Four cases of subtalar dislocation were treated. All cases were men whose average age was 23 years (range from 16 to 32). These injuries occurred either from sports activities or traffic accidents. There were three lateral and one medial dislocations. One case involved in a traffic accident suffered calcaneal open fracture, and another case talar body fracture. Closed reductions under intravenous anesthesia was performed for closed dislocation in the emergency department and these were successful. Open reduction, debridement, and osteosynthesis under general anesthesia were performed on one case of calcaneal open fracture. Short leg cast or splint was applied for all cases after reduction.
The mean period of immobilization was 40.5 days (range from 21 to 60). The mean period of partial weight bearing was 43 days (range from 29 to 60) after reduction.
All patients complained of pain during sports activity or work, however arthritic change of the subtalar joint and avascular necrosis of the talus were not recognized.
