METHODS OF RECONSTRUCTION OF ACETABULAR DEFECTS IN TOTAL HIP REPLACEMENT
Maged Ahmed Ismail Shaheen;
Abstract
Bone deficiency in the acetabulum can be encountered in primary and revision acetabular reconstruction. Primary deficiencies result from either an abnormality of growth or a condition that alters the shape of the acetabulum.
Bone deficiencies encountered during revision arthroplasty continue to be the most common. Many classification schemes have been formulated to describe acetabular deficiencies. The most commonly used schemes are those that are easy to remember, easy to reproduce, and are most useful in guiding treatment options.
The deficient acetabulum requires reconstruction so that the acetabular component has adequate bony coverage and support. This is to restore anatomy and leg length and restore bone stock for future revisions.
Management of acetabular deficiency in total hip arthroplasty can be extremely challenging. A successful outcome requires good orientation about applied surgical anatomy of the acetabulum, careful preoperative planning, identification of complex defects, and stable reconstruction. Acetabular deficiencies are classified according to clinical radiographs, anticipated bone loss during removal of implants, and intraoperative assessment of host bone stock.
