Sesamoid foot problems in the athlete.

Problems of the sesamoid bones of the metatarsophalangeal joint of the great toe are critical in maintaining full ability to compete or to engage in recreation--in athletes of any age. The sesamoids are subject to the same post-traumatic, acute, and chronic changes as any other bone. These unique and deceptively important injuries demand a high index of suspicion, a thorough diagnostic effort, and a guided long-range treatment program, including follow-up to normalized athletics, particularly in the running-based sports.
