M96.1: Postlaminectomy syndrome, not elsewhere classified You are in pain once more after an operation on your spine. The spine is made up of the individual vertebrae. Between every 2 vertebrae there is a vertebral disc. Most vertebrae consist of a vertebral body and a vertebral arch. The vertebral body bears the weight of the body. The vertebral arches lie on top of one another to form the spinal canal. The spinal cord lies in the vertebral canal. Intervertebral discs consist of cartilage and connective tissue. Intervertebral discs connect neighboring vertebrae to one another and absorb pressure and shocks. One or more of your vertebral arches were removed in the course of an operation. This is done for slipped discs, for example, or when the spinal cord does not have enough room in the vertebral canal, which often results in pain. For different reasons, the pain can reoccur after the operation. Nerves may be damaged. The vertebrae form the vertebral canal on the rear of the spinal column. The spinal cord runs in the vertebral canal. Nerve fibers run from the brain into the body via the spinal cord and form nerves there. Every nerve is responsible for a particular part of the skin and for certain muscles. These nerves are important for instance in enabling you to feel and move the muscles. Or a scar or other tissue may be pressing on the nerves, for example.
