The body’s attempts to heal the area may build up extra calcium around the dead spot. Osteochondritis causes a piece of the bone to actually die. This condition is called osteochondritis. In some cases, blood supply to the sesamoid bone is decreased. This focuses strain and pressure on the sesamoids. The high arch causes the main joint of the big toe to become rigid. Arthritis is more likely to be a problem in people who have high arches in their feet. Like other joints in the body, this joint can also develop arthritis. The sesamoid bones create a joint where they move against the bone of the big toe. Athletes most often suffer stress fractures of the sesamoids because of the heavy and repeated demands that training places on the soft tissues of the foot and big toe.Īrthritis can develop where the sesamoids glide under the bone of the big toe. Stress fractures are usually caused by the strain of overworking the soft tissues. Stress fractures can also occur in the sesamoid bones. Fractures can occur when a person falls and lands bluntly on the ball of the foot. Sesamoiditis is often caused by doing the same types of toe movements over and over again, which happens in activities like running and dancing.įractures can also cause pain in the sesamoids. When the tissues around the sesamoid bones become inflamed, doctors call the condition sesamoiditis. Sesamoid pain can develop a number of different ways. The sesamoids also help absorb pressure under the foot during standing and walking, and they ease friction in the soft tissues under the toe joint when the big toe moves. This bump acts as a fulcrum point for the toe flexors, giving these muscles extra leverage and power. The muscles that bend the big toe down (the toe flexors) pass underneath the main joint of the big toe, crossing over the bump formed by the sesamoid bones.
There is one sesamoid bone on each side of the base of the big toe.
The two small sesamoid bones are located on the underside of this joint. The main joint of the big toe forms the inside edge of the ball of the foot. Where are the sesamoids, and what do they do?
If the sesamoids are injured, they can be a source of severe pain and disability. Even though they are small in size, the sesamoids play an important role in how the foot and big toe work. Two pea-sized bones, called sesamoids, are embedded within the soft tissues under the main joint of the big toe. A Patient’s Guide to Sesamoid Problems Introduction
