Atraumatic Fracture of Newer Generation Ceramic Head Three Days Post-op: A Case Report

A 73-year-old female experienced an atraumatic fracture of a BIOLOX delta ceramic femoral head following uncomplicated right total hip arthroplasty using a ceramic-on-polyethylene bearing. The fracture occurred post-operatively, as revealed by radiography after the patient reported a clunking sensation and leg shortening. Revision surgery involved replacing the fractured head and liner with careful removal of ceramic debris. The patient recovered well with no further complications. This case highlights the rare occurrence of an atraumatic fracture in a newer-generation BIOLOX delta ceramic head. This suggests possible manufacturing defects or taper mismatches and emphasizes the importance of thorough implant evaluation.
