Cuboid Syndrome is a disorder of the foot which is frequently badly recognised and quite often underdiagnosed. It is not common, making up lower than 5% of foot problems. In this condition the cuboid bone is assumed to become partially subluxed as a result of too much traction from peroneus longus tendon that passes around the bone. Whenever a foot is overpronated it is assumed that the cuboid isn't a stable as a pulley once the peroneus longus muscle fires. As a result the lateral part of the cuboid bone is drawn upwards and the medial aspect is pulled plantarly.
Cuboid Syndrome is more of an overuse type injury, however the cuboid can also become subluxed as part of an acute lateral ankle sprain.Usually, there is outside foot pain when weightbearing, generally found around the calcaneocuboid joint and cuboid-metatarsal joints. This tends to present as vague outside foot pain. Pushing the cuboid bone dorsally from below the foot can produce the symptoms and frequently the range of motion is reduced compared to the opposite side. There have been no x-ray observations regarding cuboid syndrome. There are a number of other disorders which could imitate cuboid syndrome, including sinus tarsi syndrome, a stress fracture or peroneal tendonitis. It is also regarded as a frequent symptom following plantar fascia surgical release for chronic plantar fasciitis.
The management of cuboid syndrome starts off with activity modification, to ensure that activity amounts are limited to what can be tolerated. Ice may be used to assist with the early pain relief. Taping to immobilize the foot is another good first line strategy, typically this is followed by foot orthotics to help stabilize the cuboid bone. There is a distinct manipulation that is helpful in cuboid syndrome to deal with the subluxation, even though there is some discussion around this approach as to exactly what the mobilization is achieveing.
