A review of screw implantation accuracy in thoracolumbar vertebral pedicle / 临床外科杂志

ABSTRACT

Pedicle screw fixation is widely applied to spinal surgery owing to its advantages of maitaining the stability of spine,promoting the bone graft fusing and so on. Remarkably implantation accu-racy is not only closely related to ultimate fixation,but also can affect the incidence and the severity of complications. Consequently,to improve screw implantation accuracy is one of the goals that spinal sur-geons always pursue. In recent years,newly-developed techniques have been preliminarily used in clinic. An overview on the progresses of these techniques in China and overseas is presented here.
