What are Sesamoids?

Sesamoids are bones not connected to other bones but are instead connected to tendons or embedded in the muscle. The largest sesamoid is the kneecap. Sesamoids are also found in the feet and the hands.

What is Sesamoiditis?

Sesamoids can break or fracture and the tendons surrounding the sesamoids can become inflamed or irritated. This is sesamoiditis or another form of tendonitis. This condition is common in baseball catchers, runners and ballet dancers.

Diagnosis/Examination  

History and physical exam by a qualified musculoskeletal expert is the first step. The physician will look for tenderness during the examination. X-ray or MRI scanning may be required.

Treatment

Treatment is generally non operative. Options recommended include rest and stopping the activity that caused the injury. Pain relievers or splinting may be recommended.
