To explore the best entry point and trajectory of anterior cervical screw in the cervical screw by radiological studies, and provide reference for clincal application. ⋯ The best entry point of C3,C4 and C5 were located in the center line and slightly to opposite vertebral body side and upper 1/4 area; C7 were located the vertebral body side and upper 2/4 area; C6 were located between them. The best insertion point were extraversion 38 degrees to 45 degrees, C3 to C5 increased graduallly, C5 to C7 decreased on horizontal axis; On sagittal view, C3,C4 for head 5 degrees to 10 degrees, C5 were basic level, C6,C7 for tail 5 degrees to 10 degrees. The anterior cervical pedicle screw for lower cervial spine is a good and feasible internal fixation.

To explore efficacy of modified funnel method for transpedicular bone grafting in treating thoracolumbar vertebras fracture. ⋯ Posterior pedicle screw fixation, reduction and modified funnel method for transpedicular autogenous iliac bone grafting is a feasible and safe method for the treatment of thoracolumbar vertebras fracture. It can effectively prevent bone loss of injured vertebral height, progressive deformity of kyphosis, and keep spinal movement function at the maximum.
-
To evaluate clinical effects of pedicle fixation without bone fusion in treating thoracolumbar fractures through paraspinal approach. ⋯ For flexion and burst thoracolumbar fractures without nervous injury, pedicle fixation without bone fusion is a good method,which has advantages of minimally invasive, rapid recovery, and maintain spinal motion segment.
-
To evaluate the preliminary clinical outcomes of percutaneous endoscopic lumbar discectomy (PELD) for patient with upper lumbar disc herniation and failing to respond to conservative treatment. ⋯ PELD is effective in treating patient with upper lumbar disc herniation failing to respond to conservative treatment.
