Patients will present with immediate pain and swelling on the top (dorsal) and outside (lateral) of the foot. Therefore athletes, such as football players and gymnasts, are at risk of a Chopart’s joint sprain. Injuries to the transverse tarsal joint (Chopart joint) occur when the foot and ankle is flexed, twisted (inverted/everted) and loaded at the same time. Figure 1: Transverse Tarsal Joint (Chopart Joint) Although a transverse tarsal joint injury/sprain and an ankle sprain occur via a somewhat similar mechanism with a roughly similar area of injury the length of recovery is usually much longer in patients who have suffered a transverse tarsal joint injury. Transverse joint sprains typically do not require surgery, although some injuries to Chopart’s joint have associated fractures or dislocation and may require surgery. After the pain and swelling has settled (often a number of weeks) formal physical therapy can be started. Treatment involves rest, anti-inflammatory medications (if tolerated), and immobilization in a cast or walker boot. Diagnosing a transverse tarsal joint injury is made through a combination of patient history, physical examination, and x-ray imaging. Patients will have significant pain and will often be unable to weight-bear. The most common mechanism of this injury is an inward twisting and loading of the foot -somewhat similar to the mechanism that causes an ankle sprain. A sprain is the most common injury to the transverse tarsal joint and occurs when some or all of the ligaments holding the joint together are torn.
It is the joint that connects the hindfoot to the midfoot.
The transverse tarsal joint, also called the midtarsal or Chopart’s joint, is made up of the joints between the calcaneus and cuboid, and the talus and navicular (Figure 1).
