Abstract

There are no clear guidelines on the treatment of relapsed clubfoot, which is a relatively frequent and difficult problem in paediatric orthopaedics. Numerous operative interventions are mentioned in the literature as suitable for correction of a residual deformity of the food. There are numerous soft tissue procedures (release operations, tendon extensions, tendon transfers and redressement by means of a fixateur externe) and osseous interventions (osteotomies, arthrodeses) that can be carried out in isolation or in combination. In the present article two types of osteotomy are described that make it possible to correct the most frequent forms of relapsed clubfoot: combined closing wedge cuboid and opening wedge cuneiform osteotomy for correction of adductus and supination of the forefoot and the calcaneal osteotomy after Dwyer for correction of varus position of the calcaneal part of the foot. The combined osteotomy in the midfoot involves shortening of the lateral ray with simultaneous lengthening of the medial ray, with the wedge out of the cuboid bone inserted into the medial cuneiform bone, which leads mainly to correction of the adductus, but does also make it possible to achieve partial correction of the supination with an osteotomy right through the cuneiform bone. In the case of rigid foot deformities it is advisable to carry out preliminary stretching by means of a fixateur externe, while in the case of a bean-shaped foot a combination of osteotomy and medial and lateral release is recommended. Results of a follow-up study of our own patients treated with this operation have shown that no revision operations were necessary in any of the patients with idiopathic clubfoot. Other types of osteotomy described in the literature as suitable for correction of residual forefoot adductus and supination are also mentioned in this paper. Thecalcaneal osteotomy after Dwyer, for which a lateral approach is always used, generally leads to satisfactory correction of varus position of the calcaneal part of the foot. It the calcaneus is found to have a short posterior part this osteotomy is modified so that instead of taking the form of a wedge osteotomy with lateral closing it is followed by a lateral displacement. In this way it is possible to prevent making the already short posterior calcaneus even shorter. Both the combined midfoot osteotomy and the calcaneal osteotomy after Dwyer can be performed alone or in combination with each other or with different operative interventions.
