title: Locked inferior fracture dislocation after total hip arthroplasty.
abstract: Acetabular fracture in conjunction with dislocation after total hip arthroplasty is a rarely reported event. We describe such a case with a unique fracture dislocation pattern, whereby the prosthetic femoral component dislocated inferiorly, fracturing the pelvis, and was locked in this position. The patient was treated with closed reduction under anesthesia and the fracture healed without further surgical intervention. However, she has experienced subsequent instability episodes and we have recommended revision surgery.
