Is it hazardous or mandatory to release the talocalcaneal interosseous ligament in clubfoot surgery?: a preliminary report.

Extreme overcorrection and avascular necrosis are recognized complications in clubfoot surgery and are thought to be the result of division of the talocalcaneal interosseous ligament (TCIL). This is a preliminary report of a prospective study of the cases of 46 patients with 66 idiopathic clubfeet treated by means of soft tissue release using a posteromedial approach at a mean age of 9 months. The deformity was very severe in 51 feet and severe in 15.
