The purpose of this study was to quantify deltoid release with standard linear versus curvilinear plates used in the repair of proximal humeral fractures.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>METHODS:<\/jats:title>\n            <jats:p>Seven nonpaired, fresh-frozen, clavicle-to-fingertip cadaveric shoulders met the inclusion criteria for this study. Four different proximal humerus implants were tested. One of these plates was curvilinear (89 mm), and the other 3 plates were linear (85, 98, 109 mm in length). Plates were compared based on the amount of deltoid insertion released for proper plate positioning. An analysis of variance with post hoc Tukey tests was conducted to compare mean deltoid disruption across the 3 shortest plate types from each manufacturer. A linear regression analysis was conducted to analyze the effect of plate length on mean deltoid release.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>RESULTS:<\/jats:title>\n            <jats:p>The mean deltoid insertion length was 39.6 \u00b1 8.6 mm (n = 7). The curvilinear plate (89 mm) required the least amount of average deltoid release at 4.1 \u00b1 4.5 mm, or 12.1% of the deltoid insertion. Independent analysis of variance, including the 3 shortest plates from each manufacturer, found a significant effect of which plate was used on the amount of deltoid disruption that resulted (<jats:italic toggle=\"yes\">F<\/jats:italic>(2, 18) = 18.0, <jats:italic toggle=\"yes\">P<\/jats:italic> &lt; 0.001, <jats:italic toggle=\"yes\">\u03c9<\/jats:italic> = 0.6). A linear regression including all 4 plates demonstrated a statistically significant direct relationship between the plate length and the mean deltoid released (y = 0.6x \u2212 43.8, r<jats:sup>2<\/jats:sup> = 4).<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>CONCLUSION:<\/jats:title>\n            <jats:p>This study demonstrates that proximal humerus plate length has a direct relationship with the amount of deltoid released during plating. Although deltoid disruption is length dependent, plate shape (curvilinear vs. linear) could also be contributory. When comparing a curvilinear and a linear plate of similar lengths, the curvilinear plate resulted in less mean deltoid release.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1097\/bot.0000000000002871","type":"journal-article","created":{"date-parts":[[2024,7,17]],"date-time":"2024-07-17T12:01:26Z","timestamp":1721217686000},"page":"566-570","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":1,"title":["Quantifying Distal Deltoid Disruption With Linear versus Curvilinear Plating of Proximal Humerus Fractures: A Cadaveric Study"],"prefix":"10.1097","volume":"38","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5118-8099","authenticated-orcid":false,"given":"Youssef","family":"Galal","sequence":"first","affiliation":[{"name":"Banner University Medical Group, University of Arizona College of Medicine - Phoenix, Phoenix, AZ; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arjun","family":"Vohra","sequence":"additional","affiliation":[{"name":"Banner University Medical Group, University of Arizona College of Medicine - Phoenix, Phoenix, AZ; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patrick","family":"Saunders","sequence":"additional","affiliation":[{"name":"Banner University Medical Group, University of Arizona College of Medicine - Phoenix, Phoenix, AZ; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ben","family":"Paul","sequence":"additional","affiliation":[{"name":"Banner University Medical Group, University of Arizona College of Medicine - Phoenix, Phoenix, AZ; and"},{"name":"Creighton University Health Sciences - Phoenix, Phoenix, AZ."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Clayton","family":"Hui","sequence":"additional","affiliation":[{"name":"Banner University Medical Group, University of Arizona College of Medicine - Phoenix, Phoenix, AZ; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephen","family":"Yao","sequence":"additional","affiliation":[{"name":"Banner University Medical Group, University of Arizona College of Medicine - Phoenix, Phoenix, AZ; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Evan","family":"Lederman","sequence":"additional","affiliation":[{"name":"Banner University Medical Group, University of Arizona College of Medicine - Phoenix, Phoenix, AZ; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"McKee","sequence":"additional","affiliation":[{"name":"Banner University Medical Group, University of Arizona College of Medicine - Phoenix, Phoenix, AZ; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anup","family":"Shah","sequence":"additional","affiliation":[{"name":"Banner University Medical Group, University of Arizona College of Medicine - Phoenix, Phoenix, AZ; and"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","reference":[{"key":"R1-20250614","doi-asserted-by":"crossref","first-page":"2117","DOI":"10.1016\/j.jse.2017.05.029","article-title":"Epidemiology of proximal humeral fractures: a detailed survey of 711 patients in a metropolitan area","volume":"26","author":"Passaretti","year":"2017","journal-title":"J Shoulder Elbow Surg"},{"key":"R2-20250614","doi-asserted-by":"crossref","first-page":"365","DOI":"10.1080\/000164701753542023","article-title":"The epidemiology of proximal humeral fractures","volume":"72","author":"Court-Brown","year":"2001","journal-title":"Acta Orthop Scand"},{"key":"R3-20250614","doi-asserted-by":"crossref","first-page":"137","DOI":"10.1016\/j.jseint.2021.08.006","article-title":"Trending a decade of proximal humerus fracture management in older adults","volume":"6","author":"Patel","year":"2022","journal-title":"JSES Int"},{"key":"R4-20250614","doi-asserted-by":"crossref","first-page":"2072","DOI":"10.1016\/j.jse.2019.03.034","article-title":"Nationwide trends in management of proximal humeral fractures: an analysis of 77,966 cases from 2008 to 2017","volume":"28","author":"McLean","year":"2019","journal-title":"J Shoulder Elbow Surg"},{"key":"R5-20250614","doi-asserted-by":"crossref","first-page":"1077","DOI":"10.2106\/00004623-197052060-00001","article-title":"Displaced proximal humeral fractures: I.
