Diagnose, Treat & Walk Pain-Free Again
Sesamoids are the only bones in the body that are not connected to another bone, but rather solely connected by tendons or embedded in a mass of muscle. There are three sesamoids: the kneecap, which is the largest, and two small, pea-sized sesamoids located on either side of the big toe. Because of sesamoids’ unique no-bone-to-bone contact characteristic, they act like pulleys, increasing the tendons’ abilities to transmit muscle force, assist with the foot’s ability to bear weight, and elevate the bones of the big toe.
Sesamoiditis is a form of tendonitis where the tendons surrounding the sesamoids become irritated or inflamed, caused by fracturing of the sesamoid bones, rupturing its accompanying tendons, or incessantly bearing increased stress.
Marked by dull, intensifying pain beneath the big toe, this condition makes it difficult and painful for the big toe to push off while an individual is running or walking, and reduces the strength of the foot—lessening its weight-bearing potential and causing an affected individual discomfort.
