Why are all patients so attracted to minimally invasive surgery? The reason is simple, because it solves a big problem with a minimal invasive incision. Cryogenic plasmaplasty (also known as radiofrequency ablation) is a minimally invasive procedure that has obvious clinical advantages. It is mainly reflected in the following aspects: 1. minimal tissue damage; 2. obvious decompression effect; 3. significant pain relief effect; 4. excellent clinical results. Ms. Hou, 35 years old, had persistent pain and soreness and discomfort in her lower back, left hip and thigh for 2 years. The pain worsened whenever she got out of bed, and even worsened when she coughed or sneezed. The patient had been transferred to many hospitals for treatment and had done many treatment measures, including acupuncture, physiotherapy, massage, traction, local closure, sacral canal closure, oral medication and infusion, etc. It can be said that she had tried almost all the treatment methods she had heard of, but the symptoms could not be improved. The hospital took a detailed medical history of Ms. Hou, examined her body, and combined with the results of her lumbar spine MRI, the diagnosis of “discogenic lumbar pain” was clearly made after a department-wide discussion chaired by Director Kuang Zhengda. The surgery plan of cryogenic plasma myeloplasty was formulated. On the first day after surgery, Ms. Hou complained that the pain in her lower back, left hip and thigh was significantly reduced compared with that before surgery. On the second day after surgery, she could move to the ground and complained that the pain disappeared. She was very satisfied with the surgical result and was discharged on the third day after surgery. Minimally invasive surgery includes many kinds of procedures, such as discoscopy, foraminoscopy, percutaneous pedicle nailing and low-temperature plasma myeloplasty. Each minimally invasive procedure has its own indications, and all patients who are capable of minimally invasive surgery should be analyzed on a problem-specific basis to choose the best treatment measures.
