The human body consists of more than 200 bones. Most of these bones are connected to one other at the joints. However, there are some bones that do not share any connections with other bones. Instead, these bones are connected to the tendons only or are effectively embedded in the muscles. These bones are referred to as sesamoids. One example of such a bone is the patella or kneecap, which is the biggest sesamoid in the body. There are also two small sesamoids located on the underside of the forefoot just near the big toe. Each of these sesamoids has got a distinct function of their own. The sesamoids in the body often function as pulleys. These usually provide a smooth surface on which the tendons can slide. This makes it easier for the tendons to effectively transmit the muscle forces. Sesamoids present in the forefoot can help with weight bearing as well as help to elevate the bones present in the big toe. Just like the other bones, the sesamoids can also develop fractures and break. In addition, tendons which surround the sesamoids may become inflamed or irritated in a process known as sesamoiditis. Sesamoiditis is classified as a major form of tendinitis. The condition is frequently found in ballet dancers, professional athletes and runners. The most common symptoms associated with sesamoids include pain, swelling and bruising. The majority of the pains are felt on the underside of the big toe right on the ball section of the foot. If a person is affected by sesamoiditis, the pain may develop gra
