Intrapelvic component retrieval via anterior inferior iliac spine osteotomy in revision total hip arthroplasty.

Abstract

In the revision setting, intrapelvic acetabular components provide a unique set of challenges for the treating surgeon. Retrieval is complicated by complex anatomical relationships within the pelvis and historically, surgeons have used multiple approaches to safely retrieve the cup. We present the case of a 53-year-old female with intrapelvic migration of the acetabular components of her total hip arthroplasty. Patient was treated through a novel, single incision approach with utilisation of an anterior inferior iliac spine (AIIS) osteotomy. An AIIS osteotomy allows for improved visualisation within the pelvis and safe retrieval through a single exposure without compromising the ability to perform definitive, revision reconstruction. At 1-year follow-up, the patient has had no complications related to infection or failure of the implants. Ambulation is performed with the aid of a cane in the community with mild, occasional pain.
