Scapular motion abnormality in rotator cuff tears is a well-known symptom, but its significance is not clear. Some authors consider it as a cause of rotator cuff tear, others as a consequence of the disease.
The aim of our study was to assess the changes in scapular motion in medium size full-thickness rotator cuff tear of degenerative origin compared to a healthy control group.
10 healthy (control group) and 9 subjects with a medium size (1-3 cm), complaining rotator cuff tear (study group) were included in our study, in whom we analyzed the movements of the shoulder girdle, including the scapula, during sagittal and scapular plane flexion using a VICON 3D motion capture system and U.L.E.M.A. motion analysis software. A two-sample t-test was used to test whether significant differences in scapular posterior tilting, upward rotation and protraction values were observed between the two groups for each humeral flexion angular position.
In the study group, a significant increase in scapular protraction was demonstrated in sagittal arm elevations at 40 and 50 degrees of arm elevation compared to the control group (p<0.05), whereas no significant difference in scapular upward rotation and posterior tilting was demonstrated. During scapular plane flexion, no significant difference in scapular movements was demonstrated compared to the control group.
Scapular dyskinesis is already present in cases of medium size rotator cuff tears. In scapular dyskinesis, a significant difference in protraction is first observed, which may affect scapular upward rotation and tilting as the tear continues to grow. Orv Hetil. 2023; 164(31): 1213-1221.
肩袖撕裂时肩胛骨运动异常是一种众所周知的症状，但其意义尚不清楚。一些作者认为它是肩袖撕裂的原因，另一些作者则认为它是疾病的结果。
我们研究的目的是评估与健康对照组相比，退行性起源的中等大小全层肩袖撕裂时肩胛骨运动的变化。
我们的研究纳入了10名健康受试者（对照组）和9名有中等大小（1 - 3厘米）、主诉肩袖撕裂的受试者（研究组），使用VICON 3D运动捕捉系统和U.L.E.M.A.运动分析软件分析了他们在矢状面和肩胛骨平面屈曲过程中包括肩胛骨在内的肩胛带运动。采用两样本t检验来检验两组在每个肱骨屈曲角度位置的肩胛骨后倾、上旋和前伸值是否存在显著差异。
在研究组中，与对照组相比，在手臂抬高40度和50度的矢状面手臂抬高过程中，肩胛骨前伸显著增加（p<0.05），而肩胛骨上旋和后倾无显著差异。在肩胛骨平面屈曲过程中，与对照组相比，肩胛骨运动无显著差异。
中等大小肩袖撕裂病例中已存在肩胛骨运动障碍。在肩胛骨运动障碍中，首先观察到前伸有显著差异，随着撕裂继续发展，这可能会影响肩胛骨的上旋和倾斜。《匈牙利医学周报》。2023年；164(31):1213 - 1221。
