There are some bones in the body that are connected to tendons or embedded in muscles rather than connected to other bones. These are referred to as sesamoids.

The foot has two sesamoids. In the normal foot, the sesamoids are two pea-shaped bones located in the ball of the foot, beneath the big toe joint. The sesamoids acts as a pulley for the tendon and help the big toe move normally and provide leverage when the big toe pushes off during walking and running.  However, like bones they can fracture, or cause surrounding tendons to become irritated and inflamed. This is called sesamoiditis and is a form of tendinitis.

What are the Symptoms of Sesamoiditis?

Sesamoiditis can be identified by the gradual development of pain under the big toe on the ball of the foot. This may or may not be accompanied by swelling. A fracture, on the other hand is met with pain immediately.

In addition to the above, bending and straightening of the big toe can be difficult and painful. If you have any of these symptoms, it is advised to seek advice from your Podiatrist.

How is it Diagnosed?

A Podiatrist will look for tenderness of the sesamoid bones and will straighten, bend and manipulate the bone to check if the pain worsens. This is often followed by a set of X-rays of the foot to identify if there is a fracture and make an appropriate diagnosis.
