Lumbar spine

Lumbar Spine

The Lumbar spine is the lower part of the spine, located between the thoracic spine and the sacral spine. It consists of five vertebrae, known as L1 - L5. The lumbar spine carries the most body weight and is more susceptible to injury.

Anatomy

The lumbar spine is made up of five vertebrae, each separated by a disc. The vertebrae are numbered L1 to L5, from top to bottom. The lumbar spine connects the thoracic spine and the sacral spine. The vertebrae are the largest segments of the vertebral column and are characterized by the absence of the foramen transversarium within the transverse process and by the absence of facets on the sides of the body.

Function

The main function of the lumbar spine is to bear the weight of the body. The five vertebrae of the lumbar spine are the largest and strongest of the spinal column. They are designed to withstand significant amounts of stress.

Conditions

There are several conditions that can affect the lumbar spine, including lumbar disc disease, lumbar stenosis, and spondylolisthesis. These conditions can cause pain, numbness, and other symptoms.

Treatment

Treatment for conditions affecting the lumbar spine can range from conservative measures such as physical therapy and medication, to more invasive procedures such as surgery. The specific treatment will depend on the nature and severity of the condition.
