Abstract:

BACKGROUND: More and more scholars have focused on cervical pedicle screws because of their unique three-dimensional stability.
OBJECTIVE: To review the anatomic characteristics of the cervical pedicle, and to investigate the safety and clinical application of cervical pedicle screws.
METHODS: The literature concerning the cervical pedicle screw internal fixation in recent years were extensively searched from CNKI and PubMed databases (1994-01/2010-09) using the keywords of “cervical pedicle screws” in Chinese and English. Forty-three articles of 292 were included in the result analysis. RESULTS AND CONCLUSION: Cervical pedicle screw fixation can obtain a good biomechanics based on its three-dimensional fixation. However, due to the special anatomic structures of the cervical pedicle adjacent to the surrounding, potential risks of blood vessel, nerve root and cervical spinal cord injuries, it is difficult to the internal fixation of cervical pedicle screws with a certain risk. The clinical application of pedicle screws should be individualized.
