A spondylolisthesis, colloquially called a spondylolisthesis is an instability of the spine, the ventral part of the upper portion of the spine with Spondylolisthesis of the section below and in front of the slipped slipping. In the opposite case we speak of a retrolisthesis.
Although at first spondylolisthesis often have few complaints, the sliding of the vertebral body can lead to long term, that one or more nerves in the spinal canal trapped and stretched. This can cause nerve damage and loss of function of a nerve lead. There may be paralysis, which concern both the legs and the function of bladder and bowel. At the same time wear out the disc and facet joint in the corresponding segment excessively, which can sometimes cause severe pain.
This is from the same investigation as the one shown above, but to a later date. It is clear that is caused by the high grade spondylolisthesis Foramenstenose. The nerve root of 5th Ledenwirbelkörpers is thus strongly compressed (see yellow circle), the resultant changes are not to eliminate pain and make a conservative surgery.
Although spondylolisthesis often causes only a few symptoms at first, the gliding of the vertebral body can in the long run cause one or more nerves to become trapped and stretched in the spinal canal.
This can cause nerve damage and lead to a functional failure of a nerve.
There may be paralysis affecting both the legs and bladder and bowel function. At the same time, the intervertebral disc and the vertebral joint in the corresponding segment wear excessively, which can sometimes cause severe pain.
This picture shows spondylolisthesis in the lateral lumbar spine in segment L5 / S1. The vertebrae are offset by 18 mm. The disc is severely deformed, the disc space L5 / S1 greatly reduced in height. The spinal canal, however, is free.
This image comes from the same study as the one shown above, but at a later date. It becomes clear that the vertebral gliding has resulted in a severe foramen stenosis. The nerve root of the 5th Ledenwirbelkörpers is thereby greatly compressed (see yellow circle), the resulting pain can not be removed conservatively and require surgery.
