Surgical Technique Utilizing Porous Metal Augments for Acetabular Deficiencies


Dr. Berend and his team perform a revision total hip replacement in a 72-year-old woman who had undergone primary total hip arthroplasty for osteoarthritis. She had experienced multiple dislocations and was treated with combinations of closed reductions and revision of the acetabulum. She later developed a loose cup with superior migration that was causing her pain. This particular patient's condition was further complicated by the presence of Staphylococcus aureus in her hip. The goals of the surgery were to restore the anatomic hip center, achieve cup stability, and decrease the risk of postsurgical dislocation by the utilization of a large femoral head. Dr. Berend describes his surgical approach and demonstrates acetabular preparation, trialing of the cup and acetabular augment, positioning of the augment, bone grafting, "unitization" of the augment and cup; final cup insertion and fixation; and trialing of the reconstruction.
