Abstract: In recent years, minimally invasive spinal surgery technology has developed rapidly, but at the same time, there are many controversies. The third annual meeting of the Minimally Invasive Spinal Surgery Working Group of the Chinese Medical Education Association focused on seven hot issues: the selection of percutaneous vertebroplasty and kyphoplasty and the amount of bone cement perfusion; the selection of percutaneous transforaminal endoscopic and microendoscopic discectomy for sequestered disc herniation; the minimally invasive surgical strategy for degenerative scoliosis; minimally invasive options for lumbar spinal stenosis; the choice of microscopy and endoscopy for cervical disc herniation; minimally invasive strategies for degenerative lumbar spondylolisthesis; and the choice of endoscopic and open surgery for thoracic spinal stenosis. The characteristics, advantages and limitations of various minimally invasive techniques have fully discussed, and some consensus has been reached, which is beneficial to development and application of various minimally invasive techniques.
