Other Names: Drop Finger, Baseball Finger, Hammer Finger
What it is: Inability to staighten the tip of the finger following trauma.
Cause: This is usually due to the rupture of the extensor tendon which acts like a cable and pulls the tip of the finger up to straighten it. The
ruptured tendon can pull out (avulse) a fragment of bone from the joint. Stiffness or arthritis may result.
Treatment: Most cases can be treated by splinting. The key to this treatment is completely uninterrupted use of the splint for a period of four
to eight weeks depending on the extent of the injury. Do not remove your splint for any reason. Occasionally, this treatment fails and
surgery may be indicated.
