Lumbar disc herniation, lumbar spinal stenosis, and lumbar spondylolisthesis are very common diseases in clinical practice. The pain of the disease torments the patients all the time, but the large wound, soft tissue damage, intraoperative bleeding, chronic back pain, lumbar weakness, soreness and other symptoms have been troubling the surgeons after the surgery. However, the minimally invasive access (mis-tlif:) technology started to completely solve the problems that have been troubling doctors. Minimally invasive access technology not only obtains the same treatment effect as open surgery, but also gets down to the ground 2-3 days after surgery, which is significantly longer than traditional surgery. Moreover, intraoperative bleeding is significantly reduced and blood transfusion is reduced. The drainage is low and the surgical incision is small, 1.5-3 cm long. The important thing is that less bone is removed during the operation, and there is basically no damage to the muscle tissue, which reduces the symptoms of postoperative patients such as lumbar soreness and weakness, and plays a great role in early recovery. Minimally invasive access treatment scope: lumbar disc herniation, lumbar spinal stenosis, lumbar spine 1-2 degree slippage, thoracolumbar spine fracture.
