Clinical Outcomes of DAMIS Traction Table-Assisted Anterior Approach versus Posterolateral Approach on Total Hip Arthroplasty in the Treatment of Femoral Head Necrosis.

Aim: Femoral head necrosis often leads to hip joint dysfunction, which can be effectively treated with total hip arthroplasty (THA). This study compares the clinical outcomes of direct anterior minimally invasive surgery (DAMIS) traction table-assisted anterior approach and the traditional posterolateral approach (PLA) on THA for femoral head necrosis.

Methods: A total of 150 patients with femoral head necrosis, admitted between September 2019 and May 2022, were included in this study.
