Single-stage distraction correction for neglected dorsal fracture dislocations of the proximal interphalangeal joint: a report of eight cases.

Abstract

We present the outcome of treatment of eight chronic neglected dorsal fracture dislocations of the proximal interphalangeal joint treated with a single-stage ligamentous distraction using the Penning mini-external fixator and a closed reduction. The distraction correction and 2 to 3 mm over distraction was performed acutely at the time of operation in all eight cases at an average injury-to-surgery time of 6 weeks. Satisfactory results with an average range of motion of 79 degrees were obtained at an average follow-up of 20 months. This technique is simple, effective and offers the advantage of being minimally invasive. We recommend this single-stage distraction correction technique for the treatment of chronic neglected dorsal dislocations of the proximal interphalangeal joint, which are no more than 10 weeks-old.
