Intratendinous tears of the rotator cuff are, by definition, difficult to diagnose due to the absence of overt tendon disruption on both the bursal and articular surface of the rotator cuff. The authors describe the bubble sign, a bulging expansion of the rotator cuff tendon following injection of saline into the suspected lesion, as a useful indicator of an intratendinous tear of the rotator cuff.
根据定义，肩袖肌腱内撕裂由于肩袖滑囊面和关节面均无明显肌腱断裂而难以诊断。作者将气泡征（即在向疑似病变部位注射生理盐水后肩袖肌腱出现的膨隆扩张）描述为肩袖肌腱内撕裂的一个有用指标。
