Abstract
INTRODUCTION The aim of the study was to evaluate the mortality and the outcomes of femoral revision in periprosthetic femoral fractures (PFF) using a titanium modular fluted tapered stem. METHODS We retrospectively reviewed femoral revisions performed for PFF with a titanium modular fluted tapered stem in 25 patients. The average age was 74.32 years. In 21 patients the type of fracture was Vancouver B2 and type B3 in 4 cases. The mean follow-up was 29.16 (0.83-104.1) months SD ± 29.49. RESULTS The 30-day and 1-year mortality were 8% and 12% respectively. The mean value of the Charlson Comorbidity Index was 4.8 and the mean value of ASA score was 2.4. The average time to surgery from admittance was 5.45 days with 20% of patients operated on within 48 hours. A significant correlation was found between ASA score and mortality. The mean HHS was 76 points; good-excellent results were recorded in 56% of patients. 72% had no pain and 28% had slight pain (VAS 1-3). 52% of patients were able to walk without pain, limp or aids. The mean implant subsidence was 1.57 mm and superior to 5 mm in 2 cases. As complications we recorded 4 implant dislocations (16%) and 2 infections. Reoperation rate was 12%. CONCLUSIONS Femoral revision with a modular fluted tapered stem in patients with periprosthetic fractures results in good clinical and radiological outcomes. However, mortality remains high and, despite the modularity design, dislocation is the most frequent complication.

Abstract
Successful treatment of periprosthetic femur fractures, like all fractures, requires careful attention to understand the fracture pattern nuances, identifying and executing a rational treatment approach, and providing an appropriate postoperative recovery protocol. Unlike most other fractures, modification of standard techniques is often required to obtain a stable fixation construct, and there is a greater role for revision arthroplasty in the treatment of periprosthetic fractures. Optimal indications for surgical repair versus revision arthroplasty and optimal postoperative weight-bearing protocols remain uncertain. Reported outcomes for patients with periprosthetic femoral shaft fractures are generally good and are relatively consistent. Results for periprosthetic distal femur fractures, however, are less good and more inconsistent. Both periprosthetic femoral shaft and distal femur fractures are associated with relatively high mortality rates, approaching that of patients with hip fractures. This review should provide insight into the current solutions and challenges for the treatment of patients with periprosthetic femur fractures.

Abstract
We are currently facing an epidemic of periprosthetic fractures around the hip. They may occur either during surgery or post-operatively. Although the acetabulum may be involved, the femur is most commonly affected. We are being presented with new, difficult fracture patterns around cemented and cementless implants, and we face the challenge of an elderly population who may have grossly deficient bone and may struggle to rehabilitate after such injuries. The correct surgical management of these fractures is challenging. This article will review the current choices of implants and techniques available to deal with periprosthetic fractures of the femur.

Abstract
The incidence of periprosthetic fractures has been reported to be between 1 and 20.9% and appears to be on the rise. Fractures that occur around the femoral stem, particularly when the stem is loose or there is a loss of bone stock pose a technical challenge. These are rare injuries and there is considerable debate regarding their optimal treatment. Reconstruction with large segment endoprosthetic replacement is an acceptable solution for elderly patients who have limited functional demands and where the prosthesis is expected to outlive the patient. The younger patient poses a much greater challenge, the bone must be reconstituted and the femoral canal geometry must sufficiently restored to allow the stable insertion of a prosthesis. There are very few techniques that exist in this scenario. One such technique is impaction bone grafting and revision to a long smooth tapered cemented stem. This allows the restoration of bone stock and the stable insertion of a prosthesis. The aim of this article is to discuss the theory behind impaction bone grafting, the technical aspects and challenges of this technique, including fracture reduction methods, and to appraise all the literature available on impaction bone grafting for periprosthetic fractures.

Abstract
The development of periprosthetic fractures around loose femoral components can be a devastating event for patients who have undergone total hip arthroplasty (THA). As indications for THA expand in an aging population and to use in younger patients, these fractures are increasing in incidence. This review covers the epidemiology, risk factors, prevention, and clinical management of periprosthetic femoral fractures. Treatment principles and reconstructive options are discussed, along with outcomes and complications. Femoral revision with a long-stem prosthesis or a modular tapered stem is the mainstay of treatment and has demonstrated good outcomes in the literature. Other reconstruction options are available, depending on bone quality. Surgeons must have a sound understanding of the diagnosis and treatment of periprosthetic femoral fractures.

Abstract
BACKGROUND Healing and functional recovery have been reported using an extensively porous-coated stem in Vancouver B2 and B3 periprosthetic fractures; however, loss of cortical bone has been observed when using these stems in revision surgery for aseptic loosening. However, it is unclear whether this bone loss influences subsequent loosening. QUESTION/PURPOSES We analyze the healing fracture rate and whether the radiographic changes observed around and extensively porous-coated stem used for periprosthetic fractures affect function or loosening. METHODS We retrospectively reviewed 35 patients with periprosthetic fractures (20 Vancouver B2 and 15 Vancouver B3). Patients' mean age at surgery was 80 years (range, 51-86 years). No cortical struts were used in this series. We evaluated radiographs for signs of loosening or subsidence. The cortical index and the femoral cortical width were measured at different levels on the immediate pre- and postoperative radiographs and at different periods of followup. The minimum followup was 3 years (mean, 8.3 years; range, 3-17 years). RESULTS All fractures had healed, and all stems were clinically and radiographically stable at the end of followup. Nineteen hips showed nonprogressive radiographic subsidence during the first 3 postoperative months without clinical consequences. The cortical index and the lateral and medial cortical thickness increased over time. Increase of femoral cortex thicknesses was greater in cases with moderate preoperative osteoporosis and in cases with stems less than 16 mm in thickness. CONCLUSIONS Our data suggest an extensively porous-coated stem for Vancouver B2 and B3 periprosthetic fractures leads to a high rate of union and stable fixation. Cortical index and lateral cortex thickness increased in these patients with periprosthetic fractures. Patients with moderate osteoporosis and those using thin stems showed a major increase in femoral cortex thickness over time.

Abstract
OBJECTIVES The purpose of the present study was to analyze the retrospective clinical and radiographic results of femoral revision arthroplasties with impaction bone grafting performed by experienced Japanese surgeons. PATIENTS AND METHODS We investigated the radiographic and clinical records more than 2 years after the surgery in 99 hips of 93 patients. The average age was 66.3 years (36-84 years) and the average follow-up period was 5.2 years (2-13 years). The Merle d'Aubigné and Postel hip score was used for clinical assessment, and peri-operative fractures were recorded. The survival curve was estimated using Kaplan-Meier method. RESULTS The mean Merle d'Aubigné and Postel hip score improved from 9.0 points to 15.2 points at the final follow-up. Augmentations for segmental defect of femoral cortices were undertaken in 55 hips. Metal or strut allograft plates were applied to 9 hips and 21 hips, respectively. Intra-operative fractures or perforations occurred in 20 hips. Re-operations of the femur were undertaken in nine hips including five post-operative femoral fractures. More than 5 mm of subsidence was observed in only 2 hips. The survival rates at 8 years after the operation were 94.8 % with femoral fractures as the end point, 93.1 % with any stem removal or exchange as the end point, and 99.0 % with aseptic stem loosening as the end point, respectively. CONCLUSION The present study showed encouraging mid-term results of impaction bone grafting for femoral revision arthroplasty by experienced surgeons in Japan. Aggressive augmentation of segmental defects and attenuated femoral shafts prevents massive stem subsidence and periprosthetic fracture.

Abstract
Capacious diaphyses and poor bone stock in revision arthroplasty can lead to fracture and poor component fixation. Impaction bone grafting can be performed in salvage reconstructions in cases with extensive circumferential bone loss. We present a consecutive series of patients who underwent proximal or distal femoral reconstructions in combination with impaction bone grafting. The average age was 62 years, and the mean follow-up was 36 months (range, 24-84). No revisions were performed for mechanical failure, and radiographs revealed no evidence of implant loosening. No patient complained of end-of-stem thigh pain. There were 3 failures: 1 for periprosthetic fracture, 1 for instability, and 1 for infection. Impaction bone grafting can be used in combination with proximal and distal femoral arthroplasty to successfully manage cases with extensive bone loss after failed hip and knee arthroplasty. The procedure reconstitutes necessary bone stock, improves stress shielding, and provides immediate fixation in capacious canals.
