To evaluate the clinical outcomes of percutaneous kyphoplasty (PKP) in treating senile osteoporotic vertebral compression fractures under local anesthesia. ⋯ Percutaneous vertebral kyphoplasty is an effective method for treatment of senile osteoporotic vertebral compression fractures,which can expeditiously relieve pain and effectively recovery height of vertebral body and Cobb angle,it has advantages of minimal invasive. The results of short and mid-term follow-up were satisfactory, long-term follow-up is still needed. Correctly choosing the operative indication and improving surgical technique may avoid complications, especially bone cement leakage which is the most frequent complication.

To analyze the clinical effects of percutaneous transforaminal endoscopic technique in treating lumbar intervertebral disc herniation and sciatica. ⋯ Percutaneous transforaminal endoscopic technique is safe and effective method in treating lumbar disc herniation and sciatica,it can fleetly relieve pain and the patient can recover daily life and work after treatment.
-
To observe the change of behavior, pathological change of the spinal cord,and expression of brain-derived neurotrophic factor (BDNF) and brain-derived neurotrophic factor (NGF) on rats with spinal cord injury in order to explore the optimal time of BMSCs transplantation. ⋯ Allogeneic BMSCs transplantation is effective to stimulate the recovery of spinal cord function in rats with spinal cord injury,and the optimal time of BMSCs transplantation maybe at the 3 d after injury.
-
To study differences of multifidus muscle injury between Wiltse intermuscular approach and intramuscular stripping approach in one-level small incision transforaminal lumbar interbody fusion (TLIF) surgery. ⋯ The Wiltse intermuscular approach is an easy way for pedicle screw placement, and caused less paraspinal muscle damage than intra-muscular stripping approach, and had positive effects on less back pain.
-
To introduce the use of single arm external fixation assisted reduction and closed complex intramedullary nail fixation for the treatment of femoral shaft fracture operation method and to study its effects. ⋯ Unilateral fixator assisted closed reduction and interlocking intramedullary nail fixation for the treatment of femoral shaft fracture has following advantages: less trauma, simple operation, effective reduction, high rate of fracture healing, and low complication rate.
