Which side should be taken care of when positioning a lag screw in intertrochanteric femoral fracture: right or left?

Purpose: We aimed to demonstrate which side should be taken care of when fixating an intramedullary nail with a lag screw for an intertrochanteric fracture under the influence of clockwise torque.

Methods: From 2021 to 2023, 63 patients who underwent surgery for intertrochanteric fractures were divided into two groups: Group A (45 patients with left-side fractures) and Group B (18 patients with right-side fractures). We evaluated intraoperative images before fixation and postoperative radiographs to assess anteromedial cortical support.

Early unexpected failure of a vitamin E-infused highly cross-linked polyethylene liner: A case report.

Rationale: Total hip arthroplasty (THA) with a polyethylene (PE) liner is 1 of the most effective and successful treatment strategies for end-stage hip disorders. Vitamin E-infused highly cross-linked polyethylene is theoretically known to prevent failure due to oxidative degradation in the body, and is resistant to wear; therefore, successful long-term survival of THA is expected.
