Painful Clicking of the Thumb Interphalangeal Joint Caused by a Sesamoid Bone: A Report of Three Cases

Painful clicking of the interphalangeal joint of the thumb caused by a sesamoid bone is rare. We present 3 cases of painful thumb interphalangeal joint clicking with motion, all following hyperextension injuries. No other source of symptoms was determined, and in each instance the sesamoid was removed. All patients were clinically assessed at 2 years after surgery and were noted to have relief of pain and clicking with full recovery of strength and activities.
