Injuries involving the Chopart joint complex are relatively rare and frequently missed or misdiagnosed, often leading to a poor functional outcome. This study was performed to determine the outcome and morbidity in patients with Chopart joint injuries, and to increase awareness of this severe injury. Patients with a Chopart dislocation or fracture-dislocation, treated between January 2004 and January 2010, were identified using the appropriate diagnosis code and reviewing all radiographs of patients diagnosed with hindfoot or midfoot injuries treated at our institution. Data on patient characteristics, trauma mechanism, delay, and treatment were collected using patient files, operation reports, and by reviewing radiographs. Outcome was determined using the American Orthopaedic Foot & Ankle Society midfoot score and a visual analog scale satisfaction score, in patients with a minimum follow-up of 6 months. Nine patients (1.5 per year) were identified, including 6 women. The mean patient age was 41.6 ± 25.1 years. The trauma mechanism was sprain or sports injury in 5 (55.6%), motor vehicle accident in 3 (33.33%), and a fall from height in 1 (11.11%) case. Seven patients with an average follow-up of 31.3 ± 19.2 months reported a mean American Orthopaedic Foot & Ankle Society midfoot score of 72 (range, 32-100) points and a mean visual analog scale score of 7.1 (range, 5-10). Four (57.14%) patients still experienced pain or had limitations in daily activities at the time of the final follow-up. This study supports the conclusion of previous studies, which stated that a higher level of awareness is needed to prevent permanent disability.
