To explore the clinical effects of unilateral pedicle screw fixation and transforaminal lumbar interbody fusion (TLIF) through paraspinal muscle approach for recurrent lumbar disc herniation combined with lumbar instability. ⋯ Two methods both can obtain satisfactory effect in treating recurrent lumbar disc herniation combined with lumbar instability. Through the paraspinal muscle approach with unilateral pedicle screw fixation and TLIF has advantages of smaller surgical incision, shorter operation time, less intraoperative blood loss, faster relief in low back pain after operation, etc.

To analyze the surgical failure of lumbar spondylolisthesis and investigate the clinical effect of three vertebral reduction and fixation in revision of lumbar spondylolisthesis. ⋯ For the patients with lumbar spondylolisthesis, the reason of primary surgical failure mainly concerned with internal fixation loosening and breakage, and bone graft no-fusion. Revision surgery using three vertebral pedicle screw internal fixation, can get rigid fixation, complete decompression, bone graft fusion, combined with the guidance of the postoperative functional exercise for patients, can obtain satisfactory therapeutic effects.

To explore the reasons of secondary fracture after percutaneous vertebroplasty (PVP) for osteoporotic vertebral compression fractures (OVCFs) and discuss the measure of prevention and cure. ⋯ There is no significant difference in the subsequent fracture after PVP for the OVCFs different gender and fractured site, and also no significant difference in the adjacent and remote vertebral fractures. The report didn't support the biomechanical viewpoint that vertebral body stiffness increasing after PVP would lead to adjacent vertebral stress increasing and result easily in adjacent vertebral fracture. Secondary fracture occurs always in 6 months after operation, which is the natural course of osteoporosis.

To explore the effect of reduction on spino-pelvic balance in treating high-grade lumbar spondylolisthesis. ⋯ Surgical reduction for high-grade lumbar spondylolisthesis can improve spino-pelvic balance and acquire satisfactory outcomes.
