Structure and Function of the Lumbar Spine


Dr. Luis Lombardi performs non-traumatic spine surgery through his private practice in Los Angeles, California. Dr. Luis Lombardi draws on experience in treating a variety of back pain conditions, including those involving the lumbar spine.

Of the 26 individual vertebrae that combine to form the spinal column, the lowest five make up the region known as the lumbar spine. The vertebrae in this area are the largest in the spine, as they bear the majority of weight placed on the spine by the trunk and head.

Each vertebra of the lumbar spine consists of a vertebral body at the front and a series of attached posterior elements. The body and posterior elements surround a large gap, known as the spinal canal, through which a sac with nerves called cauda equina passes. A series of spinal nerves branch out from the spinal canal between each pair of vertebrae, where there is also a cushioning disc to absorb shock and a pair of facet joints to facilitate movement.

While the facet joints between the vertebrae link one to the other, a network of ligaments connect multiple vertebrae and let the spine work as a whole. Tendons connect the bones to the back muscles, which in the lumbar spine include the multifidus and spinalis. If a patient is experiencing pain in the lumbar spine, the non-traumatic procedures that Dr. Lombardi performs can provide therapeutic intervention without harm to these essential structures.
