Ten consecutive patients were treated with delayed DDEF between 2010 and 2013. Postoperative ROM at the PIPJ was measured. Disabilities of the Arm, Shoulder and Hand (DASH) score and Michigan Hand Outcomes Questionnaire were administered to all patients postoperatively.
Mean time from injury to surgery was 27.5 days. The mean follow-up period was 23.7 months (range 10–36). The mean active ROM at the PIPJ on final postoperative follow-up was 83.9° (range 52–100). None of the patients experienced pin-tract infections. Mean DASH score was 3.7 + 3.4 and mean Michigan Hand Outcomes Questionnaire score was 97.3 + 3.0. All patients returned to work and resumed normal activities.
Delayed treatment of unstable PIPJ fracture-dislocations with a DDEF is effective in restoring function to the PIPJ. Nascent malunion of the PIPJ articular surface does not compromise postoperative outcomes and the joint surface undergoes remodelling over time to restore a smooth and functional articular surface.
