A break in the neck of the dog, or a dog collar, corresponds to a fracture in the region of the pars interarticularis, which is specific for spondylolysis. It is important to recognize as it is a cause of low back pain. A. Normal The doctor traces around the vertebral body and bony ring on the X-ray film. The outline normally forms an image that looks like a small dog. When a crack is present, however, the dog will appear to have a collar around its neck. This is referred to as the Scotty dog sign. It confirms a diagnosis of spondylolysis Spondylolysis is believed to be caused by repeated microtrauma, resulting in a stress fracture of the pars interarticularis. A dysplastic pars is usually present. Genetics are also believed to be a factor

Spondylolysis and Spondylolisthesi

Spondylolysis is a stress fracture through the pars interarticularis of the lumbar vertebrae. The pars interarticularis is a thin bone segment joining two vertebrae. It is the most likely area to be affected by repetitive stress. This condition is fairly common and is found in one out of every 20 people Spondylolysis. In spondylolysis, a crack or stress fracture develops through the pars interarticularis, which is a small, thin portion of the vertebra that connects the upper and lower facet joints.. Most commonly, this fracture occurs in the fifth vertebra of the lumbar (lower) spine, although it sometimes occurs in the fourth lumbar vertebra Definitions. Spondylolysis. Vertebra l defect at pars interarticularis (one or two defects) When two, bilateral Pars Defects occur, Spondylolisthesis ( Vertebra l slippage) occurs. III. Epidemiology. Uncommon cause of back pain in general population, non-athletes. Incidence in age <40 years old: 6% This outline is referred to as the Scotty dog sign, and the pars defect may be referred to as a Scotty dog fracture. The presence of this collar or dark line on the outline of the Scotty dog sign confirms a spondylolysis diagnosis. In some cases, spinal X-rays are unable to detect smaller defects or stress fractures within the spinal bones

Spondylolysis is a defect in the pars interarticularis of the vertebral arch, most often in the fifth lumbar vertebrae. It is the most common cause of chronic low back pain in adolescents, and is easily recognized on radiograph by the Scotty-dog sign The red outlined anatomy is commonly known as Scotty Dog. p 273, Williams and Wilkins) The etiology of spondylolysis is overwhelmingly congenital, although sporadic reports of traumatic lumbar spondylolysis appear in the literature. CT imaging will usually identify the defects as characteristically acute or otherwise The defect in isthmic spondylolysis is visualised as a lucency in the region of the pars interarticularis. The lesion is commonly described as having the appearance of a collar or a broken neck on the Scotty dog seen in lateral oblique radiographs (fig 1D) If a collar is present on the Scotty Dog, spondylolysis is present. Various measurements from the lateral films can aid as prognostic factors for slippage progression or determining a patient׳s suitability for treatment. The degree of slippage according to Meyerding׳s classification can be assessed. The slip angle is the degree of.

The classic X-ray finding of a spondylolysis is known as the scotty dog sign. This sign describes the manner in which the spondylolysis defect can look (to someone with a very healthy imagination) like the collar on a scotty dog on the oblique views of the limbo-sacral junction. While the gap can be seen on plain X-ray, often a CT or an. Spondylosis is a type of osteoarthritis affecting the spine; it is primarily a disorder of the intervertebral joints. Spondylolysis (this page) is, The diagram of the scotty dog outline was an interesting way to describe the pars defect. There is a good amount of pictures and diagrams. There was a sufficient amount of information Spondylolysis is a break in the pars interarticularis. If the defect permits displacement of one vertebra on another, it is termed spondylolisthesis (Fig. 72.22 ). Spondylolysis, with or without spondylolisthesis, is a common structural abnormality; however, only 5% of patients with the condition become symptomatic Lumbar Spondylolysis is the unilateral or bilateral defect of the pars interarticularis of the vertebral arch, which can be accompanied by vertebral displacement in the lumbar region [1]. As a result this can be characterised by the collapse or narrowing of the disc space [2]. Spondylolysis derives from the Greek words Spondylos (Vertebra) and lysis (Defect) [3]

Spondylolysis bilaterally in adults is a condition that occurs when a crack is formed in the bony ring that is located in the back of an adult's spinal column. The most common place for this to occur is in the lumbar region or the lower back. When spondylolysis bilaterally in adults occurs, the bone responsible for protecting the spinal cord sustains a fracture as a result of either excessive. Standard X-rays are performed for many reasons, including diagnosing tumors or bone injuries. X-rays are made by using external radiation to produce images of the body, its organs, and other internal structures for diagnostic purposes. X-rays pass through body structures onto specially-treated plates (similar to camera film) and a negative.

In spondylolysis, a fracture, or crack, in the thin part of a vertebra can result in vertebrae slipping backward, forward, or over a bone below.
