The size of a one-dollar coin is equivalent to the cover of our adult thumbs, in the provincial orthopedics director Xu Jie here as long as such a large incision can be used to complete the channel under the lumbar spondylolisthesis, lumbar disc herniation surgical treatment. Traditional open surgery for lumbar disc herniation and lumbar spondylolisthesis requires an incision of about 10 centimeters in the lumbar back, which requires the stripping of paravertebral muscles, making the surgery traumatic, destroying the normal structure of the spine, slowing the recovery, and making it easy to leave behind chronic low back pain and other complications after the surgery. Minimally invasive spinal channel surgery is the use of the current international advanced spinal expandable channel system, only in the skin to make a 1~2cm incision, can be through the minimally invasive expandable channel for disc resection, decompression, fusion, restoration, internal fixation. This minimally invasive procedure is accessed from the paraspinal muscle space of the spine, maximizing the protection of the paraspinal muscles, with less intraoperative bleeding, less damage to the normal spinal structure, and quicker postoperative recovery, which can significantly reduce the occurrence of postoperative low back pain. The picture shows the operation process of lumbar spine channel installation with exposed vision The picture shows Director Xu Jie performing decompression, repositioning, bone grafting, and endoprosthesis under the channel microscope. Minimally invasive spine surgery can treat lumbar disc herniation, recurrent lumbar disc herniation, lumbar spondylolisthesis, lumbar spine instability and so on. Case sharing: Case 1: Lumbar spondylolisthesis treatment The patient with lumbar spondylolisthesis was very happy with the post-operative outpatient review, the pain was solved, and life was free! Case 2: Internal fixation treatment for lumbar disc herniation. Lumbar 4/5 disc herniation, channel microscopy treatment and review of films, intraoperative routine electrophysiologic nerve monitoring. Case 3: Simple nucleus pulposus removal. Microscopic treatment of simple lumbar herniation with a much smaller incision!!!! The size is about index finger size 1.8cm. The patient’s postoperative review photos 1.5 months after surgery, the scar has almost disappeared. Professor Xu Jie introduced the advantages of channel microscopic surgery: channel minimally invasive spine surgery compared with traditional spine surgery, its advantage lies in the process of surgical exposure without extensive soft tissue stripping, but the use of a series of step-by-step dilatation of the pipeline through the lumbar paraspinal muscular space to expand, so as to establish a working channel, and in the working channel for microscopic surgical exposure, decompression, propping, fusion and internal fixation surgery,. Surgical operations are more delicate and safer. This channel surgery system has the advantages of small incision, less bleeding, less pain and faster recovery.
