Abstract: Objective　To investigate the feasibility and evaluate the clinical efficacy of reconstructing scaphoid nonunion using a first and second intercompartmental supraretinacular artery (1,2 ICSRA) vascularized graft.　Methods 　The CT data of 47 patients with normal wrist joint were collected, and the distance from the tip of styloid of radius to the distal and proximal poles of the long axis of scaphoid were measured and compared with the length of vascular pedicle of 1,2 ICSRA to analyze the feasibility of 1,2 ICSRA vascularized graft for reconstruction of scaphoid nonunion. Twenty-three patients with scaphoid nonunion were treated with 1,2 ICSRA vascularized graft and Herbert screw internal fixation, and the healing of the fracture of patients were followed up and the postoperative efficacy of patients were evaluated by Cooney wrist score.　Results　The average distance from the tip of styloid radius to the proximal and distal poles of the long axis of scaphoid were (15.66±1.89) mm and (17.07±1.60) mm, respectively, which were much less than the length of vascular pedicle of 1,2 ICSRA. The mean follow-up duration was（51.08±11.30）months after the surgery for 23 cases, and bone union was achieved in all patients. At the last follow-up, the pain of wrist completely disappeared in 21 cases, and 2 cases felt slightly pain when they overworked, but the symptom of these patients were significantly improved. Cooney wrist score improved significantly from (62.39±7.21) points before the operation to（92.39±4.23）points at the last postoperative visit, and the difference was statistically significant (t=17.213，P=0). According to Cooney wrist score, the results were rated as excellent in 20 cases, good in 3 cases.　Conclusions 　1,2 ICSRA vascularized graft can cover any part of scaphoid, so this method is feasible. 1,2 ICSRA vascularized graft is an effective treatment for patients with scaphoid nonunion.
