我们通过动态超声检查（US）评估了冈上肌腱撕裂的肩部运动过程中喙肩韧带（CAL）的移位。 20 名单侧全层冈上肌腱撕裂的受试者（SST 组）和 20 名冈上肌腱完整的受试者（对照组）接受了动态超声检查。在被动和主动肩外展和内旋 (SAIR) 期间，在横向超声视图中测量双侧肩部的 CAL 位移。在 SST 组中，被动 SAIR 期间受影响肩部的 CAL 位移显着大于完整肩部（1.9 mm ± 0.8 mm 与 1.5 mm ± 0.5 mm，p = 0.01），但肩部之间没有显着差异（1.7 mm ±0.7 mm 与 1.7 mm ± 0.4 mm，p = 0.81）在活动 SAIR 期间。在对照组中，被动和主动 SAIR 期间肩部之间的 CAL 位移没有差异。 Thus, dynamic US revealed greater CAL displacement in shoulders with supraspinatus tendon tears than in intact ones during passive SAIR.动态超声可能有助于检测此类损伤的肩部运动学异常。 © 2012 骨科研究会。 Wiley periodicals, Inc. 出版。J Orthop Res 30:1430–1434, 2012
We evaluated coracoacromial ligament (CAL) displacement during motion in shoulders with supraspinatus tendon tears by dynamic ultrasonography (US). Twenty subjects with unilateral, full‐thickness supraspinatus tendon tears (SST group) and 20 subjects with intact supraspinatus tendons (control group) underwent dynamic US. The CAL displacement in their bilateral shoulders was measured in the transverse US view during passive and active shoulder abduction and internal rotation (SAIR). In the SST group, the CAL displacement was significantly greater in the affected shoulders than in the intact ones (1.9 mm ± 0.8 mm vs. 1.5 mm ± 0.5 mm, p = 0.01) during passive SAIR, but was not significantly different between the shoulders (1.7 mm ± 0.7 mm vs. 1.7 mm ± 0.4 mm, p = 0.81) during active SAIR. In the control group, no difference in the CAL displacement between the shoulders was noted during passive and active SAIR. Thus, dynamic US revealed greater CAL displacement in shoulders with supraspinatus tendon tears than in intact ones during passive SAIR. Dynamic US may help to detect abnormal kinematics in shoulders with such injury. © 2012 Orthopaedic Research Society. Published by Wiley Periodicals, Inc. J Orthop Res 30:1430–1434, 2012
