Dislocation of the talonavicular joint: case report.

Dislocation of the talonavicular joint is rare, caused by severe abduction or adduction of the forefoot. Proper reduction is necessary to avoid equinovarus deformity, ankylosis, or degenerative arthritis. A case of talonavicular dislocation with fracture of the head of the talus in a 52-year old woman is reported, with delayed treatment by open reduction using Kirschner wires and casting for 7 weeks. This patient is successfully employed as a waitress 2 years postinjury.
