Abstract

In 1997 the “step-less” SL Plus (Endoprothetik, Rotkreuz, Switzerland) cementless total hip arthroplasty was introduced to our unit. During the passed 12 months, a retrospective study has been performed in order to evaluate the clinical and radiographic results of this arthroplasty. The preliminary results of the first 50 patients to have completed the clinical and radiographic follow-up have been evaluated. Of the 50 patients, 56 primary total hip arthroplasties were performed, in all cases the SL Plus stem was used. In 52 cases the cementless Doetz acetabular cup, made by the same manufacturer, was used. The other 4 acetabular components were: 2 long stemmed cementless components for developmental dysplasia, 1 standard cementless cup and 1 cemented cup, made by other manufacturers. All patients were reviewed clinically and radiographically. The mean follow-up time was 3 years, range 2 – 5 years. The mean Harris Hip Score was 90 (37 – 100). Patient satisfaction was: 98% satisfied, 2% dissatisfied (p < 0.001). Radiographic assessment demonstrated that all 52 (100%) Doetz acetabular cups osseointegrated, with 53 (95%) acetabular cups osseointegrating in total (p < 0.002). Of the SL Plus stems, 44 (79%) osseointegrated (p < 0.002). The following post-operative complications were observed: 2 dislocations, 2 superficial wound infections, 1 myocardial infarction, 1 sciatic nerve palsy and 1 deep vein thrombosis. The overall complication rate is high at 13%, but with no implant related failures. Nevertheless, the preliminary clinical and radiographic results of the SL Plus stem and Doetz acetabu-lar cup total hip arthroplasty are encouraging.
