No known literature has reported the pedographic outcomes after HV correction with Minimally Invasive Chevron and Akin Osteotomy (MICA). Methods: A prospective cohort of 31 feet from 25 patients with moderate-to-severe symptomatic HV but without metatarsalgia underwent MICA and was evaluated using radiographic parameters and pedographic measurements (Footscan\u00ae, RSscan International, Olen, Belgium). Data were collected preoperatively and 3 months after surgery. Results: The radiographic parameters of the hallux valgus angle, intermetatarsal angle, distal metatarsal articular angle, first metatarsal head lateral shape, and lateral sesamoid grade significantly improved after MICA. The corrected first metatarsal length was significantly shortened by 2.3 mm, with consistent second metatarsal protrusion distance, lateral Meary\u2019s angle, and calcaneal pitch angle. Max force, max pressure, cumulative force, and cumulative pressure on the central metatarsals did not show significant changes between pre- and post-operative measurements, while these parameters significantly decreased in the hallux and first metatarsal area. Conclusion: MICA effectively corrects radiographic parameters but does not reduce central metatarsal loading in patients with moderate-to-severe HV without metatarsalgia.<\/jats:p>","DOI":"10.3390\/life14060734","type":"journal-article","created":{"date-parts":[[2024,6,7]],"date-time":"2024-06-07T04:38:56Z","timestamp":1717735136000},"page":"734","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Minimally Invasive Chevron Akin (MICA) Osteotomy Corrects Radiographic Parameters but Not Central Metatarsal Loading in Moderate to Severe Hallux Valgus without Metatarsalgia"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0945-7122","authenticated-orcid":false,"given":"Wei-Kuo","family":"Hsu","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, National Cheng Kung University Hospital, College of Medicine, National Cheng Kung University, Tainan 701, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tung-Hee Albert","family":"Tie","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, National Cheng Kung University Hospital, College of Medicine, National Cheng Kung University, Tainan 701, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4577-140X","authenticated-orcid":false,"given":"Wei-Li","family":"Hsu","sequence":"additional","affiliation":[{"name":"School and Graduate Institute of Physical Therapy, College of Medicine, National Taiwan University, Taipei 100, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-8441-4616","authenticated-orcid":false,"given":"Yan-Yu","family":"Chen","sequence":"additional","affiliation":[{"name":"School and Graduate Institute of Physical Therapy, College of Medicine, National Taiwan University, Taipei 100, Taiwan"},{"name":"Department of Orthopaedic Surgery, Show Chwan Memorial Hospital, Changhua 500, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,6,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"410","DOI":"10.5435\/JAAOS-D-19-00324","article-title":"Operative Approach to Adult Hallux Valgus Deformity: Principles and Techniques","volume":"28","author":"Shi","year":"2020","journal-title":"J.
