The different pedicle screw models are traditional trajectory (TT), Universal Spine System (USS), cortical bone trajectory (CBT), and CBT at the cranial level and pedicle screw (PS) at the caudal level (UP\u2010CBT). The stress distribution of the screws and connecting rods under different working conditions and the displacement of the injured vertebrae were compared and analyzed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>After the pedicle screw system was fixed, the stress under vertical compression was mainly concentrated at the proximal end of the screw, while the stress was mainly concentrated on the connecting rod during flexion, extension, lateral flexion, and rotation. The TT group had the greatest stress during the flexion, extension, and left and right rotation. The UP\u2010CBT group was most stressed when the left and right sides were flexed; the stress of the USS screw system was less than that of the other three models during flexion, lateral flexion, and rotation. The maximum von Mises stress values of pedicle screws in all exercise states were 556.2, 340.7, 458.1, and 533.4 MPa, respectively. In the USS group, the displacement of the injured vertebra was small in the flexion, and the left and right lateral flexion and the right rotation were higher than in the TT group and the CBT group. The maximum displacements of the injured vertebrae in all motion states were 1.679, 1.604, 1.752, and 1.777\u2009mm, respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Universal Spine System pedicle screws are relatively less stressed under different working conditions, the risk of breakage is small, and the model is relatively stable; CBT screws do not exhibit better mechanical properties than conventional pedicle screws and USS pedicle screws.<\/jats:p><\/jats:sec>","DOI":"10.1111\/os.12643","type":"journal-article","created":{"date-parts":[[2020,3,3]],"date-time":"2020-03-03T03:49:36Z","timestamp":1583207376000},"page":"601-608","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Treatment of Thoracolumbar Fractures Through Different Short Segment Pedicle Screw Fixation Techniques: A Finite Element Analysis"],"prefix":"10.1111","volume":"12","author":[{"given":"Tie\u2010nan","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Orthopaedics Affiliated Zhongshan Hospital of Dalian University  Dalian China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bao\u2010lin","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics Affiliated Zhongshan Hospital of Dalian University  Dalian China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rui\u2010meng","family":"Duan","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics Affiliated Zhongshan Hospital of Dalian University  Dalian China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ya\u2010shuai","family":"Yuan","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics Affiliated Zhongshan Hospital of Dalian University  Dalian China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ming\u2010jia","family":"Qu","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics Affiliated Zhongshan Hospital of Dalian University  Dalian China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuo","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics Affiliated Zhongshan Hospital of Dalian University  Dalian China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics Affiliated Zhongshan Hospital of Dalian University  Dalian China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tao","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics Affiliated Zhongshan Hospital of Dalian University  Dalian China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6559-2938","authenticated-orcid":false,"given":"Xiao\u2010bing","family":"Yu","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics Affiliated Zhongshan Hospital of Dalian University  Dalian China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,3,2]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000012190"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.21037\/qims.2016.12.04"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.otsr.2014.06.024"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000010066"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1097\/BRS.0b013e3181851bc2"},{"key":"e_1_2_5_7_1","first-page":"389","article-title":"Long\u2010term functional outcome after type A3 spinal fractures: operative versus non\u2010operative treatment","volume":"75","author":"Post RB","year":"2009","journal-title":"Acta Orthop Belg"},{"key":"e_1_2_5_8_1","doi-asserted-by":"crossref","first-page":"10","DOI":"10.1097\/00003086-198802000-00004","article-title":"New universal instrumentation in spinal surgery","volume":"227","author":"Cotrel Y","year":"1988","journal-title":"Clin Orthop Relat Res"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-199411000-00005"},{"key":"e_1_2_5_10_1","doi-asserted-by":"crossref","first-page":"140","DOI":"10.47102\/annals-acadmedsg.V40N3p140","article-title":"Radiological outcome of short segment posterior stabilisation and fusion in thoracolumbar spine acute fracture","volume":"40","author":"Yung AW","year":"2011","journal-title":"Ann Acad Med Singapore"},{"key":"e_1_2_5_11_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12891-016-0983-1"},{"key":"e_1_2_5_12_1","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-199306150-00003"},{"key":"e_1_2_5_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jocn.2018.04.039"},{"key":"e_1_2_5_14_1","doi-asserted-by":"publisher","DOI":"10.1097\/BRS.0b013e3181a4e667"},{"key":"e_1_2_5_15_1","first-page":"110","article-title":"Complications of anterior approaches to the thoracolumbar spine.
