The purpose of this prospective study was to correlate preoperative gadolinium-enhanced MRI scans with intraoperative bleeding of the proximal fragment and postoperative union in a series of consecutive patients with established scaphoid nonunions. In 60 patients (6 females, 54 males) with a mean age of 29 years, scaphoid perfusion was judged preoperatively as normal, impaired or absent using a gadolinium-enhanced MRI scan. Scaphoid reconstruction was performed using a nonvascularized bone graft and screw fixation. Perfusion of the proximal fragment was assessed intraoperatively in 49 of 60 patients; compromised or absent vascularity was predicted with a specificity of 90% by contrast-enhanced MRI. However, there was no significant correlation between preoperative MRI assessment of vascularity and subsequent union of the scaphoid.
