| Summary: | Abstract Anterior shoulder dislocation is a common orthopedic emergency. While many reduction methods require sedation, the FARES (FAst, REliable, and Safe) and Spaso methods allow reduction without anesthesia. We conducted a single-center, prospective, randomized controlled trial comparing the FARES and Spaso methods for anterior shoulder dislocation reduction. Patients aged 20 to 90 years were enrolled. The assigned closed reduction procedures were performed without patient sedation by trained orthopedic residents. If two attempts with the assigned method failed, the alternative method was used. The primary outcome was the first-attempt success rate, while secondary outcomes included overall success rate with both methods, reduction time, and pain scores. During November 2013 and December 2015, a total of 32 patients were randomized to the FARES (n = 17) or Spaso (n = 15) method. The first-attempt success rates were 71.6% for the FARES group and 80.0% for the Spaso group (p = 0.691). Among patients with failed closed reduction using the first technique, all patients in the Spaso-following-FARES group achieved successful reduction, whereas none in the FARES-following-Spaso group achieved successful reduction (p = 0.092). Pain scores during reduction were comparable between the FARES (4.29 ± 1.69) and Spaso (3.80 ± 2.65) techniques, with no statistically significant difference (p = 0.542). Follow-up data were available for 28/32 patients (87.5%; mean 5.3 ± 2.2 years). Four patients were lost (3 FARES, 1 Spaso; p = 0.726). Recurrent dislocation occurred in 3 patients (10.7%; 1 FARES, 2 Spaso; p = 0.947), and 2 patients (1 per group; p = 0.876) underwent surgery (arthroscopic stabilization and rotator cuff repair). Both the FARES and Spaso methods were effective for reducing anterior shoulder dislocations. Combining these methods may improve overall reduction rates.
