A 24-year-old man seeks medical attention 3 weeks after he injured his little finger playingfootball. He reports that the finger “came out of place” at the middle knuckle (proximal interphalangeal[PIP] joint); he quickly put the finger back into place himself, quit playing, andiced it. About 2 hours later, he was unable tomove the finger without significant pain, andthe following day, inability to move it interferedwith his performance of tasks that requiredfine manual dexterity. Since then, thepain has decreased, but the finger remainsswollen and he has not been able to fully extendit at the middle knuckle. In addition, thetip of the injured finger is hyperextended.
