Research progress of lower cervical pedicle screw fixation / 中国组织工程研究

ABSTRACT

BACKGROUND: The lower cervical pedicle screw fixation is the most stable internal fixation of the cervical spine in biomechanics, which can penetrate the anterior, middle and posterior columns of the spine, effectively restore the sagittal sequence of the cervical spine, provide strong internal fixation and high fusion rate. OBJECTIVE: To review the relevant information of the anatomical structure of lower cervical pedicle, the biomechanical property of screw fixation, and three-dimensional printing technology-assisted screw placement at home and abroad. METHODS: PubMed and CNKI databases were searched for the articles concerning lower cervical pedicle screw fixation from January 1990 to January 2017. The key words were "lower cervical, pedicle screw, 3D printing technology" in Chinese and English, respectively. Totally 193 articles were researched, and the repetitive research, case report and meta-analysis were excluded. RESULTS AND CONCLUSION: (1) Finally 52 eligible articles were enrolled for result analysis. (2) Although it has a very high risk to fix lower cervical pedicle screw, the risk could be minimized or avoided through fully individualized evaluation preoperatively and precise fixation intraoperatively. So the lower cervical pedicle screw fixation has high clinical value.
