Abstract：
UNASSIGNED: Early diagnosis and fixation of fractures unlikely to unite can prevent months of morbidity. The Radiographic Union Score for Humeral fractures (RUSHU) is a summative scoring system developed to aid identification of patients at higher risk of developing humeral shaft non-union. Plain radiographs taken six weeks after injury are given a score between four and 12 based on signs of union. Our aim was to assess the validity of the RUSHU prognostic model in an external population.
UNASSIGNED: The radiographs of fifty-seven patients were scored independently according to RUSHU methodology by three reviewers (blinded to patient outcome). Interobserver intraclass correlation (ICC) was calculated.
UNASSIGNED: Of the cohort, six (10.5%) progressed to non-union after six months. We observed an interobserver ICC co-efficient of 0.89 (95%CI0.84,0.93) in RUSHU score at six weeks. Median score was significantly higher in the union cohort (10v5 p < 0.001). Using the score of < 8 to predict non-union gave an area under the ROC curve of 0.87 (95%CI 0.83,0.90).
UNASSIGNED: In this retrospective single-centre study, we have demonstrated good inter-rater reliability. We would suggest that the RUSHU model be assessed in further external validation studies. RUSHU has the potential to reduce morbidity of delayed treatment of non-union.

摘要：
■对不太可能合并的骨折进行早期诊断和固定可以预防数月的发病。肱骨骨折射线照相联合评分（RUSHU）是一种总结评分系统，旨在帮助识别发生肱骨干不愈合风险较高的患者。根据结合的迹象，受伤后六周拍摄的X光片得分在4到12之间。我们的目的是评估RUSHU预后模型在外部人群中的有效性。
■根据RUSHU方法，由三名评审员对57名患者的X光片进行了独立评分（对患者结局视而不见）。计算观察者间组内相关性(ICC)。
■在队列中，6人(10.5%)在6个月后进展为不工会。我们观察到6周时RUSHU评分的观察者间ICC系数为0.89(95CI0.84,0.93)。工会队列中的中位数得分明显更高（10v5p<0.001）。使用评分<8来预测不愈合给出了0.87的ROC曲线下面积(95CI0.83,0.90)。
■在这项回顾性单中心研究中，我们已经证明了良好的评分者间可靠性。我们建议在进一步的外部验证研究中评估RUSHU模型。RUSHU有可能降低不愈合延迟治疗的发病率。
