Lumbar disc herniation, lumbar spinal stenosis, degenerative lumbar spondylolisthesis, degenerative scoliosis of the lumbar spine, osteoporotic fracture of the thoracolumbar spine, severe lower back pain due to intervertebral disc origin or small joint synostosis origin, and other degenerative disorders of the thoracolumbar spine. Minimally invasive spine surgery is now mature. Specific techniques include: 1, spinal endoscopy (noted not discoscopy technology, but intervertebral foramenoscopy technology / percutaneous cervical endoscopy technology, PELD): including interlaminar approach and intervertebral foraminal approach, through which nucleus pulposus removal; intervertebral foramen enlargement plasty, intervertebral fusion, and so on. 2.Cavity assisted technology: including Mis-TLIF, Mis-XLIF, Mis-ALIF, Mis-DLIF; 3.Transpercutaneous technology: including PKP technology to treat osteoporotic compression fracture; percutaneous pedicle technology to treat fracture or immobilization of vertebrae, etc. 4, Percutaneous spinal endoscopic posterior medial branch dissection of spinal nerve: to treat severe low back pain and neck pain caused by osteoarthritis of the small joint synapse; if conservative information is ineffective, minimally invasive percutaneous spinal endoscopic posterior medial branch dissection of spinal nerve can be used.
