"If the bending bone is angulated slightly beyond its limit of bending, there is a complete failure of the convex cortex (the side of maximal tension) and only bending on the compression side. These greenstick fractures are far less common than torus fractures and are often more complete than initial radiographs demonstrate. Greenstick fractures tend to be mid-shaft injuries and may result from direct perpendicular trauma."

"With greater force, the loaded bone undergoes plastic deformation, resulting in clinically evident and radiographically proven bowing of the bone; a bowing fracture. No discrete fracture is visible."
"If more force were applied the concave side of the bending bone will undergo compression fracture and a bulge will appear; a torus fracture. These usually occur in the metaphyseal regions, especially of the distal radius."
