Concurrent ipsilateral fractures of the hip and femoral shaft:A meta-analysis of 659 cases

659 cases of concurrent, ipsilateral fractures in the hip and femoral shaft reported in 59 studies were analyzed. The causes were a road traffic accident in 78% and other types of high-energy traumas in 13% of the patients. This injury combination was rare in children. The median age was 34 years. 78% of the patients were men. One-third had multiple injuries, one-half had injuries of the ipsilateral knee and one-half had other lower limb injuries. The femoral neck fractures were most often basilar and the reported rate of avascular necrosis was 3%. The trochanteric fractures were intertrochanteric transverse, and seldom comminuted. The important factors in reducing morbidity were an early diagnosis of all injuries and efficient treatment of the shaft fractures. Locked intramedullary nails yielded results which were superior to combinations of plates or unlocked nails and separate hip screws. Reconstruction nails (cephalomedullary nails) gave results equal to those of customary locked nails and separate hip screws. The rate of healing of the hip fracture was over 99%, the treatment of the shaft fracture being of main importance for the outcome.

A new classification and treatment protocol for combined fractures of the femoral shaft with the proximal or distal femur with closed locked intramedullary nailing: clinical experience of 63 fractures

The medical records and radiographs of 63 patients, who were admitted between 1989-1997, with a combined femur fracture, were reviewed. Associated injuries were present in 38 (60%) patients. The combined fractures were classified into four major types depending on their anatomical position: type I, femoral shaft fracture combined with hip neck fracture; type II, femoral shaft fracture combined with a trochanteric fracture; type III, femoral shaft fracture combined with a distal femur fracture; and type IV, femoral shaft fracture combined with a proximal or distal femur fracture. The fractures were treated with locked intramedullary nailing and additional free cancellous 6.5-mm screws as needed. Fifty-six fractures healed without further operations. Of the remaining 6 fractures, 2 were material failures, 1 malunion with 3-cm shortening and external rotation of the femoral diaphysis, 2 early infections of the surgical wound, and 1 pseudarthrosis of the femoral shaft. All fractures were healed between 16 and 32 weeks (average: 20 weeks).     

Management of pediatric femoral shaft fractures

Femoral shaft fractures are the most common major pediatric injuries managed by the orthopaedic surgeon. Management is influenced by associated injuries or multiple trauma, fracture personality, age, family issues, and cost. In addition, child abuse should be considered in a young child with a femoral fracture. Nonsurgical management, usually with early spica cast application, is preferred in younger children. Surgery is common for the school-age child and for patients with high-energy trauma. In the older child, traction followed by casting, external fixation, flexible intramedullary nails, and plate fixation have specific indications. The skeletally mature teenager is treated with rigid intramedullary fixation. Potential complications of treatment include shortening, angular and rotational deformity, delayed union, nonunion, compartment syndrome, overgrowth, infection, skin problems, and scarring. Risks of surgical management include refracture after external fixator or plate removal, osteonecrosis after rigid antegrade intramedullary nail fixation, and soft-tissue irritation caused by the ends of flexible nails.

Outcome of intramedullary nail for fixation of osteoporotic femoral shaft fractures in the elderly above 60

IntroductionIntramedullary nailing is an acceptable treatment option for femoral shaft fracture in young patients but not extensively studied in the elderly with osteoporotic fractures. Plate fixation for osteoporotic femoral shaft fractures have a high rate of complications and delayed healing time, and the most acceptable treatment is intramedullary nailing. This study evaluated the healing time and incidence of complications in osteoporotic femoral shaft fractures after intramedullary nailing.Patients &MethodsThis was a retrospective study that included 16 patients above 60 years old with osteoporotic femoral shaft fractures operated between January 2015 and December 2018. Patients with metastatic fractures or with atypical fractures were excluded. Thirteen patients had low-energy injuries such as a simple fall from standing height or lower and twisting injuries. The remaining 3 patients sustained high-energy-mechanism of injury. No patient received bisphosphonate except 2 patients received oral bisphosphonate for a period of 6 and 8 months, respectively.ResultsSixteen patients (12 females and 4 males) with mean age 69.5 ± 3.7 presented with femoral shaft fracture were operated with intramedullary nail, 10 patients were fixed with trochanteric entry nails with proximal neck screws, and 6 patients were fixed with piriformis entry nails. In 9 patients, closed reduction of fracture was achieved while 7 patients required open reduction, of which 5 fracture required cerclage wire addition. The mean bone healing time was 5.35±1.2 months. Intraoperative extension of femoral fractures during intramedullary nail insertion was observed in two cases that required open reduction and addition of cerclage wires around the fracture. The overall incidence of complications was 18.7%.ConclusionsIntramedullary nailing for osteoporotic femoral shaft fracture is a good acceptable option in elderly patients with reasonable healing time with no major complications.     

Management of fractures and fracture complications of femoral shaft using the ASIF compression plate.

Nnieteen acute fractures and fourteen fracture complications of the femoral shaft were managed with ASIF plate fixation. Two patients having femoral shortening procedures were similarly managed. Most injuries involved the distal femoral shaft, and were judged unacceptable for intramedullary nailing. Single plate fixation and immediate mobilization of the knee joint were possible in most patients. Technical failure, refracture through an end-screw hole, or nonunion occurred in 20% of the injuries. Plate fixation of the femoral shaft is not the surgical procedure of choice for management of femoral shaft injuries. It is an acceptable alternative to intramedullary nailing but carries a higher risk of complication.     

Comparison of compression plate and flexible intramedullary nail fixation in pediatric femoral shaft fractures

The purpose of this study was to compare the results of compression plating and flexible intramedullary nailing for pediatric femoral shaft fractures. Thirty-eight consecutive patients with 40 femoral shaft fractures were evaluated. Twenty-two femoral segments were treated with a compression plate and 18 femoral segments were treated with flexible intramedullary nailing. The time to healing, operation time and complications were evaluated. The average operation time was statistically significantly shorter in the nailing group (P=0.039). Four implant failures occurred in the compression plate group whereas one non-union was observed in the flexible nailing group. Flexible intramedullary nailing seems to provide a high union rate with a shorter operation time when compared with plate fixation.     

Clinical outcomes and affecting factors of ipsilateral femoral neck and shaft fractures - Multination,multicenter analysis

BackgroundThis study aimed to evaluate the clinical outcomes of ipsilateral femoral neck and shaft fractures and identify the risk factors associated with missed diagnosis of femoral neck fractures and clinical outcomes of this fracture.MethodsThe ipsilateral femoral neck and shaft fractures from seven centers were retrospectively reviewed. Data on injury mechanism, fracture pattern, and fracture classification; surgical factors including fixation method; and timing of detection of femoral neck fracture were analyzed. The clinical outcomes, complications, and the incidence of avascular necrosis of the femoral head (AVNFH) were reviewed. Risk factors for missed femoral neck fracture and complications were analyzed.ResultsIn total, 74 patients with an average age of 43.6 years were included. Of the femoral shaft fractures, 56.8% were type A, 21.6% were type B, and 21.6% were type C. Sixteen patients had an open fracture of the femoral shaft. Femoral neck fracture was initially missed in 27% patients and the timing of delayed diagnosis was at an average of 11.1 days after injury. For detecting femoral neck fractures, minimal displacement of the femoral neck fracture was a risk factor, whereas computed tomography (CT) was a protective factor. The incidence of AVNFH was 6.8% at an average of 36.8 months after injury. The AVNFH group had more displaced femoral neck fractures at the time of surgery, but there was no difference in the timing of diagnosis compared to non-AVNFH group. The femoral shaft showed considerable healing problems, with an average union time of 29.7 weeks and a 20.2% nonunion rate.ConclusionIpsilateral femoral neck and shaft fractures had a high rate of missed diagnosis, especially in minimally displaced fractures; however, CT was a protective factor. AVNFH occurred in 6.8% and was related to femoral neck fracture displacement, but not delayed diagnosis. The femur nonunion rate was high, which warrants attention.     

Results of operative therapy of periprosthetic femur shaft fractures in total hip endoprostheses

Periprosthetic femoral shaft fracture represents an uncommon but potentially devastating complication associated with total hip arthroplasty. The treatment should result in complete union of the fracture and at the same time guarantee stability of the implant. 15 patients treated between 1992 to 1998 were analysed. Clinical and radiographic follow-up averaged 30 months (6-79 months) in 13 cases. Two patients died regardless of the fracture. The method of treatment depended on the intraoperative stability of the prosthesis and in addition on the fracture type (Bethea). In 5 cases of intraoperative stability of the prosthesis plate fixation was performed. Plate fixation was complicated by fixation failure combined with a recurrent fracture in two cases leading to shift to a long stem prosthesis. Ten cases of fractures associated with loose stems were treated with a new prosthesis using a long stem system. In these cases an uncomplicated healing of the fracture was achieved with adequate stability in radiographic examinations. The average Harris score was 70 (26-93). For fractures near the femoral stem or in case of implant loosening we recommend the shift to a long stem prosthesis. Also in fractures distally from the femoral stem tip we prefer now long stem implants rather than plate fixation to avoid large exposure of the femoral shaft and resultant complications.

Indication and technic of interlocking nailing of the femur

Between 1973 and 1982 we treated 569 fractures of the femoral shaft by means of osteosynthesis. The internal nailing was performed in 41.6%. We used an interlocking nailing in 170 cases, 116 times statically and 54 times dynamically. An open reposition was performed in 48.2%. With only a very small incision we exposed the area of the fracture to insert the reamer guide under control of the fingers into the distal part of the femoral shaft. By using this technique there is no danger of disposing the fragments in order to achieve stabilisation in the correct position. 52.4% of the patients were younger than 30 years and 25.9% older than 30 years and 25.9% older than 60 years. In all cases we observed an osseous healing, twice a secondary cancellous bone craft was necessary. As complications we had an infection rate of 2.9%, loosening of the bolt in 0.6%, axial malalignment greater than 10 degrees in 0.6%, a rotary malalignment greater than 10 degrees in 1.2%. We did not observe any refracture. Less complications can be observed in interlocking nailing in comparison with plate osteosynthesis. Technique, indication, mistakes, and dangers as well as careful timing of operation are discussed. In open fractures delayed osteosynthesis by means of interlocking nailing is to be preferred to primary plate osteosynthesis. Fractures fixed by interlocking nailing had comparatively less complications in fracture healing and especially no more shortenings and rotation deformities, but the advantage of early full weightbearing. The interlocking nail has a very important value in the management of femoral shaft fractures.

Treatment of fractures of the femoral shaft with early cast bracing

This study describes experience in the treatment of fractures of the femoral shaft by early weight bearing in a cast brace, at Glasgow Royal Infirmary. During 1977–1979, 117 fractures of the femoral shaft were treated. The average time for fracture healing was 15 weeks and 96 per cent of the fractures had overall satisfactory results.     

Legg–Calvé–Perthes disease following Ender nail fixation of a pediatric femoral fracture

Introduction and importanceLegg–Calvé–Perthes disease (LCPD) sometimes occur in children, however it is difficult to diagnose it at the early stage especially in the cases there are no complaints of symptoms. Femoral shaft fractures in children cause various complications such as leg-length discrepancy, nonunion and malunion, refracture, and osteonecrosis of the femoral head. We presented a rare case in which a pediatric patient developed LCPD after femoral shaft fracture.Case presentationA healthy 8-year-old boy sustained a left femoral diaphyseal fracture following a pedestrian car accident. Fixation was achieved using retrograde Ender nails; bone union was confirmed at 3 months postoperatively, and the Ender nails were removed at 8 months postoperatively without any problems. Unfortunately, the morphological change of the ipsilateral femoral head and subtle symptoms were missed until the femoral head collapsed. LCPD was successfully treated with intertrochanteric varus osteotomy, which achieved a good clinical result.Clinical discussionAlthough the reason for the ipsilateral LCPD after the femoral shaft fracture is unclear, this case highlights the need for close postoperative follow-up of pediatric femoral fractures resulting from high-energy trauma to prevent the misdiagnosis of this coincidental complication.ConclusionThis case report describes a missed ipsilateral LCPD after a femoral diaphyseal fracture caused by high-energy trauma. Close postoperative follow-up with a detailed assessment and vigilant interpretation of postoperative radiography is imperative to avoid delayed/missed diagnosis of conditions for which early management may provide better outcomes.     

The use of Ender nails in femoral shaft fractures: what are the remaining indications?

The use of Ender nails for the treatment of femoral shaft fractures has been described as technically easier and less time consuming than current intramedullary nailing techniques. We reviewed our results with unlocked Ender nails in 26 stable and 17 unstable fracture patterns an average of 3-4 years after injury. Because of continued instability, 42% of the stable and 76% of the unstable groups required adjunctive stabilization in the form of skeletal traction, a cast, or an external fixator. Additionally, nail migration and shortening and loss of motion at the knee were seen in 14 fractures in each group. Although two thirds of the patients with stable fracture patterns obtained good or excellent results, no outcome in the unstable group was rated excellent and only 19% were considered good. We therefore recommend that rigid locked intramedullary nails be used in femoral diaphyseal injuries. The use of Ender nails should be limited to stable fracture patterns and locked with screws or wires. They may be particularly useful for fractures in femora with small medullary canals (less than or equal to 8 mm), fractures below noncemented femoral prostheses, and fractures in young children requiring intramedullary stabilization without injuring the physeal plates.     

The influence of fracture etiology and type on fracture healing: a review of 104 consecutive tibial shaft fractures

This study was conducted to determine retrospectively the factors which influence fracture healing and risk for nonunion in patients with tibial shaft fractures. One hundred consecutive patients with 104 tibial shaft fractures and a mean age of 40 (14-85) years were reviewed. Fractures were classified according to the AO classification system. There were 22 open fractures and 52 comminuted fractures. Thirty-eight fractures were caused by high-energy trauma. Fracture pattern, soft-tissue condition, level of energy of the trauma, malalignment, and treatment methods were identified. The influence of these factors on the time of hospital stay and sick-leave, delayed union, and nonunion were calculated. Normal healing occurred in 61 fractures with a mean healing time of 17 weeks, delayed union in 27 with a mean of 35 weeks, and nonunion in 16 with a mean of 69 weeks. The relative risk of developing nonunion in open fractures was 8.2 (CI = 2.9-10.5) and 2.9 (CI = 1.2-3.2) in fractures exposed to high-energy trauma. This study showed that the soft-tissue condition and level of trauma energy are good predictors for the development of complications. Considering these risk factors at an early stage in the planning of treatment might reduce the risk of nonunion. ergy level of the trauma, fracture comminution, initial fracture displacement, treatment method, contamination, and associated injuries will influence fracture healing. Conservative treatment has in general been recommended for undisplaced closed or grade I open fractures caused by low-energy trauma [15, 18, 21]. However, conservative treatment of a tibial shaft fracture means immobilization of the lower leg for a long period of time, especially if healing is delayed. Thus, it is important to consider the risk of healing complications when planning the appropriate treatment method in the early stage after the injury. The purpose of this study was to analyze complications such as delayed union and nonunion and to identify factors which affect the healing of tibial shaft fractures.     

Experience in the use of the long Gamma nail for 16 femoral shaft fracture that have occurred following initial Asian Pacific Gamma nail fixation for pertrochanteric fractures

From January 1993 to September 2002, 931 patients suffered from intertrochanteric fracture and subrochanteric fracture received open reduction and internal fixation with APGN in our institute. Among these patients, 16 patients (1.7%) developed a femoral shaft fracture after the initial fixation with APGN. Removal of the APGN, closed reduction and fixation with long Gamma nail (LGN) was performed in all the 16 patients. The patients were followed for 12-60 months (average, 39.8 months). The union time of fracture was 12-24 weeks (average, 18.5 weeks) for femoral shaft fractures and 12-20 weeks (average, 16 weeks) for peritrochanteric fractures. Two early complications were noted, including one superficial (6%) infection and one deep (6%) infection. Two malunions (12.5%) developed with no definite functional impairment. The functional results using the Harris hip score were good to excellent. In conclusion, closed reduction and internal fixation with a LGN is very effective in the management of a femoral shaft fracture, a complication of a previous APGN that had been initially used for stabilisation of a pertrochanteric fracture.
