Progress on cervical anterior transpedicular screw fixators for lower cervical vertebrae / 中国骨伤

ABSTRACT

Compared with the traditional anterior and posterior operation,anterior transpedicular screw fixation (ATPS) has many advantages of hiomechanics, relative safety. Both problems of decompression and reconstruction can be resolved only through an anterior approach. A rather peculiar anatomic channel was used in ATPS, but no special tools was used in system supporting for anterior pedicle screw to place,so the indications of ATPS of lower cervical vertebrae is relatively narrow,it cannot replace of traditional anterior and posterior surgery. Problems of accurately inserting screws and the development of internal fixation device about ATPS is a hot spot of current research and a future direction. In recent years,many scholars have systematically studied the technique, and applied it in clinic gradually and achieved good effects. In order to improve the level of application,recent articles were analyzed retrospectively in this paper,and the studies of anatomy,biomechanical and clinical application of ATPS were reviewed.
