Femoral neck trunnion dissociations are rare complications of total hip replacements. This hardware failure is often due to underlying trunnionosis which is important to recognize. We present a case of a patient with dissociation at the femoral head-neck junction of a total hip arthroplasty (THA) with a Stryker Accolade TMZF femoral stem. There was no significant preceding trauma. The complication was visualized on radiography and confirmed during revision arthroplasty.
