[Valgus osteotomy in the treatment of sequelae of ischemic post-dysplastic necrosis of femoral head in children. Part I: surgical technique.].

: The authors deal with the surgical technique of the reconstruction of coxa vara in children. They present valgus osteotomy on the Pauwels principle with the simultaneous apophyseodesis of the growth plate of greater trochanter, lengthening of fermoral neck fixed by 120 degrees angled blade plate for adolescents allowing a parallel lengthening of the lower limb. The main indication for this technique is postdysplastic coxa vara and congenital coxa vara in children. However, it may be used also in adults. The benefits of the method consist in the possibility of exact planning of the surgery. Key words: valgus osteotomy, reconstruction, DDH, ischemic necrosis of the femoral head.
