MedPix® Patient Chart - Case No: 8695 :: - Review Images

a 6 year old girl fell out of tree, now she has pain in her left wrist.

• Pain and swelling over left forearm.

- Review Images for PT: 8695

Radiographs of the left wrist demonstrate two fractures:
• a Torus (buckle) fracture of the distal ulna. There is radial angulation of the distal portion of the ulnar Torus (buckle) fracture.

• a Greenstick fracture of the distal radial diaphasis, with anterior angulation of the distal radius.

In the immature skeleton the bones are more pliable. This is partly due to more Haversian Canals within a greater percentage of the cortex and partly due to less complete mineralization of immature cortical bone. This also explains why children have more incomplete fractures than adults.
   
Examples of incomplete fracture types include:
» Torus (buckle) Fracture, which results from a force insufficient enough to produce complete cortical discontinuity but instead cause a buckling of the cortex (this is a plastic bending of the bone, which causes deformation of the bone). Torus fractures may occur on the opposite side of a Greenstick fracture (a greenstick fracture is one wherein only one side of the bone has a true linear fracture lucency, but the fracture line does not continue across the entirety of the bone. Torus fractures most commonly occur in the metaphyseal and diametaphyseal regions.

» Greenstick Fracture: Fracture of only one side of the cortex. Fracture is on the convex side with a "bend" on the concave side.
      
» Bowing (plastic) Type: A plastic response to a longitudinal stress in a bone. There is no obvious break in the cortex.
