PIP joint dislocation occurs when trauma causes the bones in the middle joint of a finger to dislodge. This usually results in a very painful, swollen and bruised joint that does not move properly, if at all. A sprain occurs when ligaments in a joint are torn or pulled and may occur without joint dislocation. Suspected sprains and dislocations must be evaluated and treated as soon as possible. It is important not to move the affected area to avoid further injury. Joint dislocations should be re-set into position immediately, usually in an urgent care or emergency room setting, with immediate follow-up examination. The joint will then be assessed for any fractures or residual instability that could necessitate surgical intervention.
