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 ...
Retrolistheses are most easily diagnosed on lateral x-ray views of the spine. Views where care has been taken to expose for a true lateral view without any rotation offer the best diagnostic quality. Retrolistheses are found most prominently in the cervical spine and lumbar region but can also be seen in the thoracic area.
Spinal stenosis began to be recognized as an impairing condition in the 1950s and 1970s. Individuals who experience back pain and other symptoms are likely to have bigger spinal canals than those who are asymptomatic. [45] A normal-sized lumbar canal is rarely encountered in persons with either disc disease or those requiring a laminectomy. [31]
Obliques 20 degrees from lateral may be ordered to better visualize the zygapophysial joint. Lumbar Spine - AP and Lateral +/- L5/S1 view in the UK, with obliques and Flexion and Extension requests being rare. [15] In the US, basic projections include an AP, two Obliques, a Lateral, and a Lateral L5-S1 spot to better visualize the L5-S1 interspace.
In human anatomy, the five vertebrae are between the rib cage and the pelvis.They are the largest segments of the vertebral column and are characterized by the absence of the foramen transversarium within the transverse process (since it is only found in the cervical region) and by the absence of facets on the sides of the body (as found only in the thoracic region).
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.
Inspect for: normal cervical and lumbar lordosis and normal thoracic kyphosis. Whilst standing beside the patient place your index finger on one of the lumbar vertebral spinous processes, and your middle finger on the next one down and ask the patient to bend over and touch their toes, keeping their legs straight.
