Sesamoiditis is inflammation of the sesamoid bones.

Humans

Sesamoiditis occurs on the bottom of the foot, just behind the

, the tendons which bend the big toe downward.

Symptoms include inflammation and pain.

Sometimes a sesamoid bone is fractured. This can be difficult to pick up on

Among those who are susceptible to the malady are dancers, catchers and pitchers in baseball, soccer players, and American football players.[2]^[3]

Horses

In the horse it occurs at the horse's fetlock. The sesamoid bones lie behind the bones of the fetlock, at the back of the joint, and help to keep the tendons and ligaments that run between them correctly functioning.

Usually periostitis (new bone growth) occurs along with sesamoiditis, and the suspensory ligament may also be affected. Sesamoiditis results in inflammation, pain, and eventually bone growth.

Causes

In humans, excessive forces caused by sudden bending upwards of the big toe,

, or a stumble can contribute to sesamoiditis. Once the sesamoid bone is injured it can be very difficult to cure, because additional pressure is put on the sesamoid bone during walking.

Treatment

Treatment in humans consists of

with special accommodations to keep pressure off the affected bone.

In horses, sesamoiditis is generally caused by excess stress on the fetlock joint. Conformation that promotes sesamoiditis include long pasterns, or horses with long toes and low heels.
