Surgical correction consists of distal osteotomy of the first metatarsal and its lateral translation. However, in the case of hypermobility of the first cuneo-metatarsal joint (TMTJ), the associated Lapidus procedure is indicated to correct deformities along all three anatomical planes. Lapidus procedure is reported to have several contraindications and complications; for this reason, many surgeons proposed technical modification to the original procedure. We present the results of a novel surgical technique for hallux valgus correction with minimally invasive arthrodesis of first TMTJ without proximal correction of deformity, combined with a distal Austin-Chevron procedure. Materials and Methods: We retrospectively evaluated patients who underwent surgical correction of hallux valgus with our technique between January 2010 and January 2020. We collected data on demographics, anesthesiologic technique, associated surgical procedures, post-operative functional results, and complications. Dorso-plantar and lateral radiographs were performed at 6, 12, and 24 weeks after surgery or until fusion was documented. Clinical assessment considered gait analysis, pain or other disturbance, type of shoes worn, and use of orthosis. Results: A total of 240 patients were enrolled. AOFAS score, hallux valgus angle, and inter-metatarsal angle showed a significant improvement. Complications consisted of distal osteotomy non-union (1%), pain or protrusion of the screw (13%), and recurrence of deformity (2%). Overall, patients were very satisfied with the surgery in 192\/278 (69%) cases, moderately satisfied in 67\/278 (24%) cases, satisfied in 8\/278 (3%) cases, and dissatisfied in 11\/278 (4%) cases. Conclusions: Our novel surgical technique which combines in situ arthrodesis of the first tarso-metatarsal joint (TMTJ) with a distal Austin-Chevron procedure offers an effective alternative for correcting hallux valgus with first-ray hypermobility, minimizing complications associated with traditional methods.<\/jats:p>","DOI":"10.3390\/jpm15030081","type":"journal-article","created":{"date-parts":[[2025,2,25]],"date-time":"2025-02-25T10:55:48Z","timestamp":1740480948000},"page":"81","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Minimally Invasive Lapidus Arthrodesis Associated with Distal Osteotomy of M1: A Combined Procedure for Hallux Valgus Correction"],"prefix":"10.3390","volume":"15","author":[{"given":"Fabrizio","family":"De Marchi","sequence":"first","affiliation":[{"name":"Foot Surgery Unit, Department of Orthopedics, Villa Aprica Clinical Institute, 22100 Como, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ilaria Alice","family":"Crippa","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology and Critical Care, San Marco Hospital, 24040 Zingonia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"Bobba","sequence":"additional","affiliation":[{"name":"Orthopedic and Trauma Residency Program, University of Milan, 20122 Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alessandro","family":"Pudda","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, San Gavino Monreale Hospital, 09025 Sanluri, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2084-3983","authenticated-orcid":false,"given":"Filippo Maria","family":"Anghilieri","sequence":"additional","affiliation":[{"name":"Orthopedic and Trauma Residency Program, University of Milan, 20122 Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francesco","family":"Verde","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, IRCCS San Raffaele Hospital, 20127 Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3453-2043","authenticated-orcid":false,"given":"Filippo","family":"Familiari","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Magna Graecia University, 88100 Catanzaro, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lorenzo","family":"Monti","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, IRCCS San Raffaele Hospital, 20127 Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,2,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"322","DOI":"10.1016\/S1067-2516(99)80003-9","article-title":"The modified lapidus arthrodesis: A retrospective analysis","volume":"38","author":"Catanzariti","year":"1999","journal-title":"J.
