Scottie dog sign is a radiological sign which refers to the appearance of lumbar spine in oblique view X-ray. [1] In the X-ray, the spine can be visualised as the lateral view of a Scottie dog, [2] with the pedicle as the eye, the transverse process as the nose, the superior articular facet as the ear and the inferior articular facet as the front leg, spinous process as the body.
X-ray image of an Idiopathic scoliosis. The neuromechanics of idiopathic scoliosis is about the changes in the bones, muscles and joints in cases of spinal deformity consisting of a lateral curvature scoliosis and a rotation of the vertebrae within the curve, that is not explained by either congenital vertebral abnormalities, or neuromuscular disorders such as muscular dystrophy.
Preoperative (left) and postoperative (right) X-ray of a person with thoracic dextroscoliosis and lumbar levoscoliosis: The X-ray is usually projected anteroposterior, such that the right side of the subject is on the right side of the image; i.e., the subject is viewed from the rear (see left image; the right image is seen from the front).
Unless otherwise specified it is generally presumed to refer to angles in the coronal plane, such as projectional radiography in posteroanterior view. In contrast, a sagittal Cobb angle is one measured in the sagittal plane such as on lateral radiographs.
I waited six long months for an appointment to see a specialist about my pain. I saw Robert Inman, MD, a rheumatologist at Toronto Western Hospital, who sent me for X-rays, an MRI, and bloodwork ...
Adolescent idiopathic scoliosis (AIS) is a disorder in which the spine starts abnormally curving sideways between the ages of 10–18 years old. [1] [2] [3] Generally, AIS occurs during the growth spurt associated with adolescence.
Since this is difficult to see on the AP (anterior posterior) x-ray view an oblique x-ray of the lumbar spine can usually identify the spondylolysis. If inconclusive a further CT scan can produce a 3-dimensional images to more clearly show the defect although the exam increases the patients radiation dose by at least an order of magnitude than ...
Anteroposterior (front-back) and lateral (side) images are used to allow the physician to view the spine at multiple angles. [22] Oblique view are no longer recommended. [33] [34] In evaluating for spondylolithesis, plain radiographs provide information on the positioning and structural integrity of the spine. Therefore, if further detail is ...
