Subtalar joint dislocation (STJD) is an uncommon injury, but carries with it a potential for significant functional disability. We hypothesized that a significant number of injuries associated with subtalar joint dislocation may be unrecognized by plain radiographic examination. Therefore, we reviewed the records of all STJDs over a three-year period, identifying nine cases. The majority of injuries occurred in men (78%) with a mean age of 29 years. Overall, the mean age at injury was 32 years. The right lower extremity was most frequently injured (87.5%). Plain films initially diagnosed a STJ dislocation in all patients. A CT scan was performed in all cases. In 100% of patients, CT identified additional injuries missed on initial plain radiographs. In 44% of patient, new information gathered by CT dictated a change in treatment. Based on our findings, we conclude that CT is an invaluable tool to assess for associated injuries in STJ dislocation, and should be performed in all cases of STJ dislocation.
距下关节脱位（STJD）是一种罕见的损伤，但有导致严重功能残疾的可能性。我们推测，大量与距下关节脱位相关的损伤可能无法通过普通X线检查发现。因此，我们回顾了三年期间所有距下关节脱位的记录，确定了9例病例。大多数损伤发生在男性（78%），平均年龄为29岁。总体而言，受伤时的平均年龄为32岁。右下肢最常受伤（87.5%）。所有患者最初均通过平片诊断为距下关节脱位。所有病例均进行了CT扫描。100%的患者CT发现了最初平片漏诊的其他损伤。44%的患者，CT获取的新信息决定了治疗方案的改变。基于我们的发现，我们得出结论，CT是评估距下关节脱位相关损伤的宝贵工具，所有距下关节脱位病例均应进行CT检查。
