Cuboid Syndrome here's some info I found on the web

Cuboid syndrome refers to the disruption of the normal function of the calcaneal-cuboid joint (CC joint). Disruption of the CC joint is often called subluxation. Cuboid syndrome can be found described in the literature as a sequella of inversion sprains of the ankle. Also, cuboid syndrome is found described in dance (ballet) literature.

Cuboid syndrome is somewhat uncommon and is poorly defined in the literature. When conditions are poorly defined in the literature, this usually means that there is a lack of agreement among doctors as to the eitiology (reason for the condition) and the treatment.

Treatment Of Cuboid Syndrome

Cuboid syndrome is treated by reducing (realigning) the subluxation of the CC joint and stabilizing the reduction. Reduction of the subluxation can be accomplished by manipulating the joint. Manipulation is performed with the patient in a prone (face down) position. The practitioner cradles the foot in his/her hands and places both thumbs beneath the CC joint. The CC joint is then manipulated by a forceful movement, moving the leg at the knee and the ankle while applying pressure with the thumbs at the plantar (bottom) aspect of the CC joint.

Reduction of the subluxation can be maintained with taping, and padding. Prescription orthotics (arch supports) are helpful in preventing a recurrence of cuboid syndrome. Occasionally, cortisone injections may be helpful in reducing inflammation associated with the subluxation of the CC joint. Patients are instructed to avoid going barefoot or wearing shoes with low heels. Small (less that 1/2") heel lifts can also be helpful.

Chronic cuboid syndrome is called tarsitis (inflammation of the tarsal bones). Tarsitis results from excessive intrinsic load, often called CT band syndrome. Tarsitis is just one of many symptoms of CT band syndrome. For additional information regarding chronic cuboid syndrome (tarsitis), please read our article on CT band syndrome.

The response to treatment of cuboid syndrome depends upon the eitiology and onset of symptoms. Acute onset of cuboid syndrome, say from an ankle sprain, may respond dramatically to manipulation. If cuboid syndrome is due to chronic, excessive intrinsic load (CT band syndrome) treatment such as manipulation may be less effective and take longer to see results.

Biomechanics: these are important considerations

Cuboid syndrome occurs at the calcaneal-cuboid joint (CC joint) on the lateral or outside of the foot. The CC joint functions together with the talo-navicular joint (TN joint) and the subtalar joint (STJ) to deliver load to the forefoot. The function of these joints is to deliver load that can be converted into action; walking, running etc. For additional definitions of load in relationship to the normal function of the foot and leg, please refer to our article on CT band syndrome.

Cuboid syndrome occurs when the calcaneal-cuboid joint is unable to carry the load that is applied to it. The result is that the calcaneal-cuboid joint subluxes (moves out of its' normal position).
