Traumatic osteonecrosis of the femoral head (TONFH) refers to ischemic osteonecrosis is resulting from an acute mechanical interruption of the blood supply to the femoral head. The early diagnosis and optimal treatment have been central focuses of research and continue to undergo improvement. Reliable animal models are essential for advancing research into the treatment of the disease.

Background: Pediatric femoral neck fractures (PFNF) are rare but associated with a high rate of serious complications such as avascular femoral head necrosis (AVN). Major risk factors and prognostic tools for an AVN are still unclear. As AVN is a devastating complication, this study aims to evaluate the predictors for AVN following a PFNF.

Orthop Surg
January 2025
Department of Orthopedic Surgery, The General Hospital of the People's Liberation Army, Beijing, China.
Objective: Determining the optimal osteotomy length for patients with unilateral Crowe-IV developmental dysplasia of the hip undergoing subtrochanteric osteotomy remains challenging due to the significant variability in pelvic and spinal alignment. Incorrect osteotomy length, compounded by pelvic or spinal tilt, can adversely affect postoperative gait and long-term outcomes. Therefore, this study could introduce a method to calculate the osteotomy length for patients with unilateral Crowe-IV developmental dysplasia of the hip, correcting spinal and pelvic tilt, and improving patient gait.

Background: Use of jumbo femoral heads (≥ 40 mm) in total hip arthroplasty (THA) decreases postoperative dislocation, however, may leave patients more susceptible to groin pain. Limited data exist for the effect of jumbo femoral heads and acetabular cup position on modern patient-reported outcome measures (PROMs). This study evaluated the effect of jumbo femoral heads and acetabular cup position on PROMs after primary THA.
