Cuboid Syndrome
Cuboid syndrome occurs when the peroneus longus applies excess traction onto the cuboid bone causing it to sublux (partially dislocate). The injury is often associated with peroneal tendinopathy.
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 has been reported when no other injury has occurred.
Symptoms of Cuboid Syndrome
- Symptoms are very similar to that of an ankle sprain.
- Pain when weight bearing on the outside of the foot.
- Pain is worst when weight is transferred onto the foot
- Many patients with this condition will significantly overpronate (feet roll in or flatten)
Treatment of Cuboid Syndrome
- The cuboid bone is physically manipulated (reduced) back into position.
- The reduction of the joint position can be maintained using tapinf and padding, as well as the use of arch support insoles.
- If peroneal tendonitis is a contributing factor then this will need to be treated.
- Corticosteroid injections are sometimes used.
