The purpose of this study was to assess the biomechanical performance of IMHS versus plating. We hypothesized that IMHS fixation provides inferior stability to plating. Methods: Metacarpal fracture model with 3-mm of volar gapping in forty-four human cadaveric metacarpals was created. The specimens were divided into 5 groups: Group 1, 1.5-mm non-locking plate; Group 2, 1.5-mm locking plate; Group 3, 2.0-mm non-locking plate; Group 4, 2.0-mm locking plate; and Group 5, 2.4-mm short cannulated IMHS. A 4-point bending model was used to assess load-to failure (LTF) and stiffness. Results: Mean LTF was 364 \u00b1 130 N for 1.5-mm non-locking plates, 218 \u00b1 94 N for 1.5-mm locking plates, 421 \u00b1 86 N for 2.0-mm non-locking plates, 351 \u00b1 71 N for 2.0-mm locking plates, and 75 \u00b1 20 N for IMHS. Mean stiffness was 91 \u00b1 12 N\/mm for 1.5-mm non-locking plates, 110 \u00b1 77 N\/mm for 1.5-mm locking plates, 94 \u00b1 20 N\/mm for 2.0-mm non-locking plates, 135 \u00b1 16 N\/mm for 2.0-mm locking plates, and 55 \u00b1 15 N\/mm for IMHS. IMHS demonstrated significantly lower LTF and stiffness than plates. Conclusions: IMHS fixation of unstable metacarpal shaft fractures offers less stability compared to plating when loaded in bending. The LTF and stiffness of IMHS versus plating of metacarpal shaft fractures has not been previously quantified. Our results reveal that IMHS fixation is less favorable biomechanically and should be carefully chosen in regards to fracture stability.<\/jats:p>","DOI":"10.1177\/1558944716628485","type":"journal-article","created":{"date-parts":[[2016,5,6]],"date-time":"2016-05-06T15:22:26Z","timestamp":1462548146000},"page":"421-426","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":36,"title":["Comparison of Dorsal Plate Fixation Versus Intramedullary Headless Screw Fixation of Unstable Metacarpal Shaft Fractures"],"prefix":"10.1177","volume":"11","author":[{"given":"Eitan","family":"Melamed","sequence":"first","affiliation":[{"name":"New York University Hospital for Joint Diseases, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard M.","family":"Hinds","sequence":"additional","affiliation":[{"name":"New York University Hospital for Joint Diseases, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael B.","family":"Gottschalk","sequence":"additional","affiliation":[{"name":"New York University Hospital for Joint Diseases, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oran D.","family":"Kennedy","sequence":"additional","affiliation":[{"name":"New York University Hospital for Joint Diseases, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John T.","family":"Capo","sequence":"additional","affiliation":[{"name":"New York University Hospital for Joint Diseases, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2016,7,8]]},"reference":[{"key":"bibr1-1558944716628485","doi-asserted-by":"publisher","DOI":"10.1177\/1753193411424557"},{"key":"bibr2-1558944716628485","doi-asserted-by":"publisher","DOI":"10.1016\/S0363-5023(85)80067-8"},{"key":"bibr3-1558944716628485","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2010.04.032"},{"key":"bibr4-1558944716628485","doi-asserted-by":"publisher","DOI":"10.1053\/jhsu.2001.24145"},{"key":"bibr5-1558944716628485","doi-asserted-by":"publisher","DOI":"10.1007\/s00264-012-1524-7"},{"key":"bibr6-1558944716628485","doi-asserted-by":"publisher","DOI":"10.1016\/S0266-7681(03)00386-3"},{"key":"bibr7-1558944716628485","doi-asserted-by":"publisher","DOI":"10.1016\/j.hcl.2006.02.016"},{"key":"bibr8-1558944716628485","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2006.06.006"},{"key":"bibr9-1558944716628485","doi-asserted-by":"publisher","DOI":"10.1016\/0363-5023(93)90403-P"},{"key":"bibr10-1558944716628485","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2009.07.005"},{"key":"bibr11-1558944716628485","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-199606000-00008"},{"key":"bibr12-1558944716628485","doi-asserted-by":"publisher","DOI":"10.5435\/00124635-200810000-00004"},{"key":"bibr13-1558944716628485","doi-asserted-by":"publisher","DOI":"10.1007\/s11552-013-9562-1"},{"key":"bibr14-1558944716628485","doi-asserted-by":"publisher","DOI":"10.1097\/00000637-200208000-00015"},{"key":"bibr15-1558944716628485","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2014.11.027"},{"key":"bibr16-1558944716628485","doi-asserted-by":"publisher","DOI":"10.1016\/S0363-5023(85)80029-0"},{"key":"bibr17-1558944716628485","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2014.08.016"},{"key":"bibr18-1558944716628485","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2007.11.001"},{"key":"bibr19-1558944716628485","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2012.09.029"},{"key":"bibr20-1558944716628485","doi-asserted-by":"publisher","DOI":"10.1016\/S0363-5023(84)80145-8"}],"container-title":["HAND"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1558944716628485","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/1558944716628485","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1558944716628485","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T07:28:19Z","timestamp":1777447699000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1558944716628485"}},"subtitle":["A Biomechanical Study"],"short-title":[],"issued":{"date-parts":[[2016,7,8]]},"references-count":20,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2016,12]]}},"alternative-id":["10.1177\/1558944716628485"],"URL":"https:\/\/doi.org\/10.1177\/1558944716628485","relation":{},"ISSN":["1558-9447","1558-9455"],"issn-type":[{"value":"1558-9447","type":"print"},{"value":"1558-9455","type":"electronic"}],"subject":[],"published":{"date-parts":[[2016,7,8]]}}}
