Background: The aim of this study was to observe efficacy and outcomes of 1,2 inter compartmental supraretinacular artery(ICSRA) pedicle vascularized bone graft in scaphoid non-union at our center. Methodology: This retrospective study was conducted over a four-year period from January2015 till January 2019. All patients who underwent 1,2 ICSRA pedicle vascularized bone graft for scaphoid non-union were included in the study. The vascularized grafts were fixed with k-wires and compression screws. The outcome was measured by radiological healing time, range of motion at the wrist joint, and grip strength of hand, and the DASH (Disability of the Arm, Shoulder and Hand) score. Results: 13 patients underwent 1,2 ICSRA pedicled vascularized bone graft for scaphoid non-union. According to the topography of fracture, 9 were proximal pole fractures and 4 were waistline fractures. 11 out of 13 patients achieved radiological healing by a mean time of 9.8 weeks. There was a significant decrease in the DASH score from 77.3 to 25.1. All scaphoid unions were pain-free. The range of movement at the wrist joint was comparable to the contralateral hand.
Conclusion: Treatment of scaphoid non-unions with 1,2 ICSRA pedicled vascularized bone grafts has favorable outcomes in terms of quicker healing and better hand function.
