To explore the clinical effect of transforaminal lumbar interbody fusion (with single cage) combined with unilateral pedicle screw fixation in treating lumbar instability. ⋯ With strict indication and good skills, transforaminal lumbar interbody fusion (with single cage) combined with unilateral pedicle screw fixation in treating lumbar instability has advantages of smaller traumatic, less blood loss, faster recovery for the patient and can reduce the economic cost.
-
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.
-
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 evaluate therapeutic effects of Rigidfix cross pins combined with Intrafix pins for the reconstruction of anterior or posterior cruciate ligament under arthroscopy. ⋯ Reconstruction of anterior or posterior cruciate ligament under arthroscopy with Rigidfix cross pins and Intrafix pins fixation is feasible therapy for anterior or posterior cruciate ligament injuries, and the fixation is rigid. The therapy restores knee stability and provides a satisfactory short-term results.
