SUAREZ ZARRATE, Jessica A et al. Resultados de la cirugia minimamente invasiva y la cirugia abierta tipo scarf para la correccion del hallux valgus moderado y severo: Estudio observacional retrospectivo. Rev. Asoc. Argent. Ortop. Traumatol. [online]. 2018, vol.83, n.4, pp.233-241. ISSN 1852-7434.

Introduction: When pain associated with hallux valgus deformity is the main symptom and traditional treatment is not effective, then surgery is indicated. The aim of the study was to evaluate our experience with minimally invasive technique and scarf osteotomy using AOFAS scale and radiologically intermetatarsal angle correction, metatarsophalangeal angle, Regnauld scale and Reynolds criteria. Methods: Retrospective cohort observational study. Feet treated with minimally invasive technique and scarf osteotomy were included. Preoperative clinical data and those obtained at 3 and 6 months after surgery were reviewed to evaluate functionality, image findings on three angles, and Reynolds and Regnauld classifications. Results: A total of 123 patients were included, and 150 procedures were performed: minimally invasive surgery (44.7%) and scarf osteotomy (55.3%). Average age was 56 years (IQR 42-61), and 88.6% were women. No differences were observed at the immediate preoperative period, 3 months and 6 months for intermetatarsal angle between both techniques; however metatarsophalangeal angle was corrected (p<0.001) and AOFAS score (p<0.001) was better 3 months after the minimally invasive surgery. Conclusions: Both techniques provide correction to normal values. Minimally invasive technique achieved higher correction levels and a better AOFAS score. Incidence of acute complications was similar. Clinical studies on this issue are necessary to confirm these findings.
