Acetabular revision using acetabular roof reinforcement ring with a hook

This study evaluated the clinical and radiographic results of 37 acetabular revisions using an acetabular roof reinforcement ring with a hook (ARRRH). The average age of the patients was 52.4 years, and the mean follow-up period was 4.5 years. The mean Harris hip score had improved from 49 points pr...

Description
Summary:This study evaluated the clinical and radiographic results of 37 acetabular revisions using an acetabular roof reinforcement ring with a hook (ARRRH). The average age of the patients was 52.4 years, and the mean follow-up period was 4.5 years. The mean Harris hip score had improved from 49 points preoperatively to 87 points at the final follow-up. The bone graft was radiographically incorporated in all cases. The postoperative complications were a hip dislocation in 3 cases, nonunion of the greater trochanter in 1, infection in 1, discomfort at the autograft donor site in 3, and 2 cases of hook failure. An ARRRH combined with a morsellized bone graft is a useful treatment particularly in moderate-to-severe acetabular bone deficiencies.
