| 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. |
