Acetabular Component Removal Systems

Abstract

• » As primary total hip arthroplasty procedures continue to rise, acetabular revision surgery will be in increasing demand.
• » Treatment of acetabular component failure and associated bone defects depends on patient characteristics, the degree and location of bone loss, the ability of the columns to support biologic fixation, and the presence of pelvic discontinuity.
• » In revision total hip arthroplasty, technological advances have been made to address limitations of acetabular cup removal while preserving host bone stock.
• » The goal of acetabular revision reconstruction should be to obtain stable fixation and restore the hip center. The various acetabular cup removal systems are discussed.
