To evaluate the interobserver and intraobserver reliability of the modified Radiographic Union Score for Tibia Fractures (mRUST) and the effect of rater experience in evaluation of femoral fractures.
Retrospective cohort study.
Single Level 1 trauma center.
PATIENTS/PARTICIPANTS: Patients 18-55 years of age with a femur shaft fracture.
Intramedullary nail fixation.
Interobserver and intraobserver reliability using the intraclass correlation coefficient.
The overall interobserver reliability was 0.96. Among fellowship-trained evaluators, the interobserver reliability was 0.94, and it was 0.92 among trainees. The overall intraobserver reliability was 0.98. The intraobserver reliability was 0.97 among fellowship-trained evaluators and 0.96 for trainees.
These results show high interobserver and intraobserver reliability of mRUST in the evaluation of radiographic healing for femur shaft fractures treated with intramedullary nail. This high reliability was further demonstrated throughout different postoperative healing time frames. In addition, mRUST appears to be reliable when used both by trainees and experienced surgeons for the evaluation of femur shaft fractures.
Diagnostic Level I. See Instructions for Authors for a complete description of levels of evidence.
评估改良的胫骨骨折放射学愈合评分（mRUST）的观察者间和观察者内可靠性，以及评估者经验对股骨骨折评估的影响。
回顾性队列研究。
单一的一级创伤中心。
患者/参与者：18至55岁的股骨干骨折患者。
髓内钉固定。
使用组内相关系数评估观察者间和观察者内可靠性。
观察者间总体可靠性为0.96。在接受过 fellowship 培训的评估者中，观察者间可靠性为0.94，在实习生中为0.92。观察者内总体可靠性为0.98。在接受过 fellowship 培训的评估者中，观察者内可靠性为0.97，实习生为0.96。
这些结果表明，mRUST 在评估髓内钉治疗的股骨干骨折的放射学愈合方面具有较高的观察者间和观察者内可靠性。这种高可靠性在不同的术后愈合时间范围内得到了进一步证明。此外，实习生和经验丰富的外科医生在使用 mRUST 评估股骨干骨折时似乎都是可靠的。
