We performed a biomechanical comparison of two rotator cuff repair techniques using fresh-frozen human cadavers. Nine pairs of cadaveric shoulders had standardized full-thickness tears made at the supraspinatus tendon insertion. One of each pair of the cadaveric shoulders was repaired by pulling the tendon into a bone trough in the humeral head using standard sutures. The remaining half of the pairs was repaired using anchor sutures. The repairs were tested using a servohydraulically operated material testing system. The anchor suture repair was significantly stronger than the standard suture technique irrespective of bone quality. Failure occurred predominantly through bone in the suture repairs and as a result of suture breakage in the anchor repairs. The anchors should be placed into the edge of the subchondral bone adjacent to the articular surface. The surgeon should direct the anchor so that the direction of the pull is approximately 90 degrees to the anchor, with the humerus at 30 degrees of abduction.
我们使用新鲜冷冻的人体尸体对两种肩袖修复技术进行了生物力学比较。九对尸体肩部在冈上肌腱止点处制作了标准化的全层撕裂。每对尸体肩部中的一个通过使用标准缝线将肌腱拉入肱骨头的骨槽进行修复。其余的尸体肩部通过使用锚钉缝线进行修复。使用伺服液压操作的材料测试系统对修复进行测试。无论骨质如何，锚钉缝线修复均明显强于标准缝线技术。缝线修复主要通过骨发生失效，而锚钉修复则是由于缝线断裂。锚钉应放置在与关节面相邻的软骨下骨边缘。外科医生应引导锚钉，使拉力方向与锚钉大致呈90度，肱骨外展30度。
