First Experience in Cemented Polished Stem of Exeter THR.

: The authors evaluate first results of implantations of Exeter cemented polished femoral component and present their experience in its use. In 1996 and 1997, 140 of these stems were implanted at their Clinics in 77 females and 63 males, average age 64 years. In 69 cases the right side was affected and in 71 cases the left one. The most frequent indication was idiopathic primary osteoarthritis of the hip (99 cases). Clinical results were evaluated on the basis of Merle d Aubigne and Postel score. In 96 cases the results achieved were excellent, in 5 cases they were average and only in one case the result was poor. In 5 patients the radiograph showed 5 degrees varus postition of the stem. Symptoms of aseptic loosening were not found in the follow-up period. In four cases after the surgery the cement penetrated through diaphyseal cortex. In view of authors it may be caused by the effort of the surgeon to press maximally the cement in bone trabeculae and also by osteopenia in older patients. Key words: THR, Exeter cemented femoral component, osteoarthritis of the hip.
