Intervertebral foraminoscopy is currently considered the most minimally invasive surgical technique. Its significant advantages are: the use of local anesthesia, lateral access from the lumbar region, television endoscopic surveillance, and a small incision of only 6 mm; in detail, local anesthesia makes it possible for many patients with geriatric disease who would otherwise be inoperable to undergo surgery; moreover, the patient will respond when the nerve is encountered during surgery, which greatly reduces the risk of surgery; lateral puncture into the intervertebral foramen is considered the most The lateral puncture into the intervertebral foramen, which is considered the most scientific approach, reduces interference with the spinal canal (i.e., reduces interference with other nerves); the operation is performed under endoscopic surveillance (close to direct vision), which makes the operation safe and effective; the damage to the body during the operation is minimal, and the patient can walk on the floor after the operation. Generally, the patient is discharged from the hospital on the same day after surgery (day surgery). 1, not that minimally invasive is good, open standard surgery is not good, according to the specific condition, choose an effective surgical method, the most critical tube and effective, rather than minimally invasive. It is good to have efficacy, and to pursue minimally invasive on this basis. Therefore, do not figure the name, but be pragmatic. 2, without surgery, is the most minimally invasive. Through exercise, posture improvement, with a conservative and harmless method, is the most most minimally invasive.
