Irreducible isolated subtalar dislocation: a case report.
Subtalar dislocations are uncommon and account for approximately 1% of all dislocations. Optimal management is by immediate closed reduction under general anesthesia. We report 3 cases of irreducible, isolated subtalar dislocation that required an open procedure. Closed reduction failed in 2 patients with lateral dislocation due to interposition of the posterior tibialis tendon caused by a large tear of the flexor retinaculum. The flexor retinaculum was accurately reconstructed after the reduction. In the third case, a medial dislocation, a displaced extensor retinaculum prevented relocation of the talar head and required resection. We also discuss the mechanisms for irreducible subtalar dislocations.
