Volar plate arthroplasty for closed proximal interphalangeal joint injuries.

The anatomy and histology of the volar plate at the proximal interphalangeal joint and the mechanism of fracture/subluxation of the base of the middle phalanx in closed proximal interphalangeal joint injuries is reviewed. Our current technique of repair for these injuries and its evolution from Eaton's original procedure is described. The results of 71 cases of volar plate arthroplasty performed over a five-year period for fracture/subluxations of the proximal interphalangeal joints are presented with follow-up ranging from six months to four years. 62 (87%) patients achieved a stable pain-free joint with a range of motion from 5 degrees to 95 degrees within two months. Complications were uncommon and correctable with an overall eventual patient satisfaction rate of 94%.
