Reliability of the RUST Score for the Assessment of Union in Simple Diaphyseal Tibial Fractures

Abstract

th weeks, from the initial day of scoring, without revealing patients identity or fracture duration. Finally to check the reliability of RUST score, Intraclass correlation coefficient (ICC) with 95% confidence intervals (CI) was measured. Results: Overall agreement was statistically significant. The test-retest reliability was statistically significant, having value of 0.87, 0.95, 0.94, 0.98 and 0.97 respectively at each follow-up. The overall inter as well as intra-observer reliability of RUST score was collectively significant at each follow-up. Conclusions: The RUST score shows substantial improvements in reliability and produces reproducible results, either scored by an orthopaed ican or a radiologist.
