X-ray of Bertolotti's syndrome (in this case, right transverse mega-apophysis of L5 with pseudoarticulation with the sacral ala). Woman 67 years old. Bertolotti's syndrome is a commonly missed cause of back pain which occurs due to lumbosacral transitional vertebrae (LSTV).
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.
Historically the procedure involved the injection of a radiocontrast agent into the cervical or lumbar spine, followed by several X-ray projections. Today, myelography has largely been replaced by the use of MRI scans , although the technique is still sometimes used under certain circumstances – though now usually in conjunction with CT ...
Lumbosacral transitional vertebrae consist of the process of the last lumbar vertebra fusing with the first sacral segment. [1] While only around 10 percent of adults have a spinal abnormality due to genetics, a sixth lumbar vertebra is one of the more common abnormalities. [2] Sacralization of the L5 vertebra is seen at the lower right of the ...
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 ...
Lateral lumbar X-ray of a 34-year-old male. The lumbar curve is more marked in the female than in the male; it begins at the middle of the last thoracic vertebra, and ends at the sacrovertebral angle. It is convex anteriorly, the convexity of the lower three vertebrae being much greater than that of the upper two.
A doctor can diagnose a patient with spondylolisthesis through a physical exam and imaging tests, such as a spinal X-ray, CT scan or MRI. Low-grade spondylolisthesis is the most common type, but ...
X-ray of lumbar hyperlordosis Measurement and diagnosis of lumbar hyperlordosis can be difficult. Obliteration of vertebral end-plate landmarks by interbody fusion may make the traditional measurement of segmental lumbar lordosis more difficult.
