial oxygen tension did not change. We suspected that the causes of delayed hypoxia in the femoral neck replacements were vascular endothelial cell injury in the lung by free fatty acid originating from fat embolism, and/or microthrombosis resulting from activated coagulation system. Bone cement was thought to intensify fat embolism because of elevated intramedullary pressure in the femur. PMID:8953864

    Method: Between May 2012 and September 2014 cluster of five patients with large osteochondral fractures of the lateral femoral trochlea were treated at our institution. These all occurred in high level male athletes, one at a decathlete and the other four soccer players. The MRI scan showed a characteristic appearance of a large subchondral fracture involving most of the lateral femoral trochlea. All patients were symptomatic. The patients were treated with open reduction and internal fixation using headless compression screws. The operative technique and short term results will be outlined. Results: Fixation appears successful in most cases. Conclusion: This appears to be a repetitive trauma related injury that occurs in young high-level athletes.

    A robotic system with 6 DOF mobility was proposed for reduction of femoral shaft fractures based on Stewart platform. A plan for implementing the platform on bone fragments was introduced and a step by step strategy for performing the reduction procedure, based on the system's inverse kinematic solution, was proposed. The efficacy of the system was evaluated in some case studies and it was shown that it can be locked to act as an external fixator. PMID:19377143

    Objectives To examine, in the province of Alberta, temporal trends, regional variations in treatment options and in-hospital death rates after a femoral neck fracture. Design A retrospective cohort study. Patients Six years’ data were abstracted from the Alberta Morbidity File, the Alberta Health Stakeholder File and the Alberta Health Care Claims File. Patients were included if they were Alberta residents, aged 65 years or older, had sustained a femoral neck fracture and had undergone internal fixation, hemiarthroplasty or total hip arthroplasty. Main outcome measures Death rates, arthroplasty rates and hospital stay. Results In-hospital death rates were similar across hospitals, with risks being higher for men, patients aged 80 years or older and those with more comorbid conditions. Arthroplasty rates varied from 58% to 77% among hospitals, and hospital stays associated with arthroplasty were significantly longer than those associated with internal fixation. The chance of undergoing arthroplasty varied from hospital to hospital by gender and by the number of comorbid conditions. Conclusion Regional variations suggest lack of agreement among Alberta’s surgeons as to how best to treat femoral neck fractures. PMID:12174977

    Introduction: Fractures involving bones containing a component of a prosthetic joint are becoming more common. The causation is multifactorial but most of these injuries are associated with trivial trauma. The options available for operative management of these fractures include internal fixation of the fracture alone, fixation of the fracture with revision of the prosthesis, and reconstruction of proximal femur with either modified impaction bone grafting or proximal femoral replacement. Case Report: We present here a case of periprosthetic fracture Vancouver type B1 with a broken cemented bipolar prosthesis insitu, in which the broken implant was firmly fixed in the proximal fragment and could not be removed following which the whole of the proximal fragment along with the broken implant was removed and replaced by a customized steel long stem cemented mega prosthesis. Conclusion: This case is being presented on account of its unusual presentation and fracture pattern. A broken prosthesis along with a periprosthetic fracture is not a common incident. Thus the treatment had to be individualized. Since the prosthesis was well fixed, its broken stem could not be removed from the proximal fragment and so the whole of the proximal fragment along with stem was removed and replaced with a long stem custom made bipolar prosthesis.

    2014-01-01

    Hoffa fracture is a rare injury consisting of unicondylar tangential posterior fracture of the distal femur and only very few cases have been reported in the literature. These fractures are due to high energy trauma and conservative treatment generally yields poor results, but rigid internal fixation allows early functional rehabilitation and decreases the incidence of complications. The purpose of the study was to prospectively analyse the clinico-radiological and functional outcome following open surgical treatment. From July 2005 to July 2010, 22 patients (14 males and 8 females) were recruited from Emergency and outpatient department having closed and open Hoffa fracture of the femoral condyle. All patients were operated under general or spinal anesthesia. Post-operatively, all the patients were followed for 12 months. Fractures were united in a mean time of 10 weeks (range from 6 - 16 weeks) depending on the type of fracture pattern. Fractures were reduced anatomically in all except in one patient. During follow-up, there were no losses of reduction or fixation. Full weight bearing were started in the mean time of 8.8 weeks. Mean duration of hospital stay were 9.8 days. Complications were stiffness and pain in one patient, collateral laxity in one patient and progression of arthritis in one patient. The results were excellent in 90.90% and good in 9.09% patients. Finally, we conclude that the early anatomical reduction and rigid fixation with screws provide best results and minimal complications. PMID:25130151

    Artificial cadaveric femoral neck fractures were internally fixed with five different devices and subjected to cyclical loading of 0-1.0 kilonewtons (approximately one body weight) whilst in an anatomical position. Displacement of the proximal fragment was detected by a transducer and charted. Bone strength was assessed by a preliminary control loading phase on the intact bone. Efficiency of each fracture fixator could then be directly compared by the relative movement in each case. Five specimens each were tested with Moore's Pins, Trifin Nail, Garden Screws and a sliding screw-plate (OEC Ltd). By the criteria of the experiment, which put a severe shearing load on the implant, none of these devices reliably bore the representative body weight. An extended barrel-plate, which supported the sliding screw almost up to the fracture line, was then made. This device, employing some of Charnley's concepts, tolerated body weight in four cases out of five. PMID:6887186

    Background The treatment of unstable intertrochanteric fractures in elderly is still controversial. The purpose of this study is to present treatment strategies for unstable intertrochanteric fractures with hemiarthroplasty using standard uncemented collared femoral stems and at the same time preserving the fractured calcar fragment. Methods Fifty-four patients aged 75 years or older with unstable intertrochanteric fractures were included in this prospective cohort study. All patients were treated with calcar preserving hemiarthroplasty using cementless collored femoral stems. Fractured calcar fragment was stabilized either by compaction between the implant and femur or fixed with cable grip system. Follow-up evaluations were performed at least 24 months and later. Palmer and Parker mobility score and visual analogue scale (VAS) pain score were assessed. We also analyzed radiographs of the operated hip at each follow-up visit. Results The patients were 15 males and 39 females with a mean age of 81.3 years (range, 75 to 93 years). The average operative time was 86.6 minutes. The mean transfused blood units were 1.2 units. The average duration of hospital stay was 5.3 days. The preoperative mean mobility score was 6.20. This score was found to be 4.96 on postoperative third day and 5.90 at 24 months postoperatively. The results of the statistical analysis revealed significant increase in the mobility scores at each follow-up after three days. Radiological interpretation revealed no loosening in the cable-grip systems, and no significant subsidence (> 5 mm) of prosthesis was observed. Conclusions Calcar preservation arthroplasty is a good option for elderly patients with severe osteoporosis, frail constitution and the patients who are at higher risk for second operation due to unstable intertrochanteric fractures.

    Background: Management of periprosthetic supracondylar femoral fractures is difficult. Osteoporosis, comminution and bone loss, compromise stability with delayed mobility and poor functional outcomes. Open reduction and internal fixation (ORIF) with anatomic distal femoral (DF) locking plate permits early mobilization. However, this usually necessitates bone grafting (BG). Biological fixation using minimally invasive techniques minimizes periosteal stripping and morbidity. Materials and Methods: 31 patients with comminuted periprosthetic DF fractures were reviewed retrospectively from October 2006 to September 2012. All patients underwent fixation using a DF locking compression plate (Synthes). 17 patients underwent ORIF with primary BG, whereas 14 were treated by closed reduction (CR) and internal fixation using biological minimally invasive techniques. Clinical and radiological followup were recorded for an average 36 months. Results: Mean time to union for the entire group was 5.6 months (range 3-9 months). Patients of ORIF group took longer (Mean 6.4 months, range 4.5-9 months) than the CR group (mean 4.6 months, range 3-7 months). Three patients of ORIF and one in CR group had poor results. Mean knee society scores were higher for CR group at 6 months, but nearly identical at 12 months, with similar eventual range of motion. Discussion: Locked plating of comminuted periprosthetic DF fractures permits stable rigid fixation and early mobilization. Fixation using minimally invasive biological techniques minimizes morbidity and may obviate the need for primary BG. PMID:26015610

    Objective: We wanted to analyze the factors affecting the results of multiple cannulated screws fixation in patients less than 60 years old with femoral neck fracture (FNF). Methods: We reviewed 52 patients (30 males, 22 females) who were treated with multiple cannulated screws fixation for FNFs. They were followed up for more than one year during January 2002 to December 2012. They were classified by Garden’s classification. The anatomic reduction was evaluated by Garden’s alignment index on hip both anteroposterior and lateral images. Postoperative complications were analyzed during follow up periods. Results: By Garden’s classification, 6 cases were in stage I, 13 cases in stage II, 30 cases in stage III and 3 cases in stage IV. During follow up periods, avascular necrosis of the femoral head was observed in 12 cases (23%) and nonunion was observed in 5 cases (9%). The 16 patients who had complications underwent total hip arthroplasty (31%). In non-displaced fracture groups (Garde I, II) did not have AVN nor nonunion. The incidence of complications in displaced fracture group was 51.5%. The complicated cases showed tendency for increased apex anterior angulation of femoral neck on hip lateral images and the result was statistically significant. (p=0.0260). Conclusion: The patients less than 60 years old who were treated with multiple cannulated screws fixation for displaced FNFs showed the incidence of complications was more than 50%. It needs a cautious approach for anatomical reduction, especially related to anterior angulation on hip lateral image. PMID:26870127

    Displaced femoral neck fractures in physiologically young patients are best treated with anatomic reduction and stable fixation. Several surgical approaches to the femoral neck have previously been described, although they are fraught with disadvantages such as poor visualization, the need for 2 incisions, and risk of injury to the lateral femoral cutaneous nerve and branches of the medial femoral circumflex artery. The authors' hybrid anterolateral approach to the hip allows for excellent visualization of femoral neck fractures and for placement of plate and/or screw constructs through a single incision. This surgical technique additionally minimizes risk to neurovascular structures. PMID:26186310

    Recently, we experienced a case where the diagnosis and management of a deep femoral artery rupture was delayed. This vascular complication occurred during the insertion of a distal interlocking screw of a proximal femoral nail for the fixation of an intertrochanteric femur fracture. A 79-year-old male patient was diagnosed with a right intertrochanteric fracture after a fall. We fixed the fracture with a proximal femoral nail (Zimmer® Natural Nail™ System). One day after the procedure, the patient complained of pain and swelling on the anteromedial side of his middle thigh followed by hypotension, anemia and prolonged thigh swelling. Computed tomography angiography was performed 7 days after the procedure. We found a pseudoaneurysm of the perforating artery caused by injury to the deep femoral artery and an intramuscular hematoma in the anterior thigh muscle. We successfully treated the pseudoaneurysm using coil embolization. Throughout the management of intertrochanteric femoral fractures, it is important to be aware and monitor signs and symptoms related to the possibility of blood vessel damage. When a patient presents with swelling and pain on the middle thigh and/or unexplained anemia postoperatively, the possibility that these symptoms are caused by an injury to the femoral artery must be considered.

    Ipsilateral femoral neck and shaft fractures are rare injuries, which are often caused by high-energy trauma and combined with multiple injuries, such as thoracic and abdominal injury, head injuries, and fractures of other sites.Delayed or missed diagnosis of the ipsilateral femoral neck fracture often occurs.When patients with femoral shaft fractures caused by high-energy trauma are admitted into hospital, physical examination should be conducted carefully.In addition to femoral shaft fractures, radiographs of the ipsilater hip and knee joints should been taken, simultaneously taking into consideration the potential effect of anteversion angle on the demonstration of femoral neck fracture.Computed tomograph and magnetic resonance imaging are advised to perform if necessary to facilitate early and accurate diagnosis of ipsilateral femoral neck fracture.Comprehensive evaluation should be done based on age, physical condition, associated injuries as well as fracture site, classification and injury severity.Accordingly, proper and reasonable surgical plan is made.During the operation, anatomical reduction of the fractures, especially femoral neck fractures, should be achieved, and then fixed with appropriate internal implants.Besides, attention should also be paid to the treatment of associated injuries as well as the prevention and management of complications.

    Background Recently, various femoral head fixation devices (HFDs) for trochanteric fractures have become available. However, there are some cases in which femoral head rotation with excessive sliding of the HFD is observed and it is often followed by cutout. The purpose of this study is to compare the ability of the three types of HFDs to prevent femoral head rotation. Methods Between July 2005 and December 2009, 206 patients aged over 60 years with trochanteric fractures who had undergone surgical treatment using a short femoral nail in our institution were enrolled into the study. We used the gamma 3 nail (GMN) as the screw-type HFD in 66 cases, the gliding nail (GLN) as a non-cylindrical blade in 76 cases, and the proximal femoral nail antirotation (PFNA) as a cylindrical blade in 64 cases. The sliding length of HFDs and the occurrence of femoral head rotation were evaluated by assessing radiographs as the main outcome, and the results were compared among these devices. Results A comparison of the degree of sliding in the GMN group showed that femoral head rotation was observed significantly more frequently in cases with rotation. Further, it appeared that femoral head rotation occurred more frequently in comminuted fractures. However, no significant differences between the sliding lengths of the different HFDs were observed among three groups. Femoral head rotation was observed in 15 cases of GMN (22.7%), 0 case of GLN, and 5 case of PFNA (7.8%). Significant differences with regard to the occurrence of femoral head rotation were observed among the three groups. Furthermore, significant differences were also observed between GLN and PFNA with respect to the occurrence of femoral head rotation. Conclusions The ability to stabilize femoral head appears to be greater with blade-type materials than with screw-type materials. Furthermore, we believe that a non-cylindrical blade is preferable to a cylindrical blade for the surgical treatment of comminuted, unstable

    Aim: To compare the efficacies of four surgical treatments, i.e., total hip arthroplasty (THA), internal fixation (IF), hemiarthroplasty (HA), and artificial femoral head replacement (artificial FHR), by performing a network meta-analysis based on Harris hip score (HHS) in elderly patients with femoral neck fracture. Methods: In strict accordance with specific inclusion and exclusion criteria, randomized controlled trails (RCTs) were screened and selected from a larger group of studies that were retrieved through a comprehensive search of scientific literature databases, further complimented by manual search. The resultant high-quality data from final selected studies were analyzed using Stata 12.0 software. Results: A total of 3680 studies were initially retrieved from database search, and 15 RCTs were eventually incorporated into this meta-analysis, containing 1781 elderly patients who had undergone various surgical treatments for femoral neck fracture (THA group = 604; HA group = 604; IF group = 495; artificial FHR group = 78). Our major result revealed a statistically significant difference in HHS of femoral neck fracture when HA and IF groups were compared with THA. No differences were detected in the HHS of femoral neck fracture undergoing artificial FHR and THA. The surface under the cumulative ranking curves (SUCRA) value of HHS, in elderly patients with femoral neck fracture after surgery, revealed that IF has the highest value. Conclusions: The current network meta-analysis results suggest that IF is the superlative surgical procedure for femoral neck fracture patients, and IF significantly improves the HHS in femoral neck fracture patients.

    Background & objectives: Bisphosphonates (BPs) are the most widely prescribed medicines for the treatment of osteoporosis because of their efficacy and favourable safety profile. There have been, several reports on an increased incidence of atypical femoral fractures after long term treatment with BPs. The objective of this study was to evaluate the clinical presentation including prodromal symptoms, skeletal radiograph findings, type and duration of BPs received and treatment outcome of patients who developed atypical femoral fractures during bisphosphonate therapy. Methods: In this retrospective study, eight patients with atypical femoral fractures were analysed based on clinical features, biochemical and radiological investigations. Results: Of the eight patients, who sustained atypical femoral fractures, six were on alendronate and two were on zoledronate therapy before the fractures. In addition to BPs, two patients were on long term corticosteroid therapy for rheumatoid arthritis and Addison's disease. Three patients had bilateral atypical femoral fractures. Except one, all of them had prodromal symptoms prior to fracture. Skeletal radiograph showed cortical thickening, pointed (beaking of) cortical margin and transverse fracture in meta-diaphyseal location. Serum calcium, phosphate, alkaline phosphatase (ALP) and intact parathyroid hormone (iPTH) concentrations were within the reference range in all patients. Interpretation & conclusions: Long term bisphosphonate therapy may increase the risk of atypical femoral fractures. Presence of prodromal pain, thickened cortex with cortical beaking may be an early clue for predicting the atypical fractures. High risk patients need periodical skeletal survey and a close follow up for early detection of cases. PMID:25222777

    Unilateral femoral neck factures are common and their incidence is increasing. However, simultaneous bilateral femoral neck fractures are rare. Although cases of simultaneous bilateral femoral neck fractures have been reported, most were caused by strong muscle contractions during electroconvulsive therapy. Simultaneous bilateral femoral neck fractures caused by a simple fall are an extremely rare injury; therefore, limited literature is available, and no case has been reported in Korea. We report herein a case of simultaneous bilateral femoral neck fractures caused by a simple fall. An 83-year-old woman visited the emergency department with bilateral hip joint pain and gait disturbance, which developed 1 day after a fall. Tenderness and severe limitation in left hip joint range of motion and mild limitation in right hip joint range of motion were observed on a physical examination. A Garden type IV femoral neck fracture in the left hip joint and a Garden type I femoral neck fracture in the right hip joint were observed on plain radiography. She underwent right screw fixation and left bipolar hemiarthroplasty 2 days after admission. The patient could walk using a walker 4 weeks postoperatively. Bone union in the right femoral neck was observed at the 3 month follow-up. No specific findings were observed at the left hip hemiarthroplasty site.

    Objective: To epidemiologically and clinically evaluate patients with displaced femoral neck fractures that were surgically treatment with cemented hip hemiarthroplasty. Methods: All patients with displaced femoral neck fractures (Garden III and IV) who underwent cemented hip hemiarthroplasty using a unipolar prosthesis (Thompson), by means of a posterolateral access between June 2005 and September 2008 were retrospectively evaluated. Results: Seventy patients were initially evaluated. Their mean age was 83.1 years. The patients were predominantly female (84.3%). Thirty-six patients were monitored as outpatients for periods ranging from 10 to 48 months (mean of 26.5 months). Fifteen patients were lost to follow-up. Nineteen patients died, and the mortality rate within the first year was 25.4%. Patients classified as ASA III had a mortality rate of 25.7% and ASA II patients, a rate of 12.1%. Two patients had symptomatic deep vein thrombosis; one patient had an operative wound infection; and none of the patients presented hip dislocation. Most of the patients did not experience pain. Twelve patients (33%) showed deterioration of their walking ability. Conclusion: There were no cases of hip dislocation. Patients classified as ASA III had a higher mortality rate than did patients with ASA I or II. There was a worsening of walking ability in 33% of the patients. No revision due to loosening or pain was needed for any patient. Thirty patients did not present any pain (83.3%), four presented moderate pain (11.1%) and two presented intense pain (5.5%).

    A retrospective study was made of all radionuclide (RN) bone images performed at our institution over a two-year period to evaluate femoral head viability after nonpathologic fracture of the femoral neck. Twelve patients had avascular femoral heads during the perioperative period, of which nine had adequate follow-up. Seven of these nine patients had follow-up bone images. Revascularization occurred in four patients, while three had persistent absence of femoral head uptake. With clinical follow-up ranging from four to 29 months (median: 14 months), only two of these nine patients developed clinical or radiographic evidence of osteonecrosis. RN bone imaging performed in the perioperative period does not reliably predict the development of post-traumatic osteonecrosis of the femoral head and, at present, should not be used to determine prospectively method of treatment of femoral neck fracture.

    As anatomical reduction of the articular surface of femoral head fractures and restoration of damaged cartilage are essential for good long-term results, many treatment options have been suggested, including fixation of the fracture using various surgical exposures and implants, as well as arthroscopic irrigation and debridement, bone marrow stimulating techniques, osteochondral allograft, autograft, and autogenous chondrocyte implantation. We report a case of osteochondral autograft harvested from its own femoral articular surface through surgical hip dislocation. The osteochondral graft was harvested from the inferior non-weight-bearing articular surface and grafted to the osteochondral defect. One year later, the clinical and radiological results were good, without the collapse of the femoral head or arthritic change. This procedure introduced in our case is considered convenient and able to lessen surgical time without morbidity of the donor site associated with the harvest. PMID:27593886

    Abstract The aim of this study was to compare the effectiveness and safety of 2 surgical techniques that are used to treat proximal femoral fractures. A systematic literature search (up to December 2014) was conducted in Medline, Embase, PubMed, and The Cochrane Central Register of Controlled Trials to screen for studies comparing proximal femoral nail antirotation (PFNA) with less invasive stabilization system–distal femur (LISS-DF) for proximal femoral fractures. Two authors independently assessed the methodological quality of the included studies and extracted data. Surgical information and postoperative outcomes were analyzed. A total of 7 studies with 361 patients who satisfied the eligibility criteria included 3 randomized controlled trials and 4 case-controlled trials associated with PFNA versus LISS in treating proximal femoral fractures. Our results demonstrated that there was a significant reduction in hospital stay and time to weight-bearing ambulation and bone healing for PFNA compared with LISS (odds ratio [OR] −1.48, 95% confidence interval [CI] −2.92 to −0.05; OR −7.08, 95% CI −8.32 to −5.84; OR −2.71, 95% CI −4.76 to 0.67). No statistically significant difference was observed between the 2 groups for operative time, blood loss volume, Harris hip score, and incidence of complications. Based on the results of this analysis, we inferred that PFNA is safer and more effective than reverse LISS-DF in patients undergoing osteosynthesis for proximal femoral fractures, and that PFNA is associated with reduced hospital stays and reduced time to weight-bearing ambulation and bone healing. Nonetheless, in certain cases in which PFNA is not suitable due to abnormal structure of the proximal femur or particularly unstable fractures, the LISS plate technique could be a useful alternative.

    BACKGROUND: Cross-match practice for patients with femoral neck fractures continues to cause concern due to a failure of compliance to the existing protocols. To address this issue, a number of studies were conducted over a 3-year period. METHODS: First, the existing cross-match practice for patients admitted with femoral neck fractures was reviewed to demonstrate the deficiencies within the system. Second, the opinion of anaesthetic and orthopaedic trainees was assessed regarding blood requirements for different femoral neck fractures following surgery and the justification of their perceptions. RESULTS: A summation of the studies is reported which demonstrates the reasons for the poor compliance to previous protocols. CONCLUSIONS: A simple and effective protocol is provided that has helped reduce pre-operative cross-matching of femoral neck fractures from 71% to 16.7% when assessed 2 years after its introduction.

    Femoral neck fractures account for nearly half of all hip fractures with the vast majority occurring in elderly patients after simple falls. Currently there may be sufficient evidence to support the routine use of hip replacement surgery for low demand elderly patients in all but non-displaced and valgus impacted femoral neck fractures. However, for the physiologically young patients, preservation of the natural hip anatomy and mechanics is a priority in management because of their high functional demands. The biomechanical challenges of femoral neck fixation and the vulnerability of the femoral head blood supply lead to a high incidence of non-union and osteonecrosis of the femoral head after internal fixation of displaced femoral neck fractures. Anatomic reduction and stable internal fixation are essentials in achieving the goals of treatment in this young patient population. Furthermore, other management variables such as surgical timing, the role of capsulotomy and the choice of implant for fixation remain controversial. This review will focus both on the demographics and injury profile of young patients with femoral neck fractures and the current evidence behind the surgical management of these injuries as well as their major secondary complications.

    Femoral stem fracture is an uncommon reason for the failure of total hip arthroplasty, with only 16 cases of fully coated stem fractures reported to date. Here we report a case in which a fully coated primary femoral stem fracture occurred after conversion to total hip arthroplasty for the non-union of an intertrochanteric fracture of the femur. Metallurgic evaluation of the etiology and mechanism revealed that the fracture was initiated by fatigue-related failure and completed by ductile failure on the posterior side of the fracture. Considering the recent trend of treating an intertrochanteric fracture with hip arthroplasty, possible stem failure should be considered, since most patients will have at least one of the known risk factors for stem fracture.

    Introduction Subtrochanteric femoral fractures are relatively uncommon, accounting for 7–15% of all hip fractures and treatment of these fractures are considered challenge for orthopaedic surgeons. Although several treatment options are reported with up to 90% of satisfactory results, the choice of the appropriate implant is still a matter of debate. Some authors reported thermal injury after reaming for intramedullary nail fixation in patients with narrow medullary canal. Presentation of case A 21-year-old female patient was admitted to our hospital because of right subtrochanteric femoral fracture. The narrowest diameter of medullary canal of her femur was about 7 mm but she refused open reduction and internal fixation with plate due to large scar formation. We used expert tibia nail instead of femoral intramedullary nail to prevent thermal injury. Discussion Subtrochanteric femoral fractures are difficult to treat because of their biomechanical and anatomical characteristics. Although several implants are reported for the surgical treatment of these fractures, intramedullary nails have been advocated due to their biological and biomechanical advantages. However, under certain circumstances with associated injury or anatomic difference we might consider another treatment options. Conclusion Expert tibia nail may be considered one of the treatment options for subtrochanteric femoral fracture with narrow medullary canal. We also emphasize the importance of preoperative evaluation of the medullary canal size for these risky fractures. PMID:25839435

    Hemangioma is a common disease; however, intramuscular hemangioma (IH) presenting with a pathological fracture is extremely rare. The present study reports a case of a 46-year-old male patient that suffered from IH of the right thigh, presenting with a pathological femoral fracture. The patient was initially diagnosed with a traumatic femoral fracture, and routine open reduction and internal fixation were performed at a local hospital. However, 20 days subsequent to surgery, gradual swelling and soreness around the incision were observed. The incision eventually ruptured during squatting for bowel movement, which led to extensive blood loss. Based on computed tomography (CT) and deep femoral artery arteriography, IH presenting with a pathological femoral fracture was diagnosed. The patient underwent artery embolization, from which he recovered well. At the 6-month follow-up, the femoral fracture was revealed to have healed, and a CT scan demonstrated no evidence of recurrence; however, continuous observation using CT is required in order to determine the long-term outcome. To the best of our knowledge, this is the first case of a misdiagnosed pathological femoral fracture in a patient with IH reported in the English literature. PMID:27347124

    Over the past decade there have been increasing reports of atypical femoral fractures (AFFs) associated with bisphosphonate use. Reported cases of bilateral involvement usually refer to sequential injuries, or a complete fracture with an incomplete injury to the contralateral limb. In this case report we describe simultaneous, bilateral, complete atypical femoral fractures following a simple fall. A history of prodromal pain, previous radiological evidence of cortical thickening and long term alendronate therapy for osteoporosis secondary to corticosteroid treatment paint a classical picture of the presentation of an atypical fracture pattern of which orthopaedic surgeons should be aware.

    Fracture of the femoral component associated with polyethylene wear and osteolysis after total knee arthroplasty (TKA) has not been well reported before. A 63-year-old man with osteoarthritis of the right knee underwent TKA with a New Jersey LCS Knee, with cementing on the tibia and patella but not on the femoral component. After 42 months, in addition to wearing of polyethylene of the tibia and patella, severe osteonecrosis of the medial femoral condyle was noted. Osteonecrosis caused loss of osseous support of the medial flange of the femoral component, and the bone ingrowth of the central and lateral flange to the distal femur was so good that it overcame the yield stress of the metal of the femoral component and caused fracture of the femoral component. The osteolytic area was filled with autogenous iliac bone, and a new femoral component was inserted and cemented. The patient's condition became satisfactory with relief of pain. Although uncommon, fracture of the femoral component does occur associated with polyethylene wear and osteolysis. PMID:10220194

    The purpose of this study was to assess the impact of deep wound infection after surgery for proximal femoral fracture (PFF) on the patient in terms of mortality and social consequences, and on the National Health Service in terms of financial burden. Sixty-one cases of PFF over a six-year period were complicated with deep surgical wound infection. These cases were compared with a matched control group of 122 patients without infection. Infected cases had greatly increased hospital stay (P<0.001), were 4.5 times less likely to survive to discharge (P=0.002), and if they survived, were three times less likely to return to their original residence (P=0.05). The total cost of treatment per infected case was 24,410 pound sterling compared with 7210 pound sterling for controls (P<0.001). Meticillin-resistant Staphylococcus aureus (MRSA) infection increased admission length and cost compared with non-MRSA infection (P=0.02). Deep wound infection after PFF is a devastating and costly complication for both the patient and the healthcare services. The cost consequences should be considered when allocating resources to trauma services to ensure adequate provision to minimize infection risks and to accommodate treatment costs in this vulnerable group.

    We describe a patient with autosomal-dominant osteopetrosis, a subtrochanteric fracture, and an ipsilateral femoral neck fracture treated with a hip spica cast Although the fracture united with coxa vara and external rotation deformities, the patient successfully returned to his normal activities of daily living. Operative fracture treatment in patients with osteopetrosis is difficult, and our patient provides evidence that with nonoperative treatment these patients can return to a functional level when operative treatment is not an option.

    Introduction: The anterior dislocation of the hip represents only a small percentage of all hip dislocations: 85% are posterior. Most commonly associated with this dislocation is a fracture of the femoral head and, in rare cases, a femoral neck fracture. We have found in literature no report of an anterior dislocation of the hip associated with femoral neck fracture, pelvic retention of the head and ureteral fistula. We report such a case of a 68 year old male. Case Report: A 68 year old male was presented to our attention, following a severe injury of the hip when falling from a high bridge, with severe pain in the hip and a clinical aspect of femoral neck fracture. The X-ray confirmed the femoral neck fracture but following an anterior dislocation with the head retained into the pelvis. The patient also had hematuria. An Austin Moore prosthesis was implanted for the femoral neck fracture and the head was extracted by the urologist by a new abdominal incision. Urological evaluation revealed a fistula of the ureter, treated by an internal drainage for three months. One month later the Moore prosthesis was extracted and the patient had a Girldestone hip for 5 months. Revision with a Muller cemented prosthesis had a normal evolution. Conclusion: The anterior fracture dislocation of the hip with pelvic retention of the femoral head and ureteral fistula is a rare condition resulting from high energy trauma. A multidisciplinary team is necessary to diagnose and treat fracture and soft tissue lesions. Early diagnosis and treatment is necessary to avoid septic complications. PMID:27298980

    The aim of this study was to quantify the stability of fracture-implant complex in fractures after fixation. A total of 15 patients with an undisplaced fracture of the femoral neck, treated with either a dynamic hip screw or three cannulated hip screws, and 16 patients with an AO31-A2 trochanteric fracture treated with a dynamic hip screw or a Gamma Nail, were included. Radiostereometric analysis was used at six weeks, four months and 12 months post-operatively to evaluate shortening and rotation. Migration could be assessed in ten patients with a fracture of the femoral neck and seven with a trochanteric fracture. By four months post-operatively, a mean shortening of 5.4 mm (-0.04 to 16.1) had occurred in the fracture of the femoral neck group and 5.0 mm (-0.13 to 12.9) in the trochanteric fracture group. A wide range of rotation occurred in both types of fracture. Right-sided trochanteric fractures seem more rotationally stable than left-sided fractures. This prospective study shows that migration at the fracture site occurs continuously during the first four post-operative months, after which stabilisation occurs. This information may allow the early recognition of patients at risk of failure of fixation. PMID:25737524

    Fracture of the femoral head and the acetabulum with traumatic dislocation of the hip is a severe injury representing various types and unfavorable outcome. We showed a 45-year-old man with Pipkin type-IV fracture and coxa valga. An immediate closed reduction was achieved followed by open reduction and internal fixation via a posterior approach 6 days later. However, dislocation occurred three times without traumatic events after three weeks. CT demonstrated no displacement of posterior fragments or implant failure. Femoral intertrochanteric varus osteotomy was performed to gain concentric stability and successfully resolved recurrent dislocation. Another 45-year-old woman with Pipkin type-IV fracture and coxa valga also underwent closed reduction initially and then continued conservative treatment. After eight weeks, when she started gait training, progressive pain became symptomatic. Persistent hip pain at weight bearing was not improved in spite of arthroscopic synovectomy and osteochondroplasty. Two years after injury, femoral intertrochanteric varus osteotomy was indicated and her refractory pain was resolved gradually. We suggest that femoral varus osteotomy should be considered for superolateral subluxation associated fracture dislocation of the hip in Pipkin type-IV and coxa valga. PMID:27293934

    2012-01-01

    Periprosthetic fractures of the femur in association with total hip arthroplasty are increasingly common and often difficult to treat. Patients with periprosthetic fractures are typically elderly and frail and have osteoporosis. No clear consensus exists regarding the optimal management strategy because there is limited high-quality research. The Vancouver classification facilitates treatment decisions. In the presence of a stable prosthesis (type-B1 and -C fractures), most authors recommend surgical stabilization of the fracture with plates, strut grafts, or a combination thereof. In up to 20% of apparent Vancouver type-B1 fractures, the femoral stem is loose, which may explain the high failure rates associated with open reduction and internal fixation. Some authors recommend routine opening and dislocation of the hip to perform an intraoperative stem stability test to rule out a loose component. Advances in plating techniques and technology are improving the outcomes for these fractures. For fractures around a loose femoral prosthesis (types B2 and 3), revision using an extensively porous-coated uncemented long stem, with or without additional fracture fixation, appears to offer the most reliable outcome. Cement-in-cement revision using a long-stem prosthesis is feasible in elderly patients with a well-fixed cement mantle. It is essential to treat the osteoporosis to help fracture healing and to prevent further fractures. We provide an overview of the causes, classification, and management of periprosthetic femoral fractures around a total hip arthroplasty based on the current best available evidence. PMID:23569704

    Subcapital fracture of the femur is common in the elderly patients though the incidence is less in our environment than in the western world. Primary prosthetic replacement is the method of treatment in the majority of the patients. To facilitate this, a foreknowledge of the femoral head diameter is necessary. To determine the diameter of the femoral head and its magnification on radiograph among patients with hip fractures seen in South-West Nigeria, all patients with subcapital fracture of the neck of femur seen between March 1997 and February 2002 were included in the study. The femoral heads were measured on the radiographic film using a transparent ruler and after extraction of the femoral head during surgery using callipers. There were 25 patients in all, the mean age of patients was 73.2 years. Fall at home accounted for 70% of the cases. The femoral head diameter was between 42 mm and 50 mm in 92% of patients while magnification of femoral head diameter on radiograph was 10-14% in 92% of cases. The usaof 10-14% magnification of femoral head on radiograph would help the surgeon determine the size of prosthetic head before commencement of surgery. PMID:15819470

    Background Intramedullary nailing has become the treatment of choice for closed femoral shaft fractures in children and adolescents. Immediate intramedullary nailing of open fractures of femur in children remains controversial, with most surgeons preferring to treat grade II or III open fractures either by debridement and traction or external fixation. The aims The aim of this study is to evaluate the results of intramedullary nailing of open femoral fractures in children. Methods 172 children were treated for femoral shaft fracture in our department. 19 fractures were opened in 18 patients. Results In children with polytrauma, multiple fractures, head injuries and other conditions which necessitate intensive nursing care, intramedullary nailing of opens femoral shaft fractures (type I, II, IIIA, IIIB) should be preferred. Conclusion Satisfactory results were obtained in all patients in terms of self evaluation of patients, radiological and clinical evaluation. The infection rate was much lower for patients who had been given a cephalosporin than for patient who had been given a penicillin or had been given no antibiotic. PMID:25104890

    Summary Distal femoral fractures have typically a bimodal occurrence: in young people due to a high-energy trauma and in older people related to a low-energy trauma. These fractures are associated to a very high morbidity and mortality in elderly. Distal femoral fractures might be treated with plates, intramedullary nails, external fixations, and prosthesis. However, difficulties in fracture healing and the rate of complications are important clinical issues. The purpose of this retrospective review was to present our experience in treatment of distal femoral fracture in a sample of older people in order to evaluate the technical pitfalls and strategies used to face up the fractures unsuccessfully treated with locking plates. We included people aged more than 65 years, with a diagnosis of distal femoral fracture, treated with locking plates. We considered ‘unsuccessfully treated’ the cases with healing problems or hardware failures. Of the 12 patients (9 females and 3 males; mean aged 68.75 ± 3.31 years) included, we observed 3 ‘unsuccessfully cases’, 2 due to nonunions and 1 due to an early hardware failure, all treated using a condylar blade plate with a bone graft. One patient obtained a complete fracture healing after 1 year and in the other cases there was a nonunion. We observed as most common technical pitfalls: inadequate plate lengthening, fracture bridging, and number of locking screws. The use of locking plates is an emerging technique to treat these fractures but it seems more challenging than expected. In literature there is a lack of evidences about the surgical management of distal femoral fractures that is still an important challenge for the orthopaedic surgeon that has to be able to use all the fixation devices available.

    A 15-year-old boy presented with a 35° femoral valgus deformity, leg-length discrepancy, painful retained hardware, and a lateral dislocation of the patella 4 years after undergoing lateral plate fixation of a distal femur fracture. Femoral valgus is a possible complication of lateral plate fixation in up to 30% of pediatric distal femur fractures. With this patient's unusual combination of deformities as an example, we suggest early hardware removal after fracture union to prevent the development of deformity. If plate removal is not chosen, then continued close monitoring of the patient is necessary until skeletal maturity. PMID:27243610

    The causal relationship between chronic use of bisphosphonates and occurrences of atypical femoral fractures has not yet been established. Nonetheless, it is known that their chronic use is more related to fractures with a pattern differing from that of classical osteoporotic fractures. Atypical fractures are still rare events and the benefit from using bisphosphonates remains greater for prevention and treatment of osteoporosis. There are few studies guiding the diagnosis and management of these fractures, thus making it difficult to achieve better results. In this report, we present the case of an elderly patient with an atypical femoral fracture that was managed in accordance with guidance from the American Society for Bone and Mineral Research.

    Intracapsular fracture of femoral neck is treated by anatomical reduction (preferably closed) and cannulated cancellous lag screw fixation. Malunion of these fractures have been described in the coronal plane (coxa valga or coxa vara). We reported a case of young adult patient with displaced intracapsular fracture of femoral neck that had malunited in sagittal plane with callus formation with excellent functional outcome. The radiographs revealed intracapsular fracture of femoral neck right side (Garden type 4 and Pauwel type 3). The patient was operated and closed reduction and internal fixation with three cannulated cancellous screws was performed. The postoperative radiograph revealed a loss of reduction in the lateral view. Due to this technical error, the patient was counselled for revision fixation for which he refused. At 9 months we observed union of the fracture in the displaced position by callus formation. Harris hip score at 2 years was 96 that indicate excellent functional outcome and the radiographs did not reveal any evidence of avascular necrosis of femoral head. We advised revision surgery to our patient as he had increased chances of implant failure and nonunion. However he refused the revision surgery and was continued with the suboptimal reduction. However, the fracture united and that too with callus formation, which is not a described phenomenon in neck of femur fracture. PMID:26777718

    2015-01-01

    Introduction Femoral neck stress fractures are not uncommon. Several causes exist about these fractures. Osteomalacia is one of the most common cause of insufficiency fractures and coxa vara can produce a focal concentration of mechanical stress in the femoral neck and may cause stress fractures. This case study is about the co-existence of these two pathologies in a patient with bilateral femoral neck stress fracture. Presentation of case A 26-year-old woman admitted to our department with a complaint of bilateral groin pain and diagnosed as bilateral coxa vara and osteomalacia. Medical treatment for osteomalacia and staged bilateral Pauwels’ osteotomy was performed. After 2 years of follow-up, good result was obtained. Discussion There are several risk factors for stress fractures and osteomalacia and coxa vara are two of the causes. Osteomalacia results in softening of the bones and coxa vara can produce a focal concentration of stresses in the femoral neck. Conclusion Joint and bone pain without any trauma should be investigated and bone metabolism disorders should be kept in mind. There might be co-existing factors related with stress fractures, and they must be treated simultaneously. PMID:26454499

    Introduction The removal of broken femoral stems has become a major issue in revision surgery, and is a technically difficult and time-consuming procedure. Case presentation We present a case of a fracture of a cementless long femoral stem in a 65-year-old, white Caucasian man. The distal part was removed with a special longitudinal osteotomy through the anterior cortex extending distally for 10cm. It was then followed by a transversal osteotomy 2cm below the tip of the femoral stump to allow enough space for two locking pliers. Simultaneously using a lamina spreader on the distal part, the broken stem was extracted while hammering on two locking pliers. Conclusions We developed a simple and easy technique for the removal of a broken femoral stem that can be applied to all kinds of femoral stems and intramedullary nails regardless of their cross section. We used ordinary surgical instruments and spared the remaining bone stock. PMID:24886067

    We present a case of a 53-year-old woman with subchondral insufficiency fracture (SIF) of the femoral head without history of severe osteoporosis or overexertion. Plain radiographs showed acetabular overcoverage with excessive lateralization of the acetabular rim. A diagnosis of SIF was made by typical MRI findings of SIF. The lesion occurred at the antipodes of the extended rim. Increased mechanical stress over the femoral head due to impingement against the excess bone was suspected as a cause of SIF. The distinct femoral head deformity is consistent with this hypothesis. This is the first report of SIF associated with acetabular overcoverage. PMID:27293935

    Objective: To evaluate the indications, epidemiology, associated lesions, complications and prognosis among children with unstable femoral diaphysis fractures who were treated with titanium elastic intramedullary nails. Method: This was a retrospective analysis on 24 patients aged 5-12 years with unstable femoral diaphysis fractures who underwent surgical treatment with elastic titanium intramedullary nails at the Cajuru University Hospital, Curitiba-PR, between April 2002 and March 2008, with a minimum follow-up of 36 months. The epidemiological data, angular deviations, leg shortening and bone consolidation were evaluated. Results: The medical files of 113 cases operated between April 2002 and March 2008 were reassessed. From these, 24 cases of unstable femoral diaphysis fractures treated with elastic titanium intramedullary nails with retrograde insertion were included in the study. There were two bilateral fractures and two exposed fractures. Seven patients were female and 17 were male, and the mean age was 8.3 years. The following were presented at the end of the study: shortening, varus or valgus displacement, final retrocurvatum or antecurvatum of zero, and absence of delayed consolidation or pseudarthrosis. Conclusions: The elastic titanium intramedullary nails were easily placed and removed. We believe that using elastic titanium intramedullary nails is a good option for fixation of unstable femoral fractures in children. PMID:27047868

    We report the case of a 42-year-old male who suffered a fracture-dislocation of the femoral head. After a closed reduction of the hip, this proceeded to an open reduction with internal fixation of the fractured femoral head, in addition to labral repair and micro-fracture of an articular cartilage defect. After considering the risks to the femoral head blood supply, the trochanteric flip osteotomy was used. This provided ample and safe exposure. At 14 months follow-up, the patient-reported outcome measures are favourable: modified Harris Hip Score (81/100), the non-arthritic hip score (92.5/100) and SF-12 (41/48). PMID:27470013

    Yeni, Yener Nail

    Bone fracture is a major health problem in old population with its complications leading to mortality and morbidity. Therapies mostly involve preventing bone mass loss. Individuals with high bone mass, however, may still suffer fractures suggesting that additional components such as bone microstructure and composition may be responsible for increased fracture risk in the elderly. The relationship of bone constituents with bone fragility, however, is not well-understood. A better understanding of these relationships will help improving therapies by controlling the relevant biological processes. Bone is a composite material with many constituents such as osteons embedded with vascular channels, collagen fibers, mineral crystals, etc. The nature of interfacing between these constituents makes bone a more complex material. Bone also has a structure that adapts itself, both internally and externally, to better fit its needs. This suggested that, unlike man-made materials, a relationship between material properties and structural properties may exist. Because bone has some similarities with engineering composite materials and also experiences microcracks, a fracture mechanics approach would be more appropriate for investigating its fragility. Choosing mode I and mode II fracture toughness (Gsb{Ic} and Gnsb{IIc}, respectively) as indicators of bone fragility, their relationship with bone microstructure (porosity, osteon morphology, mineral crystal imperfection and microdamage), composition (density, mineral, organic, water and collagen content) and macrostructure (thickness, diameter and moment of inertia of the shaft and angle between the femoral neck and femoral shaft from different views) was investigated. Use of x-ray radiogrammetry for detecting the latter was tested. Differences among the femoral shaft, femoral neck and the tibia were investigated for an age range of 22-94 years. In general, fracture toughness increased with increasing bone quantity. However, the

    Geriatric hip fractures are a challenging clinical problem throughout the world. Hip fracture services have been shown to shorten time to surgery, decrease the cost of admissions, and improve the outcomes. We instituted a geriatric hip fracture program for comanagement of these injuries by orthopedic and internal medicine teams at our hospital in India. From January 2010 till December 2011, 119 patients with a femoral neck fracture were treated with cemented modular hemiarthroplasty under this program using a cost-effective Indian implant. The cohort included 63 males and 56 females with a mean age of 70.7 years (range 55-98 years). Hypertension (n = 42) and diabetes mellitus (n = 29) were the most common comorbidities. The follow-up period ranged from 12 to 37 months with an average of 24 months. The surgery was performed within 24 hours of admission in 60.5% (n = 72) patients. The use of antiplatelet drugs was the most common reason for delay of surgery. The mean length of hospital stay was 10.4 days (range 3-24 days) with 77% (n = 92) of patients discharged within 1 week of admission. On follow-up, good to excellent Harris hip scores were seen in 88% of patients with 76% of patients returning to the preinjury ambulatory status. The mortality rate was 6% at 6 months follow-up and 10.9% at 2 years. Our study shows that a hip fracture program can be instituted in India. The program helped us in achieving the goal of early surgery, mobilization, and discharge from hospital with decreased mortality. PMID:26246953

    Fibrous dysplasia (FD) is a rare bone disorder in which normal medullary bone is replaced by fibro-osseous tissue. It typically presents in childhood with pain, skeletal deformities, gait abnormalities and occasionally, fatigue fractures. The management of FD remains a challenge. Surgical procedures have been developed to provide symptom relief, correct skeletal deformity and offer mechanical support in cases at risk of fracture. However, there is a paucity of data on the management of acute femoral neck fractures in the adult population with FD. We report the case of a 23-year-old man with a shepherd's crook deformity secondary to FD, who sustained an intra-capsular femoral neck fracture whilst playing football. The patient initially underwent closed reduction and internal fixation with cannulated screws. However, during the procedure, a guide wire broke whilst inside the femoral head. The patient was referred to the senior author, who undertook a second operation to remove the metalwork and correct the varus deformity using a closing-wedge femoral osteotomy, whilst achieving osteosynthesis at the fracture site. At 1-year follow-up, the patient is pain-free and demonstrates a full range of movement. These cases can be technically demanding and carry a greater risk of complication. It is important that preoperative planning is undertaken and surgery performed by individuals with experience in managing FD and complex femoral neck fractures. Correction of the skeletal deformity whilst fixing the fracture will help restore the mechanical axis and reduce the risk of a recurrent fracture. PMID:24036944

    Despite the multitude of studies published on atypical femoral fractures (AFFs), a profile for patients at risk does not exist. This study aimed first at estimating AFF incidence over a 19-month-period in Quebec City using the ASBMR Task force criteria to define AFF. The medical records of patients hospitalized for hip or femoral fracture between June 1, 2009, and December 31, 2010, were reviewed. Thirty-six cases of atypical fractures were identified during the 19-month period, representing an AFF incidence of 7.0 (range, 4.7 to 9.3) cases per 100,000 person-years. In the second part of the study, data regarding the characteristics suspected of increasing the risks of AFF were collected from medical and pharmacological records, proximal femur radiographs, and patient interviews. The data regarding each patient with an AFF during years 2008-2011 were compared to two controls with a hip or femoral fragility fracture or a traumatic fracture, paired for age and sex. Twenty patients with AFF were added to the 36 patients with AFF selected in the first part, thereby 56 patients with AFF were investigated. The association between the occurrence of AFF and bisphosphonates (BPs) use was proven statistically significant in multivariate analysis, odds ratio (OR) = 10.39 (95% CI, 2.22 to 48.58; p = 0.0029). Compared to controls, patients with AFF had excessive femoral offset (43.1 mm versus 38.3 mm, p = 0.0007), proximal femoral neck angle in varus (128.9 degrees versus 134.0 degrees, p < 0.0001), and had greater proximal cortical thickness. This retrospective study confirms the low incidence of AFF, confirms its significant association with exposure to BPs, and reveals the possible contribution of proximal femoral geometry in AFF occurrence.

    Introduction The avascular necrosis of the femoral head represents the death of bone tissue due to the lack of blood supply. The disease has a progressive evolution and left untreated leads to femoral head collapse and severe arthritis. Case presentation We present a case of a pertrochanteric fracture which has been successfully operated with a dynamic interlocking trochanteric gamma nail on the right hip. At 2 years after surgery the patient developed an incipient avascular necrosis of the femoral head. Despite the good positioning of the implant, we considered that the source of the pain was an intolerance of the implant, and thus we removed it. After implant removal, the patient was kept under observation and conservative treatment, to prevent further damage to the right hip and allow the healing to occur. At 6 months after the gamma nail was removed the X-rays revealed advanced avascular necrosis of the femoral head and secondary osteoarthritis on the right hip. The patient underwent surgery with an uncemented total hip arthroplasty. Discussion There are a few discussions regarding the avascular necrosis of the femoral head. These discussions may include the predisposing risk factors, the treatment of choice and the postoperative complications. Conclusion The avascular necrosis of the femoral head is a complication of pertrochanteric fractures that can not be foreseen or avoided. The optimal treatment in these cases is uncemented total hip arthroplasty. PMID:26900462

    Peri-prosthetic femoral neck fracture after femoral head resurfacing can be either patient-related or surgical technique-related. The study aimed to develop a patient-specific finite element modelling technique that can reliably predict an optimal implant position and give minimal strain in the peri-prosthetic bone tissue, thereby reducing the risk of peri-prosthetic femoral neck fracture. The subject-specific finite element modelling was integrated with optimization techniques including design of experiments to best possibly position the implant for achieving minimal strain for femoral head resurfacing. Sample space was defined by varying the floating point to find the extremes at which the cylindrical reaming operation actually cuts into the femoral neck causing a notch during hip resurfacing surgery. The study showed that the location of the maximum strain, for all non-notching positions, was on the superior femoral neck, in the peri-prosthetic bone tissue. It demonstrated that varus positioning resulted in a higher strain, while valgus positioning reduced the strain, and further that neutral version had a lower strain. PMID:27098752

    The treatment of an above knee amputee who has sustained a fracture of the femoral neck is a chal- lenging situation for both the orthopedic surgeon and the rehabilitation team. These fractures may be managed acutely either by reduction and internal fixation or by endoprosthetic replacement based on the same criteria as in any other patient with otherwise intact limbs.We present a neglected case treated successfully with valgus osteotomy. We conclude that these fractures should be treated with the same urgency and expertise as similar fractures in non-amputees as long-term survival and good quality of life can be expected.

    Summary Fragility fractures of the femur are one of the major causes of morbidity and mortality worldwide. The incidence of new contralateral hip fractures in elderly osteoporotic patients ranges from 7 to 12% within 2 years after the first fracture. Secondary prevention can be divided in: pharmacological therapy based on the prescription of anti-osteoporotic drugs with different mechanism of action and non-pharmacological therapy which is based on modification of environmental risk factors, on a healthy diet with daily supplements of calcium and vitamin D and calcium and on the use of hip protectors. Recently a new form of prevention is becoming achievable: surgical prevention; the rationale of surgical reinforcement is the need to increase the resistance of the femoral neck to the compression and distraction forces acting on it. In this paper we analyse all the experimental and “on the market” device available for the surgical prevention of femoral neck fracture. PMID:27252744

    A femoral-sided avulsion fracture of the anterior cruciate ligament (ACL) is a rare and challenging condition. Most reported cases have occurred in childhood or adolescence. Many techniques of ACL repair have been reported, and in recent years, techniques in arthroscopic surgery have been developed and have become ever more popular with orthopaedic surgeons. We created a technique of arthroscopic ACL repair with suture anchor fixation for a femoral-sided ACL avulsion fracture. This technique saves the natural ACL stump. It is available for cases in which creation of a tibial tunnel is not allowed. Moreover, it does not require a skin incision for fixation on the far femoral cortex and, therefore, does not require a second operation to remove the fixation device. The arthroscopic technique also has a good cosmetic outcome. PMID:26258035

    Femoral neck stress fracture (FNSF) is well documented in the orthopedic literature and is generally associated with strenuous activities such as long-distance running and military training. The diagnostic yield of magnetic resonance imaging (MRI) for FNSF was reported to be 100 %, and early MRI is recommended when this fracture is suspected. We encountered a 16-year-old male long-distance runner with FNSF in whom the left femoral neck showed no signal changes on MRI although an effusion was detected in the left hip joint. One month later, roentgenograms revealed periosteal callus and oblique consolidation of the left femoral neck, confirming the diagnosis of compression FNSF. Because FNSF with a normal bone marrow signal on MRI is very rare, this patient is presented here. PMID:27020451

    We describe a case of oncogenic osteomalacia in an adult male who presented with low back pain and bilateral hip pain. Extensive investigations had failed to find a cause. A plain pelvic radiograph showed Looser's zones in both femoral necks. MRI confirmed the presence of insufficiency fractures bilaterally in the femoral head and neck. Biochemical investigations confirmed osteomalacia which was unresponsive to treatment with vitamin D and calcium. A persistently low serum phosphate level suggested a diagnosis of hypophosphataemic osteomalacia. The level of fibroblast growth factor-23 was highly raised, indicating the cause as oncogenic osteomalacia. This was confirmed on positron-emission tomography, MRI and excision of a benign fibrous histiocytoma following a rapid recovery. The diagnosis of oncogenic osteomalacia may be delayed due to the non-specific presenting symptoms. Subchondral insufficiency fractures of the femoral head may be missed unless specifically looked for. PMID:20595128

    We report the case of a 42-year-old male who suffered a fracture–dislocation of the femoral head. After a closed reduction of the hip, this proceeded to an open reduction with internal fixation of the fractured femoral head, in addition to labral repair and micro-fracture of an articular cartilage defect. After considering the risks to the femoral head blood supply, the trochanteric flip osteotomy was used. This provided ample and safe exposure. At 14 months follow-up, the patient-reported outcome measures are favourable: modified Harris Hip Score (81/100), the non-arthritic hip score (92.5/100) and SF-12 (41/48). PMID:27470013

    Background Stable trochanteric femur fractures can be treated successfully with conventional implants such as sliding hip screw, cephalomedullary nails, angular blade plates. However comminuted and unstable inter or subtrochanteric fractures with or without osteoporosis are challenging & prone to complications. The PF-LCP is a new implant that allows angular stability by creating fixed angle block for treatment of complex, comminuted proximal femoral fractures. Method We reviewed 30 patients with unstable inter or subtrochanteric fractures, which were stabilized with PF-LCP. Mean age of patient was 65 years, and average operative time was 80 min. Patients were followed up for a period of 3 years (June 2010–June 2013). Patients were examined regularly at 3 weekly interval for signs of union (radiological & clinical), varus collapse (neck-shaft angle), limb shortening, and hardware failure. Result All patients showed signs of union at an average of 9 weeks (8–10 weeks), with minimum varus collapse (<10°), & no limb shortening and hardware failure. Results were analysed using IOWA (Larson) hip scoring. Average IOWA hip score was 77.5. Conclusion PF-LCP represents a feasible alternative for treatment of unstable inter- or subtrochanteric fractures. PMID:25983487

    Purpose People with dementia have poor mobility and discharge outcomes following hip fractures. The purpose of this study was to evaluate the clinical and radiological results of internal fixation of undisplaced femur neck fractures (Garden types 1 and 2) by proximal femoral nail antirotation (PFNA) in dementia patients. Materials and Methods We studied retrospectively 19 patients with undisplaced femur neck fracture. All patients were over 70 years of age, walked independently with a cane or crutches and suffered moderate-to-severe dementia. Patients were treated with PFNA and followed-up for more than 2 years. Revision, loss of fixation, complications, and walking ability outcomes were measured. Results In walking-ability evaluation, patients showed an average decrease of just 0.2 points at the final follow-up. Walking ability was evaluated from before injury to 4 weeks after surgery and decreased by less than 0.5 points. Radiological bone union was achieved in 17 cases; the average time to bone union was 4.14 months (range, 2.5-7 months). Complications included non-union in two cases and femoral head avascular necrosis in one case of non-union. Conclusion We found that for patients with osteoporotic bone tissues in their femoral heads or patients (e.g., those suffering dementia) for whom cooperating with medical workers for postoperative walking control or rehabilitation exercises is difficult, implanting a mechanically stable spiral blade for fixation of femoral neck fractures could facilitate walking after surgery.

    Guide wire plays an important role in the fixation of femoral neck fracture with dynamic hip screw (DHS). Breakage of a guide wire during operation is a very rare condition. We met such a dilemma in DHS fixation of a 54-year-old male patient who sustained Garden type IV fracture of the right femoral neck. The distal end of the guide wire broke and was entrapped in the fractured femoral neck. We tried to get the broken part out by a cannulated drill. Reaming was started with the cannulated drill slowly rotating around the guide K-wire until the reamer fully contained the target under fluoroscope. A bone curette was used to get the broken wire out but failed, so we had to use the cannuated drill to dredge this bone tunnel. Finally the broken wire end was taken out, mixed with blood and bone fragments. Through the existing drilling channel, DHS fixation was easily finished. The patient had an uneventful recovery without avascular necrosis of femoral head or non-union of the fracture at one year's follow-up. A few methods can be adopted to deal with the broken guide wire. The way used in our case is less invasive but technically challenging. When the guide wire is properly positioned, this method is very practical and useful. PMID:23910678

    Purpose This study was conducted to evaluate the results of internal fixation for stable femoral neck fractures occurring in patients over 65 years old. Materials and Methods Between 2008 and 2014, we evaluated 25 patients over 65 years old with Garden type 1 and 2 femoral neck fractures that were treated with internal fixation after a minimum follow up of 1 year. There were 5 males and 20 females and the average age was 72.3 years (range, 65-84 years) at the time of surgery. Fracture site union, horizontal shortening and complications were evaluated as radiographic parameters and change of walking ability (as measured using Koval walking ability score) was investigated as a clinical parameter. Results Union of fracture site was achieved in 24 out of the 25 cases (96.0%). The average length of horizontal shortening was 6.5 mm (range, 0.2-19.7 mm). At final follow up, 3 cases experienced complications: nonunion (n=1), avascular necrosis (n=1), and subtrochanteric fracture after minor trauma (n=1). Walking ability decreased an average of 1 step at the final follow up. Conclusion Internal fixation for stable femoral neck fractures occurring in patients over 65 years showed satisfactory union rates. However, care should be taken with this technique given the possibility of decreased walking ability resulting from horizontal shortening.

    Purpose This study aims to determine the correlation between the fracture patterns and the complications in patients with femoral neck fracture treated with internal fixation. Materials and Methods The study comprises 45 patients with femoral neck fracture treated with multiple screws or compression hip screw between May 2008 and April 2012. The mean age was 48 years at the time of the surgery and the mean duration from initial injury to surgery was 20 hours. The fracture patterns were identified according to the anatomical location, the Garden classification and the Pauwels classification. The occurrence of nonunion and avascular necrosis were reviewed with clinical results including Harris hip score and Lunceford hip function test. The correlation between the fracture pattern and occurrence of complications were analyzed. Results Fracture site union was achieved in 40 hips with the average union time of 17 weeks. Five nonunions occurred which showed high likelihood to occur in subcapital type, displaced (Garden stage III or IV) and Pauwels type III fractures (P<0.05). Avascular necrosis was developed in 10 hips which was mostly in subcapital type and Pauwels type III fracture but no statistical significance was found (P>0.05). The mean Harris hip score was 91 points, and Lunceford functional results were excellent in 15 hips, good in 24, fair in 4 and poor in 2. Conclusion There was high risk of nonunion in subcapital type fracture, displaced fracture (Garden stage III and IV) and vertically oriented fracture (Pauwels type III). Careful attention is needed in these fracture types.

    Introduction Delayed union and non-union of displaced femoral neck fractures remains a difficult clinical problem for orthopaedic surgeons. In the physiologically young patient, every effort should be made to preserve the native hip joint. We present two cases of ununited femoral neck fractures in young adults who were successfully treated with low-intensity pulsed ultrasound (LIPUS) and showed satisfactory results. Presentation of case 1 A 41-year-old woman was involved in a motor vehicle crash and was diagnosed with displaced femoral neck fracture. Eleven months after internal fixation, a computed tomography (CT) scan revealed the presence of non-union of the femoral neck. LIPUS treatment was therefore initiated. After eight months, the fracture was completely consolidated. Presentation of case 2 A 39-year-old man was involved in a cycling accident and was diagnosed with displaced femoral neck fracture. Thirteen weeks after internal fixation, a CT scan revealed delayed union of the femoral neck. LIPUS treatment was therefore initiated. After six months, the fracture was completely consolidated. Conclusion We suggest use of LIPUS as a possible treatment approach for delayed union and non-union of displaced femoral neck fractures in young patients before considering further surgical intervention.

    2015-01-01

    Purpose We aimed to quantify proximal femoral shortening after operation with compression hip screws for intertrochanteric fracture in patients under the age of 60 years. Materials and Methods We followed 37 consecutive patients with intertrochanteric fractures treated with compression hip screws from March 2005 to February 2014. We designated the aspect of the fracture, a defect of the postero-medial wall, a defect of the lateral wall, and the degree of reduction as four potentially important factors we assumed would strongly affect proximal femoral shortening. We quantified proximal femoral shortening and compared the effects of above factors. We divided femoral shortening into two plane vectors; femoral offset in the horizontal plane and leg length discrepancy in the vertical plane. We measured shortening separately during two periods: during operation and after weight bearing (called dynamic compression). Results After bone union, the average femoral offset shortening was 5.45 mm. Patient groups with anatomic reduction and intact postero-medial wall showed lower femoral offset shortening than the respective opposite groups. As to functional score using modified Harris hip score, low femoral offset shortening group showed more 2.35 scores than high groups. None of the factors significantly affected leg length shortening. Conclusion We found that a stable medial buttress is involved in lower femoral offset shortening. Thus, surgeons need to attempt to recover the defect of the medial wall and to reduce anatomically when operating intertrochanteric fractures with compression hip screws.

    Patient specific quantitative CT (QCT) imaging data together with the finite element (FE) method may provide an accurate prediction of a patient's femoral strength and fracture risk. Although numerous FE models investigating femoral fracture strength have been published, there is little consent on the effect of boundary conditions, dynamic loading and hydraulic strengthening due to intra-medullary pressure on the predicted fracture strength. We developed a QCT-derived FE model of a proximal femur that included node-specific modulus assigned based on the local bone density. The effect of three commonly used boundary conditions published in literature were investigated by comparing the resulting strain field due to an applied fracture load. The models were also augmented with viscoelastic material properties and subject to a realistic impact load profile to determine the effect of dynamic loads on the strain field. Finally, the effect of hydraulic strengthening was investigated by including node specific permeability and performing a coupled pore diffusion and stress analysis of the FE model. Results showed that all boundary conditions yield the same strain field patterns, but peak strains were 22% lower and fracture load was 18% higher when loaded at the greater trochanter than when loaded at the femoral head. Comparison of the dynamic models showed that material viscoelasticity was important, but inertial effects (vibration and shock) were not. Finally, pore pressure changes did not cause significant hydraulic strengthening of bone under fall impact loading. PMID:23906770

    Simultaneous bilateral femoral neck fracture is rare injury. Cases with this type of fracture have been reported in the literature since the 1950s, following the introduction of electroconvulsive therapy which generates violent hip muscle contractions. In young patients' simultaneous bilateral femoral neck fracture results from high energy trauma (car accident or fall from height) in a normal bone. Pathological changes in bone structure occurring in chronic kidney disease, vitamin D deficiency, osteomalacia, osteoporosis, metabolic imbalances and administration of corticosteroids explain the occurrence of this particular type of fracture following low-energy trauma. We present the case of a 90-year-old female patient who suffered a simple fall from her own height resulting in a Garden IV bilateral femoral neck fracture. Our therapeutic option in this patient was bilateral uncemented bipolar hemiarthroplasty in a single session using a single tray of sterile surgical instruments and two sterile drapes. Postoperative outcome was very good, allowing the initiation of functional recovery on the first postoperative day. Uncemented hemiarthroplasty proved to be a good choice in such a patient in the associated diseases may trigger the risk of cardiovascular disturbances specific to bone cement implantation syndrome.

    Optimal management of periprosthetic femoral fractures (PFF) around a well fixed prosthesis (Vancouver B1) remains controversial as adequate fixation needs to be achieved without compromising the stability of the prosthesis. The aim of this study was to highlight the effect of bone quality i.e. canal thickness ratio (CTR), and fracture topography i.e. fracture angle and its position in relation to the stem, on the biomechanics of a locking plate for a Vancouver B1 fracture. A previously corroborated simplified finite element model of a femur with a cemented total hip replacement stem was used in this study. Canal thickness ratio (CTR) and fracture topography were altered in several models and the effect of these variations on the von Mises stress on the locking plate as well as the fracture displacement was studied. Increasing the CTR led to reduction of the von Mises stress on the locking plate as well as the fracture movement. In respect to the fracture angle with the medial cortex, it was shown that acute angles resulted in lower von Mises stress on the plate as opposed to obtuse angles. Furthermore, acute fracture angles resulted in lower fracture displacement compared to the other fractures considered here. Fractures around the tip of the stem had the same biomechanical effect on the locking plate. However, fractures more distal to the stem led to subsequent increase of stress, strain, and fracture displacement. Results highlight that in good bone quality and acute fracture angles, single locking plate fixation is perhaps an appropriate management method. On the contrary, for poor bone quality and obtuse fracture angles alternative management methods might be required as the fixation might be under higher risk of failure. Clinical studies for the management of PFF are required to further support our findings. PMID:25467710

    In Fanconi syndrome, hypophosphatemic osteomalacia is caused by proximal renal tubule dysfunction which leads to impaired reabsorption of amino acids, glucose, urate, and phosphate. We present a rare case of a 43-year-old Korean male who was found to have insufficiency stress fracture of the femoral neck secondary to osteomalacia due to Fanconi syndrome. He had been receiving low-dose adefovir dipivoxil (ADV, 10 mg/day) for the treatment of chronic hepatitis B virus infection for 7 years and he subsequently developed severe hypophosphatemia and proximal renal tubule dysfunction. The incomplete femoral neck fracture was fixed with multiple cannulated screws to prevent further displacement of the initial fracture. After cessation of ADV and correction of hypophosphatemia with oral phosphorus supplementation, the patient's clinical symptoms, such as bone pain, muscle weakness, and laboratory findings improved.

    Bilateral non traumatic femoral neck fatigue fracture is a rare condition usually occurring secondary to medical conditions such as pregnancy, pelvic irradiation, corticosteroid exposure, chronic renal failure and osteomalacia. In this report, we present three young female patients with bilateral femoral neck fracture secondary to osteomalacia. The underlying cause of osteomalacia was Celiac disease in all patients. The patients were treated with closed reduction and internal fixation with cannulated lag screws. They were free of pain and full weight bearing was achieved at three months. There were no complications, avascular necrosis and nonunion during the follow up period. In patients with bone pain, non traumatic fractures and muscle weakness, osteomalacia should be kept in mind and proper diagnostic work-up should be performed to identify the underlying cause of osteomalacia such as celiac disease.

    Introduction: Fracture of the femoral stem following hip arthroplasty has become very rare since the developments in modern prosthetic designs. Prevention by identifying the risk factors is the best way to overcome these complex problems, as treatment is difficult. Case Report: Femoral component fracture after cemented hemiarthroplasty in a physically active 64-year-old, male patient is reported in this present article. Conclusion: The present case emphasizes the importance of preserving the joint after hip fracture and avoidance of using mono block prosthesis in younger patients. If the patient is physically active, he/she should be advised to limit her/his daily activities to moderate intensity after hemiarthroplasty surgery. PMID:27299090

    Fatigue fracture of a femoral component in total hip arthroplasty is a rare occurrence but well documented in the literature. It is understood that proximal loosing of a femoral stem with a well fixed stem distally will result in cantilever bending and eventual fatigue fracture of the stem. Other factors which may potentiate a fatigue fracture are material design, implant positioning, and patient characteristics. More recently, laser etching on the femoral neck of an implant has resulted in fatigue fracture. We report a case of a fatigue fracture at the neck–shoulder junction in a well fixed, uncemented, femoral component due to laser etching in the region of high tensile stress. PMID:24403758

    A red-tailed hawk (Buteo jamaicensis) and a Canada goose (Branta canadensis) were evaluated for unilateral pelvic limb lameness. Physical examination findings and results of diagnostic imaging revealed femoral neck fractures in both birds. Both birds were treated with a femoral head and neck excision arthroplasty. The affected legs were not immobilized, and the birds were encouraged to use the legs immediately after surgery to encourage formation of a pseudoarthrosis. Within 2 weeks, both birds were using the affected limb well enough to be either successfully released or transferred to a wildlife rehabilitation facility. Femoral head and neck excision arthroplasty without immobilization of the limb is recommended for managing avian femoral neck fractures, especially in free-ranging species in which a rapid and complete or near complete return to function is vital for survival in the wild.

    We describe the case of a 70-year old male with total occlusion of the left superficial femoral artery (SFA) treated with percutaneous implantation of a self-expanding nitinol stent. The patient's course post-stent implantation was complicated by the development of stent fracture with SFA perforation and a large, compressive intramuscular hematoma with deep venous thrombosis (DVT). The patient returned to the catheterization laboratory where the fracture and perforation were successfully treated by the deployment of another stent across the fracture site. The DVT was initially treated with an inferior vena cava filter until anticoagulation could safely be instituted. PMID:18762680

    Klippel-Trenaunay syndrome (KTS) is a rare complex malformation characterized by the clinical triad of capillary malformations, soft tissue and bone hypertrophy, and venous/lymphatic malformation. Fractures of long bones in such cases are challenging to treat. A 12-year-old female with this syndrome presented with femoral shaft fracture of right thigh. She was initially kept on skeletal traction for two weeks and then she underwent closed reduction and immobilization with external fixator with uneventful intraoperative and postoperative period. Fracture united at four and half months. PMID:26885423

    Bisphosphonates are the most common medication used to treat patients with documented osteoporosis. Recently, reports have associated long-term bisphosphonate use with low-energy femur fractures. While no definitive mechanism has been associated, bisphosphonate use has been strongly implicated. This article presents the case of a 65-year-old woman with a 2-year history of ibandronate use presenting with simultaneous low-energy femoral shaft fractures. The patient reported prodromal bilateral thigh pain and was seen by a spine surgeon. A review of the literature implicates long-term ibandronate use in low-energy femur fractures. With most of the basic science studies demonstrating suppressed bone turnover after 5 years of treatment with alendronate, the significance of the present case also lies in the relatively short duration of time the patient was on ibandronate before suffering the bilateral femoral shaft fractures. Possible pathophysiology for the fractures includes suppressed bone turnover that may allow microcracks to propagate in cortical bone, which can weaken the bone and possibly predispose it to fractures. Patients who have been on bisphosphonates long term should be questioned about thigh pain and have radiographs of their femurs obtained if pain exists. Furthermore, if a patient presents with a single subtrochanteric or diaphyseal low-energy femur fracture after long-term bisphosphonate use, a radiograph of the contralateral femur should be obtained to assess for a cortical stress reaction.

    2013-01-01

    Purpose Locked plating (LP) of distal femoral fractures has become very popular. Despite technique suggestions from anecdotal and some early reports, knowledge about risk factors for failure, nonunion (NU), and revision is limited. The purpose of this study was to analyze the complications and clinical outcomes of LP treatment for distal femoral fractures. Materials and methods From two trauma centers, 243 consecutive surgically treated distal femoral fractures (AO/OTA 33) were retrospectively identified. Of these, 111 fractures in 106 patients (53.8% female) underwent locked plate fixation. They had an average age of 54 years (range 18 to 95 years): 34.2% were obese, 18.9% were smokers, and 18.9% were diabetic. Open fractures were present in 40.5% with 79.5% Gustilo type III. Fixation constructs for plate length, working length, and screw concentration were delineated. Nonunion and/or infection, and implant failure were used as outcome complication variables. Outcome was based on surgical method and addressed according to Pritchett for reduction, range of motion, and pain. Results Eighty-three (74.8%) of the fractures healed after the index procedure. Twenty (18.0%) of the patients developed a NU. Four of 20 (20%) resulted in a recalcitrant NU. Length of comminution did not correlate to NU (p = 0.180). Closed injuries had a higher tendency to heal after the index procedure than open injuries (p = 0.057). Closed and minimally open (Gustilo/Anderson types I and II) fractures healed at a significantly higher rate after the index procedure compared to type III open fractures (80.0% versus 61.3%, p = 0.041). Eleven fractures (9.9%) developed hardware failure. Fewer nonunions were found in the submuscular group (10.7%) compared to open reduction (32.0%) (p = 0.023). Fractures above total knee arthroplasties had a significantly greater rate of failed hardware (p = 0.040) and worse clinical outcome according to Pritchett (p = 0.040). Loss of

    Background Intertrochanteric fractures are one of the most common fractures encountered in our practice. Most of them need operative intervention and union is achieved. As per the literature dynamic hip screw (DHS) is the gold standard for the treatment of these fractures, however problem arises with maintenance of neck shaft angle and proper reduction in unstable intertrochanteric fractures. The situation gets more complex when “cut out” of femoral head screw occurs either alone or in combination with varus collapse when they are treated with DHS. Here we are giving results of unstable intertrochanteric fractures treated with Proximal Femoral Locked Compression Plate (PFLCP) as compared with similar patients treated with Dynamic Hip Screw (DHS). Materials and Methods The study included a total of 27 patients (17 males, 10 females) with unstable intertrochanteric fractures who were subjected to PFLCP treatment from March 2011 to November 2012 in one group. Another was a similar group of 35 patients treated with DHS from March 2008 to February 2010. Results of group 1 were compared with group 2. Detailed clinical conditions of all patients, duration of surgery, blood loss, length of incision and duration of image intensifier use were recorded. Patients were revisited at 6 weeks, 3 months, 6 months and 1 year after operation. Results were evaluated clinically by Harris hip Score and radiologically for fracture union. Progress of union and complications (limb shortening, varus collapse, cut out of femoral head screw and medialization of distal fragment) were recorded. Results Among 27 patients treated with PFLCP, one patient expired 6 week postoperatively and one patient lost to follow up, so 25 patients were evaluated for final outcome of which 23 (92%) showed union at follow up of 12 months. One patient developed bending of proximal screws and three developed varus collapse. Among the group treated with DHS, eight patients developed varus collapse, seven

    Multidisciplinary approach for proximal femoral fracture was organized in the hospital. Inter and intra division obstacles were discussed. After general consensus of the team was obtained, manuals and guidelines of the each division were prepared. In addition to this, the electrical chart specific for the proximal femoral fracture was made which enables to eliminate in-hospital reference letters. As the results, all patients were examined by internal medicine doctors at the time of admission. Average interval from the time of admission to surgery became 1.3 days. Closer relationship with psychiatrist made early detection and treatment of delirium possible. After changing the system to check the antiosteoporosis medication at the time of discharge by the ward pharmacist dramatically increased the prescription rate form 39 percent to 95 percent.

    Background Femoral shaft stress fractures in athletes are not common but pose a great diagnostic challenge to clinicians. Because of few clinical signs, diagnosis and treatment are often delayed. Furthermore, if not treated correctly, these fractures are well known for complications and difficulties. Objective To develop a well structured and reproducible treatment algorithm for athletes with femoral shaft stress fractures. Methods The proposed algorithm is carried out in four phases, each lasting three weeks, and the move to the next phase is based on the result of the tests carried out at the end of the previous phase. Over nine years, we treated seven top level athletes, aged 17–21. In all athletes, diagnosis was based on physical examination, plain radiographs, and bone scan. Results As a result of the treatment method, all the athletes were fully engaged in athletic activity 12–18 weeks after the beginning of treatment. After completion of the treatment, the athletes were followed up for 48–96 months. During the follow up, there was no recurrence of discomfort or pain, and all the athletes eventually returned to competition level. Conclusion These results and data available from the literature suggest that the algorithm is the optimal treatment protocol for femoral shaft stress fractures in athletes, avoiding the common complications and difficulties.

    Introduction Acute gastrointestinal stress ulceration is a common and serious complication of trauma. Prophylactic proton pump inhibitors (PPIs) or histamine receptor antagonists have been used in poly-trauma, burns and head and spinal injuries, as well as on intensive care units, for the prevention of acute gastric stress ulcers. Methods We prospectively studied the use of prophylactic PPIs in with femoral neck fracture patients, gathering data on all acute gastric ulcer complications, including coffee-ground vomiting, malena and haematemesis. We then implemented a treatment protocol in which all patients were given prophylactic PPIs, again prospectively collecting all data. Results Five hundred and fifteen patients were included. Prior to prophylactic PPI, 15% of patients developed gastric stress ulcer complications, with 3% requiring acute intervention with oesophagogastroduodenoscopy (OGD), 5% requiring transfusions and 4% experiencing surgical delays. All patients had delayed discharges. Following PPI implementation, no patients developed gastric stress ulcer complications. Conclusions Femoral neck fracture patients create a substantial workload for orthopaedic units. The increasingly elderly population often have comorbidities, and concomitantly use medications with gastrointestinal side effects. This, combined with the stress of a fracture and preoperative starvation periods increases the risk of gastric ulcers. Here, the use of prophylactic PPIs statistically reduced the incidence of gastric stress ulcers in patients with femoral neck fractures, resulting in fewer surgical delays, reduced length of hospital stay and reduced stress ulcer-related mortality.

    Chen, Antonia F.

    2015-01-01

    Management of periprosthetic fractures around the femoral stem after total hip arthroplasty (THA) represents a significant challenge and optimal treatment remains controversial. The most common treatment paradigm involves treating fractures around a well-fixed stem with osteosynthesis, whereas fractures around a loose stem require revision arthroplasty and those with poor bone require augmentation with bone graft. Paradoxically, the literature reports a higher rate of failure for osteosynthesis around prostheses considered to be well-fixed. Such a high rate of poor outcomes may result not only from difficult fracture fixation and compromised biologic healing, but also from unrecognized peri-implant pathology. Therefore, proper preoperative and intraoperative evaluation is key, and a subset of patients may benefit from alternative management. We review the appropriate methods for evaluation and treatment of Vancouver type B fractures with particular emphasis on avoiding missteps that can lead to failure. PMID:26539451

    Fat embolism syndrome is usually associated with surgery for large bone fractures. Symptoms usually occur within 36 hours of hospitalization after traumatic injury. We present a case with fat embolism syndrome due to femur fracture. Prompt supportive treatment of the patient’s respiratory system and additional pharmaceutical treatment provided the positive clinical outcome. There is no specific therapy for fat embolism syndrome; prevention, early diagnosis, and adequate symptomatic treatment are very important. Most of the studies in the last 20 years have shown that the incidence of fat embolism syndrome is reduced by early stabilization of the fractures and the risk is even further decreased with surgical correction rather than conservative management.

    Purpose We investigated the incidence and time of dislocation and other factors associated with dislocation of bipolar hemiarthroplasty related to the treatment of femoral neck fracture in old age patients. Materials and Methods Between January 2002 and April 2014, 498 femoral neck fractures (467 patients) were treated with bipolar hemiarthroplasty and included in this study. All surgeries were performed using the postero-lateral approach. The incidence of dislocation was investigated. A comparative analysis between a control group and dislocation group was performed with respect to patient factors including age, gender, body mass index, comorbidities, the ASA (American Society of Anesthesiologists) score, mental status and center-edge angle, and surgical factors including type of femoral stem, leg length discrepancy, femoral offset and method of short external rotator (SER) reconstruction. Results The incidence of dislocation was 3.8%, and the dislocation occurred on average 2.2 months (range, 0.6-6.5 months) after operation. No difference in patient-related factors was observed between the two groups. However, a smaller center edge (CE) angle was observed in the dislocation group (42.1°±3.2° vs. 46.9°±5.4°, P<0.001), and significantly lower incidence of dislocation was observed in tendon to bone repair group (0.7% vs 7.8%, P<0.001). Conclusion SERs should be repaired using the tendon-to-bone repair method to reduce dislocation rate in elderly patients who undergo bipolar hemiarthroplasty using the postero-lateral approach due to femoral neck fracture. In addition, patients with smaller CE angle should be carefully monitored due to high incidence of dislocation. PMID:27536652

    The reliability of proximal femoral fracture classifications using 3DCT was evaluated, and a comprehensive “area classification” was developed. Eleven orthopedists (5–26 years from graduation) classified 27 proximal femoral fractures at one hospital from June 2013 to July 2014 based on preoperative images. Various classifications were compared to “area classification.” In “area classification,” the proximal femur is divided into 4 areas with 3 boundary lines: Line-1 is the center of the neck, Line-2 is the border between the neck and the trochanteric zone, and Line-3 links the inferior borders of the greater and lesser trochanters. A fracture only in the first area was classified as a pure first area fracture; one in the first and second area was classified as a 1-2 type fracture. In the same way, fractures were classified as pure 2, 3-4, 1-2-3, and so on. “Area classification” reliability was highest when orthopedists with varying experience classified proximal femoral fractures using 3DCT. Other classifications cannot classify proximal femoral fractures if they exceed each classification's particular zones. However, fractures that exceed the target zones are “dangerous” fractures. “Area classification” can classify such fractures, and it is therefore useful for selecting osteosynthesis methods.

    Objective: to evaluate epidemiological and radiological characteristics of the femoral shaft fractures, surgically treated from 1990 to 2005 at Hospital de Acidentados – Clínica Santa Isabel – in Goiânia, Goiás, aiming to contribute to better preventive and therapeutic measures planning to adopt on those fractures. Methods: 200 patients' files and x-rays with femoral shaft fractures have been retrospectively evaluated. Patients below the age of 10 years were not included because the treatment for this group was conservative. 25 files have been discarded for not supplying all the necessary data to the study. The patients were assessed for sex, age, side of the fracture, bone exposure, mechanisms of trauma, classification of the fractures, associated trauma, time for bone healing and types of surgical devices. Statistic analyses were made by chi-squared, Fisher and Student's-t tests, adopting as a significance level p<0.05. Results: significant results (p < 0.05) were found in: 70% of men, 80% closed fractures and 65% of women above the age of 60. Fractures resulting from simple falls were more frequent in women, above 60 years old, with simpler traces, and the ones caused by projectiles of firearm in men, from 20 to 60 years, with unstable traces. Trampling accidents were prevalent among youngsters between 10 and 19 years old. Car accidents showed all the types of fractures, mostly associated to other traumas, reaching its peak incidence in the age group of 20-30 years. The treatment with Küntscher Nail resulted in a longer mean consolidation time, as well as fractures with unstable traces (B3,C1,C2,C3). Conclusion: we found a bi-modal characteristic the femoral shaft fractures, consistently to literature data, where the high energy mechanisms (traffic accidents, high falls and wounds from firearms), have been more frequent in young adults, men, generating unstable traces of fractures, with more serious associated trauma, while the other group with low

    The first goal of this study was to determine if augmentation with an injectable, in situ setting, calcium-phosphate cement that is capable of being remodeled and was designed to mimic bone mineral significantly improved the strength and stiffness of fixation in a cadaveric femoral neck fracture model. The second goal was to determine if greater increases in fixation strength were achieved as the bone density of the specimen decreased. Sixteen pairs of fresh cadaveric human femora with a mean age of 70.9 years (SD = 17.2 years) were utilized. The bone density of the femoral neck was measured with dual-energy x-ray absorptiometry. The femoral head was impacted vertically with the femoral shaft fixed in 12 degrees of adduction using a materials testing machine to create a fully displaced fracture. Following fracture, 30% inferior comminution was created in each specimen. One randomly chosen femur from each pair underwent anatomic reduction and fixation with three cannulated cancellous bone screws, 7 mm in diameter, in an inverted triangle configuration. The contralateral femur underwent the same fixation augmented with calcium-phosphate cement. Specimens were preconditioned followed by 1.000 cycles to one body weight (611.6 N) at 0.5 Hz to simulate single-limb stance loading. The stiffness in the first cycle was observed to be significantly greater in cement-augmented specimens compared with unaugmented controls (p < 0.05). After cycling, each specimen was loaded at 10 mm/min until complete displacement of the fracture surface and failure of fixation occurred. Specimens augmented with bone mineral cement failed at a mean of 4,573 N (SD = 1,243 N); this was significantly greater (p < 0.01) than the mean for controls (3,092 N, SD = 1,258 N). The relative improvement in fixation strength (augmented/control x 100%) was not inversely correlated to femoral neck bone density (p = 0.25, R2 = 0.09), was weakly correlated to the volume of cement injected (p = 0.07, R2 = 0

    Bisphosphonates are the first line treatment for osteoporosis. Structurally, they are stable analogues of pyrophosphate and therefore exhibit a high affinity for bone mineral. They reduce bone loss by attenuating the ability of the osteoclast to resorb bone, decreasing activation frequency and the rate of remodelling. Large prospective randomized placebo-control trials provide unequivocal evidence for a reduction in the incidence of fractures.1 Impressively, 40 years since their first use in patients, the safety profile of bisphosphonates has been equally re-assuring.2 Questions have arisen lately as to whether bisphosphonates could cause atypical fractures, a rare type of atraumatic or minimal trauma femur fracture occurring below the great trochanter. This question has prompted calls for a broader examination of the long-term effects of bisphosphonate use. An attempt by the Food and Drug Administration (FDA) to garner consensus and provide definitive views was not successful.3 This has led to continued anxiety among treating physicians and patients alike, resulting in an overall reduction in prescriptions for bisphosphonates and for osteoporosis therapies in general. Here, we provide an overview of the current data on atypical fractures and bisphosphonate use. PMID:25294742

    Failed treatment of an intertrochanteric fracture typically leads to profound functional disability and pain. Salvage treatment with hip arthroplasty may be considered. The aim of this study was to evaluate the results and complications of hip arthroplasty performed as a salvage procedure after the failed treatment of an intertrochanteric hip fracture. Twenty-one patients were treated in our hospital with hip arthroplasty for failed treatment of intertrochanteric hip fracture. There were sixteen women and five men with a mean age of 75.8 years (range 61-85 years). Fourteen patients had failure of a previous nail fixation procedure, five had failure of a plate fixation, one of hip screws fixation and one of Ender nail fixation. In 19 out of 21 patients we performed a total hip arthroplasty-14 cases used modular implants with long-stems and five cases used a standard straight stem. In 2 of 21 cases we used a bipolar hemiarthroplasty. A statistically significant improvement was found comparing pre and postoperative conditions (p < 0.05). Our experience confirms that total hip arthroplasty is a satisfactory salvage procedure after failed treatment of an intertrochanteric fracture in elderly patients with few serious orthopaedic complications and acceptable clinical outcomes.

    Introduction: Subchondral insufficiency fracture (SIF) of femoral head is not very common cause of hip pain. This usually occurs in elderly osteoporotic patients or fatigue fracture in young military recruits. Case Report: We report a case of hip pain in an osteoporotic male which was diagnosed on MRI after the condition was missed by two physicians initially. Patient responded well to conservative treatment and was asymptomatic at one year follow up. Conclusion: Purpose of this case is to highlight clinical and radiological features of this entity and to discuss the prognosis and treatment. This case should increase awareness of this rare condition amongst treating physicians. This may facilitate early diagnosis and successful outcome with conservative treatment in selected sub-group of patients having SIF of femoral head.

    A 14-month-old girl was involved in a road traffic accident that resulted in an open book pelvic fracture and bilateral femoral fractures. Acute treatment involved a novel collar and the cuff pelvic closure technique to tamponade the pelvis and reduce bleeding. The patient was treated surgically with an external fixator, which provided good reduction of the pelvic and femoral fractures. A literature search found no previous information on open book pelvic fractures in infants younger than 2 years. The success of this surgery led us to suggest that the use of an external fixator is a potential treatment method for open book pelvic fractures and bilateral femoral fractures in extremely young infants.

    To compare the difference in efficacy following flexible intramedullary nailing (FIN) and external fixation (EF) for pediatric femoral shaft fractures. A systematic search was performed on PubMed, Embase, Medline, and Cochrane library for relevant studies. We included controlled trials comparing complications between FIN and EF for pediatric femoral shaft fractures published before 25 November 2014. Modified Jadad scores were utilized to assess the methodological quality of the studies included. The meta-analysis was carried out using Stata 12.0 software. Six studies involving 237 patients were included. On comparison of EF, a low incidence of overall complications [relative risk (RR)=0.30, 95% confidence interval (CI): 0.19-0.46; P<0.001] and pin-tract infection (RR=0.286, 95% CI: 0.13-0.61; P=0.001), but a high risk of soft tissue irritation (RR=1.86, 95% CI: 1.35-2.56; P<0.001) were found in patients treated with the FIN approach. No significant differences in other complications were found. On the basis of current evidence, the use of FIN leads to fewer complications than EF and may be considered as the first-line approach in the treatment of femoral shaft fractures. PMID:27294706

    Nonunion of femoral neck fractures following primary fixation and neglected femoral neck fracture in young adults is a challenging task. Every effort should be directed toward hip joint salvage in these patients. Among different available options of hip salvage, nonvascularized fibular graft (NVFG) osteosynthesis is simple, easy to perform, and a successful technique. In this review, the available literature on NVFG in neglected and nonunion femoral neck fractures has been analyzed. After review of 15 articles on NVFG, the average nonunion rate was estimated to be 7.86% (range 0-31%). Six articles that evaluated the preoperative and postoperative osteonecrosis reported improvement in 50% patients. The clinical and/or functional outcome was good to excellent in 56-96% patients following fibular osteosynthesis. Few complications such as coxa vara deformity, limb shortening, and intraarticular penetration of the graft or hardware have been reported. However, there are minimal donor site morbidities such as mild ankle pain, transient loss of toe flexors and extensors and transient lateral popliteal nerve palsy. PMID:27512214

    Introduction Internal fixation of undisplaced intracapsular femoral neck fractures with cannulated hip screws is a widely accepted surgical technique, despite reported failure rates of 12%-19%. This study determined whether preoperative serum albumin levels are linked to fixation failure. Methods We retrospectively reviewed 251 consecutive undisplaced intracapsular femoral neck fracture patients treated with cannulated hip screws in a district general hospital. Preoperative albumin levels were measured, and the fixation technique, classification and posterior tilt on radiography assessed. Fixation failure was defined as a screw cut, avascular necrosis (AVN) or non-union. Results Of the patients, 185 were female and 66 male. The mean age was 77 years (range 60-101 years). Thirty seven (15%) patients had fixation failure: 10 (4%) due to AVN; 12 (5%) due to non-union; and 15 (6%) due to fixation collapse. Low serum albumin levels were significantly associated with failure (p=0.01), whereas gender (p=0.56), operated side (p=0.62), age (p=0.34) and screw configuration (p=0.42) were not. A posterior tilt angle greater than 20° on lateral radiography significantly predicted failure (p=0.002). Conclusions Preoperative serum albumin is an independent predictor of cannulated hip screw fixation failure in undisplaced femoral neck fractures. Nutritional status should therefore be considered when deciding between surgical fixation and arthroplasty to avoid the possibility of revision surgery, along with an increased risk of morbidity and mortality.

    Objective To analyze infections of the surgical site among patients undergoing clean-wound surgery for correction of femoral fractures. Methods This was a historical cohort study developed in a large-sized hospital in Belo Horizonte. Data covering the period from July 2007 to July 2009 were gathered from the records in electronic medical files, relating to the characteristics of the patients, surgical procedures and surgical infections. The risk factors for infection were identified by means of statistical tests on bilateral hypotheses, taking the significance level to be 5%. Continuous variables were evaluated using Student's t test. Categorical variables were evaluated using the chi-square test, or Fisher's exact test, when necessary. For each factor under analysis, a point estimate and the 95% confidence interval for the relative risk were obtained. In the final stage of the study, multivariate logistic regression analysis was performed. Results 432 patients who underwent clean-wound surgery for correcting femoral fractures were included in this study. The rate of incidence of surgical site infections was 4.9% and the risk factors identified were the presence of stroke (odds ratio, OR = 5.0) and length of preoperative hospital stay greater than four days (OR = 3.3). Conclusion To prevent surgical site infections in operations for treating femoral fractures, measures involving assessment of patients’ clinical conditions by a multiprofessional team, reduction of the length of preoperative hospital stay and prevention of complications resulting from infections will be necessary.

    Bisphosphonate (BP) is a useful anti-resorptive agent which decreases the risk of osteoporotic fracture by about 50%. However, recent evidences have shown its strong correlation with the occurrence of atypical femoral fracture (AFF). The longer the patient takes BP, the higher the risk of AFF. Also, the higher the drug adherence, the higher the risk of AFF. It is necessary to ask the patients who are taking BP for more than 3 years about the prodromal symptoms such as dull thigh pain. Simple radiography, bone scan, and magnetic resonance imaging (MRI) are good tools for the diagnosis of AFF. The pre-fracture lesion depicted on the hip dual energy X-ray absorptiometry (DXA) images should not be missed. BP should be stopped immediately after AFF is diagnosed and calcium and vitamin D (1,000 to 2,000 IU) should be administered. The patient should be advised not to put full weight on the injured limb. Daily subcutaneous injection of recombinant human parathyroid hormone (PTH; 1-34) is recommended if the patient can afford it. Prophylactic femoral nailing is indicated when the dreaded black line is visible in the lateral femoral cortex, especially in the subtrochanteric area. PMID:26389082

    Femoral neck fractures in the young adult are a less common, but potentially functionally significant injury commonly occurring after high-energy trauma. The management goals of these injuries are the maintenance of a native hip joint absent avascular necrosis and nonunion. The primary determinant to this end is an anatomic reduction in displaced fractures with stable fixation. In this paper, the authors provide a set of technical tips and tricks to aid orthopedic surgeons in the surgical management of these injuries while reviewing the most recent literature available to inform clinical decision making. The paper includes the recommendations of the authors from the Denver Health Orthopaedic Trauma Service. PMID:26965005

    A three-year-old male working border collie with an infected femoral nonunion fracture was managed in a two-stage procedure involving debridement and omentalisation, followed by stabilisation with a bone plate and an autogenous cancellous bone graft. Osseous union was documented radiographically 16 weeks after surgery. Telephone follow-up one year later revealed the dog had returned to full working function without evidence of lameness. To the authors' knowledge, this is the first clinical case described in the veterinary literature using omentalisation as an adjunct to the management of an infected, biologically inactive nonunion fracture.

    Background Bisphosphonates (BPs) and other antiresorptive agents such as denosumab are widely prescribed for the treatment of osteoporosis and are also used in patients with multiple myeloma and metastatic breast or prostate cancer for avoiding bone reabsorption and fractures that result in increased morbidity-mortality among such individuals. Material and Methods We made a bibliographic search to analyze the concept, diagnosis and the different classifications for bisphosphonate-associated osteonecrosis of the jaws. Results Osteonecrosis of the jaws (ONJ) is an important complication of exposure to BPs or other antiresorptive agents, and although its prevalence is low, it can pose management problems. The definition, diagnosis and classification of osteonecrosis have evolved since Marx reported the first cases in 2003. Conclusions The present study offers a literature review and update on the existing diagnostic methods and classification of the disorder, with a view to facilitating earlier and more effective treatment. Key words:Osteonecrosis, jaws, bisphosphonates. PMID:26827066

    Purpose To evaluate the factors affecting the bone union time and the occurrence of nonunion after intramedullary nailing of subtrochanteric femoral fractures in adults. Materials and Methods We retrospectively reviewed data from 31 patients (22 men and 9 women) who had undergone femoral intramedullary nailing at least 1 year post-operatively and analyzed the bone union time, nonunion rates, and factors that affected the bone union time according to the fracture classification (AO and Fielding classifications), comminution of the medial cortex, reduction method, and additional cerclage wiring. Results The average union time was 26.4 weeks. There were no differences in the bone union time according to the fracture classification, reduction method, or additional cerclage wiring. Significant differences were found in the bone union time between the medial cortex comminution and non-comminution groups. A relatively strong positive correlation was detected between the degree of post-operative displacement and the bone union time. Nonunion occurred in three cases and there was no failure of implants. Conclusion The bone union time was not affected by the reduction method nor additional cerclage wiring in intramedullary nailing of subtrochanteric femur fractures. Comminution of the medial cortex and the degree of the postoperative displacement of fractures contributed to the delayed time of union.

    The first step in treatment of displaced femoral shaft fractures is adequate reduction of the fracture fragments. Manually performed, reduction can be challenging, and is frequently associated with soft tissue damage, especially when repeated reduction attempts are made. The magnitude of local and systemic inflammatory responses caused by prolonged and repeated reduction maneuvers has not been fully established. We devised an operative technique utilizing a robotic reduction device for use in a rat. A femoral fracture was simulated by means of an osteotomy. The robot enabled reproduction of both manual and guided precision reductions, performed in a single path movement. An external fixator was designed specifically to manipulate the rat femur and also for fixation of the osteotomy region. First, reduction accuracy was assessed in eight femurs, then the quality of fixator placement and reduction accuracy was analyzed in 22 femurs. In the first case, 100% of the femurs were accurately reduced. In the second case, 91% had successful stable fixation and an accurate reduction was achieved in 86% of the specimens. We demonstrated the feasibility of a model of robot-assisted fracture reduction that could be used to analyze the effects of reduction on the surrounding soft tissue via biochemical and histopathological means. A future aspect will be to evaluate whether the robot confers an advantage in fracture reduction versus the conventional technique, which would have significant implications for the use of robotic devices in orthopaedic surgery.

    Osteoporosis is a disease characterized by a low bone volume and deterioration of the bone quality, which increases the risk of low-energy fractures. Bisphosphonate (BP) treatment increases the bone mass and reduces the risk of fractures in patients with osteoporosis by suppressing bone resorption. In spite of its clinical benefits, the long-term use of BPs has been linked to the occurrence of atypical femoral fractures (AFFs). Although the evidence had been controversial regarding the association between the occurrence of AFFs and BP use, more recent studies with radiographic adjudication have indicated the significant associations between them. However, the pathogenesis of AFFs is not completely understood. The most popular hypothesis has suggested that the suppression of bone turnover by BPs is responsible; however, some recent reports have implied the involvement of pathophysiological alterations of the bone quality and fracture repair process. In this review, we summarize and discuss the epidemiology, risk factors and pathology of AFFs. PMID:26137208

    Periprosthetic proximal femoral fractures are a major challenge for the orthopaedic surgeon, with a continuously increasing incidence due to aging populations and concordantly increasing numbers of total hip replacements. Surgical decision-making mainly depends on the stability of the arthroplasty, and the quality of bone stock. As patients final outcomes mainly depend on early mobilization, a high primary stability of the construct is of particular relevance. Osteosynthetic procedures are usually applied for fractures with a stable arthroplasty, while fractures with a loosened endoprosthesis commonly require revision arthroplasty. Osteoporotic bone with insufficient anchoring substance for screws poses one major concern for cases with well-fixed arthroplasties. Complication rates and perioperative mortality have remained unacceptably high, emphasizing the need for new innovations in the treatment of periprosthetic fractures. Transprosthetic drilling of screws through the hip stem as the most solid and reliable part in the patient might represent a promising future approach, with auspicious results in recent biomechanical studies.

    Fragility hip fractures are increasingly common and hemiarthroplasty is one of the standard treatments. Although a common surgery, it should be performed with great caution because of the poor premorbid and bone quality in this demographic. Intra-operative fractures can occur while attempting press fit of the femoral implant. However; vigilance often steps down once the implant is secured and the hip reduced. This case report reminds surgeons that a large amount of torque can be transmitted during intra-operative positioning, such as during an attempt of hip dislocation. This torque, in addition to the risk factor of osteoporotic bone, can result in iatrogenic fractures. Published literature regarding management of an intra-operative fracture while the prosthetic hip is still reduced is lacking. The authors propose that temporary prophylactic cerclage wiring is a prudent and safe procedure prior to hip dislocation. PMID:26058283

    Objectives: To compare the demographics, metabolic bone health, radiologic features, treatment approaches and recurrence rates of pediatric versus young adult athletes with femoral neck stress fractures. Methods: A retrospective review was performed on all patients <45 years-old who were diagnosed with a femoral neck stress fracture at a single tertiary-care referral center from 2003-2015. Patients who had undergone previous hip surgery or had primary bone disorders/lesions were excluded. Variables analyzed included demographics, presenting symptoms, metabolic bone health (laboratory results, Dexa scores, menstrual history, eating disorder history), imaging, treatment approach and clinical course. Results: Forty-nine patients (mean age 21.4 years, range 5-44, 78% females) met study inclusion criteria, including 28 pediatric patients (mean age 14.4 years, range 5-19 years, 71% females) and 21 young adults (mean age 30.8 years, range 20-44 years, 86% females). A higher percentage of females was seen with each increasing decade of age, with 50% of pediatric patients under 11 years-old being male. Mean BMI was lower (p=0.04) in the pediatric group (20.6 kg/m2 +/-3.42) than the adult group (21.8 kg/m2 +/-2.04). Pain was the presenting complaint in all patients, with pain localized to the groin in 80% of cases. Participation in running sports was higher for the young adult cohort (86%) than the pediatric cohort (50%), while multiple sports were played more by pediatric patients (29%) than young adults (5%). History of previous acute fractures (2%) and previous stress fractures (14%) was identical between groups. Delayed menarche was recorded in 6% of pediatric patients, and menstrual irregularity was reported in 29% and 33% of pediatric and adult females, respectively. The base of the femoral neck was most common location for fracture in both pediatric (67%) and adult (81%) groups, while transcervical fractures were more likely to occur in pediatric (29%) than adult

    Purpose We aimed to evaluate the results of surgical treatment of periprosthetic femoral fractures in cementless total hip arthroplasty (THA). Materials and Methods From June 2002 to May 2012, 40 patients who could be followed-up for more than 1 year after surgery were enrolled in this study. The mean duration of follow-up was 28.5 months (range, 15-97 months) and the average age at the time of surgery was 71.5 years (range, 38-89 years). The fracture types were determined by using the Vancouver classification. Among intraoperative fractures, there were type A in 3 hips, type B2 in 2 hips and type B3 in one. Among postoperative fractures, type AG was present in 5 hips, type AL in 2 hips, type B1 in 15 hips, type B2 in 6 hips, type B3 in 3 hips, and type C in 3 hips. Evaluation of the results was based on bony union, stability of the prosthesis, postoperative complications, and Harris hip score at the final follow-up. Results Bony union was achieved in all but one case and the average time for bony union was 21 weeks. The mean Harris hip score was 86 at the final follow-up. Clinical results were above good in 34 of 40 hips (85.0%). Stem loosening occurred in one patient with a type B1 fracture treated with open reduction and plate fixation. Nonunion was observed in 1 patient with an AG type fracture. Conclusion Open reduction and fixation using a plate with a screw and cerclage wiring provided good results for periprosthetic fractures in patients who had a stable femoral stem without bone defects. Revision surgery with a cementless long stem should be considered in patients with an unstable stem or suspected stability in B1 type of THA using a proximal fixation type. PMID:27536618

    The high stiffness of conventional intramedullary (IM) nails may result in stress shielding and subsequent bone loss following healing in long bone fractures. It can also delay union by reducing compressive loads at the fracture site, thereby inhibiting secondary bone healing. This paper introduces a new approach for the optimization of a fiber-reinforced composite nail made of carbon fiber (CF)/epoxy based on a combination of the classical laminate theory, beam theory, finite-element (FE) method, and bone remodeling model using irreversible thermodynamics. The optimization began by altering the composite stacking sequence and thickness to minimize axial stiffness, while maximizing torsional stiffness for a given range of bending stiffnesses. The selected candidates for the seven intervals of bending stiffness were then examined in an experimentally validated FE model to evaluate their mechanical performance in transverse and oblique femoral shaft fractures. It was found that the composite nail having an axial stiffness of 3.70 MN and bending and torsional stiffnesses of 70.3 and 70.9 N⋅m², respectively, showed an overall superiority compared to the other configurations. It increased compression at the fracture site by 344.9 N (31%) on average, while maintaining fracture stability through an average increase of only 0.6 mm (49%) in fracture shear movement in transverse and oblique fractures when compared to a conventional titanium-alloy nail. The long-term results obtained from the bone remodeling model suggest that the proposed composite IM nail reduces bone loss in the femoral shaft from 7.9% to 3.5% when compared to a conventional titanium-alloy nail. This study proposes a number of practical guidelines for the design of composite IM nails. PMID:26458035

    Current clinical data suggest a higher failure rate for internal fixation in Vancouver type B1 periprosthetic femoral fracture (PFF) fixations compared to long stem revision in B2 fractures. The aim of this study was to compare the biomechanical performance of several fixations in the aforementioned fractures. Finite element models of B1 and B2 fixations, previously corroborated against in vitro experimental models, were compared. The results indicated that in treatment of B1 fractures, a single locking plate can be without complications provided partial weight bearing is followed. In case of B2 fractures, long stem revision and bypassing the fracture gap by two femoral diameters are recommended. Considering the risk of single plate failure, long stem revision could be considered in all comminuted B1 and B2 fractures. PMID:24035619

    The aim of this study was to compare the effectiveness and safety of 2 surgical techniques that are used to treat proximal femoral fractures.A systematic literature search (up to December 2014) was conducted in Medline, Embase, PubMed, and The Cochrane Central Register of Controlled Trials to screen for studies comparing proximal femoral nail antirotation (PFNA) with less invasive stabilization system-distal femur (LISS-DF) for proximal femoral fractures. Two authors independently assessed the methodological quality of the included studies and extracted data. Surgical information and postoperative outcomes were analyzed.A total of 7 studies with 361 patients who satisfied the eligibility criteria included 3 randomized controlled trials and 4 case-controlled trials associated with PFNA versus LISS in treating proximal femoral fractures. Our results demonstrated that there was a significant reduction in hospital stay and time to weight-bearing ambulation and bone healing for PFNA compared with LISS (odds ratio [OR] -1.48, 95% confidence interval [CI] -2.92 to -0.05; OR -7.08, 95% CI -8.32 to -5.84; OR -2.71, 95% CI -4.76 to 0.67). No statistically significant difference was observed between the 2 groups for operative time, blood loss volume, Harris hip score, and incidence of complications.Based on the results of this analysis, we inferred that PFNA is safer and more effective than reverse LISS-DF in patients undergoing osteosynthesis for proximal femoral fractures, and that PFNA is associated with reduced hospital stays and reduced time to weight-bearing ambulation and bone healing. Nonetheless, in certain cases in which PFNA is not suitable due to abnormal structure of the proximal femur or particularly unstable fractures, the LISS plate technique could be a useful alternative.

    The aim of this study was to describe risk factors for delirium and the impact of delirium on the rehabilitation outcome for patients operated for femoral neck fractures. Sixty-one patients, aged 70 years or older, consecutively admitted to the Department of Orthopaedic Surgery at Umeå University Hospital, Sweden for femoral neck fractures were assessed and interviewed during hospitalization and at follow up 4 months after surgery. Delirium occurred in 38 (62%) patients and those who developed delirium were more often demented and/or depressed. Patients with delirium were longer hospitalized and they were more dependent in their activity of daily living (ADL) on discharge and after 4 months. They had poorer psychological well-being and more medical complications than the nondelirious. A large proportion of the patients who developed delirium did not regain their previous walking ability and could not return to their prefracture living accommodation. Delirium after hip fracture surgery is very common especially among patients with dementia or depression. This study shows that delirium has a serious impact on the rehabilitation outcome from both short- and long-term perspectives. Because delirium can be prevented and treated, it is important to improve the care of elderly patients with hip fractures. PMID:15877637

    OBJECTIVE: To analyze the results of biomechanical assays of fixation of Pauwels type III femoral neck fracture in synthetic bone, using 7.5mm cannulated screws in inverted triangle formation, in relation to the control group. METHODS: Ten synthetic bones were used, from a domestic brand, divided into two groups: test and control. In the test group, a 70° tilt osteotomy of the femoral neck was fixated using three cannulated screws in inverted triangle formation. The resistance of this fixation and its rotational deviation were analyzed at 5mm displacement (phase 1) and 10mm displacement (phase 2). The control group was tested in its integrity until the fracture of the femoral neck occurred. The Mann-Whitney test was used for group analysis and comparison. RESULTS: The values in the test group in phase 1, in samples 1-5, showed a mean of 579N and SD =77N. Rotational deviations showed a mean of 3.33°, SD = 2.63°. In phase 2, the mean was 696N and SD =106N. The values of the maximum load in the control group had a mean of 1329N and SD=177N. CONCLUSION: The analysis of mechanical strength between the groups determined a statistically significant lower value in the test group. Level of Evidence III, Control Case. PMID:25246851

    Objective: Correlate the postoperative radiographic evaluation with variables accompanying acetabular fractures in order to determine the predictive factors for segmental impaction of femoral head. Methods: Retrospective analysis of medial files of patients submitted to open reduction surgery with internal acetabular fixation. Within approximately 35 years, 596 patients were treated for acetabular fractures; 267 were followed up for at least two years. The others were excluded either because their follow up was shorter than the minimum time, or as a result of the lack of sufficient data reported on files, or because they had been submitted to non-surgical treatment. The patients were followed up by one of three surgeons of the group using the Merle d'Aubigné and Postel clinical scales as well as radiological studies. Results: Only tow studied variables-age and amount of postoperative reductionshowed statistically significant correlation with femoral head impaction. Conclusions: The quality of reduction-anatomical or with up to 2mm residual deviation-presents a good radiographic evolution, reducing the potential for segmental impaction of the femoral head, a statistically significant finding.

    Summary We report a case of bilateral atypical femoral fractures that occurred in a patient who had been taking bisphosphonate long-term. A 36-year-old premenopausal female diagnosed with systemic lupus erythematosus and dermatomyositis had been treated with glucocorticoid and alendronate (5 mg/day) to prevent glucocorticoid-induced osteoporosis. She was taken to our hospital because she could not walk immediately after falling down from the standing position. A plain radiograph showed a subtrochanteric fracture of the left femur. Four months later, she fell again and sustained a contralateral subtrochanteric fracture. For each fracture, a femoral intramedullary nail was inserted. Delayed union was detected in both sides, and revision surgery with an iliac bone graft was required for implant breakage in the right side. Histomorphometric findings for the ilium revealed remarkably decreased osteoid volume with no osteoclasts and a minimally eroded surface, suggesting that bone turnover was severely suppressed. However, histology of the delayed union site revealed callus formation and some osteoclast appearance, suggesting that fracture healing was occurring. In total, it took 29 months (left) and 24 months (right) until fracture healing was achieved, showing delayed union. This case is extremely rare in that patient who presented with atypical femoral fractures in spite of her premenopausal status. The bone histomorphometric findings from this case suggest that severely suppressed bone turnover is associated with atypical femoral subtrochanteric fracture and can cause delayed union in patients treated with alendronate long-term.

    Objectives To determine patient independency, health-related and disease-specific quality of life (QOL), gait pattern, and muscle strength in patients after salvage arthroplasty for failed internal fixation of a femoral neck fracture. Design Secondary cohort study to a randomized controlled trial. Setting Multicenter trial in the Netherlands, including 14 academic and non-academic hospitals Patients Patients after salvage arthroplasty for failed internal fixation of a femoral neck fracture were studied. A comparison was made with patients who healed uneventfully after internal fixation. Intervention None (observatory study) Main outcome measurements Patient characteristics, SF-12, and WOMAC scores were collected. Gait parameters were measured using plantar pressure measurement. Maximum isometric forces of the hip muscles were measured using a handheld dynamometer. Differences between the fractured and contralateral leg were calculated. Groups were compared using univariate analysis. Results Of 248 internal fixation patients (median age 72 years), salvage arthroplasty was performed in 68 patients (27%). Salvage arthroplasty patients had a significantly lower WOMAC score (median 73 versus 90, P=0.016) than patients who healed uneventfully after internal fixation. Health-related QOL (SF-12) and patient independency did not differ significantly between the groups. Gait analysis showed a significantly impaired progression of the center of pressure in the salvage surgery patients (median ratio −8.9 versus 0.4, P=0.013) and a significant greater loss of abduction strength (median −25.4 versus −20.4 N, P=0.025). Conclusion Despite a similar level of dependency and QOL, salvage arthroplasty patients have inferior functional outcome than patients who heal after internal fixation of a femoral neck fracture.

    INTRODUCTION The removal of well-fixed broken femoral component and cement mantle can be extremely demanding, time consuming and potentially damaging to the host bone. Different methods have been described to extract broken femoral stem yet this remains one of the most challenging prospect to the revision hip surgeon. PRESENTATION OF CASE The authors present two cases underwent a modified sliding cortical window technique utilising a tungsten carbide drill, Charnley pin retractor and an orthopaedic mallet to aid extraction of a fractured cemented femoral stem in revision total hip arthroplasty. DISCUSSION The modified technique offers a simple and controlled method in extracting a well fixed fractured cemented femoral stem. It has the advantage of retaining the cement mantle with subsequent good seal of the femoral cortical window secured with cable ready system. Furthermore, tungsten carbide drill bit and Charnley pin retractor are relatively readily available to aid the extraction of the broken stem. Finally, it yields the option of implanting a standard femoral stem and obviates the need for bypassing the cortical window with long revision femoral component. CONCLUSION Fractured femoral stem is a rare yet a complex and very demanding prospect to both patients and hip surgeons. The sliding cortical window technique utilising tungsten carbide drill and Charnley pin retractor is technically easy and most importantly; preserves host bone stock with cement-in-cement revision hip arthroplasty. We believe this technique can be added to the armamentarium of revision hip surgeon when faced with the challenge of extracting a fractured cemented femoral stem. PMID:24858980

    This report addresses a new case of a modular femoral neck fracture after total hip arthroplasty. A now seventy-three-year- old overweight female underwent total hip replacement of the right hip because of osteoarthritis in the year 2002. Then, years later, the head and the polyethylene were changed due to wear. In October 2014, the patient was transferred from the trauma department of her hometown to our department after she had slipped and fallen directly on her right hip. The x-rays done at the trauma department have shown no periprosthetic fracture but a fracture of the modular neck. Therefore, the patient was transferred to our department in order to undergo a revision arthroplasty with change of the stem and head after splitting the femur. PMID:26157528

    Purpose The purpose of this study was to compare preoperative clinical outcomes before occurrence of periprosthetic femoral fracture (status before trauma) with postoperative clinical outcomes (status after operation) in patients with periprosthetic femoral fracture after hip arthroplasty. Materials and Methods A retrospective review was performed of all periprosthetic femoral fracture after hip arthroplasty treated surgically at our institution from January 2010 to January 2014. Among 29 patients who underwent surgical treatment for periprosthetic femoral fracture after hip arthroplasty, 3 patients excluded because of non-union of the fracture site. The clinical outcomes were determined by using visual analogue scale for pain (VAS), Harris hip score (HHS), and ambulatory ability using Koval classification. VAS, HHS and ambulatory ability was assessed for all the included patients at the last follow-up of status before trauma and after operation. Results The mean VAS, HHS and ambulatory ability at the last follow-up of status before trauma was 2.2 (range, 0-4), 78.9 (range, 48-92) and 1.9 (range, 1-5), respectively. The mean VAS, HHS and ambulatory ability at the last follow-up of status after operation was 3.1 (range, 1-5), 68.4 (range, 46-81) and 2.9 (range, 2-6), respectively. The clinical outcome of VAS, HHS and ambulatory ability were significantly worsened after surgical treatment for periprosthetic femoral fracture (P=0.010, P=0.001, and P=0.002, respectively). Conclusion Patients with periprosthetic femoral fracture after hip arthroplasty could not return to their status before trauma, although patients underwent appropriate surgical treatment and the fracture union achieved.

    The aim of this study was to perform a biomechanical analysis of the cement-in-cement (c-in-c) technique for fixation of selected Vancouver Type B1 femoral periprosthetic fractures and to assess the degree of cement interposition at the fracture site. Six embalmed cadaveric femora were implanted with a cemented femoral stem. Vancouver Type B1 fractures were created by applying a combined axial and rotational load to failure. The femora were repaired using the c-in-c technique and reloaded to failure. The mean primary fracture torque was 117 Nm (SD 16.6, range 89-133). The mean revision fracture torque was 50 Nm (SD 16.6, range 29-74), which is above the torque previously observed for activities of daily living. Cement interposition at the fracture site was found to be minimal. PMID:23146585

    Introduction Bilateral femoral neck fractures without major trauma are rare and related to several conditions. Insufficiency fractures due to the use of anti-epileptic drug are one of the rare causes. This case study is about bilateral femoral neck insufficiency fractures resulting from chronic use of anti-epileptic drug. Presentation of case A 26-year-old woman was referred to our emergency department with a complaint of bilateral groin pain and a 12-year history of irregular carbamazepine use. The diagnosis was bilateral femoral neck insufficiency fractures due to irregular long-term carbamazepine use. One-stage bilateral dynamic hip screw osteosynthesis was performed. After 2 years of follow up, good result was obtained. Discussion There are several risk factors for insufficiency fracture, and antiepileptic drug related osteoporosis is one of the reason. These drugs have negative effect on bone methabolism and bone mineral density. Conclusion To our knowledge, this is the first case in the literature of bilateral femoral neck insufficiency fracture due to chronic carbamazepine use. Joint and bone pain with a history of long-term use of anti-epileptic drug should be investigated carefully, and insufficiency fractures should be kept in mind. PMID:25528039

    The "Tobruk" technique of plaster augmentation of a Thomas' splint can be used for the treatment of femoral shaft fractures in children. The radiological and clinical data of 118 patients treated using this method were reviewed over a consecutive 3-year period. The mean age of the patients was 4.25 years. Mean hospital stay was 14.11 days. Mean time spent in the "Tobruk" splint was 44.77 days. Loss of reduction during splintage occurred in 9.32% of patients. Skin complications occurred in 5 patients (4.2%), and cast repairs were necessary in 3 patients. "Tobruk" splinting is a relatively safe and effective way of treating femoral shaft fractures in children. Although its use is not widespread, especially in the United States, until better results are achieved with spica casting and elastic stable intramedullary nails, it does provide a valid option in the treatment of these fractures. A controlled randomized prospective trial with long-term follow-up is needed to fully elucidate its value. PMID:16983865

    ABSTRACT OBJECTIVE : To investigate the influence of patients' age on the delay between diagnosis and surgical treatment of proximal femoral fractures METHODS : This is a retrospective study, con-ducted at a tertiary university hospital, including all patients admitted with proximal femoral fractures between March 2013 and March 2014. The participants were categorized into four groups according to age levels. The groups were compared according to demographics, comorbidities, fracture type, trau-ma circumstances, and time between diagnosis and surgical procedure RESULTS : One hundred and sixty one patients were included, 37 adults and 124 elderly. Among adults, the mean delay between diagnosis and surgical procedure was 6.4±5.3 days; among elderly the delay was 9.5±7.6 days. There was a progressive increase in the delay from the young-adults group through the elderly individuals (Kruskal-Wallis: 13.7; p=0.003) CONCLUSION : In spite of being the patients most susceptible to complications due to surgical delay, the elderly individuals pre-sented the longest delays from admission to surgical treatment.

    Bone metastasis resulting from breast cancer in pregnancy is rare. In the literature there are few reports regarding osteolytic lesions in pregnancy and no data on the treatment of such femoral fractures. The present study reports a case of a 29-week primigravida presenting with severe lumbosciatica in the left side, refractory to medical therapy. During neurosurgical examination a spontaneous pathological fracture of the left femur occurred. Damage control orthopedic principals were applied and a biopsy specimen from the femoral lesion was obtained, providing a diagnosis of metastases from breast adenocarcinoma. Cesarean section was performed at 32 gestational weeks. Following delivery, an internal fixator was placed in the left femur for definitive treatment of the fracture and staging of cancer was conducted. Subsequently, adjuvant treatment comprising left mastectomy and percutaneous radiofrequency thermoablation of the sacroiliac lesion were performed. A follow-up one-year following percutaneous radiofrequency thermoablation of the sacroiliac lesion detected no metastatic bone pain, and identified a stable sacroiliac lesion. PMID:26870230

    The authors investigated the use of an anti-rotation screw with the dynamic hip screw (DHS) during internal fixation of Garden I and II femoral neck fractures. Sixty-five patients with Garden I and II femoral neck fractures (mean age, 70 years) were treated with internal fixation at the authors' institution. In 31 patients, a 2-hole DHS was used alone (group 1), and in 34 patients, the DHS was combined with an anti-rotation screw placed in the cranial part of femoral head and neck (group 2). Patients' preinjury function and mental level were assessed using the Barthel index and the Abbreviated Mental test, respectively. The outcome measures included cost implications, operative time, and intraoperative radiation dose. The modified Harris Hip Score and a radiological assessment were performed at a mean of 11 months (range, 8-24 months) postoperatively. The use of the anti-rotation screw was associated with a longer operative time (mean, 44.54 minutes in group 1 vs 51.52 minutes in group 2; P<.0001) and more fluoroscopy screening (mean dose area product, 28.39 cGy/cm(2) in group 1 vs 44.33 cGy/cm(2) in group 2; P=.03). The additional cost of using an anti-rotation screw was £106 ($170) per case. No difference existed between the 2 groups with regard to radiological union, onset of avascular necrosis, and rate of revision surgeries. An anti-rotation screw, used with the dynamic hip screw, involves extra costs, prolongs operative time, and requires more intraoperative fluoroscopy screening but offers no advantages with regard to fracture union.

    2014-01-01

    Introduction : The rationale for operative treatment of depressed tibial plateau fractures is anatomic reduction, stable fixation and grafting. Grafting options include autogenous bone graft or bone substitutes. Methods : The autograft group included 18 patients with depressed tibial plateau fractures treated with autogenous bone grafting from the ipsilateral femoral condyle following open reduction and internal fixation. According to Schatzker classification, there were 9 type II, 4 type III, 2 type IV and 3 type V lesions. The average time to union and the hospital charges were compared with the bone substitute group. The latter included 17 patients who had an excellent outcome following treatment of split and/or depressed lateral plateau fractures, using a similar surgical technique but grafting with bone substitutes (allografts). Results : Excellent clinical and radiological results were detected in the autograft group after an average follow-up of 28 months (range 12-37). The average time to union in the autograft group was 14 weeks (range 12-16), while in the bone substitute group it was 18 weeks (range 16-20). The mean total cost was 1276 Euros for the autograft group and 2978 Euros for the bone substitute group. Discussion : The use of autogenous graft from the ipsilateral femoral condyle following open reduction and internal fixation of depressed tibial plateau fractures provided enough bone to maintain the height of the tibial plateau and was not associated with any donor site morbidity. Using this method, the surgical time was not significantly elongated and the rehabilitation was not affected. It also exhibited faster fracture healing without postoperative loss of reduction and it was less expensive than the use of bone substitutes. PMID:25317215

    This case demonstrates the potential serious consequences of the female athlete triad and its effects on bone. Displaced femoral neck stress fractures cause significant morbidity, and this case highlights the preventable nature of this injury. The treatment was focused on improving low energy availability, and, although challenging, improvements were made. This injury could have been prevented if the signs and symptoms of her injury had been addressed and there had been better knowledge of her risk factors. This case highlights the need for further education in the sports and health communities. PMID:23016107

    The authors report the case of an osteochondral fracture involving the weight-bearing portion of the lateral femoral condyle in a 23-year-old sportsman. The defect was concomitant to a lateral patellar dislocation involving a rare injury mechanism. Fixation of the osteochondral fragment was performed with bioabsorbable pins and healing was achieved within an acceptable time. Clinical and radiographic outcome at one year is highly satisfactory and bioabsorbable implant fixation reveals to be a worthwhile option in such a case. This rare lesion is diagnostically challenging and requires an adapted and prompt treatment. PMID:19251243

    Introduction: Extracorporeal Membrane Oxygenation (ECMO) is an invasive procedure used in critically ill patients with catastrophic pulmonary failure or cardiogenic shock in which conventional management has failed. These patients are managed with permanent anticoagulation, with increased bleeding risk. Hemorrhage is the main reported complication. Case: A 25-year-old polytraumatized woman, both lower limbs amputated and a left femoral shaft fracture with catastrophic pulmonary failure (Murray score 4) that required intensive management care with ECMO. During her evolution definitive femoral shaft osteosynthesis with a nail as required and the medical team decided to operate on the patient under ECMO. She recovered with fluctuations in her hematocrit, but was hemodynamically stable. The patient recovered satisfactorily, was weaned from ECMO and commenced her rehabilitation program. At 16 months, she was almost autovalent, and full consolidation was achieved, with no complication of the implants. Discussion: ECMO is a life-saving support, but requires permanent anticoagulation, which implies a high risk of hemorrhages, specially for surgical treatment. This patient underwent an osteosynthesis surgery satisfactorily. Hematoma was the only complication of her intramedullary femoral nail, without compromising hemodynamics. This case shows that patients on ECMO can undergo a major orthopedic surgery in selected cases. PMID:27194108

  4. Effect of Teriparatide on Healing of Atypical Femoral Fractures: A Systemic Review

    Background Bisphosphonates (BPs) are the most commonly used anti-osteoporotic drugs, which have been proven to reduce the risk of osteoporotic fractures. However, use of BPs, particularly for long periods of time, is associated with an increased risk of atypical femoral fracture (AFF). Healing of BP-associated AFF is usually delayed because of suppressed bone turnover. Teriparatide (TPTD), a recombinant form of parathyroid hormone (PTH), enhances bone healing in patients with delayed healing or non-union. Methods In this study, we summarized and performed a systemic review of the published literature on treatment of AFF using TPTD. Results Although there is a lack of level 1 studies on the evidence of TPTD in promoting bone union in AFFs, this systemic review of the available literature revealed that TPTD works positively in AFFs, and we put together the evidence that TPTD is a viable treatment option for enhancing fracture healing in AFFs. Conclusions While anecdotal evidence of beneficial effects of TPTD on fracture healing offer limited guidance for clinical decision making, a better understanding of the role of TPTD in fracture healing may be elucidated with future prospective trials.

    Background: Ununited femoral neck fracture is seen commonly in developing countries due to delayed presentation or failure of primary internal fixation. Such fractures, commonly present with partial or total absorption of femoral neck, osteonecrosis of femoral head in 8–30% cases with upward migration of trochanter posing problem for osteosynthesis, especially in younger individuals. Several techniques for treatment of such conditions are described like osteotomies or nonvascularied cortical or cancellous bone grafting provided varying degrees of success in terms of fracture union but unsatisfactory long term results occurred due to varying incidence of avascular necrosis (AVN) of femoral head. Moreover, in presence of AVN of femoral head neither free fibular graft nor cancellous bone graft is satisfactory. The vascularied bone grafting by deep circumflex iliac artery based on iliac crest bone grafting, free vascularied fibular grafting and muscle pedicle periosteal grafting showed high incidence of success rate. Osteosynthesis is the preferred treatment of choice in ununited femoral neck fracture in younger individuals. Materials and Methods: Of the 293 patients operated during the period from June 1977 to June 2009, 42 were lost to followup. Seven patients with gluteus medius muscle pedicle bone grafting (MPBG) were excluded. Thus, out of 244 patients, 208 (85.3%) untreated nonunion and 36 (14.7%) following failure of primary internal fixation were available for studies. Time interval between the date of injury and operation in untreated nonunion cases was mean 6.5 months and in failed internal fixation cases was mean 11.2 months. Ages of the patients varied from 16 to 55 years. Seventy patients had partial and 174 had subtotal absorption of the femoral neck. Evidence of avascular necrosis (AVN) femoral head was found histologically in 135 (54.3%) and radiologically in 48 (19.7%) patients. The patients were operated by open reduction of fracture, cannulated hip

    In contrast to traditional approaches to fracture risk assessment using clinical risk factors and bone mineral density (BMD), a new technique, reference point microindentation (RPI), permits direct assessment of bone quality; in vivo tibial RPI measurements appear to discriminate patients with a fragility fracture from controls. However, it is unclear how this relates to the site of the most clinically devastating fracture, the femoral neck, and whether RPI provides information complementary to that from existing assessments. Femoral neck samples were collected at surgery after low-trauma hip fracture (n = 46; 17 male; aged 83 [interquartile range 77-87] years) and compared, using RPI (Biodent Hfc), with 16 cadaveric control samples, free from bone disease (7 male; aged 65 [IQR 61-74] years). A subset of fracture patients returned for dual-energy X-ray absorptiometry (DXA) assessment (Hologic Discovery) and, for the controls, a micro-computed tomography setup (HMX, Nikon) was used to replicate DXA scans. The indentation depth was greater in femoral neck samples from osteoporotic fracture patients than controls (p < 0.001), which persisted with adjustment for age, sex, body mass index (BMI), and height (p < 0.001) but was site-dependent, being less pronounced in the inferomedial region. RPI demonstrated good discrimination between fracture and controls using receiver-operating characteristic (ROC) analyses (area under the curve [AUC] = 0.79 to 0.89), and a model combining RPI to clinical risk factors or BMD performed better than the individual components (AUC = 0.88 to 0.99). In conclusion, RPI at the femoral neck discriminated fracture cases from controls independent of BMD and traditional risk factors but dependent on location. The clinical RPI device may, therefore, supplement risk assessment and requires testing in prospective cohorts and comparison between the clinically accessible tibia and the femoral neck. © 2015 American Society for Bone and Mineral

    A retrospective review of 40 children aged 4 to 10 years with 46 femur fractures treated with open reduction and plate fixation is presented. Follow-up time was 6.3 years (range 2.5-17.5). There were no nonunions. One case of osteomyelitis and one refracture occurred. Leg-length discrepancy averaging 1.2 cm (range 0.4-1.8), with lengthening on the operated side, was observed in 15 patients. Although there is some risk for complications, and although good early results have been reported with elastic intramedullary nails, plate fixation continues to be a viable alternative in the surgical treatment of femoral shaft fractures in children aged 4 to 10.

    The inhibition of sclerostin by the systemic administration of a monoclonal antibody (Scl-Ab) significantly increased bone mass and strength in fractured bones in animal models and non-fractured bones in ovariectomised (OVX) rats. In this study, the effects of Scl-Ab on healing were examined in a closed fracture model in OVX rats. Sixty Sprague-Dawley rats underwent an ovariectomy or a sham operation at 4 months of age, and a closed fracture of the right femur was performed 3 months later. Subcutaneous injections with Scl-Ab (25 mg/kg) or saline were then administered on day 1 after the fracture and twice a week for 8 weeks (n = 20 per group), at which time the fractured femurs were harvested for micro-computed tomography analysis, four-point bending mechanical testing and histomorphometric analysis to examine bone mass, bone strength and dynamic bone formation at the fracture site. The angiogenesis at the fracture site was also examined. Bone marrow stem cells were also isolated from the fractured bone to perform a colony-forming unit (CFU) assay and an alkaline phosphatase-positive (ALP(+)) CFU assay. OVX rats treated with Scl-Ab for 8 weeks had significantly increased bone mineral density and relative bone volume compared with OVX rats treated with saline. Similarly, maximum loading, energy to maximum load and stiffness in Scl-Ab-treated OVX rats were significantly higher than those in saline controls. The mineral apposition rate (MAR), mineralising surface (MS/BS) and bone formation rate (BFR/BS) were also significantly increased in Scl-Ab-treated group compared with the saline-treated group in OVX rats. Furthermore, the Scl-Ab-treated group had more CFUs and ALP(+) CFUs than the saline-treated group in OVX rats. No significant difference in angiogenesis at the fracture site was found between the groups. Our study demonstrated that Scl-Ab helped to increase bone mass, bone strength and bone formation at the fracture site in a closed femoral fracture

    2014-01-01

    The radiographs of patients on long term bisphosphonates with atypical femur fractures demonstrate markedly thick cortices at the site of the fracture. We conducted a prospective clinical study to determine if cortical thickening is increased in long term bisphosphonate users. We recruited 43 patients who had taken bisphosphonates for more than 5 years. A group of 45 healthy volunteers and 12 patients recently diagnosed with osteoporosis served as controls. We measured the cortical thickening as the ratio of femoral cortical thickness to diameter of the femur, and looked for cortical beaking. No difference in the cortical thickness ratio was observed between long term bisphosphonate users and osteoporotic controls (0.53 vs. 0.54, p= 0.659). No cases of cortical beaking were seen and no increase in thigh pain was observed. The power of the study was 95% to detect a 10% difference in cortical thickness ratio. We conclude that long term bisphosphonate use does not produce a generalized increase in subtrochanteric femoral cortical thickening in the majority of patients. PMID:24468718

    2016-01-01

    Background: Intertrochanteric fracture is one of the most common fractures of the hip especially in the elderly with osteoporotic bones, usually due to low-energy trauma like simple falls. Dynamic Hip Screw (DHS) is still considered the gold standard for treating intertrochanteric fractures by many. Not many studies compare the DHS with Proximal femoral nail (PFN), in Type II intertrochanteric fractures (Boyd and Griffin classification). This study was done to compare the functional and radiological outcome of PFN with DHS in treatment of Type II intertrochanteric fractures. Methods: From October 2012 to March 2015, a prospective comparative study was done where 30 alternative cases of type II intertrochanteric fractures of hip were operated using PFN or DHS. Intraoperative complications were noted. Functional outcome was assessed using Harris Hip Score and radiological findings were compared at 3, 6, and 12 months postoperatively. Results: The average age of the patients was 60 years. In our series we found that patients with DHS had increased intraoperative blood loss (159ml), longer duration of surgery (105min), and required longer time for mobilization while patients who underwent PFN had lower intraoperative blood loss (73ml), shorter duration of surgery (91min), and allowed early mobilization. The average limb shortening in DHS group was 9.33 mm as compared with PFN group which was only 4.72 mm. The patients treated with PFN started early ambulation as they had better Harris Hip Score in the early post-op period. At the end of 12th month, there was not much difference in the functional outcome between the two groups. Conclusion: PFN is better than DHS in type II intertrochanteric fractures in terms of decreased blood loss, reduced duration of surgery, early weight bearing and mobilization, reduced hospital stay, decreased risk of infection and decreased complications.

    Reports linking long-term use of bisphosphonates (BPs) with atypical fractures of the femur led the leadership of the American Society for Bone and Mineral Research (ASBMR) to appoint a task force to address key questions related to this problem. A multidisciplinary expert group reviewed pertinent published reports concerning atypical femur fractures, as well as preclinical studies that could provide insight into their pathogenesis. A case definition was developed so that subsequent studies report on the same condition. The task force defined major and minor features of complete and incomplete atypical femoral fractures and recommends that all major features, including their location in the subtrochanteric region and femoral shaft, transverse or short oblique orientation, minimal or no associated trauma, a medial spike when the fracture is complete, and absence of comminution, be present to designate a femoral fracture as atypical. Minor features include their association with cortical thickening, a periosteal reaction of the lateral cortex, prodromal pain, bilaterality, delayed healing, comorbid conditions, and concomitant drug exposures, including BPs, other antiresorptive agents, glucocorticoids, and proton pump inhibitors. Preclinical data evaluating the effects of BPs on collagen cross-linking and maturation, accumulation of microdamage and advanced glycation end products, mineralization, remodeling, vascularity, and angiogenesis lend biologic plausibility to a potential association with long-term BP use. Based on published and unpublished data and the widespread use of BPs, the incidence of atypical femoral fractures associated with BP therapy for osteoporosis appears to be very low, particularly compared with the number of vertebral, hip, and other fractures that are prevented by BPs. Moreover, a causal association between BPs and atypical fractures has not been established. However, recent observations suggest that the risk rises with increasing duration of

    Purpose We aimed to evaluate the outcome of fixation with cannulated screws for valgus impacted femoral neck fractures in patients over 70 years of age. Materials and Methods We reviewed the outcome in 33 patients older than 70 years with valgus impacted femoral neck fractures who were treated with cannulated screws fixation from May 2007 to December 2010. These patients were followed for at least a year. We assessed the fixation failure rate, body mass index (BMI), bone mineral density (BMD) of proximal femur, distance between screw tip and joint, number of screws and time from fracture to operation. Results We identified six patients (18.2%) with failure. Two patients with subtrochanteric fractures through the screw insertion site and another patient with osteonecrosis were excluded from the fixation failure group. No difference was found in age, BMI, BMD of proximal femur, distance between screw tip and joint, number of screws and time from fracture to operation between failure and non-failure groups. Conclusion The failure rate of cannualted screw fixation for valgus impacted femoral neck fractures in the elderly patients was not low. Risk of failure should be considered in the management of these patients and accurate assessment for fracture type should be performed using computed tomogram and clinical evaluation.

    Autophagy, which is a mechanism for the turnover of intracellular molecules and organelles, protects cells during stress responses; however, the role of autophagy in the stages of bone fracture remains to be elucidated. The aim of the present study was to investigate the process of autophagy in bone tissue at different time-points after fracture. A femur fracture model was established in male adult Wistar rats via surgery. The protein expression of microtubule-associated protein II light chain 3 (LC3-II) was analyzed in a femur fracture (experimental) group and a sham-surgery group using immunofluorescence. The protein expression of proliferating cell nuclear antigen (PCNA) was used to investigate the cell proliferation in bone tissue following fracture via immunohistochemical analysis. The correlation between cell proliferation and autophagy was analyzed using linear regression. LC3-II protein was constitutively expressed in the sham-surgery group; however, compared with the expression in the sham-surgery group, the LC3-II expression in the experimental group was significantly increased at each time-point (P<0.05). Similarly, immunohistochemistry revealed that the number of PCNA-positive cells in each section was significantly increased following fracture injury (P<0.01). A comparison of the LC3-II- and PCNA-positive rates in the experimental group rats at each time-point revealed a linear correlation (R2=0.43, P<0.01). In conclusion, surgically induced fracture in rats is associated with an increase in LC3-II and PCNA protein expression during the initial stages of fracture injury, and a correlation exists between the expression of the two proteins. These results suggest that potential treatment aimed at improving fracture healing should target the process of autophagy. PMID:26640535

    Clinical prediction of bone fracture risk primarily relies on measures of bone mineral density (BMD). BMD is strongly correlated with bone strength, but strength is independent of fracture toughness, which refers to the bone’s resistance to crack initiation and propagation. In that sense, fracture toughness is more relevant to assessing fragility-related fracture risk, independent of trauma. We hypothesized that bone biochemistry, determined by Raman spectroscopy, predicts bone fracture toughness better than BMD. This hypothesis was tested in tumor necrosis factor-transgenic mice (TNF-tg), which develop inflammatory-erosive arthritis and osteoporosis. The left femurs of TNF-tg and wild type (WT) littermates were measured with Raman spectroscopy and micro-computed tomography. Fracture toughness was assessed by cutting a sharp notch into the anterior surface of the femoral mid-diaphysis and propagating the crack under 3 point bending. Femoral fracture toughness of TNF-tg mice was significantly reduced compared to WT controls (p=0.04). A Raman spectrum-based prediction model of fracture toughness was generated by partial least squares regression (PLSR). Raman spectrum PLSR analysis produced strong predictions of fracture toughness, while BMD was not significantly correlated and produced very weak predictions. Raman spectral components associated with mineralization quality and bone collagen were strongly leveraged in predicting fracture toughness, reiterating the limitations of mineralization density alone.

    Introduction: We report a case of an adolescent sustaining bilateral femoral neck fractures due to a first time epileptic seizure, as a result of expansion of his known syrinx. Case Report: A 19-year-old patient suffering from hypophosphatasia (HPP), Arnold-Chiari malformation, and a ventriculoperitoneal shunt sustained a trivial fall with profound pain and an inability to mobilize. Radiographs demonstrated a right-sided Garden-4 femoral neck and left-sided multi-fragmentary intracapsular/extracapsular fractures. The patient had previously suffered bilateral proximal femoral shaft fractures, treated with intramedullary unlocked nail fixation that was still in situ. Operative treatment with an exchange to Synthes Adolescent Lateral Recon nail was performed on the right with two Recon screws inserted into the femoral head. On the left, the existing Pedinail was preserved with an additional single screw inserted into the femoral head. In addition, 3 months of non-mobilization was required for adequate bone healing. After 1-year from time of injury, there is no avascular necrosis on radiographs and the patient is mobilizing pain-free. Conclusion: Patients with hypophosphatasia have delayed bone healing. We recommend surgical fixation with an intramedullary device and periods of non-mobilization until there is radiographical evidence of adequate bone healing. PMID:27299074

    Introduction: The best treatment for intertrochanteric fractures remains controversial. Many methods have been recommended. Aim: We aimed to assess the results of osteosynthesis using the Proximal Femoral Nail Antirotation (PFNA) system. Patients and Methods: We retrospectively analyzed 113 consecutive patients with intertrochanteric fractures treated with PFNA. Fractures were classified in accordance with the AO/OTA classification system into the groups A1, A2 and A3. The postoperative quality of fracture reduction was described as good, acceptable or poor. The location of the blade within the head was recorded as per the Cleveland method. Tip-apex distance (TAD) was used as a method for evaluating screw position. Pre-fracture and postoperative functional level were evaluated by the new mobility score (NMS). Results: The average age at the time of surgery was 75.9 years. The majority, 75 (66.3 %), were unstable fracture types. The reduction was good in 67 (61.4 %) cases. Of the 24 deaths, 19 patients had comorbidities (p < 0.001). The number of deaths in the first 6 months was significantly higher than in the next 6 months (p = 0.001). The mean TAD was 25.6 mm. The Cleveland zone centre-centre was the most common placement of the blade, accounting for 33 (29 %) of the cases. Reoperation was required in four patients. There were four patients with cut-out. The pre-facture mean value NMS was 8.6 (SD 1.1) and the postoperative mean value was 4.3 (SD 3.6). Conclusion: We concluded that PFNA offers biomechanical advantages, but the best position of the blade is still unknown. PMID:26843723

    INTRODUCTION Traumatic displaced femoral neck fractures in the elderly can be treated with cemented or uncemented hemiarthroplasty with good outcomes. Earlier studies reported a higher incidence of deep vein thrombosis (DVT) associated with cemented prostheses in elective total hip or knee arthroplasty. In addition, the hypercoagulable state after a traumatic femoral neck fracture and possible thrombogenic properties of bone cement could put these patients at greater risk for thromboembolism. We aimed to compare the incidence of DVT and progression to pulmonary embolism (PE) or mortality in cemented and uncemented hemiarthroplasty. METHODS The data of 271 patients treated with cemented or uncemented hemiarthroplasty after a traumatic displaced femoral neck fracture was retrospectively analysed for the incidence of DVT. The level of thrombosis, progression to PE and mortality were compared. RESULTS There were 133 (49.1%) patients with cemented hemiarthroplasty, while 138 (50.9%) had uncemented hemiarthroplasty. The patients had an average age of 76.6 (range 53–99) years and 11 (4.1%) patients had DVT. There were no significant differences in development of DVT, level of thrombosis, PE and mortality regardless of whether a cemented or an uncemented prosthesis was used. CONCLUSION Cemented hemiarthroplasty is not associated with higher risks of DVT, PE or mortality in patients with traumatic displaced femoral neck fracture. Cemented prostheses can be safely used for this group of patients. PMID:26892829

    This study aims to investigate the regional variations of trabecular morphological parameters and mechanical parameters of the femoral head, as well as to determine the relationship between trabecular morphological and mechanical parameters. Seven femoral heads from patients with fractured proximal femur were scanned using a micro-CT system. Each femoral head was divided into 12 sub-regions according to the trabecular orientation. One trabecular cubic model was reconstructed from each sub-region. A total of 81 trabecular models were reconstructed, except three destroyed sub-regions from two femoral heads during the surgery. Trabecular morphological parameters, i.e. trabecular separation (Tb.Sp), trabecular thickness (Tb.Th), specific bone surface (BS/BV), bone volume fraction (BV/TV), structural model index (SMI), and degree of anisotropy (DA) were measured. Micro-finite element analyses were performed for each cube to obtain the apparent Young's modulus and tissue level von Mises stress distribution under 1 % compressive strain along three orthogonal directions, respectively. Results revealed significant regional variations in the morphological parameters (). Young's moduli along the trabecular orientation were significantly higher than those along the other two directions. In general, trabecular mechanical properties in the medial region were lower than those in the lateral region. Trabecular mechanical parameters along the trabecular orientation were significantly correlated with BS/BV, BV/TV, Tb.Th, and DA. In this study, regional variations of microstructural features and mechanical properties in the femoral head of patients with proximal femur fracture were thoroughly investigated at the tissue level. The results of this study will help to elucidate the mechanism of femoral head fracture for reducing fracture risk and developing treatment strategies for the elderly.

    Introduction: Fracture of stems in primary total hip arthroplasty is a known complication and has been attributed to varus positioning, excessive weight of the patient, resorption of the femoral calcar and failure of the cement mantle. Fractures in uncemented revision femoral stems are rare and are attributed to reduction in proximal support either in the form of bone loss or an extended trochanteric osteotomy [ETO] against a distally well- fixed stem. Also, undersized stems and high BMI to increase the risk of stem fracture. Case Report: We report 3 cases of uncemented revision stem fractures. Case 1 is a 77 year old male, Case 2 is a 71- year-old female, case 3 an 82-year-old male. All three patients had significant proximal femoral osteolysis. All three had an extended trochanteric osteotomy for the revision surgery. The hips had remained in-situ for 4, 2 and 5 years respectively prior to fracture. Conclusion: When planning complex revision cases involving long uncemented stems, attention should be given to the above-mentioned variables. ETO non-union and proximal bone loss play an important role in stem fractures. Stem failure can occur irrespective of the make, and factors such as adequate stem size and good diaphyseal fit are non negotiable. PMID:27298992

    Osteoporotic fragility fractures of the femoral neck are the most common type of fractures in the elderly and are associated with a high mortality. Most frequently these fractures are due to falls but spontaneous onset has also been described. In these patients the insufficient quantity and quality of the osteoporotic bone finally leads to the development of a fragility or insufficiency fracture. In some cases of nondisplaced insufficiency fractures the diagnosis cannot be established by conventional radiographs alone and magnetic resonance imaging (MRI), single proton emission computed tomography (SPECT) or SPECT/CT are considered as diagnostic adjuncts. We report the case of an 83-year-old patient who had complained of ongoing weight-bearing pelvic pain for over 6 months. There was no history of trauma. The clinical conventional radiographs as well as CT could not elucidate the cause of the problems. To differentiate between lumbal and hip pain a SPECT/CT was performed and the diagnosis of a medial femoral neck insufficiency fracture was established. In the delayed phase a band-like increased tracer uptake within the medial femoral neck was observed. The SPECT/CT procedure is a promising diagnostic alternative for geriatric patients and can be particularly recommended in cases of persistent unclear pelvic or lumbar spine pain in the elderly.

    We report a 51-year old woman who suffered 2 atypical subtrochanteric femoral fractures (AFFs). She had a history of several metatarsal fractures. She had a normal bone densitometry. An adult form of hypophosphatasia (HPP) was diagnosed from low serum alkaline phosphatase (ALP), and tissue nonspecific isoenzyme of ALP (TNSALP) mutation analysis revealing 2 heterozygous mutations: c.299C>T (p. T100M) and c.571G>A (p. E191K). Low ALP is the hallmark of the diagnosis of HPP; which is associated in adults with premature loss of deciduous teeth, recurrent metatarsal stress fractures, and joints and tendons disorders. The incidence of AFFs in the population is 5.9 per 100,000 person-years. Physicians and patients with bone fragility must pay attention to prodromal pain, which require urgent radiographic evaluation of both femurs. Rheumatoid arthritis, use of glucocorticoids, and proton pump inhibitors have been associated with an excess risk of AFFs. Healthy subjects carrying a TNSALP mutation with low ALP value may be exposed to develop AFF spontaneously or while receiving potent anti-resorptive drugs. Low ALP must be checked as a cause of bone fragility. PMID:26992955

    This work aimed to compare the stress distribution and mechanical properties of our bridge combined fixation system and commonly used metal locking plate screw system by finite element analysis and by using the Zwick/Z100 testing machine. In addition, we also investigated the clinical outcome of our bridge combined fixation system for femoral fractures in 59 patients from June 2005 to January 2013. As a result, the stress distribution in the bone plate and screws of metal locking plate screw system during walking and climbing stairs was significantly lower than that of metal locking plate screw system. No significant difference in the displacement was observed between two systems. The equivalent bending stiffness of bridge combined fixation system was significantly lower than that of metal locking plate screw system. There were no significant differences in the bending strength, yield load, and maximum force between two systems. All the cases were followed up for 12-24 months (average 18 months). The X-ray showed bone callus was formed in most patients after 3 months, and the fracture line was faint and disappeared at 6-9 months postoperatively. No serious complications, such as implant breakage and wound infection, occurred postoperatively. According to self-developed standard for bone healing, clinical outcomes were rated as excellent or good in 55 out of 59 patients (success rate: 93.2%). Therefore, our findings suggest that our bridge combined fixation system may be a promising approach for treatment of long-bone fractures. PMID:25201264

    Unilateral stress fractures of the femoral neck are very uncommon and bilateral involvement is even rarer. They commonly occur in athletes, military recruits, older persons, or individuals with underlying metabolic disorders and very seldom in normal individuals. We present a rare case of simultaneous bilateral fracture neck of femur in a 25-year-old man who came with complaints of pain in bilateral groin for 1 month. There was no history of trauma or history suggestive of excessive activity prior to the onset of pain, but there was history of lifting heavy weights daily. On evaluation with MRI scan bilateral fracture of the femur neck was diagnosed and patient was operated on bilaterally with internal fixation done using dynamic hip screw. Patient then regained his routine activity over a period of 6 months and on follow-up at 1 year no avascular necrosis changes were seen in the femur head. We presented this case because of its unusual presentation and the diagnostic challenge it poses. PMID:26101680

    Periprosthetic femoral fracture (PFF) is a potentially devastating complication after total hip arthroplasty, with historically high rates of complication and failure because of the technical challenges of surgery, as well as the prevalence of advanced age and comorbidity in the patients at risk. This study describes the short-term outcome after revision arthroplasty using a modular, titanium, tapered, conical stem for PFF in a series of 38 fractures in 37 patients. The mean age of the cohort was 77 years (47 to 96). A total of 27 patients had an American Society of Anesthesiologists grade of at least 3. At a mean follow-up of 35 months (4 to 66) the mean Oxford Hip Score (OHS) was 35 (15 to 48) and comorbidity was significantly associated with a poorer OHS. All fractures united and no stem needed to be revised. Three hips in three patients required further surgery for infection, recurrent PFF and recurrent dislocation and three other patients required closed manipulation for a single dislocation. One stem subsided more than 5 mm but then stabilised and required no further intervention. In this series, a modular, tapered, conical stem provided a versatile reconstruction solution with a low rate of complications. PMID:26224817

    Objective: The objective of this paper is to measure the volume occupied by the most widely used internal fixation devices for treating femoral neck fractures, using the first 30, 40 and 50 mm of insertion of each screw as an approximation. The study aimed to observe which of these implants caused least bone aggression. Methods: Five types of cannulated screws and four types of dynamic hip screws (DHS) available on the Brazilian market were evaluated in terms of volume differences through water displacement. Results: Fixation with two cannulated screws presented significantly less volume than shown by DHS, for insertions of 30, 40 and 50 mm (p=0.01, 0.012 and 0.013, respectively), fixation with three screws did not show any statistically significant difference (p= 0.123, 0.08 and 0.381, respectively) and fixation with four cannulated screws presented larger volumes than shown by DHS (p=0.072, 0.161 and 0.033). Conclusions: Fixation of the femoral neck with two cannulated screws occupied less volume than DHS, with a statistically significant difference. The majority of screw combinations did not reach statistical significance, although fixation with four cannulated screws presented larger volumes on average than those occupied by DHS. PMID:27047886

    Introduction: Fractures of the proximal femur and hip are relatively common injuries in adults and common source of morbidity and mortality among the elderly. Many methods have been recommended for the treatment of intertrochanteric fractures. Material and methods: We retrospective analyzed all the patients with fractures of the hip treated with proximal femoral nail antirotation (PFNA) at the Clinic of Orthopedic and Traumatology, University Clinical Centre Tuzla from the first of January 2012 to 31 December 2012 years. The study included 63 patients averaged 73.6±11.9 years (range, 29 to 88 years). Fracture type was classified as intertrochanteric (Arbeitsgemeinschaft für Osteosynthesefragen classification 31.A.1, A.2 and A.3) and subtrochanteric fractures (Seinsheimer classification). Results and discussion: The ratio between the genders female-male was 1.6:1. There was statistically significant difference prevalence of female compared to male patients (p=0.012). There were 31 left and 32 right hip fractured. Low energy trauma was the cause of fractures in 57(90.5%) patients. Averaged waiting time for hospitalization was 3.2±7.5 days (range, 0 to 32 days). 44 patients were admitted the same day upon injuring. The average waiting time for the treatment was 3.6±5.7 days. The ratio between with or without co-existent disease was 4.7:1. During the three months postoperatively with ASA score 3 and 4 six patients died. There were no significant differences in deaths from ASA score 1 and 2 (p=0.52). Reoperation for the treatment of implant or fracture-related complications was required in three (4.7%) patients (infection, reimplantation and extraction). Three patient developed deep vein thrombosis. Statistically significant difference was found in the deaths in the first three months compared to the next three months (p=0.02). We found statistically significant difference between pre-injury and postoperative mobility score (p=0.0001). Conclusion: PFNA is an

    Subchondral insufficiency fracture of the femoral head (SIFFH) is characterized by acute onset hip pain without overt trauma. It appears as a low intensity band with bone marrow edema on T1-weighted MRI. The most common course of treatment is protected weight bearing for a period of several weeks. Total hip arthroplasty (THA) has been commonly used if the patient does not respond to the initial protected weight bearing treatment. We present a case of a 48-year-old male with SIFFH who was treated with core hip decompression and bone void filler as a hip-preserving alternative to THA. The patient has an excellent clinical and radiographic result at final follow up. Core hip decompression with bone void filler is a less invasive alternative to THA, and may be a preferred initial treatment strategy for SIFFH in the young and active patient who has failed conservative measures.

    Measurements of the humeral cortical thickness demonstrate that generalised osteoporosis in female Bantu commences in the fifth decade and gradually increases until, in the ninth decade, all subjects are osteoporotic. The combined cortical thickness (CCT) of the humerus in young adults is very similar to that found previously in a white London population and the loss of cortex with age is very similar. It is concluded that the known low incidence of femoral neck fracture in Bantu is not due to a lower incidence of generalised osteoporosis but to environmental factors. The chief environmental factor postulated is the greater amount of physical work performed by the Bantu. A more careful mode of walking is suggested as a subsidiary cause.

    Objective: We developed this study with the aim of evaluating the results from treating patients with proximal femoral fractures, in a series of cases. We sought to observe the influence of the most prevalent complications on the final results after a minimum follow-up of two years. We especially considered the relationship between establishment of avascular necrosis and the time between the accident and the therapeutic intervention. Method: We retrospectively studied proximal extremity fractures of the femur in 29 patients under 14 years of age between 1988 and 2007. We analyzed the following variables: sex, age, mechanism of injury, fracture classification (Delbet), treatment administered, complications (pseudarthrosis, varus deformity, leg length discrepancy and avascular necrosis), duration of surgery and results (Ratliff). We carried out individual descriptive analysis on each variable. The tests were used in accordance with the premise that normality applied. For the evaluation, we used Fisher's exact test. Results: Five patients (17.2%) had avascular necrosis, and three of them (60.0%) were over 10 years of age. 73.3% of the patients treated within the first 24 hours showed good results. The most common cause of fractures was traffic accidents (44.8%). The best results were observed among patients who were treated surgically. 41.4% developed some type of complication. Conclusions: Among the 29 patients treated, 58.6% had good, 27.6% had regular and 13.8% had poor results, according to the Ratliff criteria. When conservative treatment was applied, only 17.0% had good results, while 69.3% had good results from surgical intervention. Likewise, 73.3% of the results were good results when surgery was performed within the first 24 hours and only 42.8% of the results were good among patients who underwent surgery after this period. Patients operated within the first 24 hours developed necrosis of the femoral head in 13.3% of cases, while 21.4% of those operated

    Objective To improve the efficacy of closed reduction and wire guiding during intramedullary nail internal fixation in femoral shaft fractures. Methods A novel instrument was designed and manufactured. Sixty-eight patients were enrolled from February 2011 to December 2013. The instrument designed was used during the operation in the experimental group, but not in the control group. Results All patients exhibited fracture union, excluding 1 patient in the experimental group and 2 in the control group who had non-union; all of whom achieved fracture union with reoperation. There were no statistically significant differences in operative blood loss or duration of hospital stay between the groups (P > 0.05). The operative time, frequency of wire drilling, and number of open reduction cases, were significantly smaller in the experimental group than in the control group (P < 0.05). Conclusion Femoral shaft fractures are difficult to reduce using general methods; the novel instrument showed high clinical value and proved effective and safe in assisting with closed reduction and intramedullary nail fixation for femoral shaft fractures.

    Introduction Management of displaced fracture neck femur in the elderly population is frequently done by Hemiarthroplasty or Total Hip Replacement (THR). It avoids high rates of nonunion and avascular necrosis which usually occur after internal fixation of neck femur fractures in this age group. Aim The present study aimed to evaluate patient function and complications following hemiarthroplasty and total hip replacement in elderly population with displaced femoral neck fractures. Materials and Methods Patients above 60 years of age with displaced fracture neck femur were studied over the period of four years. All the clinical parameters and co-morbid conditions were noted at the time of presentation. The patients associated with co-morbid conditions and underlying pathology were excluded from study. Garden’s classification was used for classification of neck femur fractures. After due informed consent patients of displaced fracture neck femur were randomized by simple randomization and allocated for hemiarthroplasty or THR. Antibiotics were given preoperatively at the time of induction and postoperatively for 5-7 days. Surgery was carried out by Modified Gibson approach. Any complications during pre and postoperative period were noted. Follow-up of patients was done 1 month, 3 months, 6 months and 1 year interval with the help of Harris hip score. Results Total 80 patients were enrolled in the study group, with 40 patients in each group. The mean age of patients was 73 years in hemiarthroplasty group and 78 years in THR group. Female to male ratio was 55:45. Mean operative time was 35 minutes in hemiarthroplasty group and 45 minutes in THR. Average intraoperative blood loss was 200cc and 300cc in hemiarthroplasty and THR respectively. The mean hospital stay was 14 days in both the groups. Superficial wound infection was noted in hemiarthroplasty group while in THR group deep wound infection (n=1) and prolonged ICU stay (n=1) were noted. The mean Harris hip score

    Introduction Fractures of the neck of the femoral component have been reported in uncemented total hip replacements, however, to our knowledge, no fractures of the neck of a cementless forged titanium alloy femoral stem coated in the proximal third with hydroxy-apatite have been reported in the medical literature. Case presentation This case report describes a fracture of the neck of a cementless forged titanium alloy stem coated in the proximal third with hydroxy-apatite. Conclusion The neck of the femoral stem failed from fatigue probably because of a combination of factors described analytically below. PMID:18062807

    Three horses that were presented with supraglenoid tubercle fractures were treated with open reduction and internal fixation using distal femoral locking plates (DFLP). Placing the DFLP caudal to the scapular spine in order to preserve the suprascapular nerve led to a stable fixation, however, it resulted in infraspinatus muscle atrophy and mild scapulohumeral joint instability (case 1). Placing the DFLP cranial to the scapular spine and under the suprascapular nerve resulted in a stable fixation, however, it resulted in severe atrophy of the supraspinatus and infraspinatus muscles and scapulohumeral joint instability (case 2). Placing the DFLP cranial to the scapular spine and slightly overbending it at the suprascapular nerve passage site resulted in the best outcome (case 3). Only a mild degree of supraspinatus and infraspinatus muscle atrophy was apparent, which resolved quickly and with no effect on scapulohumeral joint stability. In all cases, fixation of supraglenoid tubercle fractures using DFLP in slightly different techniques led to stable fixations with good long-term outcome. One case suffered from a mild incisional infection and plates were removed in two horses. Placement of the DFLP cranial to the scapular spine and slightly overbending it at the suprascapular nerve passage prevented major nerve damage. Further cases investigating the degree of muscle atrophy following the use of the DFLP placed in the above-described technique are justified to improve patient outcome. PMID:27070124

    Elastic intramedullary (IM) devices, which avoid the physeal region like Nancy and Ender nails do, can be used in children younger than even 4 years without compromising the trochanter physis or risking an avascular necrosis. Intramedullary fixation of femoral shaft fractures leads to satisfactory results of alignment and union. Prerequisites for intramedullary closed nailing are a traction table, especially for older children and adolescents, and an image intensifer. Interlocking IM, Ender, and Nancy nails all have the equal advantage of early weight bearing and reduced hospitalization time compared with traction and cast management. Küntscher or interlocking nails should only be used in adolescents close to the end of growth to avoid growth arrest of the trochanterocervical physis. Küntscher nails and interlocking IM nails are both associated with the small but troublesome risk of avascular necrosis. Ender and Nancy nails, with retrograde or antegrade pinning, have a low complication rate and a short learning curve for surgeons. Overgrowth in late controls after IM rodding of shaft fractures is about the same as the other types of treatment with an average overgrowth of 7 mm. Short hospital stay for children with IM nails reduces cost of treatment to about one half compared with in-hospital traction and cast management. PMID:9165440

    The incidence of delirium, its predisposing factors, clinical profile, associated symptoms and consequences were investigated in 54 consecutive patients, 19 men and 35 women, mean age 77.1 years, admitted to an 'ortho-geriatric unit' with femoral neck fractures. The incidence of postoperative delirium was 15/54 (27.8%) and a logistic regression model found that dementia and a prolonged waiting time for the operation increased the risk of postoperative delirium. Delirium during the night was most common but in 5 patients the delirium was worst in the morning. Patients with delirium suffered more anxiety, depressed mood, emotionalism, delusions and hallucinations. A larger proportion of patients with delirium could not return to their previous dwelling, and a larger proportion of delirious patients were either dead, wheelchair-bound or bedridden at the 6-month follow-up (p < 0.005). The conclusion is that delirium is common and has a serious impact on the outcome after hip fracture surgery. PMID:10473932

    Objective To compare the functional results after displaced fractures of the femoral neck treated with internal fixation or hemiarthroplasty. Design Randomised trial with blinding of assessments of functional results. Setting University hospital. Participants 222 patients; 165 (74%) women, mean age 83 years. Inclusion criteria were age above 60, ability to walk before the fracture, and no major hip pathology, regardless of cognitive function. Interventions Closed reduction and two parallel screws (112 patients) and bipolar cemented hemiarthroplasty (110 patients). Follow-up at 4, 12, and 24 months. Main outcome measures Hip function (Harris hip score), health related quality of life (Eq-5d), activities of daily living (Barthel index). In all cases high scores indicate better function. Results Mean Harris hip score in the hemiarthroplasty group was 8.2 points higher (95% confidence interval 2.8 to 13.5 points, P=0.003) at four months and 6.7 points (1.5 to 11.9 points, P=0.01) higher at 12 months. Mean Eq-5d index score at 24 months was 0.13 higher in the hemiarthroplasty group (0.01 to 0.25, P=0.03). The Eq-5d visual analogue scale was 8.7 points higher in the hemiarthroplasty group after 4 months (1.9 to 15.6, P=0.01). After 12 and 24 months the percentage scoring 95 or 100 on the Barthel index was higher in the hemiarthroplasty group (relative risk 0.67, 0.47 to 0.95, P=0.02. and 0.63, 0.42 to 0.94, P=0.02, respectively). Complications occurred in 56 (50%) patients in the internal fixation group and 16 (15%) in the hemiarthroplasty group (3.44, 2.11 to 5.60, P<0.001). In each group 39 patients (35%) died within 24 months (0.98, 0.69 to 1.40, P=0.92) Conclusions Hemiarthroplasty is associated with better functional outcome than internal fixation in treatment of displaced fractures of the femoral neck in elderly patients.

    Osteonecrosis of the femoral head (ONFH) following femoral neck fractures is a rare, yet severe, disorder in children and adolescents. This study evaluated the effectiveness of core decompression (CD) combined with implantation of bone marrow–derived cells (BMDC) and rhBMP-2 for osteonecrosis of femoral head (ONFH) after femoral neck fractures in children and adolescents. This study included 51 patients, aged 11.4–18.1 years, with ARCO stages I–III ONFH after femoral neck fractures between 2004 and 2010. The hips were divided into two groups based on whether the lateral pillar of the femoral head (LPFH) was preserved: LPFH and non-LPFH groups. All patients were followed up clinically and radiographically for a minimum of 5 years. 44 patients (86.3%) had improved clinical outcome. Radiologically, 9 of the 51 hips (17.6%) exhibited collapse onset or progression of the femoral head or narrowing of the hip joint space, and one patient in the non-LPFH group required hip arthroplasty due to the worsened syndrome. The technique provided an effective therapeutic option for children and adolescents with ONFH following femoral neck fractures. It relieves hip pain and prevents the progression of osteonecrosis in young patients lasting more than 5 years after surgery. PMID:27477836

    The main objective of this study was to compare external fixation (EF) with elastic stable intramedullary nailing (ESIN) for the treatment of femoral shaft fractures in children aged 8 or younger. Fifteen children with femoral shaft fractures treated by EF and 23 children with femoral shaft fractures treated by ESIN were retrospectively reviewed. All patients were pain free at the last follow-up, with good ranges of motion in the hip and knee. Partial and full weight bearing occurred sooner in patients treated with EF than with ESIN, although more polytrauma patients were present in the ESIN group. In conclusion, EF and ESIN can be considered as safe and effective methods for femoral shaft fracture treatment in children younger than 8 years of age. PMID:27261769

    Almost 25% of all patients with hip fracture experience temporary confusion pre- and directly postoperatively due to trauma, advanced age, transport between units, and the use of analgesics, 35-50% of the patients suffer temporary or chronic decubitus. Analgesics often lead to nausea. A femoral nerve block can interrupt sensory impulses from the hip joint and provide complete pain relief without affecting the CNS, thus making preoperative care easier and postoperative rehabilitation can be started earlier. 80 consecutive patients with hip fracture were randomized to femoral nerve block or pharmacological treatment only. Paracetamol and tramadol were the standard analgesics used. All patients were followed up with regard to pain, duration of the block, number of analgesics doses, temporary confusion and time for postoperative mobilization. Pain was estimated by the patients using the visual analogue scale (VAS). A nerve block was performed to block the femoral nerve, the lateral femoral cutaneous nerve and the obturator nerve with 30 ml of ropivacaine 7.5 mg/ml. Mental status was evaluated with Pfeiffer-test. All patients experienced relatively intense pain on admission with an average VAS of 6. After nerve block the VAS was 2. Pain relief was the same in the control group. Pain relief was sustained for 15 hours. The time for mobilization after surgery was significantly lower, 23 hours compared to 36 for the control group. There was a lower number of patients temporarily confused in the block group compared to the control group, however no significant differences were seen. Femoral nerve block provides adequate pain relief, equivalent to pharmacological treatment in most patients. The time for postoperative mobilization was shorter and less temporary confusion was seen. There were no complications in this group, making nerve block a good alternative to traditional pharmacological preoperative treatment for patients with hip fractures. PMID:15282985

    Femoral neck fractures in the elderly are a common problem in orthopedics. Augmentation of screw fixation with bone cement can provide better stability of implants and lower the risk of secondary displacement. This study aimed to investigate whether cement augmentation of three cannulated screws in non-displaced femoral neck fractures could increase implant fixation. A femoral neck fracture was simulated in six paired human cadaveric femora and stabilized with three 7.3 mm cannulated screws. Pairs were divided into two groups: conventional instrumentation versus additional cement augmentation of screw tips with 2 ml TraumacemV+ each. Biomechanical testing was performed by applying cyclic axial load until failure. Failure cycles, axial head displacement, screw angle changes, telescoping and screw cut-out were evaluated. Failure (15 mm actuator displacement) occurred in the augmented group at 12,500 cycles (± 2,480) compared to 15,625 cycles (± 4,215) in the non-augmented group (p = 0.041). When comparing 3 mm vertical displacement of the head no significant difference (p = 0.72) was detected between the survival curves of the two groups. At 8,500 load-cycles (early onset failure) the augmented group demonstrated a change in screw angle of 2.85° (± 0.84) compared to 1.15° (± 0.93) in the non-augmented group (p = 0.013). The results showed no biomechanical advantage with respect to secondary displacement following augmentation of three cannulated screws in a non-displaced femoral neck fracture. Consequently, the indication for cement augmentation to enhance implant anchorage in osteoporotic bone has to be considered carefully taking into account fracture type, implant selection and biomechanical surrounding.

    We report our experience with 201 SEM bipolar prostheses used to treat femoral neck fractures in patients with a mean age of 70 years and a mean follow-up of 57 months (median 75 months). Clinical outcome was favorable with 94 per cent satisfactory results (very good and good). Femoral complications requiring reoperation (conversion to total hip replacement) occurred in 2.2 per cent of cases. Among the 163 patients for whom roentgenographic data were available, 5 (3.6 per cent) developed evidence of acetabular wear but remained symptom-free and did not require reoperation. As compared with Moore's prosthesis, the SEM bipolar prosthesis seems to provide substantially better clinical and roentgenographic results. For the treatment of femoral neck fractures, total hip replacement seems to provide results comparable to those reported here but requires a more sophisticated operative technique and carries a greater risk of subsequent dislocation. Two factors prevent the widespread use of the bipolar prosthesis at present: the need for femoral grouting which carries a well-documented risk of hemodynamic complications, and the higher cost of the device.

    Atypical femoral fractures are insufficiency fractures in the lateral femoral diaphysis or subtrochanteric region that mainly affect older patients on bisphosphonate therapy. Delayed healing is often seen in patients with incomplete fractures (cracks), and histology of bone biopsies shows mainly necrotic material inside the crack. We hypothesized that the magnitude of the strains produced in the soft tissue inside the crack during normal walk exceeds the limit for new bone formation, and thereby inhibit healing. A patient specific finite element model was developed, based on clinical CT images and high resolution μCT images of a biopsy from the crack site. Strain distributions in the femur and inside the crack were calculated for load cases representing normal walk. The models predicted large strains inside the crack, with strain levels above 10% in more than three quarters of the crack volume. According to two different tissue differentiation theories, bone would only form in less than 1-5% of the crack volume. This can explain the impaired healing generally seen in incomplete atypical fractures. Furthermore, the microgeometry of the crack highly influenced the strain distributions. Hence, a realistic microgeometry needs to be considered when modeling the crack. Histology of the biopsy showed signs of remodeling in the bone tissue adjacent to the fracture line, while the crack itself contained mainly necrotic material and signs of healing only in portions that seemed to have been widened by resorption. In conclusion, the poor healing capacity of incomplete atypical femoral fractures can be explained by biomechanical factors, and daily low impact activities are enough to cause strain magnitudes that prohibit bone formation.

    Metal-on-metal (MoM) bearing in total hip replacement (THR) has a high failure rate due to adverse reaction to metal debris (ARMD). There is a spectrum of soft tissue and bony changes in ARMD including muscle necrosis and osteolysis. In our institution, more than 1500 MoM THRs were implanted since 2003. Recently, we have revised significant numbers of these. We report our experience and management of a mode of failure of MoM THR that has been infrequently reported—the distal femoral stem fracture. We report on two patients who presented with worsening pain attributable to fracture of the femoral stem. Severe femoral osteolysis led to loss of proximal stem support and eventual fatigue fracture of the component. Both patients were revised employing a posterior approach. Bone trephine was used to extract a well-fixed distal stem fragment without any windows. Both patients had successful outcome after revision with excellent pain relief and no complications.

    Medial migration or cutout of the neck helical blade has commonly occurred in the treatment of trochanteric fracture of the femur. The position of the helical blade within the femoral head is one of the influencing factors that cause the blade to perforate the intact joint surface; however, the ideal placement of the helical blade is not currently known. A finite element model of a femur/nail construct was utilized to analyze five possible blade positions in the femoral head. Normal strain at the fracture surface, the minimum principal strain in the cancellous bone, and the von Mises stress in the implant itself were calculated and compared between different blade positions. The results showed that a large area of normal compressive strain at the fracture surface was observed in the inferior and posterior blade positions. The volume of cancellous bone strained to yielding in the femoral head and neck was lower for the inferior and posterior positions, whereas it was the highest for the superior position. The inferior and posterior positions had lower von Mises stress in the implant itself. The inferior and posterior positions may be the ideal position for the intramedullary nail with a helical neck blade. PMID:26351785

    Total hip arthroplasty for intracapsular femoral neck fractures (FNF) is associated with a greater risk of dislocation. Dual articulation systems in this group of patients may provide better implant stability and a reduced dislocation rate. The aim of our study was to investigate FNF patients treated with dual articulation cups (DAC) and conventional THA and compare their clinical results at four months and one year after surgery. Our study compared femoral neck fracture patients treated with either DAC or conventional THA during two different time periods. Before surgery and during follow-up, the patients answered questions regarding their mobility, pain and usage of walking aids. Additionally at four-month and one-year follow-ups EQ-5D and HOOS questionnaires were applied for those patients qualifying for functional and quality of life analysis. Out of 125 femoral neck fracture patients 58 were treated with DAC and 67 with conventional THA. At four months and one year follow-up the HOOS and EQ-5D results did not differ significantly between DAC and conventional THA. Five hips in the THA group were revised for recurrent dislocation and two had a single dislocation. One year after surgery, the functional result of DAC and conventional THA are comparable but DAC have a lower risk of dislocation. PMID:23397197

    Purpose To compare the clinical and radiological results between internal fixation using the proximal femoral nail system and bipolar hemiarthroplasty (BHA) in reverse oblique intertrochanteric hip fractures in elderly patients. Materials and Methods From January 2005 to July 2012, we reviewed the medical records of 53 patients who had been treated surgically for reverse oblique intertrochanteric fracture and had been followed-up on for a minimum of two years. All patients were ≥70 years of age, and divided into two groups for retrospective evaluation. One group was treated with internal fixation using the proximal femoral nail system (31 cases), and the other group was treated with BHA (22 cases). Results Early ambulation postoperatively and less pain at postoperative three month were significantly superior in the BHA group. However, by 24 months postoperatively, the internal fixation group exhibited higher Harris scores and correspondingly less pain than the BHA group. There were no significant differences in union rate, duration of hospitalization or lateral wall fracture healing between the two groups. Four patients in the internal fixation group underwent reoperation. Conclusion In the treatment of intertrochanteric fracture of the reverse oblique type, open reduction and internal fixation should be considered to be the better choice for patients with good health and bone quality. However, in cases of severe comminition of fracture and poor bone quality, BHA is an alternative offering advantages including early ambulation, less pain at early stages, and a lower risk of reoperation.

    In this paper, a computerized fluoroscopy with zero-dose image updates for femoral diaphyseal fracture reduction is proposed. It is achieved with a two-step procedure. Starting from a few (normally 2) calibrated fluoroscopic image, the first step, data preparation, automatically estimates the size and the pose of the diaphyseal fragments through three-dimensional morphable object fitting using a parametric cylinder model. The projection boundary of each estimated cylinder, a quadrilateral, is then fed to a region information based active contour model to extract the fragment contours from the input fluoroscopic images. After that, each point on the contour is interpolated relative to the four vertices of the corresponding quadrilateral, which resulted in four interpolation coefficients per point. The second step, image updates, repositions the fragment projection on each acquired image during bony manipulation using a computerized method. It starts with interpolation of the new position of each point on the fragment contour using the interpolation coefficients calculated in the first step and the new position of the corresponding quadrilateral. The position of the quadrilateral is updated in real time according to the positional changes of the associated bone fragments, as determined by the navigation system during fracture reduction. The newly calculated image coordinates of the fragment contour are then fed to a OpenGL® based texture warping pipeline to achieve a real-time image updates. The presented method provides a realistic augmented reality for the surgeon. Its application may result in great reduction of the X-ray radiation to the patient and to the surgical team.

    Compartment syndrome is known to develop after a prolonged surgery in the lithotomy position. We experienced acute renal failure following compartment syndrome after the surgery in hemilithotomy position. A 62-year-old man underwent a left hip fixation for femoral neck fracture. The surgical leg was placed into traction in a foot piece and the intact leg was placed in the hemilithotomy position. Because of the difficulty in repositioning and the trouble with fluoroscope, the surgery took over 5 hours. He suffered acute pain, swelling and spasm in his intact leg placed into hemilithotomy after the surgery. Creatine kinase, blood urea nitrogen and creatinine markedly increased and myoglobinuria was recognized. We diagnosed an acute renal failure following compartment syndrome and treated him in the ICU on close monitoring. In spite of the treatment with massive transfusion and diuretics, he needed hemodialysis twice and then his renal function improved. Prevention is most essential for compartment syndrome after a prolonged surgery in the lithotomy position. Risk factors should be recognized before surgery and appropriate action should be taken such as using Allen stirrups and avoiding hypotension, hypovolemia and the prolonged lithotomy position with exaggerated elevation of legs.

    Background Non-communicable diseases like hip fractures are a significant problem in a developing country like India. The risk factors for hip fractures vary according to local practices and the availability of preventive health care delivery systems. There is paucity of data on risk factors for hip fracture in the south Indian population. Aim This study was undertaken to assess risk factors associated with femoral neck (FN) fracture in South Indian postmenopausal women along with subsequent one year mortality. Materials and Methods One hundred four postmenopausal women with FN fracture and 104 age and BMI matched controls were included. Sedative use, visual impairment and other relevant risk factors were assessed. Bone biochemistry and Bone Mineral Density (BMD) were evaluated. A telephonic interview was done at the end of one year to ascertain the well-being. Results Sedative use, visual impairment, low FN BMD and vitamin-D deficiency (<20 ng/ml) were seen more in fracture subjects compared to controls (p≤0.05). At the end of one year, 20% of the fracture subjects and 5% of the controls had died (p=0.001). Conclusion Risk factors identified in our study are potentially correctable, and needs special attention in an Indian context to prevent hip fractures. PMID:26266149

    Periprosthetic femoral fracture (PFF) is a complicated complication of both primary and revision hip arthroplasty with an increasing incidence.

    Abstract Periprosthetic femoral fracture (PFF) is a complicated complication of both primary and revision hip arthroplasty with an increasing incidence. The present study aimed to summarize the clinical characteristics and identify the risk factors for PFF which would be potentially helpful in the prevention and treatment of PFF. We retrospectively analyzed the clinical data of 89 cases of PFF, and a case–control study was designed to identify the potential risk for intraoperative and postoperative PFF in both primary and revision hip arthroplasty. The overall incidence of PFF was 2.08% (intraoperative: 1.77%, postoperative: 0.30%, revision: 13.60%, and primary: 0.97%). The most commonly used treatment strategy was fixation with cerclage wire or band for intraoperative PFF, whereas long stem revision with plate or cortical allograft strut fixation was the main treatment strategy for postoperative PFF. The risk factors for intraoperative PFF in primary total hip arthroplasty (THA) included the diagnosis of development dysplasia of the hip (DDH) (odds ratio [OR] = 5.01, 95%CI, 1.218–20.563, P=0.03) and CBR ≥ 0.49 (OR = 3.34, 95%CI, 1.138–9.784, P = 0.03). The increased age was associated with increased incidence of postoperative PFF in primary THA (OR = 1.09, 95%CI, 1.001–1.194, P = 0.04). As for the intraoperative PFF in revision THA, we found that receiving multiple operations before revision (OR = 2.45, 95%CI, 1.06–5.66, P = 0.04), revisions due to prosthetic joint infection (OR = 6.72, 95%CI, 1.007–44.832, P = 0.04), the presence of cementless implant before revision (OR = 13.54, 95%CI, 3.103–59.08, P = 0.001), and femoral deformity (OR = 8.03, 95%CI, 1.656–38.966, P = 0.01) were all risk factors.

    Purpose: We investigated the clinical and dosimetric predictors for radiation-associated femoral fractures in patients with proximal lower extremity soft tissue sarcomas (STS). Methods and Materials: We examined 131 patients with proximal lower extremity STS who received limb-sparing surgery and external-beam radiation therapy between 1985 and 2006. Five (4%) patients sustained pathologic femoral fractures. Dosimetric analysis was limited to 4 fracture patients with full three-dimensional dose information, who were compared with 59 nonfracture patients. The mean doses and volumes of bone (V{sub d}) receiving specified doses ({>=}30 Gy, 45 Gy, 60 Gy) at the femoral body, femoral neck, intertrochanteric region, and subtrochanteric region were compared. Clinical predictive factors were also evaluated. Results: Of 4 fracture patients in our dosimetric series, there were three femoral neck fractures with a mean dose of 57.6 {+-} 8.9 Gy, V30 of 14.5 {+-} 2.3 cc, V45 of 11.8 {+-} 1.1 cc, and V60 of 7.2 {+-} 2.2 cc at the femoral neck compared with 22.9 {+-} 20.8 Gy, 4.8 {+-} 5.6 cc, 2.5 {+-} 3.9 cc, and 0.8 {+-} 2.7 cc, respectively, for nonfracture patients (p < 0.03 for all). The femoral neck fracture rate was higher than at the subtrochanteric region despite lower mean doses at these subregions. All fracture sites received mean doses greater than 40 Gy. Also, with our policy of prophylactic femoral intramedullary nailing for high-risk patients, there was no significant difference in fracture rates between patients with and without periosteal excision. There were no significant differences in age, sex, tumor size, timing of radiation therapy, and use of chemotherapy between fracture and nonfracture patients. Conclusions: These dose-volume toxicity relationships provide RT optimization goals to guide future efforts for reducing pathologic fracture rates. Prophylactic femoral intramedullary nailing may also reduce fracture risk for susceptible patients.

    We report the outcome of 39 patients who underwent a modified Pauwels' intertrochanteric osteotomy for nonunion of a femoral neck fracture following failed osteosynthesis. There were 31 men and eight women with a mean age of 47.2 years (34 to 59). By Pauwels' classification, there were 11 Type II fractures and 28 Type III fractures. The mean follow-up was 7.9 years (2 to 19). In the 11 patients whose initial treatment had been osteotomy, union was achieved in nine (81.8%). In 28 patients whose initial treatment had been with a lag screw or a dynamic hip screw, union was achieved in 27 (96.4%). Limb lengths were equalised in 14 of 16 patients (87.5%) with pre-operative shortening. The mean neck-shaft angle improved significantly from 100.5° (80° to 120°) to 131.6° (120° to 155°) (p = 0.004). The mean modified Harris hip score was 85.6 points (70 to 97) and the mean modified Merle d'Aubigné score was 14.3 (11 to 18). Good to excellent functional outcomes were achieved in 32 patients (88.8%). A modified Pauwels' intertrochanteric osteotomy is a reliable method of treating ununited fractures of the femoral neck following failed osteosynthesis: coxa vara and shortening can also simultaneously be addressed.

    A 2-year-old, egg-laying maroon-bellied conure (Pyrrhura frontalis) was referred for treatment of bilateral femoral fractures believed to be secondary to recent egg laying and nutritional and husbandry deficiencies. On radiographs, all skeletal components were diffusely osteopenic, precluding surgical fixation. A novel device to stabilize the bilateral femoral fractures was manufactured with polyvinyl chloride piping, which braced the bird's feet at the level of the perch and supported its upper body weight via a breast plate, thus maintaining the bird in a physiologically appropriate perching position. The conure was ambulatory and returned to normal function after 3 weeks of external coaptation with this device. After 6 weeks, callus formation was palpable over both fracture sites even though minimal bone remodeling was visible radiographically. This body splint device may present a viable alternative to euthanasia in select cases of bilateral femoral fractures in companion birds. PMID:27315387

    Osteonecrosis in isolated fractures of the acetabulum without dislocation of hip seems to be a known complication, but to our knowledge it has not been reported adequately. The causative nature of post-traumatic femoral head osteonecrosis has not been studied critically. The pathophysiology of osteonecrosis in this case also eludes us. Striking evidence points towards the intra-operative blood loss and low mean arterial pressure possibly leading to hypo-perfusion of femoral head leading to osteonecrosis. Fractures of the acetabulum pose a difficult problem for the patient and the surgeon because of possible complications. Thus any surgeon involved in surgery for fractures of the acetabulum should be aware of the possibility of this potential complication. Here is a 61-year male, who sustained a complex fracture of the acetabulum without hip dislocation, subsequently was treated surgically with internal fixation using an anterior approach, 10 months after surgery patient developed osteonecrosis of the femoral head.

    This retrospective study presents the experience gained through use of reamed femoral nails and reports results and respective complications. This study included 415 femur fractures (312 men and 101 women with a mean age of 27.8 years) that were treated from 1993 to 2004. The fractures were classified according to AO, and 74 open fractures were included and typed according to the Gustilo classification. Dynamic nailing was performed for nearly all type A fractures and static nailing for types B and C. After a mean follow-up of 1.5 years, union rate was 97.8%. The complications were: 9 non-unions, 14 delayed-unions, 4 torsional malunions, 6 limb length discrepancies (shortening) and 30 nerve pareses due to traction. Deep venous thrombosis (DVT) occurred below the knee in 4 patients, while there were recorded 3 pulmonary and 2 fat embolisms, 1 superficial and 1 deep infection. There were 28 broken screws identified postoperatively. Logistic regression analysis revealed that type B and C were associated with increased risk of complications, with respective odds ratios of 3.1 (95% CI = 1.3–7.2, P = 0.011) and 4.3 (95% CI = 1.8–10.3, P = 0.001) when compared to type A patterns. All patients returned to their activities in a mean time of 10 months. Intramedullary nailing is still the treatment of choice for femoral shaft fractures, but knowledge of potential complications and their association with certain fracture patterns is needed.

    Periprosthetic fractures after total knee arthroplasty (TKA) present a clear management challenge, and retrograde intramedullary nails have recently gained widespread acceptance in treatment of these fractures. In two cases, we found a blocking screw technique, first reported by Krettek et al., was useful in the reduction of the fractures. Both patients attained preinjury mobility after intramedullary nailing. Moreover, we present a chart summarizing the notch designs of various femoral components because some prosthetic knee designs are not amenable to retrograde nailing. We hope this will be helpful in determining indications for retrograde nailing in periprosthetic fractures after TKA. PMID:25574411

    Atypical femoral fractures (AFF) associated with long-term bisphosphonates (LTB) are a growing concern. Their etiology is unknown, but bone material properties might be deteriorated. In an AFF series, we analyzed the bone material properties by microindentation. Four groups of patients were included: 6 AFF, 38 typical osteoporotic fractures, 6 LTB, and 20 controls without fracture. Neither typical osteoporotic fractures nor controls have received any antiosteoporotic medication. A general laboratory workup, bone densitometry by dual-energy X-ray absorptiometry (DXA), and microindentation testing at the tibia were done in all patients. Total indentation distance (Total ID), indentation distance increase (IDI), and creep indentation distance (Creep ID) were measured (microns). Age-adjusted analysis of covariance (ANCOVA) was used for comparisons. Controls were significantly younger than fracture groups. Bisphosphonate exposure was on average 5.5 years (range 5 to 12 years) for the AFF and 5.4 years (range 5 to 8 years) for the LTB groups. Total ID (microns) showed better material properties (lower Total ID) for controls 36 (± 6; mean ± SD) than for AFF 46 (± 4) and for typical femoral fractures 47 (± 13), respectively. Patients on LTB showed values between controls and fractures, 38 (± 4), although not significantly different from any of the other three groups. IDI values showed a similar pattern 13 (± 2), 16 (± 6), 19 (± 3), and 18 (± 5). After adjusting by age, significant differences were seen between controls and typical (p < 0.001) and atypical fractures (p = 0.03) for Total ID and for IDI (p < 0.001 and p < 0.05, respectively). There were no differences in Creep ID between groups. Our data suggest that patients with AFF have a deep deterioration in bone material properties at a tissue level similar to that for the osteoporotic fracture group. The LTB group shows levels that are in between controls and both type of

    Background Femoral neck fractures in the elderly are frequent, represent a great health care problem, and have a significant impact on health insurance costs. Reconstruction options using hip arthroplasty include unipolar or bipolar hemiarthroplasty (HA), and total hip arthroplasty (THA). The purpose of this review is to discuss the indications, limitations, and pitfalls of each of these techniques. Methods The Pubmed database was searched for all articles on femoral neck fracture and for the reconstruction options presented in this review using the search terms "femoral neck fracture", "unipolar hemiarthroplasty", "bipolar hemiarthroplasty", and "total hip arthroplasty". In addition, cross-referencing was used to cover articles eventually undetected by the respective search strategies. The resulting articles were then reviewed with regard to the different techniques, outcome and complications of the distinct reconstruction options. Results THA yields the best functional results in patients with displaced femoral neck fractures with complication rates comparable to HA. THA is beneficially implanted using an anterior approach exploiting the internervous plane between the tensor fasciae latae and the sartorius muscles allowing for immediate full weight-bearing. Based on our findings, bipolar hemiarthroplasty, similar to unipolar hemiarthroplasty, cannot restorate neither anatomical nor biomechanical features of the hip joint. Therefore, it can only be recommended as a second line of defense-procedure for patients with low functional demands and limited live expectancy. Conclusions THA is the treatment of choice for femoral neck fractures in patients older than 60 years. HA should only be implanted in patients with limited life expectancy. PMID:20961437

    This is a prospective study to evaluate the efficacy of the Perkins traction in the treatment of adult femoral shaft fractures from October 1, 2007, to the present at the Black Lion Hospital in Addis Ababa University Hospital in Ethiopia. All femur fractures admitted to the hospital were reviewed and evaluated for treatment. Black Lion Hospital (Tikur Anbessa) is the university hospital in Addis Ababa and the highest tertiary teaching hospital in a country of 85 million inhabitants. A 67-bed orthopedic department offers the main ground for teaching to the undergraduate medical students. The hospital is also the pivotal center for the formation of the orthopedic residents. Patients from different parts of the country are referred to this institution for orthopedic care. A total of 68 adult (older than 16 years) patients with 69 femoral shaft fractures were considered for treatment during the study period. Consent was obtained and prospective treatment initiated. A standard Perkins traction was applied by an orthopedic team composed of consultants, orthopedic residents, physical therapists, and nurses. A protocol was developed for patients undergoing such traction. The physiotherapists will supervise all individual or group therapy sessions. Progressive knee range of motion to facilitate quadriceps and hamstring muscle strengthening exercises were implemented four times a day and recorded. Demographic information, fracture patterns, duration of traction, thigh circumference leg length discrepancy, and pin sites were routinely monitored and charted. Data were computerized and analyzed weekly, and appropriate adjustments were made accordingly. Clinical evidence of a competent callus and confirmation by radiographic studies will influence the cessation of traction to allow gait training with toe-touch crutch ambulation. Progress will be monitored during the following outpatient visits in the fracture clinic. A total of 68 consecutive patients with 69 femoral shaft

    The aim of this randomised controlled study was to compare functional and radiological outcomes between modern cemented and uncemented hydroxyapatite coated stems after one year in patients treated surgically for a fracture of the femoral neck. A total of 141 patients aged > 65 years were included. Patients were randomised to be treated with a cemented Exeter stem or an uncemented Bimetric stem. The patients were reviewed at four and 12 months. The cemented group performed better than the uncemented group for the Harris hip score (78 vs 70.7, p = 0.004) at four months and for the Short Musculoskeletal Function Assesment Questionnaire dysfunction score at four (29.8 vs 39.2, p = 0.007) and 12 months (22.3 vs 34.9, p = 0.001). The mean EQ-5D index score was better in the cemented group at four (0.68 vs 0.53, p = 0.001) and 12 months (0.75 vs 0.58, p = < 0.001) follow-up. There were nine intra-operative fractures in the uncemented group and none in the cemented group. In conclusion, our data do not support the use of an uncemented hydroxyapatite coated stem for the treatment of displaced fractures of the femoral neck in the elderly. PMID:26530648

    The purpose of this study is to compare retrospectively intraoperative fluoroscopy time and clinical-radiological results in pediatric femoral shaft fractures treated with titanium elastic nailing (TEN), with a mini-open "blind-hand" technique versus closed reduction. The study included 87 children (18 girls and 69 boys) who underwent surgical treatment with TEN for femoral shaft fractures. Patients were divided into two groups. Group 1 included 42 patients (mean age : 83 +/- 2.7 years) treated with a mini-open "blind-ha nd" technique (a 2-3 cm lateral incision at the level of the fracture ; reduction achieved with one or two fingers, without visualization of the fracture). Group 2 consisted of 45 patients (mean age: 8.8 +/- 2.6 years) treated with a closed reduction technique. Duration of surgery and intraoperative fluoroscopy time were recorded in both groups. Clinical and radiologic results were assessed using the TEN scoring system after mean follow-up periods of 213 +/- 5.8 months and 193 +/- 5.6 months in group 1 and group 2, respectively. Mean duration of surgery was 31.7 +/- 7.6 and 52.1 +/- 14.4 minutes, and mean fluoroscopy time 32.9 +/- 22.1 and 75.1 +/- 31.5 seconds in group 1 and group 2, respectively. Both surgical and fluoroscopy time were significantly longer in group 2 (p < 0.001). There was no significant difference between the two groups in terms of clinical and radiological results. All fractures healed with solid union, and there was no complication that was expected to cause permanent disability. Although successful clinical and radiological results were obtained with both techniques, duration of surgery and intraoperative fluoroscopy time were significantly higher in the closed reduction group 2. We suggest the "blind-hand" technique as an alternative to closed reduction to prevent extensive intraoperative radiation exposure and to decrease the length of the surgical procedure. PMID:21667733

    Femoral neck fractures in young adults with normal bone are mostly vertically oriented and may have variable amounts of comminution, which result from shearing forces during high-energy trauma. These factors play a role in the high rate of complications after this injury, including nonunion, malunion, failure of fixation, and avascular necrosis. These problems often occur together and inter-relate, for example, nonunion or malunion frequently result from fixation failure and varus collapse of the femoral head after reconstruction. The orthopaedic surgeon's goals of obtaining and maintaining anatomic reduction until bony union have been addressed by a number of surgical approaches and fixation constructs, however, complications are still common and no consensus exists on how these problematic fractures may be best treated. For optimal treatment of vertical femoral neck fractures, anatomic reduction must be achieved and fixation must be able to resist the high shear forces across the fracture with hip motion, weight-bearing, and muscle tone. Buttress plate fixation is a common method for stabilizing fractures that require resistance to shear forces and stands as one of the basic principles of fracture care. This technique has not been widely applied to this injury pattern. We propose that the concepts of modern fracture care should be applied together for vertical femoral neck fractures in young adults. Specifically, we propose that anatomic reduction and fixation of vertically oriented femoral neck fractures with the addition of a medial buttress plate to resist shearing forces will improve on the historically high rate of complications after these difficult injuries.

  5. Bilateral atypical insufficiency fractures of the proximal tibia and a unilateral distal femoral fracture associated with long-term intravenous bisphosphonate therapy: a case report

    PubMed Central

    2012-01-01

    Introduction Atypical insufficiency fractures of the femur in patients on long-term bisphosphonate therapy have been well described in recent literature. The majority of cases are associated with minimal or no trauma and occur in the subtrochanteric or diaphyseal region. Case presentation We describe the case of a 76-year-old British Caucasian woman who presented initially to an emergency department and then to her primary care physician with a long-standing history of bilateral knee pain after minor trauma. Plain radiographs showed subtle linear areas of sclerosis bilaterally in her proximal tibiae. Magnetic resonance imaging confirmed the presence of insufficiency fractures in these areas along with her left distal femur. There are very few reports of atypical insufficiency fractures involving the tibia in patients on long-term bisphosphonate therapy and this appears to be the only documented bilateral case involving the metaphyseal regions of the proximal tibia and distal femur. Conclusion In addition to existing literature describing atypical fractures in the proximal femur and femoral shaft, there is a need for increased awareness that these fractures can also occur in other weight-bearing areas of the skeleton. All clinicians involved in the care of patients taking long-term bisphosphonates need to be aware of the growing association between new onset lower limb pain and atypical insufficiency fractures.

    Background: Fixed angle sliding hip screw devices allow controlled impaction between the head neck fragment and the femoral shaft fragment in the surgical treatment of pertrochanteric fractures. This study was performed to evaluate the frequency and pattern of comminution at the fracture site, which may prevent the intended impaction. Materials and Methods: Three-dimensional computed tomography was used to investigate 101 pertrochanteric fractures treated with fixed angle sliding hip screw devices, with emphasis on the comminuted cortex. A comminuted fracture was defined as a fracture that had a third fracture fragment at the main fracture line. Results: There were 40 fractures without comminution and 61 with comminution. All 61 comminuted fractures had a comminuted posterior cortex, and 3 of 61 fractures also had comminution at the anterior cortex. The prevalence of cutting out of the implant from the femoral head was significantly higher in cases involving comminution at both the posterior and anterior cortices than in cases involving comminution only at the posterior cortex (66.7 % and 3.4 %, p < 0.0001). Conclusion: The posterior cortex was comminuted in 60.4% of pertrochanteric fractures and the anterior cortex in 3.0%. Intended impaction at the fracture site could not be obtained at any cortex in cases with comminution at both the anterior and posterior cortices; comminution at the anterior cortex may be a predictor of cutting out.

    In this case report, we describe a large osteochondral fracture of the anterolateral femoral condyle in an adolescent athlete while dancing. At 3 months after the misdiagnosed injury, the condylar defect was covered by a layer of disorganized fibrous tissue rich in blood vessels. To achieve good repair, an accurate curettage of the fractured surfaces, a precise reduction, and a stable internal fixation of the fragments were performed. Two poly-L-lactic acid bioabsorbable screws were used to obtain appropriate compression. At the 2-year follow-up, the patient was asymptomatic and had resumed her previous dancing activity. An MRI scan showed no interruptions of the cartilage layer at the boundary with the healthy tissue, but cartilage thinning and extensive subchondral remodeling were detected. PMID:23511583

    2015-01-01

    A 78-year-old woman developed an insufficiency fracture on her right femoral neck without trauma after four years of treatment with a bisphosphonate. Her fracture was fixed by two screws and her anti-osteoporotic drug was changed from an anti-resorptive to an anabolic agent. Seven months later, however, she sustained similar insufficiency fracture on the left femoral neck and was treated with the same method. She developed right inguinal pain again approximately eight months after her right side operation. The results of imaging tests revealed that her insufficiency fracture was converted to complete fracture, and that the fracture gap had widened as well. Her right hip was revised with hemiarthroplasty. A histological exam of the fracture site revealed evidence of decreased bone healing. Long-term administration of anti-resorptive drug prevents bone healing and remodeling and can result in atypical fractures of the femoral neck. Osteosynthesis was difficult to accomplish despite the application of proactive fixation. Therefore, more rigid fixation and careful postoperative treatment should be considered.

    Treatment of periprosthetic femur fractures after total hip arthroplasty remains a major challenge in orthopedic surgery. Recently, a novel surgical technique using intraprosthetic screw fixation has been suggested. The purpose of this study was to evaluate the influence of drilling the femoral hip stem on integrity and strength of the implant. The hypothesis was that intraprosthetic drilling and screw fixation would not cause the load limit of the prosthesis to be exceeded and that deformation would remain within the elastic limit. A sawbone model with a conventional straight hip stem was used and a Vancouver C periprosthetic fracture was created. The fracture was fixed with a nine-hole less invasive stabilization system plate with two screws drilled and inserted through the femoral hip stem. Three different finite element models were created using ANSYS software. The models increased in complexity including joint forces and stress risers from three different dimensions. A variation of drilling positions was analyzed. Due to the complexity of the physiological conditions in the human femur, the most complex finite element model provided the most realistic results. Overall, significant changes in the stresses to the prosthesis caused by the drilling procedure were observed. While the stresses at the site of the bore hole decreased, the load increased in the surrounding stem material. This effect is more pronounced and further the holes were apart, and it was found that increasing the number of holes could counteract this. The maximum load was still found to be in the area of the prosthesis neck. No stresses above the load limit of titanium alloy were detected. All deformations of the prosthesis stem remained in the elastic range. These results may indicate a potential role for intraprosthetic screw fixation in the future treatment of periprosthetic femur fractures. PMID:27272200

    This report presents a case of a displaced stress fracture of the femoral neck in an adolescent female distance runner with amenorrhea. Both reduction and internal fixation were performed early after the injury. At 24 months postoperatively, magnetic resonance imaging and bone scintigraphy showed no positive signs of femoral head necrosis and bone union was confirmed on plain X-ray. A medical examination for the presence of the signs of the female athlete triad by checking weight, calorie intake and menstrual cycles is most important to prevent such stress fractures. Athletes as well as their coaches or parents therefore need to understand female athlete triad. PMID:20205723
