Finger Dislocations
Introduction
Most finger dislocations occur at the proximal interphalangeal (PIP) joint; they are usually caused by hyperextension and thus are usually dorsal. Finger dislocations can be dorsal, lateral, or volar. They may rupture various combinations of supporting ligaments. Most cause obvious deformities, as well as pain and swelling. Anteroposterior, lateral, and oblique x-rays are taken. Lateral views should be taken with the affected digit visibly separated from the others. For most dislocations, closed reduction is done after a digital nerve block is used. For all PIP dislocations, stability of the lateral ligaments is assessed by stress testing after the dislocation is reduced. (See Overview of Dislocations .)
