M96.3: Postlaminectomy kyphosis

If you look at the spine from the side, you can see that it usually is not quite straight. The spine is alternately curving inwards and outwards. The cervical spine and the lumbar spine curve forwards. The thoracic spine and sacrum curve outwards.

The spine can be curved backwards too much in one or more sections.

In the past you had surgery that involved the removal of one or more vertebral arches. 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. The spine may be less stable after this type of operation. The spine can then curve backwards too much. If the spine is too curved, it may cause back pain.
