[Reconstruction of the acetabular roof in cemented total hip replacement]

Acetabular roof reconstruction technique for primary cemented THR according to Zuk is presented in a series of 48 patients. No screws or bone bolts were used for cancellous graf fixation. In 30 patients the graft was sufficiently remodeled within 10-12 months, in 16 cases it lasted 1.5-2 years. Longer remodeling time depended on the size of acetabular defect, coexisting conditions and postoperative complications. In 2 cases an autolysis of the graft occurred; one patient underwent prolonged corticosteroid therapy before, the other one was exposed extensively to chemical substances prior to surgery. Aseptic loosening of the acetabular component followed.
