Mallet Finger
Baseball Finger is a condition that happens when a sudden blow to the fingertip damages the thin extensor tendon that serves to straighten the fingers. Common in sports like baseball and softball, the condition is indicated by mild pain, bruising and swelling as well as an inability to straighten the fingertip.
Baseball Finger is normally treated by splinting the tip of the finger in question for a period of 6 to 8 weeks. Surgery is usually unnecessary.
