To investigate the feasibility and safety of the treatment for thoracolumbar fractures with pedicle screw at the fracture level and vertebroplasty via paraspinal approach. ⋯ The pedicle screw at the fracture level and vertebroplasty via paraspinal approach has the advantages of less invasive and blood loss, and could prevent the development of kyphosis and offers improvement of the spinal cord function. Furthermore, it could decrease the risks of postoperative back pain and the failure of instrumentation.

To explore efficacy of posterior reduction and interbody fusion in treating thoracolumbar fractures and dislocations. ⋯ Posterior reduction and rigid interbody fusion for the treatment of thoracolumbar fractures and dislocations can receive satisfactory fusion based on recovering normal spinal sequence

Compared with open surgery, percutaneous transforaminal endoscopic discectomy (PTED) for lumbar disc herniation (LDH) has advantages of minamilly invasive, little impact on stability of spine and rapid recovery. However, PTED by transforaminal approach has relatively limited indications and can not completely replace open surgery, due to different location of migrated herniated fragment, the level of pathological segment or presence of a high iliac crest. ⋯ However, not-standard manipulation, improper selection of indications or surgical approach has been attributed to the main reason for failure in PTED surgery. In view of this, the paper summaries indications, different approaches and methods, clinical efficacy and complications of PTED.

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.
