One hundred and twenty-two patients with unstable scaphoid waist fracture non-union without avascular necrosis were randomized to receive fracture fixation with Kirshner wires (K-wires) (n=61) or a Herbert screw (n=61). The outcomes of interest included pain on a Visual Analog Scale (VAS), range of motion and grip strength as a percentage of the healthy side, the Quick Disability of the Arm, Shoulder and Hand (QuickDASH) score, scapholunate angle, radiolunate angle, carpal height index, lateral intrascaphoid angle, time to union, time to K-wire removal, time to return to work, and the incidence of adverse events. The mean follow-up period was 34-35 months post-operation. Results revealed no statistical significant differences in all outcomes between the two groups (p>0.05 for all).
