To explore the relationship of bone cement distribution and the puncture angle in the treatment of thoracolumbar compression fractures with unilateral percutaneous kyphoplasty (PKP). ⋯ Through measure imaging data before operation with PKP,the puncture point and entry point can be confirmed. According the measured data to puncture during operation, unilateral puncture can reach the distribution effect of the bilateral puncture in the treatment of thoracolumbar compression fractures.
-
To explore the correlation among prevertebral hyperintensity (PVH), sagittal canal diameter on MRI and neurologic function of patients after cervical vertebral hyperextension injury without fracture and dislocation. ⋯ The PVH and the disc-level canal sagittal diameter of the injury segment are associated with neurological status. The patients with multi-level sagittal canal stenosis are vulnerable to severe cervical spinal cord injury.
-
To analyze the complications of percutaneous kyphoplasty except bone leakge for the treatment of osteoporotic thoracolumbar vertebral compression fractures. ⋯ It's uncommon complication except bone cement leakge in treatment of osteoporotic thoracolumbar vertebral compression fractures with percutaneous kyphoplasty. The complication of cardiopulmonary system is a high risk in surgery; and cytotoxicity of bone cement,nervous reflex,fat embolism and alteration of intravertebral pressure may be main reasons.
-
To evaluate the clinical effects of posterior spinal transpedicular wedge osteotomy for kyphosis due to delayed osteoporotic vertebral fracture in elderly. ⋯ The clinical effect of posterior transpedicular wedge osteotomy for kyphosis due to delayed osteoporotic vertebral fracture was satisfactory, but manipulation during the operation should be cautious and prevent adjacent vertebral body fracture should be pay attention to prevent.

Radial corrective osteotomy is an established but challenging treatment for distal radial malunion. There is an ongoing discussion about whether an opening or closing-wedge osteotomy between should employed. The purpose of the present study was to retrospectively compare the clinical and radio graphic results between conventional opening-wedge osteotomy and closing-wedge technique. ⋯ The closing wedge osteotomy technique is an effective reconstructive procedure for the treatment of extra-articular distal radial malunion. It is significantly better than the opening-wedge osteotomy technique in terms of the restoration of ulnar variance, the extension-flexion arc of wrist motion, and the Mayo wrist score.
