Presentation
Young child presented with pain in wrist and h/o fall on out stretched hand.
Patient Data
Subtle buckling of cortex is seen at the distal end of radius, seen as a small protuberance on the frontal view, imaging features are suggestive of torus or buckle fracture.
Case Discussion
A 'torus' or 'buckle' fracture is the term applied for a fracture of the cortex on the non-compressive side of the bone with an intact cortex on the tension side. Torus is derived from Latin (tori) meaning a swelling or protuberance. Deformity should not occur in torus fracture because the periosteum and cortex are intact on the side of the bone opposite to fracture.
Distal end of radius featured in the image, is the most common site for a torus fracture.
