Most finger dislocations occur at the middle joint. But they may occur at other finger joints. They usually occur when the finger is bent backward, as may occur when a basketball or baseball strikes the tip of an outstretched finger. But they may occur when the finger is bent sideways or forward.
The ligaments that hold the finger bones together may be torn. If a finger bone is pulled away from tendons attached to it, a piece of bone may be broken off and stay attached to the tendon (called an avulsion fracture).

Treatment of a Dislocated Finger
To treat most finger dislocations, doctors inject an anesthetic into the base of the affected finger, and the finger bones are put back in place (called reduction).
Usually, reduction is done without surgery (closed reduction). However, surgery may be required—for example, when
After the joint is put back in place, doctors also gently move the finger in different directions to determine how badly the ligaments are damaged. Usually, a splint is applied and is typically worn for about 3 weeks.
