Total hip arthroplasty revision is increasingly becoming a common procedure, but the acetabular bone loss and the advanced age of the patients make revision procedures extremely complex and technically demanding. The aim of the present work is to examine the clinical and radiological results of the Burch-Schneider anti-protrusio cage (APC) implanted in revision hip arthroplasty with severe acetabular bone deficiency in elderly people. Between February 1994 and November 2005, a total of 60 revision operations of acetabular components were performed in 60 select patients (42 females and 18 males), using the Burch-Schneider APC. The indication for the Burch-Schneider APC use was massive pelvic bone loss with migration of the prosthesis cup and high-grade acetabular defects (type III or IV AAOS). The mean age at the time of surgery was 82 years (range 78-85 years). Polymethylmetacrylate cement (PMMA) was used to fill bony deficiencies in all the procedures. No graft was used. The average Harris Hip Score had improved from 28.2 preoperatively to 82.5 points at the time of follow-up. According to the classification of Gill et al., we have seen no Burch-Schneider cages definitely loose or probably. Only one acetabular component has been revised (for recurrent dislocation). Acetabular reconstruction with the use of cement and an acetabular support ring appears to have a useful role in the treatment of severe acetabular bony deficiency in elderly patients and may provide a definitive reconstruction. |
