Role of talocalcaneal osteotomy in clubfoot surgery: results in 31 surgically treated feet.

The most important deformities in clubfeet can be demonstrated by simultaneous arthrography of the talonavicular and talocrural joints. In patients with a severe talar deformity, wedge osteotomy through the talar neck and calcaneus has been performed as a prerequisite for correction. Our series consisted of 20 patients with 31 idiopathic clubfeet with pronounced talar deformity. The mean observation time after osteotomy was 11 years 3 months. The principles and aims are described, as are the indications for talocalcaneal osteotomy. Results were good in 19 feet (60%), fair in six (20%), and poor in six (20%).
