Minimally invasive foot surgery (MIS) has become a common procedure to treat various pathologies, and accuracy in the angle of metatarsal osteotomies is crucial to ensure optimal results. This randomized controlled trial with 37 patients investigates whether the implementation of a digital inclinometer can improve the accuracy of osteotomies compared to traditional freehand techniques. Patients were randomly allocated to group A (n = 15) receiving inclinometer-assisted surgery or group B (n = 22) receiving conventional surgery. Osteotomies were performed and outcomes were evaluated using an inclinometer. The inclinometer group showed a significant decrease in plantar pressure from 684.1 g/cm pretreatment to 449.5 g/cm post-treatment ( < 0.001, Cohen's d = 5.477). The control group decreased from 584.5 g/cm to 521.5 g/cm ( = 0.001, Cohen's d = 0.801). The effect size between groups was large (Cohen's d = -2.572, < 0.001). The findings indicate a significant improvement in accuracy and reduction in outliers when using an inclinometer, suggesting that this technology has the potential to improve surgical practice and patient outcomes in minimally invasive metatarsal osteotomies.
微创足部手术（MIS）已成为治疗各种疾病的常见方法，而跖骨截骨术角度的准确性对于确保最佳效果至关重要。这项有 37 名患者参与的随机对照试验研究了数字倾斜计的应用是否可以提高截骨术的准确性，与传统的徒手技术相比。患者被随机分配到接受倾斜计辅助手术的 A 组（n = 15）或接受传统手术的 B 组（n = 22）。使用倾斜计进行截骨术，并用其评估结果。倾斜计组的足底压力从术前的 684.1 g/cm 显著降低至术后的 449.5 g/cm（ < 0.001，Cohen's d = 5.477）。对照组从 584.5 g/cm 降至 521.5 g/cm（ = 0.001，Cohen's d = 0.801）。组间效应量较大（Cohen's d = -2.572， < 0.001）。这些发现表明，使用倾斜计时准确性显著提高，异常值减少，表明该技术有可能改善微创跖骨截骨术的手术实践和患者结果。
