Implant fracture is a rare but devastating complication of total hip arthroplasty (THA). We present the case of a patient with a history of prior acetabular fracture who underwent conversion to a dual mobility (DM) THA and subsequently fractured at the neck of the femoral component 7 years after surgery. At revision, both the femoral and acetabular components were noted to be clinically retroverted, suggesting chronic anterior impingement as the cause of the catastrophic failure.
