Pain under the ball of the first toe joint

Related Information Sheets

... also known as Sesamoiditis

Do you ever suffer from pain under the ball of the first toe joint?

If you do, then you could have a condition know as sesamoiditis.

Sesamoid literally translates from a Latin word meaning seed, which is the shape of these two small bones in your foot. Located inside a tendon which lies under the first toe joint, these sesamoid bones serve a very important function during walking and running.

Much of the load transfer which occurs during the propulsive phase of walking and running is transmitted through the first toe joint, which is why it is larger and more robust than the other toe joints in your foot. In order for this weight transmission to occur effectively, adequate leverage is required. The sesamoid bones help provide this much needed leverage force, hence their strategic position under the first toe joint.

If this mechanical load or the timing it occurs is incorrect, then these little bones can become inflamed, and hence the condition sesamoiditis occurs.

For further information on other causes of this condition and treatment modalities, please see our Acrobat pdf information sheet on Sesamoiditis which is available on our website.
