### Orthop J Sports Med 2018 ;6:2325967118784897 Rotator cuff disorders are the most common cause of shoulder pain in the general population. Unfortunately, the diagnosis of a rotator cuff tear is not always obvious and can present a diagnostic dilemma, especially in the older patients. When uncertainty exists, expensive imaging such as MRI may be required to aid diagnosis. When it comes to the clinical examination of a shoulder, there are an abundance of ‘special tests’, although individually these tests are limited in diagnostic accuracy for rotator cuff tears. Would not it be great if a battery of clinical tests could predict the likelihood of a tear? Such a tool would be convenient for the primary care physician whose access to ultrasound or MRI is often limited and costly. In this analysis of 301 patients, four diagnostic variables: male sex, Jobe’s test (empty can test), lift-off test and external rotation strength ratio were highly predictive of a rotator cuff tear in patients ≥45 years of age with >4 weeks of shoulder pain. Take home message: This diagnostic aid has the potential to improve clinical identification of rotator …

### Orthop J Sports Med 2018 ;6:2325967118784897 肩袖疾病是普通人群肩痛的最常见原因。不幸的是，肩袖撕裂的诊断并不总是很明显，可能会出现诊断困境，尤其是在老年患者中。当存在不确定性时，可能需要昂贵的成像（例如 MRI）来帮助诊断。当涉及肩部的临床检查时，有大量的“特殊测试”，尽管单独这些测试在肩袖撕裂的诊断准确性方面受到限制。如果一系列临床测试可以预测撕裂的可能性，那不是很好吗？这种工具对于初级保健医生来说是方便的，因为他们对超声或 MRI 的访问通常有限且昂贵。在对 301 名患者的分析中，有四个诊断变量：男性、Jobe 试验（空罐试验）、提离试验和外旋强度比高度预测 45 岁以上肩痛超过 4 周的患者出现肩袖撕裂。带回家的信息：这种诊断辅助工具有可能改善旋转肌的临床识别……
