A mallet finger injury occurs when the tip of a finger or the thumb is forcefully flexed.  The force injures the tendon that straightens the fingertip joint.  A mallet finger injury is also referred to as a baseball finger injury because it commonly occurs during the sport of baseball. 

A mallet finger injury causes loss of movement, pain, and swelling.  The joint at the end of the finger is noted to droop.  Most mallet finger injuries are treated with splinting.  In cases of fracture or malalignment, surgery may be necessary to treat the condition.
