A 67-year-old male with a history of bilateral total hip arthroplasties (THA) several years ago presents with left hip pain after a fall. He was walking downstairs and slipped, twisting his leg internally and with adduction and flexion of the hip to catch himself. He denies falling but felt an immediate pop in his left hip and could no longer bear weight. AP and lateral radiographs of the pelvis and left hip were obtained and are shown above (Image 1.
