Surgical Approach Influences the Risk of Intraoperative Periprosthetic Femoral Fracture in Primary Total Hip Arthroplasty: A Retrospective Cohort Study

Surgical approach was associated with differences in the occurrence of intraoperative periprosthetic femoral fracture in primary THA. The anterolateral and direct lateral approaches demonstrated higher fracture rates compared with the posterolateral approach. However, given the retrospective observational design and the potential for residual confounding, these findings should be interpreted with caution and do not establish a causal relationship.
