A closed method is recommended for the treatment of a common injury of the proximal interphalangeal joint, a fracture of the articular surface of the middle phalanx with dorsal dislocation or subluxation. The method uses extension-block splinting (a forearm gauntlet with a dorsal extension along the finger) which allows early active flexion of the proximal interphalangeal joint but prevents extension beyond a predetermined point at which the joint subluxates on dislocates. The method is described and the results in seventeen patients are presented.
