Sesamoiditis – Signs, Symptoms and Treatment

The sesamoid bones are bones which are held in place by tendons and muscles. These bones are found everywhere in the human body including the knee, feet, hands, wrist, neck or ear.

Sesamoid bones vary in size from one person to the other, yet, they usually are the size of a jelly bean. They are located within tendons that are located in areas where the tendons pass over joints.


The function of these sesamoid bones is to aid mechanical action of the tendons. These bones can be injured as well. The most common injury of the sesamoid bones is a bone fracture, followed by sesamoiditis.

Sesamoiditis is an inflammation of the sesamoid bones together with the surrounding tissue. The sesamoid bones of the toe are the one most inflamed after an injury. However, as mentioned, any sesamoid bone in the human body can get injured.

This is more common among those who overuse the sesamoid bones of the toes. This medical condition is more common among dancers, athletes, runners, etc. Sesamoiditis can also occur after a long hike for those who are not used in hiking.

In elderly patients, sesamoiditis can result from arthritis and arthritic changes to these bones.

Sometimes, sesamoiditis results from physical abnormalities, such as in cases when the bones are larger than normally, putting excessive force and pressure on them.

Signs and symptoms of Sesamoiditis
