Since shoulder have a higher proportion of muscle which would have low electrical resistance, there could be more electrical damage to the rotator cuff muscles. We present a patient with acute rotator cuff tear by sudden uncontrolled jerking contractions caused by an electrical shock. A case of 42-year-old man with acute rotator cuff tear due to electrical injury to the shoulder was presented. Magnetic resonance imaging showed a full thickness tear and an undulating appearance of the peripheral end of the torn supraspinatus and infraspinatus muscle, suggesting an acute complete rupture. By arthroscopic surgery, the torn rotator cuff tendons were repaired with a suture bridge technique. At the final follow-up, the patient had a full, pain-free range of motion and had fully recovered shoulder muscle power.
由于肩部肌肉比例较高，其电阻较低，因此肩袖肌可能会受到更多电损伤。我们报告一例因电击导致突然不受控制的抽搐收缩而急性肩袖撕裂的患者。呈现了一名42岁男性因肩部电损伤导致急性肩袖撕裂的病例。磁共振成像显示全层撕裂，撕裂的冈上肌和冈下肌外周端呈波浪状外观，提示急性完全断裂。通过关节镜手术，采用缝合桥技术修复撕裂的肩袖肌腱。在最后一次随访时，患者活动范围完全且无痛，肩部肌肉力量已完全恢复。
