Locked plate (LP) and retrograde intramedullary nail (RIN) are the most commonly used treatment options for periprosthetic femur fracture above total knee arthroplasty (TKA). Controversy still exists regarding which is better. Therefore we performed a meta-analysis to compare their clinical results. ⋯ This meta-analysis found no statistically significant difference in six month union rate, union time, operation time and complication rate between the LP group and RIN group. The RIN fixation may have a potential of lower re-operation rate compared with LP. The mean union time was 4.0 months in the LP group and 3.7 months in the RIN group.

Lateral femoral cutaneous nerve injury with the direct anterior approach for total hip arthroplasty.
Although injury of the lateral femoral cutaneous nerve (LFCN) is a known complication after total hip arthroplasty (THA) via the direct anterior approach (DAA), the impact of this complication on postoperative quality of life (QOL) is unclear. This study aims to investigate the incidence of LFCN injury after DAA for THA, and to determine the impact of LFCN injury on QOL and hip function. ⋯ The incidence of LFCN injury decreased QOL but not hip function after DAA for THA.

The purpose of this study was to analyse the incidence of interprosthetic femoral fractures and describe risk factors for them. ⋯ Identifying risk factors for this specific type of fracture may facilitate their prevention. Better implant stability and the presence of a gap between stems in a lower canal zone appear to hinder the occurrence of interprosthetic fractures.

Failure of proximal femoral fracture managed by proximal femoral nail (PFN) leads to a very difficult situation to handle with conventional techniques, and reversed distal femoral locking compression plate (DF-LCP) is of great benefit in these selective cases. ⋯ We conclude that DF-LCP is a potential and safe implant of choice for the management of nonunion associated with failed PFN. It may be considered an implant of choice as rescue from such a complex situation. It offers several anatomical, biomechanical and clinical advantages over other available conventional implants.
