Thirty-eight fingers in 27 patients with Dupuytren’s contracture of the proximal interphalangeal joint (PIPJ) in excess of 70° were treated using a staged technique. The first stage involved applying a mini external fixator across the PIPJ for continuous extension over 6 weeks with intensive hand therapy to maintain mobility of the joint and help correct the deformity. Twice weekly during hand therapy sessions the tension of the elastic band across the mini ex-fix was increased, allowing that full active flexion of the PIPJ against the elastic band could still be achieved. The second stage, 4 weeks after the external fixator was applied, involved an open palm technique of fasciectomy for the contracted cords restricting metacarpophalangeal joint movement and dermofasciectomy with full-thickness skin grafting over the proximal phalanx for bands restricting PIPJ movement. The external fixator was used to maintain active extension force until the graft healed. It was generally removed in the outpatient clinic under ring block 2 weeks after the second stage procedure. The patients were followed for a mean of 20.6 (6–48) months. The mean preoperative PIPJ deformity improved from 75° to 37° postoperatively. Overall, 69% of results were rated as good to excellent. Only one patient reported any on-going functional problems. There were eight cases of pin site infections and one case each of loose pins, osteoarthritics at the PIPJ, reflex sympathetic dystrophy, and disease recurrence needing PIPJ fusion. We conclude that our simple staged procedure is a valid alternative in the management of severe Dupuytren’s PIPJ contracture.
