Anatomy coverage

Both AC joints with comparable spacing.

Tech pearls

  • Weights should be 5–10 lb per side, attached to wrists (NOT held).
  • Always do bilateral for comparison.

Image evaluation

  • Both AC joints comparable, no rotation
  • Weighted view shows widening if ligament tear

Common mistakes

  • Patient holds the weights — they must hang from the wrists.
  • Including too much chest
