Injuries to the Chopart joint complex: a current review.

Abstract

Chopart complex injuries (CCIs) are thought to be uncommon; however, recent literature states the rate of misdiagnosis to be between 20 and 41%. Chopart complex injuries are not ankle injuries, with which they are initially confused due to a similar mechanism of trauma in many cases. Injury to the Chopart complex commonly affects multiple structures. The key to optimal treatment is a high index of clinical suspicion combined with timely accurate imaging studies. Careful diagnostic workup with high-quality radiographs of the foot in neutral position should be obtained. Computed tomography (CT) and/or magnetic resonance imaging (MRI) are recommended to accurately assess bone and soft tissue injury. CCI frequently leads to prolonged swelling, pain and disability. In some cases, it may result in a posttraumatic flatfoot deformity.
