Treatment of residual adduction deformity in clubfoot: the double osteotomy.

Forefoot adduction is the most common residual deformity after clubfoot surgery. Surgical treatment of this deformity is often required for moderate and severe cases. This study reports the results of a closing wedge osteotomy of the cuboid and opening wedge osteotomy of the medial cuneiform in 39 feet. The average follow-up was 4.8 years. Clinical and radiographic improvement was seen in all patients, and no complications were seen. Surgery is advocated in children older than age 4, or when the medial cuneiform ossific nucleus is well developed.
