There are two methods commonly used in interventional therapy of lumbar disc herniation, the basic principle is the same, that is, under the guidance of B-ultrasound, CT or open magnetic vibration, a fine needle or a lumbar disc endoscope is inserted into the protruding lumbar disc tissue through the patient's prone position through the back skin. One method is to crush the protruding disc tissue and take it out, and the other method is to vaporize the protruding disc tissue with a radio frequency ablation instrument. Other interventional methods include collagenase injection and laser gasification. Their ultimate goal is to eliminate the protruding intervertebral disc tissue and reduce its compression on nerve roots.
Because they all treat the symptoms rather than the root cause, in principle, there is the possibility of postoperative recurrence. However, even if the lumbar disc herniation is treated by orthopedic surgery, it may recur. Relatively speaking, interventional therapy is a minimally invasive operation, and patients have good tolerance and quick recovery, so there are many hospitals at present.
