How serious is a buckle fracture of the radius ?

Usually not bad: The term buckle describes a break in that forearm bone that is impacted (jammed together) and usually not moved much. They generally do well with a cast or splint. In a growing child there can be other issues. If there is angulation (bending) it may need setting (manipulation). See an orthopedic surgeon or hand specialist.

Not so: A buckle fracture in a child is a fracture but the xray shows the bone is distorted slightly much like as if a can we to buckle out rather than indent if loaded. These fractures hurt but are stable. Casting may be offered for ease of treatment, immobilzation makes it feel better and the fracture typically heals uneventfully.

Not too serious: a buckle fracture is generally a non displaced fracture but it still should be immobilized for 6 weeks

Not: It is typically not serious and should do well with nonoperative management typically.
