Femoral Head Fractures: Evaluation, Management, and Outcomes.

Abstract

Fractures of the femoral head typically occur after high-energy trauma. Radiographs and cross-sectional imaging are used to appropriately classify and identify associated injuries or morphologic characteristics that may influence management. Identification of the radiographic and clinical hallmarks of an irreducible variant is critical to optimizing the patient's outcome. Nonsurgical treatment can be used in the setting of small, infrafoveal femoral head fractures without hip instability. When surgical treatment is indicated, an anterior (Smith-Petersen), posterior (Kocher-Langenbeck), or surgical hip dislocation approach may be used depending on injury details and surgeon preference. The purpose of this review was to summarize current evidence on femoral head fractures regarding indications, variant patterns, surgical approaches, and outcomes.
