The modified criteria of Lee et al for radiological fusion.

GradeDescription

Definitive fusionDefinitive bony trabecular bridging across the graft-host interface, no movement (<3°) on a flexion-extension radiograph and no gap at the interface
Probable fusionNo definitive bony trabecular crossing, but no detectable movement and no identifiable gap at the interface
Possible pseudarthrosisNo bony trabecular crossing, no movement, but identifiable gap at the interface
Definite pseudarthrosisNo traversing trabecular bone, definitive gap, and movement >3°
