Reliability of modified Radiographic Union Scale for Tibial Fractures (mRUST) Scores in Ballistic Lower Extremity Trauma

The authors aimed to evaluate the reliability of the modified Radiographic Union Scale for Tibial Fractures (mRUST) in assessing union status in patients with ballistic lower extremity trauma and to determine the predictive value of 3-month mRUST scores for nonunion at 9 months postoperatively. The study found that while mRUST scores demonstrated moderate inter- and intra-rater reliability in ballistic fractures, they were effective in predicting nonunion in ballistic femoral fractures but only moderately so for tibial fractures.
