Patients with lumbar disc herniation are very common in daily clinical work, and traditional treatments mostly consist of the application of nutritive nerve medication, reasonable physical therapy or local block can also achieve the purpose of relieving symptoms. In addition, careful and rigorous surgical operation is also very important. In recent years, minimally invasive spinal techniques have developed rapidly, from microscopic minimally invasive surgery, to discoscopic surgery, up to intervertebral foramenoscopic surgery. Traditional open surgeries often require longer operating time and bed rest after surgery, resulting in greater tissue destruction and bleeding, and are associated with higher surgical risks. Minimally invasive techniques can effectively improve these problems. By applying the minimally invasive technology of intervertebral foramenoscopy, our orthopaedic surgery department can make an incision of less than 1 cm; it is less traumatic and causes little damage to the soft tissues and bony structures around the spine; it effectively reduces the operation time and significantly reduces the amount of intra-operative bleeding; local anesthesia is safe and effective, with fewer postoperative complications; it is possible to get down to the ground in 4 hours after the operation, and be discharged from the hospital in 3 days, which reduces hospitalization costs; and the effect of the operation is both positive and remarkable.
