[Fracture dislocation of the proximal interphalangeal joint]

The proximal interphalangeal (PIP) joint is the most commonly dislocated joint in the body and the hand. We did a review of the literature and report herein our experience treating this condition at the ABC Medical Center from 1991 to 2007.

Systematic review of the literature. Retrospective and descriptive study.

A total of 13 patients were included between 1991 and 2007. Three of them were managed with ORIF with Kirschner nails, 3 with OR and Kirschner nails blocking extension, 2 with plasty with volar plate interposition, and one with CRIF with a Kirschner nail. Mean follow-up was 4.8 months in 8 patients, the ranges of motion were recorded. The following factors were negatively correlated with the range of motion: age, time elapsed between the injury and the treatment, the combined approaches, and the pins blocking extension. Those treated with interposition arthroplasty had a better range of motion.

The fracture dislocation of the PIP joint is a rare pathology with multiple treatments and variable outcomes that usually result in the limitation of flexion and extension.
