Scotty dog sign – refers to the normal appearance of the lumbar spine posterior elements when seen on oblique views:

  • the transverse process being the nose
  • the pedicle forming the eye
  • the inferior articular facet being the front leg
  • the superior articular facet representing the ear
  • the pars interarticularis (the lamina between the facets) equivalent to the neck.

If a spondylolysis is present, the pars interarticularis will have a defect and look like the Scotty dog has a collar – or doggy decapitation for those with a bloodier imagination!
