title: Acetabular reconstruction using a Kerboull-type acetabular reinforcement device and hydroxyapatite granules: a 3- to 8-year follow-up study.
abstract: Between 1993 and 1997, 21 consecutive revision total hip arthroplasties were performed in 20 patients using hydroxyapatite (HA) granules supported by a Kerboull-type reinforcement acetabular device. Acetabular bone loss according to the American Academy of Orthopaedic Surgeons (AAOS) system was type II for 5 hips and type III for 16 hips. Autografts were used to reconstruct the major segmental defects in 6 hips. The mean follow-up period of the series was 5 years and 4 months. No migration of the socket was seen. Slight inclination of the acetabular device was noted in 1 hip without functional deficits. The mean preoperative Merle d'Aubigné hip functional score was 9.3 versus 15.4 at the latest follow-up evaluation. Acetabular reconstruction with HA granules and a Kerboull-type acetabular device provided satisfactory 3- to 8-year clinical and radiographic results.
