This connection of the vertebrae with each other with the help of special constructions. Distinguish rigid fixation, when the vertebrae are fixed, and dynamic fixation, in which a small but sufficient degree of mobility of the vertebrae is maintained. The most common material of fixatives is titanium. It is an inert metal that does not cause a rejection reaction of tissues and has no magnetic properties.
The most common cause of vertebra fixation is spine trauma. Less often, the vertebrae are fixed with degenerative spinal lesions (eg, spondylolisthesis).
This is an operation in which the surgeon connects two (or more) vertebrae, preventing them from further displacement. In some cases, patients suffering from spinal stenosis, together with spondylodesis, are given a decompression laminectomy whose purpose is to fix those parts of the spine in which vertebral displacement or separation has been recorded. Such fixation can help reduce the intensity of pain, improve the patient's performance and general condition.
Spondylodesis is widely used to treat chronic pain and trauma, which can be caused by the following disorders:
1. Narrowing of the canal of the spinal cord (stenosis)
2. Spondylolisthesis (pathological size of the vertebra)
3. Traumatic spine injury
4. The weakened spine (as a rule, such a problem arises as a result of an infectious lesion or tumor)
5. Scoliosis (pathological curvature of the spine)
