Midtarsal Joint Sprain

Tarsal bones - tarsal coalition

A midtarsal joint sprain is an injury to one or more of the ligaments holding the tarsal bones in the middle of the foot together. The exact location of pain will depend on the affected ligament. It is rare, but can occur in gymnastics, footballers, and jumping sports.

Symptoms of a midtarsal joint sprain

The symptoms and severity of a midtarsal joint sprain depends on which ligaments have been injured. However, in general:

  • You will normally feel pain on the outside middle of your foot.
  • Swelling may be visible on the outside top of the joint.
  • Certain foot movements will be painful.

What is a Midtarsal joint sprain?

Injury to the midtarsal joints is rare. However, it is more common in gymnasts, footballers, and those who do sports which involve jumping.

Foot ligaments

The midtarsal joint comprises:

  • The talonavicular joint, between the talus and navicular bones.
  • The calcaneocuboid joint between the calcaneus and cuboid bones on the outside of the foot.
Foot bones

A midtarsal joint sprain involves two ligaments. Each produces slightly different symptoms.

The Bifurcate ligament is Y shaped and consists of 2 parts. It spits into the Calcaneonavicular ligament and the Calcaneocuboid ligament.

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

Calcaneocuboid ligament injury

This is more likely following a sprained ankle or similar. Symptoms of a midtarsal joint sprain involving the calcaneocuboid ligament:

  • Pain on the outside middle of your foot.
  • Pain and swelling on the top and outside of your foot.
  • Inverting your foot (or turning it so the soles face inwards), may be painful.
  • Your doctor may use MRI scan to confirm the diagnosis. An X-ray rules out any fractures.

Treatment:

Rest your foot and avoid weightbearing. Apply cold therapy for 10 minutes very hour for the first 24 to 48 hours. This helps to reduce pain and inflammation.

Your doctor may prescribe NSAID’s (such as ibuprofen) to reduce pain and inflammation.

Orthotic shoe inserts help correct any biomechanical foot problems. If your symptoms persist, then a doctor may prescribe a corticosteroid injection.

Bifurcate ligament injury

This type of midtarsal joint sprain occurs after a severe ankle injury. It also occurs in conjunction with a fracture of part of the calcaneus (heel bone), called the processor prominent.

Symptoms include:

  • Pain on the outside middle of your foot.
  • Pain is worse by pointing the foot down and rolling it outwards (plantar flexing and supinating).
  • An MRI scan will confirm the diagnosis and X-rays should be done to identify fractures. In particular, the anterior process of the heel bone.

Treatment:

Immobilize your foot, possibly in a cast, for 4 weeks. Surgery may be considered if your injury is severe. And/or if bones have been displaced out of their normal positions.
