What is Beheaded Scottish terrier sign is seen in? and explain in detail?
Ans BIn the oblique view, the "scotty dog" sign can be seen. It is called a scotty dog sign, as the spinous process and lamina connecting the pedicle show the lateral aspect of a Scottish Terrier or "scotty dog." Scotty dog with a collar is seen in Spondylolysis. When the "scotty dog" looks like he has a thick collar or is beheaded the fracture exists suggesting spondylolisthesis.
