Cuboid Syndrome

Cuboid Syndrome

Cuboid syndrome occurs when the peroneus longus muscle in the lower leg applies excess traction onto the cuboid bone, causing it to partially dislocate. The injury often occurs in conjunction with peroneal tendonitis and overpronation. Pain increases as weight is placed on the foot and medical help is needed to correct the foot injury.

Cuboid syndrome symptoms

Symptoms of cuboid syndrome are very similar to that of an ankle sprain and include pain on the outside of the foot when bearing weight.

Pain is worse when weight is transferred onto the foot and many patients with this condition will significantly overpronate (where the feet roll in or flatten).

The Cuboid bone is one of 8 tarsal bones in the rear and mid-foot. It is located on the outside of the foot, just in front of the ankle. The partial dislocation occurs at the calcaneocuboid joint, between the heel bone (calcaneus) and the cuboid in front. Cuboid syndrome usually occurs after a significant ankle inversion sprain, although it can happen when no other injury has occurred.

Cuboid syndrome treatment

The cuboid bone is physically manipulated or reduced back into position by a doctor, medical professional or surgeon. The reduction of the joint position can be maintained using taping and padding, as well as the use of arch support insoles. Corticosteroid injections are sometimes used.

If peroneal tendonitis is a contributing factor, then this will need to be treated with rest, ice and a gradual rehabilitation program of stretching and strengthening exercises. Particularly if the peroneal muscles are tight and causing the excess traction on the cuboid bone, then stretching exercises and deep tissue massage are important.
