Ankle sprains are common. Midfoot ligaments, particularly the dorsal ligaments of the Chopart joint complex, can be injured in combination with other ankle and foot injuries via an ankle sprain, but are clinically difficult to detect. The prevalence of injury to dorsal midfoot ligaments may be underreported as they can be overlooked, underappreciated, and underdiagnosed. Symptoms can include chronic pain, long-term functional limitations, and physical disability due to lack of timely management. Sonographic assessment of the ankle and foot following an ankle sprain should include assessment of the dorsal midfoot ligaments. This paper will provide a description of the sonographic anatomy, appearances, and assessment of the dorsal ligaments of the Chopart joint complex. Early diagnosis of injury can allow for appropriate management and treatment.
