The lumbar spine, also known as the lower back, is made up of five vertebrae (L1-L5) that are located in the lower part of the spine, between the ribcage and the pelvis. The vertebrae are separated by intervertebral discs, which act as shock absorbers and allow the spine to bend and twist. The lumbar spine is supported by a network of muscles, tendons, and ligaments, which help to maintain proper posture and movement.
The spinal cord runs through the center of the vertebral column and is protected by the vertebrae. Nerves branch out from the spinal cord and travel to the rest of the body, carrying messages between the brain and the muscles and organs.
In addition to the vertebrae, the lumbar spine also includes several other structures, such as the facet joints, which allow the vertebrae to move and rotate, and the intervertebral discs, which act as cushions between the vertebrae. The lumbar spine is also surrounded by a group of muscles known as the erector spinae, which help to support and stabilize the spine.
- Muscle strains: A muscle strain is a common injury that occurs when the muscles in the lower back are stretched or torn. This can be caused by lifting a heavy object, twisting or bending awkwardly, or engaging in physical activity that puts a lot of strain on the back muscles.
- Herniated disc: A herniated disc occurs when the soft, spongy material that fills the space between the vertebrae (the intervertebral disc) bulges or ruptures, causing pain and discomfort.
- Spinal stenosis: Spinal stenosis is a condition in which the space around the spinal cord narrows, putting pressure on the nerves and causing pain, numbness, and tingling in the lower back and legs.
- Fractures: Fractures of the lumbar spine can occur due to a fall or a car accident, and can cause pain and discomfort in the lower back.
- Lumbar spondylosis: Lumbar spondylosis is a condition that occurs when the vertebrae in the lower back become degenerated or damaged, causing pain and discomfort.
- Lumbar spondylolisthesis: This condition occurs when one of the vertebrae in the lower back slips out of place, causing pain and discomfort.
A Physio factory lumbar brace will help to provide support and stability in this region and reduce the acute flare-up of pain these cause.
