Incomplete fracture: Macroscopic fracture line does not traverse entire bony diameter
Pediatric bones more elastic than adult bones
Greater propensity to bow or bend before breaking
Greenstick fracture: Discrete fracture line on tension side does not extend through opposite cortex
Appearance of bent immature tree branch ("green stick")
Plastic deformation: Smooth but accentuated bending of shaft without visible fracture line
"Bowing fracture"
Buckle fracture: Focal outward bulge of cortex (without frank interruption) on compression side; cortex usually intact on tension side
"Torus" term no longer in favor (as it implies circumferential bulging)
Incomplete fracture with cortical disruption: Frank cortical disruption/angulation on compression side
