Distal calcaneal osteotomy in resistant talipes equinovarus.

In resistant talipes equinovarus deformity, posterior medial release alone may be inadequate. Procedures involving the lateral column are sometimes necessary. Thirty-nine patients were treated by a distal calcaneal osteotomy and plantar fasciotomy. Good results were obtained in 30 of 39 patients; two had fair results and seven of 39 had poor results. Of the lateral column procedures, distal calcaneal osteotomy avoids the articular surfaces and provides for easier rotational positioning and correction of the forefoot. Older patients who have had multiple operations and, potentially, more severe pathology do not do well with this procedure. Preoperative evaluation of certain radiographic parameters is important in patient selection for these procedures.
