The management of the foot and ankle in arthrogryposis multiplex congenita.

Sixty-six deformities of the foot and ankle in forty-two patients with arthrogryposis multiplex congenita were reviewd. Pes equinovarus proved particularly difficult to treat as there was a tendency for the deformity to recur because of the thick and rigid capsule. Intracapsular procedures were more successful than those done adjacent to the joint. Wide capsulotomy or talectomy were the best procedures under the age of three years and triple arthordesis was most successful for the older child.
