Subtalar joint dislocations, although not common, have been increasing in frequency over the last decade. Generally, subtalar joint dislocation can be treated successfully with closed reduction and a short period of cast immobilization. The majority of patients will suffer minimal disability, with subtalar joint stiffness as the primary complaint. This report includes four cases of suspected joint dislocation or subluxation with occult intra-articular fractures identified only by CT scan following essentially normal radiographs. Evidence seems to indicate that CT scanning in patients with suspected subtalar joint subluxation or dislocation and normal radiographs is justified.
