Abstract
Objective To analyse the long-term results of the cementless, metaphyseal anchorage type, CLS Spotorno stem (Sulzer/Zimmer). Material y methods A review has been made of 166 patients in whom were implanted, primarily and consecutively, 189 CLS (CementLess Spotorno) (Sulzer/Zimmer) stems. The mean follow up was 13 years. The clinical parameters were assessed using a modified Harris scale, and the radiological ones according to the Gruen zones. The stem sinking measurements were also analysed. Results The mean follow up was 180 (156–228) months. Twelve patients (12 stems) died and 24 patients (29 stems) did not complete the follow up for different reasons. Thus the study was carried out on 130 patients (148 stems) who had the minimum follow up. The overall survival rate of the stem was 95% (confidence interval 89–98%) at the end of follow up. The Harris scale scores increased from 48 (9–76) points before surgery to 90 (63–100) points at the end of follow up. Conclusions CLS femoral stem obtains excellent long-term clinical and survival results.
