Abstract
Acetabular bone loss is a problem in primary and revision Total Hip Joint Replacement (THJR). Impaction bone grafting is one method of dealing with this problem. We looked at the results of two surgeons who use this method at North Shore Hospital, Auckland.
A retrospective study was carried out on all patients who had acetabular impaction bone grafting carried out as part of THJR, whether primary or revision. All operations were performed by two surgeons, Mr Rob Sharp and Mr Bill Farrington. Patients were assessed in clinic at varying time intervals post grafting, and were functionally scored.
33 patients underwent impaction grafting, a total of 35 acetabular grafts. Of these the male to female ratio was 16:17, and the mean age range was 46–82 years. Average Harris hip score was 79 (Min 54 Max 95), and the average Oxford score was 39 (min 13 Max 48). There was one failure, 3 dislocations, and1 sciatic nerve palsy.
Impaction bone grafting is one method, which can be utilised to reconstruct acetabular bone loss, with the additional advantage of restoring bone stock. We found high rates of patient satisfaction, and a low failure rate.
