Lumbar disc herniation is a common clinical condition. The intervertebral disc is a very useful organ in the human body, like the shock absorption system of a car, it is the shock absorption system of the human spine. From its structure, it looks like a “pie” with a “skin” (annulus fibrosus) on the outside and a “filling” (nucleus pulposus) in the middle, and the so-called disc herniation is the pie’s If the skin is broken, the filling inside will leak out, and this leakage does not matter, it will squeeze the nerve tissue in the back and cause leg pain. In some severe cases, the herniation is so large that it may even cause urinary and fecal dysfunction or muscle paralysis. Conventional surgery involves making an incision at the back of the spine, peeling away the muscles on both sides, and biting off some of the bone before the herniated disc can be seen. However, such an operation is very disruptive to the posterior aspect of the patient’s spine and results in a long postoperative recovery time, as well as a high overall cost of hospitalization due to the use of general anesthesia. As a result, many patients who have a herniated disc and have severe symptoms, but have greater concerns, seek medical help everywhere and delay their condition. Not only are they worried about the risk of surgery, but also the cost of surgery, and the time and energy of their family members who are delayed because the surgery requires care and bedside companionship. Intervertebral foraminoscopy is a new and effective method of treating herniated discs that has been developed in recent years. It can be done under local anesthesia, and the results are positive, and the cost of hospitalization is greatly reduced (1/3 of conventional hospitalization), and the risk of surgery is also greatly reduced. Generally speaking, you can go down to the floor on the second day after the operation and be discharged on the third day, without any special accompanying or nursing care from your family during the hospitalization.
