Risotomy (or destruction of the facet nerve, or radiculotomy) is an operative intervention, the essence of which is to cut the roots of the spinal cord at the level of its departure from the spinal cord.
Destruction of the facet nerve (rhizotomy) is a minimally invasive surgical intervention, consisting in inactivation of the pain receptors of the intervertebral joints (i.e., the facet joints). This procedure is most effective in the presence of the so-called facet syndrome, i.e. pain associated with the overload of these joints - this is usually a pain, which is greatly enhanced by extension in the lumbar spine. A special blockade of these nerves is preliminarily carried out, and under considerable relief the destruction of the facet nerve is carried out using a radio-frequency probe. The procedure is performed under local anesthesia.
The operation is of two types:
· Front - intersecting the motor nerve roots
· Rear - sensitive nerve roots intersect
· Indications for rhizotomy
· Indications for the conduct of rhizotomy are the following conditions in the patient:
· Spinal trauma
· Gunshot wounds to the spine
· Complications after encephalitis
· Severe pain syndrome (not drug-resistant) with radiculitis
· Neuralgia of the spinal nerve
· Little's disease (a form of cerebral palsy)
· Spastic paralysis
· Spasmodic torticollis
· Malignant and benign tumors of the spinal cord and spine with severe pain syndrome
