CLS femoral component.

Between 1984 and 1988, we performed 540 total hip replacements, using the CLS device as an uncemented femoral component. The reasons that led to this type of prosthesis and our surgical technique are illustrated. In the whole series of treated patients, we found a smaller number of complications and in 128 cases with a minimum 2-year follow up, we had very good results. The evaluation of radiologic findings show that the subsidence of the device occurred in three cases only.
