Results of minimally invasive versus open surgery scarf type for correcting moderate and severe hallux valgus. Retrospective observational study.
Abstract
Introduction When pain associated to deformity in hallux valgus is the main symptom and traditional treatment is not effective, then surgical treatment is appropriate. This paper aims to evaluate our experience with minimally invasive technique and osteotomy SCARF-type, with AOFAS-scale and radiologicallyintermetatarsal angle correction, metatarsophalangeal angle, Regnauld scale and Reynolds criteria. Methods.Descriptive observational study retrospective-type. Surgically-handled feet through minimally invasive techniques and SCARF. Pre-surgical clinic information was checked and then 3 to 6 months post-surgery on functionality, imagery findings on three angles and Reynolds and Regnauld classification.Results 123 patients were included who had 150 procedures, minimally invasive surgery (44.7%) and SCARF (55.3%). Average age was 56 years old (IQR 42 – 61 years old), and most interventions were in women (88.6%). No differences between immediate pre-surgery were observed, 3 months and 6 months for intermetatarsalangle between both techniques; moreover, metatarsophalangeal angle was corrected (p=<0.001) and the AOFAS (p=<0.001) was better three months later with the minimally invasive surgery.Discussion Both techniques provide deformity correction to normal values. More and better correction levels were observed in AOFAS for minimally invasive technique with a statistically significant difference. Incidence on acute complications was similar. Clinical essays on this issue are relevant to confirm findings in this study.Downloads
