medical Definition of sesamoiditis
1
:pain and inflammation of either of the two small sesamoid bones or surrounding tendons of the ball of the foot at the base of the big toe
- The pain is increased when the first metatarsophalangeal joint is dorsiflexed to its limit. However, the diagnosis of a sesamoid stress fracture should not be based on the above history and physical findings alone. Athletes with a sesamoiditis or a metatarsalgia can present with a similar symptom complex.
- —James S. Keene, The Journal of the American Medical Association, 11 July 1986
