Lumbar

Lumbar refers to the area of the spine specifically the five vertebrae in the lower part of the spine between the ribs and the pelvis. The lumbar region is sometimes referred to as the lower spine, or as an area of the back in its proximity.

The lumbar region is designed for both power and flexibility - lifting, twisting, and bending. The lower back bears the weight of the upper body and provides mobility for everyday movements such as bending and twisting.

Anatomy

The lumbar spine (lower back) consists of five vertebrae labeled L1 through L5. These lumbar vertebrae contain spinal cord tissue and nerves which control communication between the brain and the legs.

Lumbar Vertebrae

The lumbar vertebrae are the some of the largest and heaviest vertebrae in the spine, and are designed to carry most of the body’s weight. Each lumbar spinal level is composed of a disc in the front and paired joints in the back that work together to allow movement and provide stability.

Lumbar Discs

The lumbar discs are designed to absorb shock and keep the spine flexible. They are the soft, compressible discs that separate the interlocking bones (vertebrae) that make up the spine.

Conditions

There are many conditions that can affect the lumbar region, including Lumbar disc disease, Lumbar spinal stenosis, and Lumbar spondylosis. These conditions can cause pain, numbness, or even paralysis in the lower body.

Treatment

Treatment for lumbar conditions can range from conservative treatments such as physical therapy and medication, to more invasive treatments such as surgery. The type of treatment will depend on the severity of the condition and the patient's overall health.
