Critical analysis of results in club feet treated surgically along the Norris Carroll approach: seven years of experience.

We have used the Norris Carroll approach to the surgical release of resistant club feet for the last 7 years. Critical analysis of 33 idiopathic club feet, after an average follow-up of 4 years, by clinical and radiological methods showed 82% satisfactory results and 18% unsatisfactory. The results indicated a trend toward limited plantar flexion in these feet, as well as mild supination that disappeared with walking. The advantage of the dual skin incision approach is easy access to both plantar medial and posterolateral structures. The calcaneocuboid joint is released and emphasis is put on release of the lateral tether.
