ObjectivePostoperative pain is a frequent problem after orthopedic procedures like hallux valgus surgery. The aim of this study was to evaluate whether ankle block improves early and mid-term functional outcomes and postoperative pain management after hallux valgus surgery in patients receiving general anesthesia.Subjects And MethodsThis randomized controlled trial investigated 60 patients who underwent hallux valgus surgery under general anesthesia. Patients were prospectively randomized into 2 groups: general anesthesia only (group A) and ankle block added to general anesthesia (group B). Age, body-mass index, tourniquet time, duration of surgery, first analgesic need time, perioperative analgesic regimen, visual analog scale (VAS), American Orthopedic Foot and Ankle Score (AOFAS), and length of hospital stay were recorded. Independent variables were analyzed by t test. Nonparametric data were analyzed by the Mann-Whitney U test.ResultsPatient age, demographics, and body mass indices were similar between the 2 groups. The average length of hospital stay was significantly longer in group A (p < 0.01). Group B had a longer time to first analgesic need than group A (p < 0.01). Patients in group B required less analgesic during the postoperative period. Preoperative VAS and AOFAS scores were not statistically dif ferent between the 2 groups. The postoperative day 1 VAS score was significantly lower in group B than in group A. Follow-up visits at 3, 6, and 12 months showed significantly lower VAS and higher AOFAS scores in group B than group A.ConclusionAnkle block added to general anesthesia may improve early and mid-term postoperative functional outcomes and postoperative pain management in patients who undergo hallux valgus surgery.© 2018 The Author(s) Published by S.
