S34: Injury of nerves and lumbar spinal cord at abdomen, lower back and pelvis level
S34.4: Injury of lumbosacral plexus
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.
The lumbar spine consists of 5 vertebrae and it is located between the thoracic spine and the pelvis. Beneath the lumbar spine is the sacrum. The sacrum consists of fused vertebrae and it is connected to the pelvis.
To the side of the lumbar spine and at the sacrum, nerves emerge to serve the lower half of the body. Together, the nerves in the area between your lumbar spine and your pelvis form a network. When the network of nerves between the lumbar spine and the pelvis is damaged, there can be a variety of symptoms. You may no longer be able to move certain muscles in your leg or buttocks properly, for example. You may also have less sensation in some parts of your behind or your leg.
