Cuboid Syndrome is a condition in the foot which is commonly poorly recognised and often underdiagnosed. It is not very common, making up lower than 5% of foot conditions. In this condition the cuboid bone is thought to become partly subluxed because of too much traction from peroneus longus tendon which passes around the bone. When a foot is overpronated it is assumed that the cuboid isn't a stable as a pulley once the peroneus longus muscle fires. Because of this the outside part of the cuboid bone is pulled dorsally and the medial part is pulled plantarly. This is more of an overuse type of injury, although the cuboid can also become subluxed as part of an immediate lateral ankle sprain.
Clinically, there is outside foot pain on weightbearing, usually situated around the calcaneocuboid joint and cuboid-metatarsal joints. This could start as vague lateral foot pain. Pressing the cuboid bone upwards from underneath the foot can produce the symptoms and frequently the range of motion is restricted compared to the other side. There have been no x-ray information connected with cuboid syndrome. There are a number of other disorders that can mimic cuboid syndrome, such as sinus tarsi syndrome, a stress fracture or peroneal tendonitis. It is also considered a common symptom following plantar fascia surgical release for recalcitrant plantar fasciitis.
Management of cuboid syndrome starts off with activity changes, to ensure that activity levels are limited to what can be tolerated. Ice can be used to assist with the initial pain relief. Strapping to immobilize the area is also a excellent first line approach, generally this is followed by foot supports to help stabilize the cuboid bone. There is a specific mobilization that is useful in cuboid syndrome to handle the subluxation, though there is some debate around this method as to just what the manipulation is doing.
