G54.1: Lumbosacral plexus disorders

The network of nerves in the area between your lumbar spine and your pelvis is damaged.

The spine consists of several sections. The cervical spine begins below the head. The cervical spine is very mobile. Below that is the thoracic spine. The ribs are attached to the thoracic spine. Below the thoracic spine is the lumbar spine. The lumbar spine is also very mobile and it bears a large part of the body’s weight. After the lumbar spine, the sacrum and coccyx join.

The spine contains the spinal cord. The spinal cord is made up of nerve fibers. To the side of the spine, the nerve fibers emerge from the spinal cord and form nerves. Nerves are a sort of wiring in the body. Nerves conduct information. The nerves use electrical impulses to do this. Nerves are important, for instance, in enabling you to sense contacts and temperatures, and to move your muscles.

To the side of the lumbar spine and at the sacrum, nerves emerge to serve the leg and the buttocks. Together, the nerves in the area between your lumbar spine and your pelvis form a network. When the neuroplexus is damaged, one may have various symptoms. You may no longer be able to move certain muscles in your leg or buttocks properly, for example. The skin in your leg or buttocks may also feel tingly or numb. You may also feel soreness in those areas.
