We aimed to describe a new surgical technique for hallux valgus percutaneous scarf like osteotomy (PSLO) without internal fixation, and to report the medium-term radiological and clinical outcomes.</p><p><strong>Hypothesis: </strong>A combination of a PSLO without internal fixation will lead to optimal results.</p><p><strong>Patients and methods: </strong>This retrospective case series reports on 126 cases involving 106 patients who underwent hallux valgus surgery with the PSLO technique +/- Akin, +/- lateral release. The osteotomy was stabilized by a bandage, and immediate weight bearing was allowed. The surgeries took place in 3 clinics in France from March 2016 to July 2017.</p><p><strong>Results: </strong>All radiological parameters: hallux valgus angle (HVA), the 1-2 intermetatarsal angle (IMA) and the distal metatarsal articular angle (DMAA) showed statistically significant improvement. The mean preoperative HVA, IMA and DMAA were 27.7 °, 14.2 ° and 12.7 ° respectively. The mean postoperative HVA, IMA and DMAA were 8.23 °, 8.1 ° and 3.8 °, respectively. Clinically, 97% were satisfied or very satisfied with the results, 92% could wear \"normal\" shoes (45 days - 6 months), 99% returned to the same athletic activities after surgery (3-5 months), and the average time to return to work was 4 weeks (1 day - 51 days).</p><p><strong>Discussion: </strong>The combination of scarf -like osteotomy and the percutaneous technique provide sufficient initial stabilization through the large horizontal area of contact between the fragments and the preservation of the attachment of the soft tissue. The lack of internal fixation significantly shortens the surgery time, cost, and reduces x-ray exposure without compromising the results.</p><p><strong>Level of evidence: </strong>III, retrospective comparative study.</p>","PeriodicalId":54664,"journal":{"name":"Orthopaedics & Traumatology-Surgery & Research","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141768099","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
