An osteotomy was performed to simulate a Lapidus procedure, and the respective fixation methods were applied. Mechanical testing was conducted using a servo-hydraulic testing machine to evaluate constructs\u2019 load, contact force, contact area, and plantar gap.<\/jats:italic>\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      <jats:italic toggle=\"yes\">The 4-leg Inline Staple + Screw group demonstrated significantly increased joint contact force, joint contact area, and decreased plantar gap compared with the Plate + Screw group, both before and after cyclic testing.

These findings suggest a promising avenue for enhanced post-operative stability, which could translate into quicker patient recovery, improved fusion rates, and potentially lower non-union rates. Further clinical trials are warranted to validate these biomechanical advantages in patient outcomes.<\/jats:italic>\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence:<\/jats:title>\n                    <jats:p>\n                      <jats:italic toggle=\"yes\">Therapeutic, Level V: Bench Testing<\/jats:italic>\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/19386400241281898","type":"journal-article","created":{"date-parts":[[2024,10,13]],"date-time":"2024-10-13T06:54:57Z","timestamp":1728802497000},"page":"211-218","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Biomechanical Performance of 4-Leg Sustained Dynamic Compression Staples in First Tarsometatarsal Arthrodesis"],"prefix":"10.1177","volume":"19","author":[{"given":"Tian","family":"Wang","sequence":"first","affiliation":[{"name":"Surgical and Orthopaedic Research Laboratories, University of New South Wales, Sydney, NSW, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew","family":"Pelletier","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7465-3854","authenticated-orcid":false,"given":"James","family":"Johnson","sequence":"additional","affiliation":[{"name":"Enovis Foot &amp; Ankle, Atlanta, Georgia"},{"name":"Department of Mechanical Engineering, Colorado State University, Fort Collins, Colorado"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Courtney","family":"Kline","sequence":"additional","affiliation":[{"name":"Enovis Foot &amp; Ankle, Atlanta, Georgia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"William","family":"Walsh","sequence":"additional","affiliation":[{"name":"Surgical and Orthopaedic Research Laboratories, University of New South Wales, Sydney, NSW, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Craig","family":"Lareau","sequence":"additional","affiliation":[{"name":"New England Orthopedic Surgeons, Springfield, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Safranski","sequence":"additional","affiliation":[{"name":"Enovis Foot &amp; Ankle, Atlanta, Georgia"},{"name":"School of Materials Science and Engineering, Georgia Institute of Technology, Atlanta, Georgia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2024,10,13]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1177\/107110070002101004"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00064-005-1129-z"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.3113\/fai.2008.0927"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.3113\/fai.2009.0746"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1177\/2473011420940221"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.91BSUPP_I.0910164b"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1053\/j.jfas.2003.11.009"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.foot.2024.102069"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1007\/s40830-020-00294-y"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.1053\/j.jfas.2021.06.013"},{"issue":"15","key":"e_1_3_2_12_2","first-page":"1","article-title":"Tibiotalocalcaneal arthrodesis with intramedullary nails: mechanobiological background and evolution of compressive technology","volume":"1","author":"Dupont KMSN","year":"2019","unstructured":"Dupont KMSN, Bariteau JT.
