Osteonecrosis of the hip accounts for about 10% of all total hip arthroplasty cases and presents a significant challenge for those patients with and without femoral head collapse. Subtrochanteric femur fractures have been reported with numerous types of proximal femoral implants. Care must be taken to avoid penetrating the lateral cortex of the proximal femur inferior to the distal border of the lesser trochanter. Core decompression requires a 3 mm to 20 mm defect in the lateral femoral cortex. Subtrochanteric femur fractures are a well-known complication of core decompression as well. We present a case of a subtrochanteric fracture following the removal of a porous tantalum implant.

Introduction: Total hip arthroplasty (THA) after proximal femoral fixation is a challenging procedure due to possible hardware-related complications. Case presentation: A 78-year-old female with hip osteoarthritis had a proximal femoral osteotomy fixed using a blade plate in the same femur 41 years ago. A two-step approach was planned. After a challenging hardware removal, an iatrogenic subtrochanteric fracture below the degenerated hip occurred after three months. THA with a tapered long stem was successfully performed with no need for additional osteosynthesis, and good results were seen two years later. Discussion: THAs in subtrochanteric fractures are technically demanding but feasible in selected cases. Hardware removal before THA implantation may carry important risks, and the surgical team should be prepared to perform arthroplasty in case of complications. Conclusion: THA in a subtrochanteric fracture below hip osteoarthritis is a feasible option in selected cases.

We report a 68-year-old end-stage renal disease female patient on dialysis for 15 years. She sustained consecutive fractures starting with left-sided femoral neck fracture, followed 16 months later by a right-sided one. On her recovery from her right hip injury she sustained a stress type subtrochanteric fracture at the entry site of the fixation implants and an ipsilateral humeral shaft fracture. Cementless total hip replacement was done for the left femoral neck, and osteosynthesis was done for her undisplaced right femoral neck fracture. Revision fixation was done for her right subtrochanteric fracture with a long Gamma nail that was statically locked. The humeral fracture was fixed with an interlocking nail in a closed manner. This case highlights the fact that sequential hip fractures is an ominous event which is likely to be followed by a quick cascade of bone injuries with trivial trauma and a high rate of unexpected complications. Our treatment approach is explained here, stressing the unexpected complications and challenges met.

In the United States, more than 300,000 hip fractures occur annually in the elderly population with associated significant morbidity and mortality. Both intracapsular and extracapsular hip fractures have inherent treatment challenges and therefore are at risk of nonunion complications. A systematic assessment including radiographic, metabolic, and infectious evaluations should be completed for all patients suspected of nonunion. Failed internal fixation of intracapsular hip fractures is typically treated with arthroplasty, while extracapsular proximal femur nonunions may be amenable to revision internal fixation or arthroplasty. While not a classic hip fracture, bisphosphate associated subtrochanteric femur fractures affect a similar patient population and are historically difficult to treat. Atypical subtrochanteric femur fractures are at increased risk of nonunion given the altered biologic environment secondary to bisphosphonate use; therefore adjuvant therapies may be beneficial in setting of revision fixation. Having a thorough understanding of nonunion risks, recognition, evaluation, and treatment is necessary for appropriate patient care.

This case report involves a 56-year-old female (Mrs X) with a traumatic intertrochanteric hip fracture with subtrochanteric extension below a previous Birmingham hip resurfacing. Periprosthetic fractures following hip resurfacing are usually subcapital and treated with a revision or conservative management. We present an unusual surgical problem with an interesting solution stabilising the fracture using a proximal femoral locking compression plate (LCP). Eight months following surgery the patient is able to walk pain free and there is good fixation and stability.

Introduction: The Comminuted trochanteric and subtrochanteric femoral fractures are considered as one of the most difficult fractures to treat in the orthopaedic surgery and they associated with high incidence of nonunion, malunion. Various implants, both intramedullary and extramedullary, are available for their fixation.Objective: To assess the success rate of proximal femoral locking compression plate osteosynthesis in comminuted trochanteric and subtrochanteric femoral fracture in lateral decubitus approach without per operative image intensifier.Method: 20 consecutive patients with comminuted Trochanteric and subtrochanteric fractures were operated upon with PF-LCP. Detailed clinical conditions of all patients, duration of operation, technical difficulty with the implant, hospital stay period were recorded. Patients were visited at 6 weeks interval till union then 3 monthly. The Harris Hip Score was used to document hip function at final follow-up.Result: There were fifteen excellent (75%), two good (10%), two fair (10%) and one poor (5%) results according to Harris hip score. No instance of implant failure was recorded.Conclusion: Fixation of comminuted subtrochanteric fractures with PF-LCP in lateral decubitus approach without per operative image intensifier provides stable fixation with high union rate and fewer complications.J Dhaka Medical College, Vol. 23, No.2, October, 2014, Page 179-185

The authors describe the case of a 51-year-old woman with an osteonecrosis of her right femoral head after treatment of an atypical subtrochanteric fracture caused by pycnodysostosis. She had this fracture after a low-trauma fall. She was of short stature with typical facial features, short stubby hands, and radiological features including open cranial sutures, obtuse mandible, and generalized skeletal sclerosis. The majority of cases of atypical subtrochanteric fractures are associated with long-term use of bisphosphonates; some occur in bisphosphonate-free patients. We report a rare case of total hip arthroplasty (THA) in a patient with pycnodysostosis who developed an osteonecrosis of the femoral head after treatment of an atypical subtrochanteric femoral fracture. We performed cementless THA in combination with a plate and cables. Cementless THA is a potential intervention in a patient with pycnodysostosis; although the bone quality may have been sclerotic, healing is not a problem in this condition.

Aims The aim of this study was to evaluate the outcomes of a salvage procedure using a 95° angled blade plate for failed osteosynthesis of atypical subtrochanteric femoral fractures associated with the long-term use of bisphosphonates. These were compared with those for failed osteosynthesis of subtrochanteric fractures not associated with bisphosphonate treatment. Patients and Methods Between October 2008 and July 2016, 14 patients with failed osteosynthesis of an atypical subtrochanteric femoral fracture were treated with a blade plate (atypical group). Their mean age was 67.8 years (60 to 74); all were female. During the same period, 21 patients with failed osteosynthesis of a typical subtrochanteric fracture underwent restabilization using a blade plate (typical group). Outcome variables included the time of union, postoperative complications, Harris Hip Score, and Sanders functional rating scale. Results In the atypical group, union was achieved in 12 patients (85.7%) at a mean of 8.4 months (4 to 12). The mean follow-up was 31.2 months (12 to 92) The plate broke in one patient requiring further stabilization with a longer plate and strut-allograft. Another patient with failure of fixation and varus angulation at the fracture site declined further surgery. In the typical group, union was achieved in 18 patients (85.7%) at a mean of 7.9 months (4 to 12). There was no difference in the mean Harris Hip Score between the two groups (83.1 points vs 86.8 points; p = 0.522) at the time of final follow-up. Sanders functional rating scores were good or excellent in 78.6% of the atypical group and in 81.0% of the typical group. Conclusion The 95° angled blade plate was shown to be an effective fixation modality for nonunion of atypical subtrochanteric fractures with a high rate of union and functional improvement, comparable to those after fractures not associated with bisphosphonate treatment.

Abstract The purposes of the present research were (1) to analyse and characterize the hip fractures treated at Oulu University Hospital during a one-year period using the special forms of the Standardized Audit of Hip Fractures in Europe (SAHFE) and to evaluate their value for quality control, (2) to compare gamma nail (GN) and dynamic hip screw (DHS) fixation for the treatment of trochanteric hip fractures, focusing especially on the functional aspects, (3) to compare the short-term outcome of gamma nail (GN) and dynamic hip screw (DHS) fixation for the treatment of subtrochanteric hip fractures, and (4) to examine the rate and reliability of the classification of basicervical hip fractures and the outcome of the operative methods used for their treatment. Oulu University Hospital joined the Swedish Hip Fracture Project (Rikshöft), aimed at developing the quality control of hip fracture treatment, in 1989, and this later evolved into a project called the Standardized Audit of Hip Fractures in Europe (SAHFE), funded by the European Commission. Registration of hip fractures on the SAHFE forms was common practise in Oulu from 1st September 1997 until the end of December 2003. SAHFE data collection forms were used in all four studies belonging to this thesis. There were 238 hip fracture patients during the one-year period of registration at Oulu University Hospital. The intracapsular / extracapsular fracture rate (60/40) and the female/male rate (80/20) seemed to be similar to those reported in the recent Finnish Health Care Register data. The most frequent method for treating cervical fractures was Austin-Moore hemiarthroplasty (68%) and that for trochanteric and subtrochanteric fractures GN fixation (86%). The SAHFE forms proved to be easy to use and practicable for evaluating the quality of hip fracture treatment. In a matched-pair study the short-term outcomes of the treatment of trochanteric fractures (after 4 months) were slightly better in the DHS group than in the GN group with respect to walking ability and mortality. The difference in mortality was at least partly due to the higher number of complications requiring re-operations associated with GN fixation. In the treatment of subtrochanteric hip fractures, there were four intraoperative complications (9.3%) in the GN group but none in the DHS group. On the other hand, postoperative complications were more common in the DHS group (20% vs. 2%). It is significant that all these complications in the DHS group occurred in Seinsheimer type IIIA fractures. It is concluded that, despite the perioperative problems associated with gamma nailing, this technique may be preferable to DHS fixation for specific fracture types with medial cortical comminutation, such as Seinsheimer type IIIA. Altogether 108 of the 1624 hip fractures were initially classified by the surgeons as basicervical fractures, but after a careful second look only 30 fulfilled all the criteria. The definitive rate of basicervical fractures was thus 1.8%. Treatment of basicervical fractures as trochanteric fractures proved superior to their treatment as cervical fractures, resulting in lower re-operation rates. In conclusions; this thesis suggests that SAHFE forms are very useful for evaluating the quality of hip fracture treatment. Both GN fixation and DHS fixation are effective methods for the treatment of trochanteric hip fractures in elderly patients; in less comminuted fractures, the DHS method is the preferred method of treatment whereas GN fixation is alternative treatment for more comminuted fractures. GN fixation is preferable for the subtrochanteric fratures. Basicervical fractures shoud be regarded clinically as extracapsular fractures and managed in a similar manner to trochanteric fractures.

♦ Traction is not useful for trochanteric fractures♦ Surgery should not be delayed unless the medical condition of the patient can be improved♦ Dynamic implants are best (sliding hip screw best)♦ Early full weight bearing should be achieved♦ Most patients return to their own home.
