Minimally invasive lumbar protrusion surgery should pay attention to the pre-surgical examination, intra-surgical operation and post-surgical recovery. 1. Pre-operative examination: Before performing minimally invasive lumbar surgery, the doctor needs to conduct a comprehensive examination of the patient. The severity of the patient’s condition and the patient’s physical condition should be clarified to ensure that the patient can withstand the minimally invasive surgery. 2. Operation during surgery: During the operation, the doctor should minimize the damage to the lumbar spinal cord and pay special attention to carefully stopping the bleeding. Even though the surgery is minimally invasive, it can cause some physical damage to the patient. 3. Post-operative recovery: In the early days after the surgery, attention should be paid to wearing lumbar protective gear, avoiding excessive activities, and the wound should be treated with regular dressing changes. After the lumbar condition is stabilized, some lumbar exercises can be carried out appropriately to enhance the muscle strength of the lumbar region and improve the stability of the lumbar spine. When the patient has a herniated lumbar disc, it is necessary to carry out surgical treatment in time, paying attention to the above precautions.
