• Spinal nerve compression, inflammation and/or injury
• Sciatica (also called radiculopathy), caused by something pressing on the sciatic nerve that travels through the buttocks and extends down the back of the leg. People with sciatica may feel shock-like or burning low back pain combined with pain through the buttocks and down one leg.
• Spinal stenosis, the narrowing of the spinal column that puts pressure on the spinal cord and nerves
• Spondylolisthesis, which happens when a vertebra of the lower spine slips out of place, pinching the nerves exiting the spinal column
• Herniated or ruptured discs can occur when the intervertebral discs become compressed and bulge outward
• Infections involving the vertebrae, a condition called osteomyelitis; the intervertebral discs, called discitis; or the sacroiliac joints connecting the lower spine to the pelvis, called sacroiliitis
• Cauda equina syndrome occurs when a ruptured disc pushes into the spinal canal and presses on the bundle of lumbar and sacral nerve roots. Permanent neurological damage may result if this syndrome is left untreated.
• Osteoporosis (a progressive decrease in bone density and strength that can lead to painful fractures of the vertebrae)

Artificial disc replacement is an alternative to spinal fusion for treating severely damaged discs. The procedure involves removing the disc and replacing it with a synthetic disc that helps restore height and movement between the vertebrae.

Discectomy and microdiscectomy involve removing a herniated disc through an incision in the back (microdiscectomy uses a much smaller incision in the back and allows for a more rapid recovery). Laminectomy and discectomy are frequently performed together and the combination is one of the more common ways to remove pressure on a nerve root from a herniated disc or bone spur.

Foraminotomy is an operation that “cleans out” or enlarges the bony hole (foramen) where a nerve root exits the spinal canal. Bulging discs or joints thickened with age can narrow the space where the spinal nerve exits and press on the nerve. Small pieces of bone over the nerve are removed through a small slit, allowing the surgeon to cut away the blockage and relieve pressure on the nerve.

Vertebroplasty and kyphoplasty for fractured vertebra are minimally invasive treatments to repair compression fractures of the vertebrae caused by osteoporosis. Vertebroplasty uses three-dimensional imaging to assist in guiding a fine needle through the skin into the vertebral body, the largest part of the vertebrae. A glue-like bone cement is then injected into the vertebral body space, which quickly hardens to stabilize and strengthen the bone and provide pain relief. In kyphoplasty, prior to injecting the bone cement, a special balloon is inserted and gently inflated to restore height to the vertebral structure and reduce spinal deformity.

Spinal laminectomy (also known as spinal decompression) is done when a narrowing of the spinal canal causes pain, numbness, or weakness. During the procedure, the lamina or bony walls of the vertebrae are removed, along with any bone spurs, to relieve pressure on the nerves.

A surgical procedure performed on selected pairs of vertebral lamina to relieve pressure on the SPINAL CORD and which also allows for osteoplastic enlargement of the SPINAL CANAL.

Nucleoplasty, also called plasma disc decompression (PDD), is a type of laser surgery that uses radiofrequency energy to treat people with low back pain associated with mildly herniated discs. Under x-ray guidance, a needle is inserted into the disc. A plasma laser device is then inserted into the needle and the tip is heated to 40-70 degrees Celsius, creating a field that vaporizes the tissue in the disc, reducing its size and relieving pressure on the nerves.

Radiofrequency denervation uses electrical impulses to interrupt nerve conduction (including pain signaling). Using x-ray guidance, a needle is inserted into a target area of nerves and the region is heated, which destroys part of the target nerves and offers temporary pain relief.

Spinal fusion is used to strengthen the spine and prevent painful movements in people with degenerative disc disease or spondylolisthesis (following laminectomy). The spinal disc between two or more vertebrae is removed and the adjacent vertebrae are “fused” by bone grafts and/or metal devices secured by screws. Spinal fusion may result in some loss of flexibility in the spine and requires a long recovery period to allow the bone grafts to grow and fuse the vertebrae together. Spinal fusion has been associated with an acceleration of disc degeneration at adjacent levels of the spine.
