The use of dynamic external fixation in the treatment of dorsal fracture subluxations and pilon fractures of finger proximal interphalangeal joints

The aim of this study was to review the outcome of the treatment of finger proximal interphalangeal joint dorsal fracture subluxations and pilon fractures with a modified external fixator. We treated 36 patients (36 fingers). We assessed the ranges of motion and patient satisfaction. At final follow-up, 23 patients had no pain; 11 had pain in the cold; and two also had mild pain. None had moderate or severe pain. The mean range of proximal interphalangeal joint motion was 86° (60°–100°). The mean total active range of finger motion was 244° (range 200°–265°). This system is simple, cheap and relatively easily applied. It gives stable fixation that allows early mobilization. Level of evidence: IV
