title: Complications of varus derotation osteotomy in the treatment of CHD during growth.
abstract: Complications of varus derotation osteotomies in the treatment of congenital hip displacement (CHD) are reported. Only "true" complications were considered, that is, those related to errors in technique, while those related to errors in indications were excluded. An analysis of 150 cases with a mean follow-up of 4.2 years revealed that "true" complications are a rare occurrence. Among these the most frequent are dysmetria (20%), and infection (2.6%). There was only one case of osteochondrosis (0.6%). The dysmetria (usually under 2 cm) rarely required further surgical treatment involving temporary epiphysiodesis of the homolateral knee, while the infection responded satisfactorily to combined conservative and surgical treatment.
