Combining these 2 procedures in a single surgical session aims to address multiple deformities concurrently, although potential biomechanical interactions may affect long-term stability. This study investigates the clinical and radiographic outcomes of patients undergoing simultaneous MICA and DMMO, with a focus on hallux valgus recurrence.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>This retrospective, dual-international-centre study included 100\u2009feet from 98 patients who underwent concomitant MICA and DMMO (2nd\u20134th metatarsals) between 2019 and 2023 at 2 specialized minimally invasive surgery (MIS) centers. Inclusion criteria were symptomatic hallux valgus with central metatarsalgia unresponsive to conservative treatment and a minimum 12-month follow-up. Radiographic outcomes (hallux valgus angle [HVA], intermetatarsal angle [IMA]) and patient-reported outcomes (Patient-Reported Outcomes Measurement Information System [PROMIS], visual analog scale [VAS]) were assessed preoperatively and postoperatively at 3 and 12\u2009months. Radiographic recurrence was defined as HVA\u2009&gt;20 degrees at 12-month follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Significant improvements were observed in radiographic parameters, with the mean IMA decreasing from 14.65 degrees preoperatively to 9.8 degrees at 3\u2009months and 10.1 degrees at 12\u2009months (95% CI: 8.1-14,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      \u2009=\u2009.028), and the mean HVA decreasing from 39.6 degrees to 16.8 degrees and 22.6 degrees at the respective time points (95% CI: 12-41,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      \u2009=\u2009.024). Despite significant radiographic improvements, recurrence (HVA\u2009&gt;\u200920 degrees) was observed in 75 of 100\u2009feet (75%), although the degree of recurrence was mild (mean HVA 22.6 degrees at 12\u2009months vs 16.8 degrees at 3\u2009months). PROMIS physical function scores improved from 42.3\u2009\u00b1\u20096.2 to 59.9\u2009\u00b1\u20094.8 at 3\u2009months and 71.4\u2009\u00b1\u20095.1 at 12\u2009months (95% CI: 25.6-32.6,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      \u2009=\u2009.011), with a 12-month gain of 29.1\u2009points, surpassing the Minimal Clinically Important Difference (MCID) of 4.5 to 6.0.

The inconsistency between radiographic recurrence and patient satisfaction may be explained by pain relief and functional gains. Nevertheless, surgeons should recognize the substantially elevated risk of hallux valgus recurrence possibly related to biomechanical destabilization from concurrent DMMO and consider whether staged procedures may be more appropriate. Further long-term studies are needed to assess the durability of correction and refine patient selection criteria.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/10711007251372615","type":"journal-article","created":{"date-parts":[[2025,11,19]],"date-time":"2025-11-19T05:33:08Z","timestamp":1763530388000},"page":"10-18","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Combined Minimally Invasive Chevron-Akin and Distal Minimally Invasive Metatarsal Osteotomy for Hallux Valgus and Metatarsalgia: 12-Month Outcomes and High Radiographic Recurrence in a Dual-Center Study"],"prefix":"10.1177","volume":"47","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-5259-0854","authenticated-orcid":false,"given":"Gil","family":"Genuth","sequence":"first","affiliation":[{"name":"Assuta Medical Centre, Tel Aviv, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nadav","family":"Moses","sequence":"additional","affiliation":[{"name":"Wolfson Medical Centre, Holon, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Konstantin","family":"Hramov","sequence":"additional","affiliation":[{"name":"Assuta Medical Centre, Ashdod, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"Stavrou","sequence":"additional","affiliation":[{"name":"Flinders Medical Centre, Adelaide, South Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3300-6519","authenticated-orcid":false,"given":"Lukas D.","family":"Iselin","sequence":"additional","affiliation":[{"name":"Orthopadische Klinik Luzern AG, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,11,18]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1097\/CORR.0000000000002471"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1177\/1071100716656440"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1177\/10711007221114123"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1177\/24730114221112103"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.fcl.2024.11.008"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1177\/2473011416S00226"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1177\/1071100715598601"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.3113\/FAI.2007.0355"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00264-018-4006-8"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.fcl.2016.04.001"},{"key":"e_1_3_2_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.fas.2022.01.010"},{"key":"e_1_3_2_13_2","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.20.01178"},{"key":"e_1_3_2_14_2","doi-asserted-by":"publisher","DOI":"10.1177\/10711007221146195"},{"key":"e_1_3_2_15_2","doi-asserted-by":"publisher","DOI":"10.1177\/10711007211034849"},{"key":"e_1_3_2_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.fcl.2016.04.003"},{"key":"e_1_3_2_17_2","doi-asserted-by":"publisher","DOI":"10.1055\/a-0631-4924"},{"key":"e_1_3_2_18_2","doi-asserted-by":"publisher","DOI":"10.1177\/107110078400500208"},{"key":"e_1_3_2_19_2","doi-asserted-by":"publisher","DOI":"10.1177\/107110070102200107"},{"key":"e_1_3_2_20_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.fcl.2016.04.002"},{"key":"e_1_3_2_21_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.fuspru.2013.03.001"},{"key":"e_1_3_2_22_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.fcl.2024.03.004"}],"container-title":["Foot &amp; Ankle International"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/10711007251372615","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/10711007251372615","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/10711007251372615","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T21:23:52Z","timestamp":1777411432000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/10711007251372615"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,11,18]]},"references-count":21,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2026,1]]}},"alternative-id":["10.1177\/10711007251372615"],"URL":"https:\/\/doi.org\/10.1177\/10711007251372615","relation":{},"ISSN":["1071-1007","1944-7876"],"issn-type":[{"value":"1071-1007","type":"print"},{"value":"1944-7876","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,11,18]]}}}
