Surgical aspects of limb deformity in hypophosphatemic rickets.

Our assessment of the surgical correction of bowleg deformity in eight patients with sex-linked dominant hypophosphatemic rickets showed the best results in patients having staged, proximal tibial osteotomies at completion of growth. Lack of medical therapy was associated with recurrent genu varum or markedly delayed union. Undercorrection may be prevented by using the hip-knee-ankle axis to plan the realignment procedure.
