Injuries of the fingers and thumb in the athlete.

Injuries of the fingers and thumb in the athlete are common. Mallet finger, jersey finger, boutonniere deformity, Bennett and Rolando fractures, and gamekeeper's thumb are just a few of the injuries that can occur in athletes. A thorough understanding of the mechanism of injury, osseous and soft tissue abnormalities, imaging features, and treatment is important in the care of athletes. Prompt and accurate diagnosis is important and may help minimize outcomes of malunion, posttraumatic arthritis, and debility.
