21r-M/2.1 Radius, torus/buckle fracture





The majority of fractures of the proximal radius in childhood are radial neck fractures, 21r-E and 21r-M.

This injury is usually caused by a fall onto an outstretched hand. Occasionally it is caused by a direct blow.

The injury is associated with local tenderness over the proximal radius. Local swelling may be present but can be difficult to detect.

It is inherently stable (provided the tension cortex is unbroken) and will usually model out any angulation over time.
