Lumbar disc herniation and lumbar spondylolisthesis are two common lumbar spine diseases that bring a lot of pain to people’s lives. Traditional open posterior lumbar spine internal fixation surgery has such disadvantages as high infection rate, heavy bleeding, large damage to the paravertebral muscles, hospitalization time and long time in bed. Our department adopts minimally invasive expansion channel intervertebral fusion percutaneous pedicle screw internal fixation for lumbar spondylolisthesis and lumbar disc herniation, which allows patients to get out of bed early and avoid extensive stripping of paravertebral muscles, ligaments and fascia and muscle ischemic necrosis and fibrosis caused by prolonged muscle pulling. It prevents the resultant long-term postoperative persistent pain and stiffness in the low back. It avoids the medically induced injuries associated with posterior lumbar spine surgery. Lumbar fusion is currently the mainstay of treatment for lumbar degenerative diseases, lumbar instability and discogenic disorders. Transforaminal lumbar interbody fusion (TLIF) is a new type of lumbar fusion developed in recent years, and with the progress of minimally invasive spinal surgery (MISS), minimally invasive TLIF technology has also been With the advancement of minimally invasive spinal surgery (MISS), the minimally invasive TLIF technique has also developed rapidly and has further advantages over traditional open TLIF. The wound is about 1 cm, and you can be on the floor the day after surgery, and you can be discharged from the hospital in 1 week and resume work and life early.
