title: [Dislocation of the cemented total hip endoprosthesis - risk and therapy.].
abstract: In 11 out of 1699 patients, who underwent a total hip replacement with a cemented THR during a 10 year period, dislocation of the prosthesis occured in the postoperative period. The operations were made using an anterolateral approach. Dislocation occured in 7 patients after a primary implantation (0,42 %) and in 4 patients after a revision operation (1,6 %). Reorientation of the acetabular component was necessary in 1 case, in 5 cases closed reduction was successful, in 3 cases open reduction was needed. Acetabular augmentation using a polyethylen acetabular shell and cortical screws was performed in 2 patients with recurrent dislocation of the prosthesis. In all cases it was possible to regain the stability of the prosthesis. The results were reviewed in average 46 months (20 to 82 months) postoperatively. In 1 patient deep infection arised after open reduction. Key words: total hip prosthesis, complications, dislocation.
