Acetabular Revision

An Acetabular Revision is surgery where the old, defective acetabular component (cup) is removed, and a new acetabular shell and liner are inserted. Screws are used in many cases to secure the acetabular component to the pelvis. Improved liner materials have decresed the need for subsequent revision procedures.

Severe polyethylene wear and chronic hip instability (dislocation) are the major reasons for acetabular revisions. The acetabular component can fail due to trauma, degeneration of pelvic bone structure, or failure due to the excessive polyethylene wear. Chronic dislocation results from excessive polyethylene wear, trauma, or malposition of components. Acetabular revisions may also require revision of the femoral component. The need for revision and the extent of the procedure is determined after proper evaluation of your condition by the Orthopaedic Surgeon.

Revision Acetabular Components can be cementless or cemented, depending on the patients individual needs.
