Total Hip Arthroplasty Using Kerboull-Type Acetabular Reinforcement Device for Rapidly Destructive Coxarthrosis

We studied 20 primary cemented total hip arthroplasties performed using Kerboull-type acetabular reinforcement device for rapidly destructive coxarthrosis. The average patient age at the time of surgery was 68.3 (range, 60-77) years. The mean follow-up period was 6.3 years (3.8-11.8). The mean preoperative Japanese Orthopedic Association hip score was 38.1 (16-70) vs 85.2 (70-93) at the latest follow-up. The radiographic outcome in 20 hips showed no migration or aseptic loosening. A partial radiolucent line at the cement-bone interface was noted in 2 hips (10%), but no progression occurred. There were no major complications. No patient required repeated surgery. The use of Kerboull-type acetabular reinforcement device for rapidly destructive coxarthrosis provided satisfactory 3-year to 11-year clinical and radiographic results.
