摘要:

文题释义

肩袖损伤的肩胛骨运动学:肩关节是人体活动范围最大的关节,可内收外展、前屈后伸、内旋外旋。肩袖损伤后(冈上肌与冈下肌较常见),肩关节稳定性下降,活动度受限,肱骨过度上移,代偿性耸肩,导致肩肱节律被破坏。当进行肩外展或前屈时,肩胛骨的运动及位置改变,就会引起肩胛骨运动障碍。
双平面X射线:是由2台透视设备摆放成正交位(一般情况下)记录下测试动作的二维影像序列,用软件在虚拟的双平面系统中搭建坐标系,手动配准二维影像序列与三维骨性模型,获得受试关节运动时的数据。该技术具有无创、精准的优势,适合用于关节运动学的研究。

摘要
背景:由于肩胛骨运动复杂,为三维空间的六自由度活动,传统方法很难对其进行准确测量。基于双平面X射线的图像与模型匹配技术是近年来逐渐发展成熟的三维测量方法,拍摄时使用2台高速摄影机从正交方向进行投影拍摄,相比单一视角,这种方法在观测范围和减少平面外误差方面具有优势,适于开展肩胛骨运动学研究。
目的:应用X射线双平面图像结合图像-模型配准技术,探讨肩关节正常人群与肩袖损伤人群肩胛骨运动学的差异,为肩袖损伤患者的治疗和康复提供依据。
方法:选择2023年4月至2024年1月上海中医药大学附属光华医院收治的符合纳排标准的肩关节正常与肩袖损伤患者各10例。受试者完成肩关节CT扫描,建立肩胛骨的三维模型及局部坐标系;应用2台C臂机拍摄受试者肩关节外展过程的X射线双平面图像,将二维与三维图像进行配准,比较两组人群肩外展0°,15°,30°,45°,60°,75°,90°时的肩胛骨运动学差异,包括肩胛骨旋转角度、位移距离等。
结果与结论:①肩外展运动过程中,两组人群的肩胛骨均呈上旋,但肩袖损伤组的上旋幅度大于对照组,且在外展30°-90°时差异有显著性意义(P < 0.01);同时,两组人群的肩胛骨内旋均逐渐增加,但肩袖损伤组在外展45°-90°时显著大于对照组(P < 0.01);此外,两组的肩胛骨前后倾在外展15°-90°时差异均有显著性意义(P < 0.01),其中对照组在外展过程中肩胛骨后倾逐渐增大,而肩袖损伤组的肩胛骨除在15°-30°外展时轻微后倾外,其余位置均为前倾;②位移方面,在外展过程中肩袖损伤组的向上位移小于对照组,且在15°-90°时差异有显著性意义(P < 0.05),但两者横向及前后位移无明显差异(P > 0.05);③提示肩袖损伤可导致肩胛骨运动障碍,主要表现为肩外展过程中肩胛骨上旋、内旋的增加,以及反常的前倾,认识和治疗肩胛骨运动障碍对于肩袖损伤的治疗具有重要意义。

Abstract: BACKGROUND: Due to the complex movement of the scapula, which is a six-degree-of-freedom activity in three-dimensional space, it is difficult to measure it accurately using traditional methods. The image and model matching technology based on dual-plane X-ray is a three-dimensional measurement method that has gradually developed and matured in recent years. Two high-speed cameras are used to project and shoot from orthogonal directions. Compared with a single perspective, this method has advantages in observation range and reduction of out-of-plane errors, and is suitable for the study of scapula kinematics.
OBJECTIVE: X-ray biplane and image-model registration technology were used to explore the differences in scapular kinematics between normal individuals and patients with rotator cuff tears, providing a basis for the treatment and rehabilitation of rotator cuff tear patients. 
METHODS: From April 2023 to January 2024, 10 patients with normal shoulders and 10 patients with rotator cuff tears who met the inclusion criteria were enrolled from Guanghua Hospital Affiliated to Shanghai University of Traditional Chinese Medicine. The subjects underwent a shoulder CT scan to create a 3D model and a local scapular coordinate system. X-ray biplane images were taken during shoulder abduction with two C-arm machines. The 2D and 3D images were registered to compare scapular kinematic differences between the two groups at 0°, 15°, 30°, 45°, 60°, 75°, and 90° of abduction, including scapular rotation angle and displacement distance. 
RESULTS AND CONCLUSION: (1) During shoulder abduction, the scapula of both groups showed upward rotation, but the upward rotation of the rotator cuff tear group was greater than that of the control group, and the difference was significant when the abduction was 30°-90° (P < 0.01). At the same time, the scapula internal rotation of both groups gradually increased, but the rotator cuff tear group was significantly greater than the control group when the abduction was 45°-90° (P < 0.01). In addition, the anteroposterior tilt of the scapula of the two groups was significantly different when the abduction was 15°-90° (P < 0.01). The scapula posterior tilt of the control group gradually increased during abduction, while the scapula of the rotator cuff tear group tilted forward except for a slight posterior tilt at 15°-30° abduction. (2) In terms of displacement, the upward displacement of the rotator cuff tear group was less than that of the control group during abduction, and the difference was significant at 15°-90° (P < 0.05), but there was no significant difference in lateral and anterior-posterior displacement between the two groups (P > 0.05). (3) Rotator cuff tear can cause scapular dyskinesis, characterized by increased upward rotation, internal rotation, and abnormal forward tilt during shoulder abduction. Identifying and addressing scapular dyskinesis is crucial for treating rotator cuff tear.
