Postoperative Clubfoot Orthosis

Twenty-one patients with 27 surgically corrected idiopathic clubfeet were reviewed retrospectively to determine the effectiveness of the postoperative clubfoot orthosis in maintaining correction. The orthosis is a static, adjustable knee-ankle-foot orthosis design. Final follow-up foot measurements were compared with postoperative values to measure loss of correction. Patients treated with the orthosis were compared to an agematched group treated with Denis-Browne bars.
Correction of equinus, varus, and cavus was maintained, but correction of internal rotation and adductus was lost. No significant difference existed in loss of correction between the two devices. The study suggests that the custom made knee-ankle-foot orthosis is as effective as the Denis-Browne bar, but neither may control rotation and adductus completely. The cost is reasonable. Complaints and adjustments were few, but further data are needed to define the applications and limits of orthotic management in corrected clubfeet.
