What is Sesamoiditis?
The Sesamoid bones connect to muscles in the foot by tendons. They differ from most bones in the body, which only connect to each other at the joints. Sesamoiditis occurs when the tendons attached to sesamoids inflame and cause pain.
The kneecap is actually the largest sesamoid in the body. Two other much smaller sesamoids sit on the bottom of the foot near the Hallux, or big toe. Sesamoiditis usually refers to the inflammation of the tendons in the foot, not the knee. Physicians usually categorize Inflammation of the tendons attached to the kneecap — patellar tendon and quadriceps tendon — as tendinitis rather than Sesamoiditis.
Sesamoiditis commonly occurs among athletes and dancers. The condition usually stems from straining or overworking the connecting tendons. Rest and anti-inflammatory medications usually treat Sesamoiditis effectively.
What are the symptoms?
In patients suffering from sesamoiditis, pain develops under the ball of the foot. The pain tends to gradually build, and may also induce swelling or bruising.
Sesamoiditis makes it difficult to bend or straighten the big toe. It may even cause pain to move the toe. You may also have a “popping” sensation in the big toe when you walk.
What Causes Sesamoiditis?
Sesamoiditis results from the overuse of the tendons involved with the small bones in the foot. Experiencing repeated trauma to the tendons, such as wearing high heels or poorly fitted shoes can also cause inflammation.
If patients engage in activities that place a lot of pressure on the ball of the foot have a higher risk of developing Sesamoiditis. Patients who partake in Basketball, Running, and ballet commonly develop sesamoiditis.
