Cuboid syndrome is a common problem on the lateral side of the foot

Cuboid Syndrome is a problem of the foot which is frequently poorly recognised and quite often underdiagnosed. It's not common, making up less than 5% of foot problems. In this problem the cuboid bone is presumed to become slightly dislocated from too much traction from peroneus longus tendon which passes around the bone. Whenever a foot is overpronated it is assumed that the cuboid isn't a stable as a pulley when the peroneus longus muscle contracts. As a result the outside aspect of the cuboid bone is moved dorsally and the medial part is pulled plantarly.

This problem is more of an overuse type injury, however the cuboid could also become partially dislocated as part of an acute lateral ankle sprain.Typically, there is lateral foot pain on standing, usually located over the calcaneocuboid joint and cuboid-metatarsal joints. This may present as vague outside foot pain. Pushing the cuboid bone dorsally from under the foot can create the symptoms and frequently the range of motion is restricted compared to the opposite side. There have been no x-ray information related to cuboid syndrome. There are a variety of other disorders that may mimic cuboid syndrome, including sinus tarsi syndrome, a stress fracture or peroneal tendonitis. It is also considered a frequent symptom following plantar fascia surgical release for recalcitrant plantar fasciitis.

The treatment of cuboid syndrome starts off with activity changes, making sure that activity amounts are limited to what can be tolerated. Ice can be used to help with the early pain relief. Taping to immobilize the cuboid is another excellent first line approach, typically this is followed by foot supports to help stabilize the cuboid bone.
