On the outer side of the foot in front of the heel, lies the cuboid bone. This cube-shaped structure helps connect the foot to the ankle, provides the feet with stability, and helps dissipate the mechanical force it bears while walking and standing. The cuboid bone can become dislocated, which is known as cuboid syndrome, or cuboid subluxation. This can occur as a secondary injury of a sprained ankle, excessive strain on the area, or if the foot rolls inward repetitively. Flat feet and osteoporosis can also contribute to an occurrence of cuboid syndrome. Cuboid syndrome can cause pain, tenderness, redness and swelling on the outside of the foot, and it may be difficult to move the ankle. Maintaining a healthy body weight, stretching before any physical activity is undertaken, and wearing properly fitted shoes can all reduce the risk of cuboid syndrome occurring. Check with a podiatrist for additional preventative methods, or to have the condition properly diagnosed and treated.
Cuboid syndrome, also known as cuboid subluxation, occurs when the joints and ligaments near the cuboid bone in the foot become torn. If you have cuboid syndrome, consult with one of our podiatrists from In Motion Foot and Ankle. Our doctors will assess your condition and provide you with quality foot and ankle treatment.
Cuboid syndrome is a common cause of lateral foot pain, which is pain on the outside of the foot. The condition may happen suddenly due to an ankle sprain, or it may develop slowly overtime from repetitive tension through the bone and surrounding structures.
The most common causes of cuboid syndrome include:
- Injury – The most common cause of this ailment is an ankle sprain.
- Repetitive Strain – Tension placed through the peroneus longus muscle from repetitive activities such as jumping and running may cause excessive traction on the bone causing it to sublux.
- Altered Foot Biomechanics – Most people suffering from cuboid subluxation have flat feet.
A common symptom of cuboid syndrome is pain along the outside of the foot which can be felt in the ankle and toes. This pain may create walking difficulties and may cause those with the condition to walk with a limp.
Diagnosis of cuboid syndrome is often difficult, and it is often misdiagnosed. X-rays, MRIs and CT scans often fail to properly show the cuboid subluxation. Although there isn’t a specific test used to diagnose cuboid syndrome, your podiatrist will usually check if pain is felt while pressing firmly on the cuboid bone of your foot.
Just as the range of causes varies widely, so do treatments. Some more common treatments are ice therapy, rest, exercise, taping, and orthotics.
