[Results of femoral varus osteotomy in the treatment of Legg-Calvé-Perthes disease].

The authors studied a group of 52 patients with Legg-Calvé-Perthes disease who had been treated by femoral varus osteotomy (54 osteotomies) aiming to show the end results and complications of the procedure based on Stulberg et al's evaluation. Regarding this classification of results were found 19 osteotomies (35.1%) with a good result (Stulberg's Groups 1 and 2), 35 (64.8%) with a fair end result (Stulberg's Groups 3 and 4) and none poor result. Few complications were observed in this series: pseudarthrosis occurred in three cases; Trendelemburg was observed in five patients postoperatively and overgrowth of the greater trochanter was observed in seven patients. In nine patients it was observed a significant leg length discrepancy with more than 2.1 cm of difference. However by the end results observed we may say that good results can be obtained with this technique in the treatment of patients with Legg-Calvé-Perthes disease. It is very important the indication criteria adopted based on the prognosis of the individual case studied.
