肩袖撕裂是引起肩关节疼痛、活动障碍的常见原因。通过身体的检查结合磁共振检查往往可以明确肩袖撕裂的范围和程度。如果损伤严重，无法自愈，疼痛和活动障碍将长时间存在。关节镜下肩袖修补术是一种微创的手术方法。 警告：请在有WIFI的场所观看视频，土豪请随意。Arthroscopic Rotator Cuff Repair 关节镜下肩袖修补术 Your doctor may recommend an arthroscopic ratator cuff repair if your rotator cuff is damaged. 当肩袖损伤时，医生可能会推荐进行关节镜下肩袖修补术。 The rotator cuff is made up of four muscles and tendons that anchor the head of upper arm bone（the humerus) securely into the socket of the shoulder joint. 肩袖由四块肌肉及其肌腱组成，锚固于上臂骨（肱骨）的头部，使其稳定地连在肩关节的臼窝。 The muscles of the rotator cuff pull on bands of tough, inelastic tissues called tendons to raise and rotate your arm, while keeping the shoulder joint stable. 肩袖的肌肉通过牵拉这些坚韧无弹性的称为肌腱的组织使胳膊上举及旋转，并维持肩关节的稳定。 A torn rotator cuff causes arm movement to be painful, limited or impossible, depending on the severity of the tear. 根据肩袖撕裂的严重程度，可能引起肩关节活动时疼痛、活动受限或无法活动。 In the most severe injuries, the tendon is torn away from the attachment on the head of humerus. Because blood supply to tendons is poor, a rotator cuff tendon is unable to heal itself after a complete tear, and you will need surgery. 在严重损伤时，肌腱从肱骨头的附着点撕脱。因为肌腱的血供很差，如果肩袖完全撕裂，它难以自愈，可能就需要手术治疗。 Your rotator cuff can be injured by falling, lifting, pulling, or doing repetitive over head arm motions, such as pitching, swimming and painting. In addition, the normal wear and tear that companies aging, weaking and break down the tendons. 肩袖损伤常发生于摔倒、提重物、拖拉或反复做上臂过顶动作， 比如投掷、游泳以及涮油漆。另外，随着年龄的增长，正常的磨损撕裂也会使肌腱变弱毁损。 Your surgeon will begin by making two small cuts in your skin to access the inside of the shoulder. Next, your surgon will insert an arthroscope, this device contains a light, a camera and tiny surgical tools. The arthroscope will project images onto a TV monitor to guide your surgeon's work. 首先，医生会在皮肤上做两个小切口，以进入肩关节内部。然后，医生会插入关节镜，这个设备包含有光源、摄像头，并插入一些微小的手术工具。关节镜能将图像投射到电视显示器上，引导医生手术。 Your surgon will make a few more small cuts, using small tools to examine your shoulder joint for unhealthy tissue, and repair the torn tendon. 医生还会作另外的切口，用小型工具检查肩关节内有没有病变组织，并修补撕裂的肌腱。 Next, your surgeon will drill a few small holes in your bone, where implants called suture anchors will be placed. Your surgeon will loop sutures through the anchors and stitched them to the repaired tendon to re-connect the tendon to the bone. 接着，医生会在骨头上钻一些小孔，在其中拧入称为缝合锚钉的植入物。医生可以将修复的肌腱通过锚钉环绕缝合，重新将肌腱与骨头连接起来。 The anchors and the sutures will gradully be absorbed into the healing tissues. 锚钉和缝线会逐渐被愈合的组织吸收。 At the end of the procedure, your surgeon will take out the arthroscopic tools and close your incisions with stitches. 在手术的最后，医生撤出关节镜工具，关缝合关闭切口。 After the procedure, your shoulder will be placed in a sling for support and protection. You will spend a few hours in a recovery room, and will most likely to go home the same day. 术后，将肩关节悬吊起来以支撑和保护。病人在恢复室观察几小时，往往当天就可以回家。 （胡佰文 听译） |
