To compare the radiographic and functional outcomes of 2 surgical techniques for treating scaphoid nonunion.
Randomized prospective study.
Researchers assessed the outcomes every 2 weeks until bone healing and at discharge.
(1) Vascularized bone grafting (VBG) using the 1, 2 intercompartmental suprareticular artery and (2) a distal radius nonvascularized bone graft.
Time to union (primary), union rate, and functional outcomes.
Seventy-five patients were followed for 29 months; 2 were lost to final follow-up. Both groups had similar baseline characteristics. The VBG group reached bone union earlier by 12 days (P = 0.002), but union rates were similar (P = 0.312). There was also less ulnar deviation in the VBG group (P = 0.03). There were no other differences between either intervention groups.
Although the VBG group attained earlier union, this may not be clinically meaningful, nor justify the greater technical difficulty and use of resources associated with this intervention.
