The first orthopedic osteotomy techniques for spinal deformities (SRS 2-6 level osteotomy) including VCR osteotomy for various complex and severe spinal deformities were carried out in Ningxia region ① the first case of VCR osteotomy for severe idiopathic lateral kyphosis; Gao Zhaohui, Department of Orthopedic Spine, General Hospital of Ningxia Medical University ② the first case of Marfan VCR osteotomy for severe kyphosis in Marfan syndrome; ③The first case of VCR osteotomy for very severe congenital kyphosis 2. Multi-segment VCD osteotomy orthopedic correction 3. First in Ningxia to carry out VCM integral de-rotation technique for adolescent idiopathic scoliosis 4. First in Ningxia to carry out growth valve technique for various congenital and idiopathic scoliosis 5. First in Ningxia to use 3D printing technology guided surgery for various complex spinal deformities 6. Minimally invasive MINI-OPEN TLIF technique for lumbar degenerative diseases (lumbar intervertebral herniation, spinal stenosis, spinal slippage, spinal instability, etc.) under the Wiltse approach 2. osteotomy orthopedic fusion fixation of severe degenerative lateral kyphosis deformity (including PSO, Ponte, VCD) Phase I posterior total spondylolisthesis (EN BLOC) for spinal tumors (first in Ningxia) Phase I posterior lesion removal and stability reconstruction for thoracolumbar and lumbosacral spinal tuberculosis (first in Ningxia) Phase I anterior split sternal approach for cervicothoracic tuberculosis and bone graft stability reconstruction (first in Ningxia) Phase IV upper cervical spine (atlantoaxial spine) disorders 2. Atlantoaxial instability and dislocation of the first phase of posterior arch nail fusion (the first case in Ning Medical General Hospital) 3.
