Medial talo-calcaneal coalition. Case report.
Medial talo-calcaneal coalition is an uncommon developmental anomaly consisting of a bony projection arising from the postero-medial aspect of the sustentaculum tali, which may articulate with another bony projection from the medial aspect of the talus. Fibrous, cartilaginous or bony ankylosis may occur. It usually presents in adolescents, and causes pain following exercise. It may cause a lump, and can predispose to flat foot and early osteoarthrosis. This condition is easily overlooked on routine views of the ankle, and may require oblique views and tomography for its detection and clarification.
