[Subcapital osteotomy of the femoral neck in the treatment of coxa vara in adolescence--long-term results].

The authors present a group of 16 adolescents suffering from coxa vara treated in the years 1967-1987 for a severe slipped capital femoral epiphysis by subcapital osteotomy. The authors deal with the etiology, symptomatology and treatment with special regard to the severe slip. Spica cast was applied in most operations and no internal fixation was used. In the so far latest female patient the femoral head was fixed after osteotomy by Kirschner wires according to Dyas Aries. In the discussion the authors report considerably lower percentage of complications in the longterm examination, mainly as concenns the avascular necrosis of the femoral head in comparison with most works presented both in the Czechoslovak and foreign literature. These results are explained by a proper indication, prepping technique, adequate operative technique and a consistent adherence to longterm nonweight of the extremity operated on. Preventive epiphyseodesis on the intact hip joint has not been performed.
