167 Efficacy of Minimally Invasive Surgery on Hallux Valgus – a Systematic Review and Meta-Analysis

Abstract Aim The aim of this study is to evaluate the effect minimally invasive surgery over open for hallux valgus with respect surgical outcomes and patient reported outcomes. Method Medline Complete, PubMed, Cochrane Library, Scopus, SAGE Journals gray literature were searched. Primary focused on angle, intermetatarsal distal metatarsal articular angle. Secondary Outcomes included American Foot & Ankle Society Score (AOFAS), as well Pain a Visual Analogue Scale(VAS), satisfaction, complications, SF-36 questionnaire Manchester Oxford Questionnaire (MOXFQ). Results Conclusions 8 randomized trials 7 cohort studies identified (n=907). Radiological between similar techniques found have no significant difference pre-post operatively at final follow up. analogue scale scores be significantly lower in MIS groups compared (MICA v Scarf) short term Day 1 (P<0.00001) MD= -1.96 95% CI: -2.28, -1.65; I2 = 0%; Week 2 (P=0.001) -1.40; -2.26, -0.54; 6 (P=0.005) -1.50; -2.55, -0.45. There was statistical months (P=0.46) -0.16; -0.59, 0.27; or up (6 m >24m) (P=0.94) -0.02; -0.44, 0.41; 0%.). statistically important differences post-operative AOFAS across comparisons, whereas mean higher Open Scarf vs MICA (P 0.003); MD=-5.54; -9.19, -1.88. 0%.
