Functional Outcome of Cast Immobilisation and Functional Treatment in Management of Lateral Ankle Sprain (Grade 1 and 2)

Background: Pain and functional constraints from ankle sprains, which mostly impact the lateral ligamentous complex, can lead to the consumption of medical facilities and unavailability from workplace. No single technique is regarded as the most effective, despite the fact that this injury occurs frequently. This study evaluates the management modalities for lateral ankle sprain i.e. functional treatment and cast immobilization with pain and function as outcome variables.  Materials and methods: Seventy patients with lateral ankle sprains (grade 1 and 2) were included in this study. Each alternate participant was placed in a functional treatment (group A), while the other participants were placed in a cast immobilization group (group B). Every patient was assessed at a follow up of 2 and 6 weeks using Visual analog scale and Karlsson score for quantifying pain and function respectively.  Results: Thirty-two patients in the functional therapy group and twenty-eight in the cast immobilization group finished the study. The functional therapy group's mean age was 27.7 years, while the cast immobilization group's was 29.4 years. While both the right and left ankles were similarly impacted in the cast immobilization group, the dominant ankle involved in the functional treatment group was the right ankle in 19 patients and the left ankle in 16 patients. In both groups, a male preponderance was seen. By the end of the study, the mean differences between the two groups' Karlsson scores and visual analog scale scores were statistically significant.  Conclusion: Our study's findings show that a functional treatment outperforms immobilization in terms of both functional outcome and pain reduction.
