Fractures of the lesser sesamoids: case series
We present 3 cases of sesamoid fractures involving the index, ring, and little finger metacarpophalangeal
joints. These injuries present similar to more common sprains of the finger metacarpophalangeal joint and may be difficult at times to appreciate on standard posteroanterior and lateral x-rays. Oblique images can aid in making the diagnosis at times. Whereas we still recommend immobilization as the initial treatment for these injuries, all 3 of our cases failed nonoperative management and eventually required sesamoid excision.
