Sesamoiditis

Sesamoiditis is a condition in which the sesamoid bones of the foot and their surrounding tendons become inflamed. The sesamoids are two small, pea-shaped bones located in the ball of the foot, just under the big toe joint. These bones aid in moving the big toe normally, allowing it to be used to push off while walking or running. The sesamoids also absorb the weight placed on the ball of the foot during walking, running, and jumping activities. 

Sesamoiditis is typically the result of overuse. Repetitive activities that put excess pressure on the sesamoid bones, such as jogging, can cause inflammation in the sesamoid bones and surrounding tendons. Symptoms of sesamoiditis include dull, chronic pain beneath the big toe joint, swelling, bruising, and difficulty bending and straightening the big toe. 

Sesamoiditis is typically diagnosed based on medical history and a physical examination. Sometimes imaging studies, such as X-rays, may be ordered to rule out any fractures. Treatment for sesamoiditis is conservative and usually involves padding, strapping, taping, or immobilizing the affected toe to reduce pressure and pain on the toe. Resting the affected toe is essential to ensure healing. Nonsteroidal anti-inflammatory medications or steroid injections can also be used to reduce pain. Orthotic devices may be prescribed to cushion the balls of the feet while walking. To learn more about sesamoiditis, please consult with a chiropodist.
