American Compact Disc

Colles and Smith fractures are both fractures of the distal radius.

Colles fracture

  • Dorsal angulation of the fractured fragment
  • Memory aid: CD

Smith fracture

  • Volar angulation of the fractured fragment
    • Volar means palmar
  • Memory aid: VS almost looks like US, which is quite American

And that’s how an American CD is made.

Primary And Secondary Curvatures

The vertebral column consists of 5 regions:

  • Cervical (7 bones)
  • Thoracic (12 bones)
  • Lumbar (5 bones)
  • Sacral (5 fused)
  • Coccygeal (4 fused)

Primary curvatures

  • Develop in foetal life, before birth
    • Regions affected:
      • Thoracic
      • Sacral
    • Kyphosis
      • Spine curves posteriorly, like a hunchback appearance
      • Memory aid: the one that’s not lordosis

Secondary curvatures

  • Develop in childhood, after birth
    • Regions affected:
      • Cervical
      • Lumbar
    • Lordosis
      • Spine curves anteriorly, like a fancy, puffed out pigeon
      • Memory aid: lordosis happens later; lords are fancy people, so they stand proudly and don’t hunch their backs

Major Arm Nerves Passing Through Geometric Spaces

Quadrangular space: axillary nerve.

Remember: a is before r in quadrangular.

 

Triangular space: radial nerve.

Remember: r is before a in triangular.
