For recurrent disc herniation, open surgery can easily lead to nerve damage due to adhesions in the spinal canal, scar tissue formation and anatomical ambiguity. However, this problem can be solved by minimally invasive lateral foraminoscopic surgery, which avoids going the old way and can be safely performed under local anesthesia using an incision of only about 0.7 cm, and can completely solve the recurrence problem. Below are pictures and information of a complex recurrent lumbar disc herniation done by Director Wang Yun’s team. Typical case: The patient, male, 42 years old, had an open nucleus pulposus decompression of the L45 disc 20 years ago, and was reviewed again this time. The site of the herniated disc was reviewed as it was together, causing radiating pain and numbness in the left lower extremity. This time, Director Wang Yun performed a minimally invasive lateral foraminoscopic surgery under local anesthesia, and the operation lasted only one hour, with satisfactory postoperative recovery.
