PRT therapy is directed at the treatment of radicular syndromes caused by compression of nerve roots in the spinal canal as a result of various pathological processes. Such conditions may include foraminal stenosis (the narrowing of the spinal canal), postoperative fibrosis in the epidural space, and other conditions. PRT is one of the treatment possibilities in which anti-inflammatory drugs can be injected together with a local anaesthetic close to the nerve root.
Patients who often benefit from PRT are those with herniated intervertebral discs as diagnosed on CT or MRI imaging. If the pain of a patient diagnosed with radicular syndrome persists for more than three months, despite medical treatment and physiotherapy, PRT is a good indicated option. Its aim is to relieve pain and the inflammatory symptoms at the nerve root area.
It is important to note that PRT may not be indicated for every condition which causes spinal root compression. Examples of contraindications are free fragment, malignant disease, severe acute or chronic inflammatory disorders, coagulation, and others.
