ABSTRACT
PURPOSE:
The purpose of this study was to evaluate the clinical results of scaphoid nonunions treated with 1, 2-intercompartment supraretinacular artery (ICSRA) pedicled vascularized bone grafting (VBG) and headless compression screw fixation.METHODS:
Since August 1, 2005, 11 scaphoid nonunions with avascular necrosis or bone marrow edema of proximal fragments were managed with 1, 2-ICSRA pedicled VBG combined with headless compression screw fixation. The mean age was 37.1 years (range, 21-66 years). 8 patients had avascular necrosis (AVN) of proximal fragments and 3 patients had bone marrow edema in proximal fragments. Serial radiographic evaluations were performed in every 4-8 weeks for bone union and follow up computed tomography scanning were checked in 8 patients.RESULTS:
Bone unions were obtained in all 11 patients at 4.9 months (range, 3-9 months) after operation. At last follow up, the average range of motion was 82.5% and the grip power was 84.1% compared to the contralateral side. The mean New York Orthopaedic Hospital wrist score at last follow up was 83.2 (range, 58.1-93.3).CONCLUSION:
Combined 1, 2-ICSRA pedicled VBG and headless compression screw fixation were reliable methods for managements of scaphoid nonunions even with AVN at proximal fragments.
