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 Today, myelography has largely been replaced by the use of MRI scans , although the technique is still sometimes used under certain circumstances – though now usually in conjunction with CT ...
Lumbar hyperlordosis is excessive extension of the lumbar region, and is commonly called hollow back or saddle back (after a similar condition that affects some horses). Sway back is a different condition with a different cause, that at a glance can mimic the outward appearance of lumbar hyperlordosis.

[ 4 ] Rarely, large anterior cervical spine osteophytes may affect the esophagus or the larynx and cause pain , difficulty swallowing [ 5 ] [ 6 ] or even dyspnea . [ 7 ]
Projectional radiography relies on the characteristics of X-ray radiation (quantity and quality of the beam) and knowledge of how it interacts with human tissue to create diagnostic images. X-rays are a form of ionizing radiation, meaning it has sufficient energy to potentially remove electrons from an atom, thus giving it a charge and making ...
A diagnosis of kyphosis is generally made through observation and measurement. Idiopathic causes, such as vertebral wedging or other abnormalities, can be confirmed through X-ray. Osteoporosis, a potential cause of kyphosis, can be confirmed with a bone density scan. Postural thoracic kyphosis can often be treated with posture reeducation and ...
Herniated lumbar disc. Lumbar disc herniations occur in the back, most often between the fourth and fifth lumbar vertebral bodies or between the fifth and the sacrum. Here, symptoms can be felt in the lower back, buttocks, thigh, anal/genital region (via the perineal nerve), and may radiate into the foot and/or toe.
