title: Bilateral congenital subtalar dislocation: a case report.
abstract: Fixed bilateral congenital subtalar dislocations were identified in a 2.5-year-old boy. The patient had been treated previously with a short-leg cast on each foot for 2 months. On presentation the patient ambulated on the medial malleoli and medial aspects of his feet. The patient's activity was limited by pain. At 2.5 years of age, open reduction and pinning of bilateral subtalar joints with soft tissue release and lengthening of the achilles, peroneal, and extensor tendons was done. A thick fibrous band connected the talus and calcaneus laterally. Postoperative treatment included casting for 12 weeks and wearing rigid ankle-foot orthoses which he used for 8 years. There was no recurrence at 10-year followup. The patient has been brace-free for 2 years and is able to ambulate and play school sports without pain. The patient's subtalar range of motion is normal. Radiographic alignment is near normal without degenerative changes. To the authors' knowledge, there has been no previous report of this condition in the literature.
