However, the influence of the sextant angle (spiral level) definition on biomechanical performance has not been clarified. A conceptual finite element analysis was conducted to identify the advantages and drawbacks of spiral clavicle plates with various sextant angle definitions. Methods: Conventional superior and three different conceptual spiral plates with sextant angle definitions ranging from 45 to 135 degrees were constructed to restore an OTA 15-B1.3 midshaft clavicle fracture model. Three major loading scenarios (cantilever downward bending, axial compression, and axial torsion) were simulated to evaluate the reconstructed structural stiffness and the stress on the clavicle plate and bone screws. Results: The spiral clavicle plate demonstrated greater capability in resisting cantilever downward bending with an increase in sextant angle and showed comparable structural stiffness and implant stress compared to the superior clavicle plate. However, weakened resistance to axial compression load was noted for the spiral clavicle plate, with lowered stiffness and increased stress on the clavicle plate and screws as the spiral level increased. Conclusion: The spiral clavicle plate has been reported to offer multidirectional compatibility for the treatment of midshaft clavicle fractures, as well as geometric advantages in anatomical matching and reduced skin prominence after surgery. The current study supports that remarkable cantilever bending strength can be achieved with this plate. However, users must consider the potential drawback of lowered axial compression resistance in safety considerations.<\/jats:p>","DOI":"10.3390\/bioengineering11070713","type":"journal-article","created":{"date-parts":[[2024,7,15]],"date-time":"2024-07-15T15:17:06Z","timestamp":1721056626000},"page":"713","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Effect of Sextant Fixating Angle of Spiral Clavicle Plate on Biomechanical Stability\u2014A Preliminary Finite Element Study"],"prefix":"10.3390","volume":"11","author":[{"given":"Ming-Hsien","family":"Hu","sequence":"first","affiliation":[{"name":"Department of Post-Baccalaureate Medicine, College of Medicine, National Chung Hsing University, Taichung 402202, Taiwan"},{"name":"Department of Orthopedic, Show Chwan Memorial Hospital, Changhua 500009, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Po-Feng","family":"Su","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Changhua Christian Hospital, Changhua 500006, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kun-Jhih","family":"Lin","sequence":"additional","affiliation":[{"name":"Technology Translation Center for Medical Device, Chung Yuan Christian University, Taoyuan 320314, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wen-Chuan","family":"Chen","sequence":"additional","affiliation":[{"name":"Technology Translation Center for Medical Device, Chung Yuan Christian University, Taoyuan 320314, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7688-1671","authenticated-orcid":false,"given":"Shun-Ping","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Post-Baccalaureate Medicine, College of Medicine, National Chung Hsing University, Taichung 402202, Taiwan"},{"name":"Department of Orthopedics, Taichung Veterans General Hospital, Taichung 407219, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,7,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"691","DOI":"10.1016\/j.injury.2006.04.130","article-title":"Epidemiology of adult fractures","volume":"37","author":"Caesar","year":"2006","journal-title":"Injury"},{"key":"ref_2","first-page":"CD007121","article-title":"Conservative interventions for treating middle third clavicle fractures in adolescents and adults","volume":"2","author":"Lenza","year":"2009","journal-title":"Cochrane Database Syst.
