      Score (OMAS) in patients with unstable ankle fracture.

AB  - INTRODUCTION: The Olerud Molander Ankle Score (OMAS) is a widely used validated 
      Patient Reported Outcome Measure (PROM). For clinical research, it is important 
      to determine the Minimal Clinically Important Difference (MCID). The objective of 
      this study was to determine the MCID of the OMAS at several moments in the 
      follow-up, in a cohort of patients that underwent open reduction and internal 
      fixation of unstable ankle fractures with syndesmotic injury. MATERIALS AND 
      METHODS: Data for this descriptive study were extracted from a prospective 
      randomized controlled trial, the RODEO trial. The Dutch version of the OMAS was 
      completed at 3, 6 and 12-month follow-up and estimated at baseline. The used 
      anchor-based methods were: mean change and ROC curve. The distribution-based 
      methods were: 0.5SD and minimal detectable change (MDC). RESULTS: This cohort 
      included 148 patients. The mean OMAS score in the group with minimal improvement 
      between 3 and 6 months was 15.0 (SD 17.5, 95%CI 9.4-20.6) and between 6 and 
      12 months 9.5 (SD 17.1, 95% CI 3.1-15.9). The ROC curve between 3 and 6 months 
      resulted in a MCID of 12.5 (AUC 0.72) and between 6 and 12 months, the MCID was 
      7.5 (AUC 0.78). Using 0.5 SD, the MCID was 10.52 (SD 21.04) at 3 months, 11.37 
      (SD 22.73) at 6 months and 10.47 (SD 20.94) at 12 months. The MDC was 4.72 at 
      3 months, 5.20 at 6 months and 4.71 at 12 months. CONCLUSIONS: The calculated 
      MCID in patients following surgery for unstable ankle fractures ranges from 10.5 
      to 15.0 at 3-6-month follow-up and from 7.5 to 11.4 at 6-12-month follow-up, 
      depending on moment and method.
