Semi-Rigid Cast versus Elastic Bandage in Grade II Lateral Ankle Sprain Treatment

Background. Treatment options for lateral ankle sprains continue to evolve as advances are made in terms of techniques and materials. Objectives. This study was performed to evaluate clinical outcomes and satisfaction between two immobilization materials, semi-rigid cast, and elastic bandages. Methods. This study was a non-randomized controlled study. Fifty-four patients have undergone immobilization for their sprained ankle and divided into two groups according to the material selection. There were 27 patients in each group. VAS score, Karlsson score, satisfaction scale, and presence of later ankle instability was obtained. Standard descriptive measurement, independent samples t-test, and chi-square test were used for statistical analysis. Results. The mean age was 25.29 ± 6.04 years old. Sports injury was accounted for 27 patients (50%), followed by internal damage (24 patients; 44.4%). VAS and Karlsson's scores were taken and validated by authors and significantly better in semi-rigid cast groups compared with the elastic bandage group in the first week and second-week follow-up. No significant differences in overall satisfaction and ankle stability after one year. Conclusion. This study showed that the application of semi-rigid cast yielded quicker recovery in patients with ankle sprain without any decline in satisfaction scale. Therefore, a semi-rigid cast could be preferred over elastic bandage for acute ankle sprains.
