. The spine or spine is one of the most important parts of your body. It provides the primary support that allows you to stand. Bend and twist. 33 individual bones interlock with each other to form the spinal column. The vertebrae. They are numbered and divided into regions c1 to c7 the cervical vertebrae form your neck they support your head and neck and allow you to nod and shake your head t1 to t12 thoracic which are the 12 vertebrae that are joined by ribs to form your rib cage l1 to l5

lumbar

Your five sturdy lumbar vertebrae support most of the weight of your upper body and provide a stable center of gravity when you move.

Five vertebrae from the sacrum and four from the coccyx are fused, forming the posterior wall of the pelvis between each of the mobile vertebrae. where the vertebrae are located the intervertebral disc the intervertebral discs consist of a thick outer layer with a crisscrossing fibrous structure a ring surrounding the soft, gel-like center the central discs function as shock-absorbing springs the ring brings the vertebral bodies together against elastic resistance of the gel-filled nucleus when the nucleus is bent it acts as a ball bearing allowing the vertebral bodies to rotate on the incompressible gel each disc works in conjunction with two facet joints forming a spinal motion segment the biomechanical function of each pair of facet joints en To guide and limit the motion of the spinal motion segment, the joint surfaces are covered with cartilage that helps each joint move smoothly directly behind the discs.

The ring-shaped vertebral bodies create a vertical tunnel called the spinal canal or neural canal. Spinal cord. and the spinal nerves pass through the spinal canal which protects them from injury the spinal cord is the main column of nervous tissue that is connected to the brain and serves as an information highway between the brain and the body the nerves of the spinal cord are They branch into pairs of nerve roots that travel through the small openings between the vertebrae and enter the vertebral foramen, and as a result of aging or trauma, the intervertebral disc can become damaged or degenerate.

Loss of disc height can cause a bulging disc, putting pressure on the nerves exiting the spine. Degeneration and overload of the facet joints can cause arthritis overgrowth. This resulting loss of space in the foramen can cause compression or pinching of the nerve roots as they exit the spine. This condition is called lateral stenosis. Spondylolisthesis is a common lumbar spine problem when the disc is unstable. and allows the upper vertebral body to slide forward. Lumbar disc disease can cause severe pain in the back and legs and sporadic tingling or weakness in the knees. Treatment of disc diseases aims to restore the height of a disc and stop movement to relieve pain. tlif is defined as

This approach requires a small incision in the back and can be performed as a minimally invasive procedure through a one-inch portal. An initial supplemental posterior fixation is used to significantly improve the stability of the motion segment. The traditional tlif approach. requires the facet joint to be removed to access the spine, this allows the implant to be placed without manipulating the spinal cord. The surgeon can then remove the nucleus of the diseased disc to prepare the vertebral bodies for fusion. A bone graft is first placed into the anterior disc space. After the disc is prepared, a biocompatible polymer implant is filled with bone graft material and placed in the disc space.
Additional bone graft may be placed around the implant to increase the fusion surface. This procedure is typically accompanied by posterior fixation with pedicle screws or facet screws. The implant maintains the spacing of the vertebrae while the fusion is performed. After the fusion is complete and a solid bone mass is formed, the two vertebrae are joined in the center of the spine. Atlantic column less invasive better results
