Coxa vara: surgical outcomes of valgus osteotomies

J Pediatr Orthop. 1997 Mar-Apr;17(2):220-4. doi: 10.1097/00004694-199703000-00016.


Since the 1950s, valgus-producing femoral osteotomy has been the preferred treatment for significant coxa vara. Despite well-performed surgeries, the literature cites recurrence rates of 30-70%. The present study reviews our past 15 years of surgical experience for coxa vara; 26 children with 37 affected hips were retrospectively evaluated for outcome following valgus osteotomy. Both congenital and acquired types of coxa vara were included. Overall recurrence rate following valgus osteotomy was 50%. Age at time of surgery, type of surgery, and type of implant and etiology were found to have no bearing on recurrence. However, if Hilgenreiner's epiphyseal angle was corrected to < 38 degrees, 95% of children had no recurrence of varus. In contrast, head-shaft angle was found not to be a reliable indicator of appropriate correction. Only six of 37 hips required pelvic osteotomy (five Pemberton, one Chiari) for dysplasia, and four of these had developmental dysplasia of the hip as the underlying etiology for their coxa vara. However, if the proximal femur was corrected and maintained before age 10, 83% of children had excellent acetabular depth, spherical congruency, relief from pain, and correction of Trendelenburg gait at latest follow-up.
