Legg-Calvé-Perthes follow-up study.

We present here a follow-up study concerning Legg-Calvé-Perthes. This study about 71 hips shows that the Catterall grouping, age and "at risk signs" are still to be considered as very important prognostical factors. A definitive and indispensable scheme of treatment has not yet been advanced, especially because the right etiology still remains an obscure point.

Triple arthrodesis and Lambrinudi arthrodesis. Literature review and follow-up study.

A literature review is presented about triple arthrodesis and Lambrinudi arthrodesis including indications, techniques, complications, and a more extensive review of some specific indications. Forty-eight patients were operated on between 1961 and 1977, 25 of whom were reviewed at follow-up. Our follow-up study shows a rather high rate of pseudarthrosis, with however a normal failure rate.
