Midtarsal Joint Sprain

The Midtarsal Joint Sprain¬†is also known as Chopart’s joint injury and it consists of the talonavicular joint (between the talus and navicular bones) and calcaneocuboid joint (between the calcaneus or heel bone and the cuboid bone).

Injury to the midtarsal joint is rare but is more commonly seen in gymnasts, footballers and sports involving jumping.



Which Ligaments are Injured?

There are two ligaments which are most commonly injured and these may produce slightly different symptoms.

The Dorsal Calcaneocuboid ligament connects the Calcaneus and the Cuboid, on the top of the foot.

The Bifurcate ligament, is a Y shaped ligament, consisting of 2 parts – the Calcaneonavicular ligament (between the Calcaneus and Navicular) and the Calcaneocuboid ligament (which is a second ligament between the Calcaneus and Cuboid).
Symptoms of Calcaneocuboid Ligament Injury

  • Pain in the outside middle of the foot which may come on after an ankle sprain or similar injury.
  • Pain and swelling on the outside top of the joint.
  • Placing the foot into inversion may cause pain.
  • An MRI scan may be done to confirm the diagnosis.
  • An X-ray can be done to rule out a fracture.


Symptoms of Bifurcate Ligament Injury

  • Comes on after a severe ankle injury in conjunction with a fracture of the anterior process of the calcaneus.
  • Pain on the outside middle of the foot.
  • Pain is made worse by plantar flexion and supinating the foot at the same time (pointing the foot down and rolling it outwards).
  • An MRI scan can confirm the diagnosis and X-rays should be done to identify a fracture, particularly of the anterior process of the heel bone.

Treatment of a Midtarsal Joint Sprain

  • Treatment is similar to that of the calcaneocuboid injury with immobilisation for 4 weeks.

  • Surgery may be considered.
