Cuboid Syndrome is a condition in the foot which is often poorly recognised and often underdiagnosed. It's not common, making up less than 5% of foot injuries. In this condition the cuboid bone is believed to become slightly subluxed due to excessive traction from peroneus longus tendon as it passes under the bone. When a foot is overpronated the assumption is that the cuboid is not a stable as a pulley when the peroneus longus muscle fires. As a result the lateral side of the cuboid bone is moved upwards and the medial part is pulled plantarly.
This is really an overuse type of injury, however the cuboid might also become subluxed as part of an immediate lateral ankle sprain.Usually, there is lateral foot pain when standing, usually situated over the calcaneocuboid joint and cuboid-metatarsal joints. This can present as vague lateral foot pain. Pushing the cuboid bone dorsally from underneath the foot can produce the pain and typically the range of motion is reduced when compared to the opposite side. There have been no x-ray information associated with cuboid syndrome. There are a number of other conditions that may mimic cuboid syndrome, for example sinus tarsi syndrome, a stress fracture and peroneal tendonitis. It is also regarded as a common symptom following plantar fascia surgical release for recalcitrant plantar fasciitis.
Dealing with Cuboid Syndrome starts off with exercise changes, making sure that exercise amounts are limited to what can be tolerated. Ice can be used to assist with the initial pain relief. Strapping to immobilize the foot is also a excellent first line approach, commonly this is followed by foot supports to help support the cuboid bone. There is a distinct mobilization which is useful in cuboid syndrome to deal with the dislocation, even though there is some discussion around this approach as to precisely what the adjustment is affecting.
