We Reviewed 145 consecutive patients who had total hip replacements us
ing uncemented CLS Spotorno femoral stems which achieve primary fixati
on with bony ingrowth which occurs later mainly in the metaphyseal reg
ion. The mean age was 54.9 years and average follow up 7.8 years. The
Merle d'Aubigne and Harris hip scores were used for evaluation, togeth
er with plain radiographs. Current medium term follow up showed a surv
ival rate of 96.7% and a good functional score in more than 90%. Speci
al attention was paid to postoperative thigh pain which occurred in on
ly one patient. These results are encouraging, but a follow up of more
than 10 years is required before comparable results to cemented stems
can be claimed.
