Torus Fracture / Platic Deformation

- Discussion:
    - torus is derived from Latin (tori) meaning a swelling or protuberance;
    - failure of cortex on compression side, 2-3 cm proximal to physis;
    - torus (buckle) frxs of distal metaphysis of radius & ulna is most common frx in lower forearm in young children;
    - impact of indirect violence of fall on outstretched hand crumples dorsal cortex, but the volar cortex remains intact;
    - distal fragment is angulated dorsally;
    - deformity should not occur in torous frx because the periosteum and cortex are intact on the side of the bone opposite to fracture;

- Radiographs:
      - it is important that x-ray be carefully examined to ascertain that tension side is intact;
      - if frx is not on compression side then pt has greenstick frx, not a torus frx, & frx may proceed to deform in the cast;


- Treatment:
    - consists of short arm cast for 3 weeks to make pt comfortable and to prevent further injury
