A new technique for removing noncemented acetabular components in revision total hip arthroplasty

Abstract

Removal of noncemented acetabular components during revision surgery can be a time-consuming technical challenge, resulting in exacerbation of defects and compromised bone stock. These factors are deleterious to reconstructive efforts and can compromise clinical results. A technique is described that can accomplish timely removal of noncemented acetabular components. The advantages of this technique include no further weakening of the remaining structural supports, minimal bone loss, avoidance of intrapelvic perforations, and reduction in operative time.
