A discectomy (also called open discectomy, if done through a 1/2 inch or larger skin opening) is the surgical removal of abnormal disc material that presses on a nerve root or the spinal cord. The procedure involves removing a portion of an intervertebral disc, which causes pain, weakness or numbness by stressing the spinal cord or radiating ...
The surgical procedure is typically done in two stages, but it is possible to conduct the surgery in one stage. The first stage is the discontinuation of the waste functions by performing a colostomy and ileal conduit in the upper abdominal quadrants. The second stage is the amputation at the lumbar spine.

Lumbar spinal stenosis (LSS) is a medical condition in which the spinal canal narrows and compresses the nerves and blood vessels at the level of the lumbar vertebrae. Spinal stenosis may also affect the cervical or thoracic region, in which case it is known as cervical spinal stenosis or thoracic spinal stenosis.
After age 50 or 60, osteoarthritic degeneration (spondylosis) or spinal stenosis are more likely causes of low back pain or leg pain. 4.8% of males and 2.5% of females older than 35 experience sciatica during their lifetime. Of all individuals, 60% to 80% experience back pain during their lifetime. In 14%, pain lasts more than two weeks.
Back surgery can relieve pressure on the spine, but it is not a cure-all for spinal stenosis. There may be considerable pain immediately after the operation, and pain may persist on a longer-term basis. For some people, recovery can take weeks or months and may require long-term occupational and physical therapy.
Low back pain is the greatest contributor to lost productivity, absenteeism, disability and early retirement worldwide. [26] Difficulty with low back pain most often begins between 20 and 40 years of age. [1] Women and older people have higher estimated rates of lower back pain and also higher disability estimates.

SDR begins with a 1- to 2-inch incision along the center of the lower back just above the waist. An L1 laminectomy is then performed: a section of the spine's bone, the spinous processes together with a portion of the lamina, are removed, like a drain-cap, to expose the spinal cord and spinal nerves underneath. Ultrasound and an X-ray locate ...
There is also a notable incidence of lumbar spinal fusion patients that present with sacroiliac pain and hypermobility, potentially due to the adjacent lumbar joints being fixed and unable to move. Clinical studies have found up to 75% of post-lumbar fusion patients develop SI joint degeneration within five years of surgery. [14]
