Purpose: Aim of the present study was to evaluate the clinical, functional, and radiological outcomes of 1,2-intercompartmental supraretinacular artery (1.2-ICSRA) vascularized graft technique together with compression screw fixation for the management of scaphoid nonunions. Methods: A retrospective study was designed to evaluate the medical records of the 21 patients treated with 1,2-ICSRA vascularized graft for established scaphoid nonunion of the waist or proximal pole between 2015 and 2018. Seventeen patients who met the criteria were included in the study. The retrospectively analysed demographic parameters included age, gender, injured hand (dominant/non-dominant), aetiology of the injury, delay between injury and operation, initial treatments following the fracture, tobacco use, and background diseases that may affect healing (diabetes, vasculopathy etc.). Radiological and clinical examinations were routinely performed 2 weeks, 6 weeks, 3 months and 6 months after surgery and during the final follow-up. Postoperative clinical and functional outcomes at the latest follow-up were evaluated by measuring active wrist range of motion, grip strength, Turkish version of Quick Disabilities of the Arm, Shoulder and Hand Questionnare (Quick DASH) and Mayo Wrist scores and comparing them with preoperative values. Results: All 17 patients were male with an average age of 26.82 +/- 4.08 years (range 20-35 years). The fracture site was located in the scaphoid waist and proximal pole in 5 (29.4%) and 12 (70.6%) patients, respectively. Avascular necrosis was observed in 13 patients (2 at the waist, 11 at the proximal pole). The mean follow-up duration was 18.88 +/- 11.98 months (range 6-44 months). No graft extrusion occurred, and no other complication was observed in any of the patients. Amongst the 17 patients, 15 (88.2%) achieved union. The total wrist motions of patients were better postoperatively than preoperatively. However, only improvement in wrist extension was found to be statistically significant. Quick DASH and Mayo Wrist scores of the patients and grip strength were significantly improved postoperatively. Conclusion: The 1,2-ICSRA vascularized graft technique together with compression screw fixation offers an easy and reliable option for the treatment of scaphoid nonunions with a high union rate and good functional and clinical outcomes.
