Massive deficiency of acetabular bone stock is a challenging problem in the increasing number of patients who need a revision of the failed hip arthroplasty. Oblong acetabular cup has been presented as an alternative reconstruction technique for hips with extensive acetabular bone loss. The aim of this study was to present our results with the use of a bilobed acetabular component inserted during revisional surgery, to define indications, and to introduce this method into our orthopaedic practice. Seven patients underwent revisional hip arthroplasty with a cementless oblong acetabular component between September 2000 and June 2002. Six patients underwent revisional hip arthroplasty, and in one primary hip arthroplasty by oblong acetabular component was performed because of bone defect of acetabulum after gunshot fracture. The average follow up was thirteen months. Radiographic analysis in all patients demonstrated stable bone incorporated acetabular component with the restored hip. All the patients walked with full weight bearing and were without pain. On the basis of our experience we find this method statisfactory in certain types of bone defefects of acetabulum, and that it provides stable reconstruction of acetabulum with the correction of hip joint.
