The modified Chopart's amputation.
A modified Chopart's amputation has been designed to overcome the complications of the traditional Chopart's amputation of plantar flexion and skin breakdown over the anterior talus and calcaneus. The modifications are: (1) contouring of the talus and calcaneus; (2) transfer of the anterior and posterior tibialis tendons and the extensor communis and hallucis to the neck of the talus and sustentaculum tali; (3) anterior advancement of the plantar flap; and (4) lengthening of the tendo Achillis. This procedure has been performed in a prospective manner on eight feet in six children. An average 3.5-year follow-up term has not revealed any complications. The modified Chopart's procedure appears to be a functional, useful amputation for children requiring foot ablation secondary to congenital malformations.
