To investigate the clinical effect of double-door laminoplasty combined with C2 dome decompression in treatment of cervical spinal stenosis. ⋯ Double-door laminoplasty combined with C2 dome decompression can directly expand the volume of C2-C3 spinal canal, relieve the compression of spinal cord and nerve root, reduce the damage to the posterior cervical ligament complex as much as possible, maintain the stability of cervical spine sequence, reduce the occurrence of axial symptoms, and the operation is relatively simple, without the need of metal internal fixation.

To compare the degeneration of lumbosacral multifidus muscle in patients with lumbar disc herniation. ⋯ There is degeneration of lumbosacral multifidus muscle on the affected side of patients with unilateral L4,5 intervertebral disc herniation, featuring multifidus muscular atrophy and fat infiltration.

To explore the application value of 3D printing technology in preoperative surgery plan and intraoperative auxiliary operation for adult kyphoscoliosis deformity. ⋯ The 3D print model can visually and clearly show the vertebral morphology and structure of adult kyphoscolisis and its spatial relationship with the adjacent vertebrae, blood vessels, and nerves, which provides a good and intuitive stereoscopic anatomical structure observation for the individualization of the surgical plan. Pre-simulation of operations to determine the internal fixation, fusion segment and osteotomy orthopedic way, may to provide a reference for actual clinical surgery, and can improve the accuracy and safety of surgery.
