The aim of the present study is to present the long-term efficacy of the graft of the distal radius based on the 1,2 intercompartmental supraretinacular artery (1,2 ICSRA) for the treatment of scaphoid nonunion with a proposed treatment of double stabilization with Kirschner wires and external fixator.
Between 2007 and 2013 we retrospectively reviewed 11 patients who were operated for established scaphoid nonunion with pedicled vascularized distal radius graft based on the 1,2 ICSRA in our department. Stabilization of the graft was achieved with Kirschner wires and the wrist was immobilized with a transarticular external fixator. All patients were evaluated pre- and post-operatively both clinically and radiologically. The DASH score was also completed by the patients before and after the operation. The minimum follow-up of the patients was 5 years.
The mean age of the patients was 28.64 years (range, 18–49 years). Ten patients were males (90.91%) and one female (9.09%). In all patients, union was achieved. The mean time of union was 11.2 weeks (range, 8–18 weeks). The mean follow-up was 61.32 months (range, 60–72 months). Compared to the contralateral hand there was noticed 14° lack in flexion and 18° in extension. The mean DASH score showed also significant improvement from 23.1 (range, 9.4–50.6) preoperatively to 4.72 (range, 0–22.8) during the last follow-up.
The 1,2 ICSRA distal radius graft consists a trustworthy pedicled vascularized graft for the treatment of nonunion presenting very promising long-term outcomes.
