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.

2
: inflammation of the navicular bone and adjacent structures in the horse
