Volar Dislocated Proximal Interphalangeal Joint

History: male with finger pain. 

Dislocated proximal interphalangeal joint – Lateral radiograph of the left hand reveals complete volar dislocation of the third proximal interphalangeal joint.

This is a volar dislocation of the third proximal interphalangeal joint. Volar dislocations of the proximal interphalangeal joint are the least common and have the worst prognosis. In volar dislocation the central slip of the extensor digitorum is commonly disrupted along with the volar plate and collateral ligaments. Dorsal dislocation of the proximal interphalangeal joint is much more common than volar dislocation and has been referred to as a “Coach’s finger.”
