Comparison of Minimally Invasive and Traditionally Open Surgeries in Correction of Hallux Valgus: A Meta-Analysis

This meta-analysis aimed to compare the clinical outcomes of minimally invasive surgery (MIS) and traditional open surgery for the correction of symptomatic hallux valgus. A literature search was conducted, and a total of 11 studies with 1166 (52.98%, cases) patients treated with MIS and 1035 (47.02%, cases) patients treated with tra-ditionally open surgery were included in the meta-analyses. The pooled data (odds ratio [OR] 6.28, 95% con fidence interval [CI] 3.20 to 12.32, Z = 5.35, p < .01) indicated that patients treated with MIS had a signi ficantly higher rate of excellent-good radiographic angular results than did patients treated with open surgery. However, the inciden-ces of complications (OR 0.67, 95% CI 0.24 to 1.91, Z = 0.75, p = .45), recovery time (standard mean difference-3.09, 95% CI-7.98 to 1.80, Z = 1.24, p = .22), and patient-reported satisfaction (OR 2.76, 95% CI 0.72 to 10.65, Z = 1.48, p =.14) were similar between patients with hallux valgus treated with MIS and patients treated with open surgery. Heterogeneity between the sources of the pooled data threatened the validity of our observations, and we used statistical methods that aimed to limit such biases. At this time, more high-quality studies are needed to con firm or refute the results of this investigation. (c) 2019 by the American College of Foot and Ankle Surgeons. All rights reserved.
