Subtalar Joint Dislocations

Abstract

Dislocations of the subtalar joint are rare injuries. The anatomy, pathophysiology, treatment, and prognosis of subtalar joint dislocations have been well described in the literature. The purpose of this paper is to review the current literature on subtalar joint dislocations, as well as outline those aspects of the anatomy, pathomechanics, and treatment pertinent to care of the patient with subtalar joint dislocation. In addition, complications and obstacles to reduction are described. Subtalar joint dislocations, although not common, have increased in frequency over the last decade. Generally, they can be treated successfully with closed reduction and a short period of cast immobilization. The majority of patients will suffer some disability with subtalar joint stiffness the primary complaint. Associated intra-articular fractures increase the risk of posttraumatic arthrosis.
