Fracture of scaphoid

leave a comment »

  • High potential for AVN to the proximal fragement (blood supply begins distally)
  • Trauma with pain over the snuff box
  • If high clinical suspicion and negative film, cast and refilm in 1 week:
  1. Diffuse osteopenia and hyperemia around the fracture site
  2. Or just get MRI
  • AVN = increased density of proximal pole of scaphoid
