Minimally invasive surgery for lumbar disc herniation is currently the most popular minimally invasive surgical treatment with intervertebral foraminoscopy. Under local anesthetic, a 7mm surgical incision is made to reach the location of the herniated disc, and the herniated disc is removed with the aid of a tube and foraminoscope to achieve nerve root decompression. The operation takes about 2 hours and the bleeding is about 20 ml. The patient is awake during the operation and can answer and communicate with the surgeon. The patient’s lower extremity symptoms are relieved immediately after the operation, and the postoperative bed rest time and recovery time are short. Studies have shown that the recurrence rate of intervertebral foraminal surgery is low, and the efficiency rate is above 95%. Therefore, foraminoscopic surgery is recommended for patients with simple disc herniation.
