The intraoperative recognition of rotator cuff tears continues to be a challenge in some cases, despite clinical suspicion, a physical examination suggesting a rotator cuff tear, and detection on preoperative imaging studies. Intraoperative identification can be elusive in partial tears including intratendinous tears and obscured full-thickness tears. The purpose of this Technical Note, and the associated technique video, is to discuss a visual sign for the detection of various rotator cuff tear pathologies. Derived from the dynamic fluid expansion and contraction of the affected tissues, this indicator is termed the arthroscopic "bellows" sign.
尽管存在临床怀疑、体格检查提示肩袖撕裂以及术前影像学检查发现病变，但在某些情况下，术中识别肩袖撕裂仍是一项挑战。术中识别部分撕裂（包括肌腱内撕裂和隐匿性全层撕裂）可能很困难。本技术说明及相关技术视频的目的是讨论一种用于检测各种肩袖撕裂病变的视觉征象。该征象源于受影响组织的动态液体扩张和收缩，被称为关节镜“风箱”征。
