Complete oblique or spiral fractures are inherently unstable.
Isolated complete radial shaft fractures with an intact ulna are rare.
An isolated radial fracture with substantial deformity is likely to be caused by rotational trauma leading to forced supination or pronation.
Note: Always consider distal radioulnar joint dislocation (Galeazzi injury) especially in the older child.
