Abstract:

Objective To compare the similarities and differences of human thoracic pedicle anatomical structures in different countries by literature review, and to provide a theoretical basis for the selection of pedicle screws in thoracic surgery and improve the operation success rate and safety. Methods  To retrieve the related literature at home and abroad in CNKI, Pubmed, Web of knowledge and other database with the key words named "thoracic", "pedicle", "anatomy" and "measured", language limited to English or Chinese. Excluding the non-conforming literature, the remaining literature was divided into groups according to the origin of the experimental objects, and then the anatomical parameters of human thoracic vertebral pedicle in different countries were compared. Results A total of 20 articles were included after screening. The minimum value of pedicle height (PDH) was located at T1, and the maximum value was at T11 or T12, and the PDH varied relatively little at the middle levels of thoracic spine. In different countries, the pedicle width (PDW) decreased firstly and then increased from T1 to T12 and the minimum value was at T4 or T5. Although there were some differences in the numerical value of the pedicle horizontal (TPDA)angle in different countries, all of them were decreasing from T1 to T10. Conclusions The anatomical parameters of human thoracic vertebral pedicles in different countries show a similar trend with the change of vertebral body sequence, but there are some differences in anatomical parameters. Familiarity with the above anatomical differences is the key to improve the success rate and safety of surgery.
