To analyze the reason and strategy for failure of posterior pedicle screw short-segment internal fixation on thoracolumbar fractures. ⋯ Treatment of thoracolumbar fracture with posterior pedicle screw short-segment internal fixation may result in the complications such as bone nonunion ,internal fixation breakage and progressive kyphosis. Anterior reconstruction may be a good strategy for the failure of posterior operation.
-
To investigate the correlative factors of non-surgical vertebral fractures after percutaneous vertebroplasty (PVP) for osteoporotic vertebral compression fractures(OVCFs). ⋯ Recovery of vertebral body height may prefigure increasing risk of refracture in non-surgical vertebral body for the patient with OVCFs after PVP, and the adjacent vertebral fracture maybe concerned with injecting bone cement volume and recovery rate of vertebral body height.

To evaluate the value of the Centerpiece plate in the cervical single open-door laminoplasty and compared its advantages with conventional suture fixation methods. ⋯ Treatment of cervical spondylotic myelopathy with posterior single open-door laminoplasty and Centerpiece plate fixation can enlarge spinal canal volume,keep original cervical activity, improve postoperative JOA score. The method has obviously advantages compared with traditional suture fixation methods.
-
To explore the application value of the high-frequency ultrasound examination of the normal adult sciatic nerve. ⋯ High frequency ultrasound can be used as the first choice of the sciatic nerve when an imaging method preferred.

To investigate retrospectively the clinical effects and recurrence rate of 143 cases who underwent one level discectomy and followed up more than 10 years. To evaluate the outcome of patients in groups of different operating age and extents of disc herniation, and analyse whether difference exists in each group. ⋯ (1) Long-term followed-up of 143 cases prove mono-level lumbar discectomy is an option for disc herniation with good curative effect and lower recurrent rate, the technique should be the prior selection in dealing with patients with lumbar disc herniation. (2) 51% patients (19/37) in group under 30 years old endure persistent low back pain. (3) The long-term clinical effects in patients with severe disc protrution who underwent lumbar discectomy is worse than those patients with mild lumbar disc herniation.
