Abstract:
BACKGROUND: Pedicle screw fixation is mainly used to treat thoracolumbar disorders, and accurate placement is the key to success; thereafter, how to improve the accuracy of placement and reduce the secondary nailing is an issue of concern.OBJECTIVE: To compare the advantages and disadvantages of various pedicle screw placement methods and their application value.METHODS: CNKI and PubMed databases were retrieved for clinical research concerning the pedicle screw fixation for thoracolumbar disorders published before May 2016 using the keywords of pedicle screw fixation, free-hand technique,3D-printing technology, computer navigation technology, clinical application prospect in English and Chinese,respectively. The repetitive literatures were excluded, and the advanced pedicle screw technologies were collected and evaluated in views of feasibility, universality and practicability.RESULTS AND CONCLUSION: (1) Computer-assisted navigation system and three-dimensional printing technology are the focus of research, but only applied in the treatment of pedicle congenital malformations or complicated cases. (2) Free-hand technique is still the most widely used, which is the essential skills that surgeons must master. (3) Traditional technology is still the mainstream in clinic, so improved preoperative planning, and individualized scheme are needed.
