This study evaluates the biomechanical alterations in patients post-surgery, focusing on the efficacy of an \u201c8\u201d bandage fixation system to promote optimal recovery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A three-dimensional (3D) model was constructed using CT data from a patient with hallux valgus. A quasi-static finite element analysis (FEA) was conducted in conjunction with gait analysis to evaluate the biomechanical changes at the osteotomy site under \u201c8\u201d shaped bandage fixation following hallux valgus surgery. The effects of the \u201c8\u201d shaped bandage on the stability of the osteotomy site and bone healing were investigated at three load points during the gait cycle.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>During the Loading Response (LR), Midstance (MSt), and Terminal stance TSt phases, the osteotomy end experienced maximum Von Mises stresses of 0.118, 1.349, and 1.485\u00a0MPa, respectively. Correspondingly, the maximum principal stresses, all of which were compressive along the <jats:italic>Z<\/jats:italic>-axis, were 0.11662\u00a0N, 1.39266\u00a0N, and 1.46762\u00a0N, respectively. Additionally, these phases showed a maximum relative total displacement of 0.848\u00a0mm and a maximum relative shear displacement of 0.872\u00a0mm.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>During the stance phase, the osteotomy end of the first metatarsal is predominantly subjected to compressive stress, with the relative displacement within the safe range to promote healing. The application of an \u201c8\u201d bandage for external fixation after surgery can maintain the dynamic stability of osteotomy sites post-minimally invasive hallux valgus correction during the gait cycle, thereby promoting the healing of the osteotomy ends.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fbioe.2024.1415617","type":"journal-article","created":{"date-parts":[[2024,7,30]],"date-time":"2024-07-30T04:22:16Z","timestamp":1722313336000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":6,"title":["Stability of osteotomy in minimally invasive hallux valgus surgery with \u201c8\u201d shaped bandage during gait: a finite element analysis"],"prefix":"10.3389","volume":"12","author":[{"given":"Xudong","family":"Sun","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ziyan","family":"Guo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuhan","family":"Cao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Binglang","family":"Xiong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yaxin","family":"Pan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weidong","family":"Sun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zixing","family":"Bai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2024,7,30]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"108","DOI":"10.1002\/1097-0150(2000)5:2<108::AID-IGS5>3.0.CO;2-2","article-title":"Accuracy of muscle moment arms estimated from MRI-based musculoskeletal models of the lower extremity","volume":"5","author":"Arnold","year":"2000","journal-title":"Comput.
