摘要
背景:以往的研究中仅对肱二头肌长头肌腱在肱二头肌腱沟入口偏离度进行定性描述,未进行定量测量。目的:通过分析健康志愿者肩关节中立位、外旋位和内旋位MRI之轴位图像上肱二头肌长头肌腱位置、方向及形态学改变,探讨肱二头肌长头肌腱MRI形态学特征以利临床评价肱二头肌长头肌腱。方法:纳入35名无症状志愿者,在肩关节中立位、外旋位、内旋位进行MR扫描。2名评价者对MR图像进行评价,排除标准为具有肩袖、喙肱韧带、上盂肱韧带、滑车韧带病灶或退行性改变者。一名测量者在轴位3D WATSc序列的上、中、下3个测量层面上对肱二头肌长头肌腱位置、方向及形态进行测量。结果与结论:健康志愿者肩关节中立位、外旋位和内旋位MR轴位图像上肱二头肌长头肌腱改变结果:①肱二头肌长头肌腱位置:中立位肱二头肌长头肌腱在内外方向的偏离度最大。②肱二头肌长头肌腱方向:肱二头肌长头肌腱的方向角度均为锐角,在中、下测量层面上,肩关节3个体位的肱二头肌长头肌腱角度之间的差异具有显著性意义。③形态:在下测量层面上,肩关节3个体位肱二头肌长头肌腱形态的改变具有显著性意义。结果显示健康志愿者肱二头肌长头肌腱位置、方向、形态与肩关节旋转体位具有潜在关联。
BACKGROUND： In previous studies, the eccentricity of long biceps tendon at the entrance to the groove has not been measured, but merely described qualitatively. OBJECTIVE： To characterize the position, orientation and shape of the long biceps tendon on MR images acquired in neutral position, external rotation, and internal rotation of the shoulder in asymptomatic volunteers, to explore MRI characteristics of the long biceps tendon for clinical assessment. METHODS： A total of 35 asyrnptomatic volunteers were included. MR scanning images were acquired in neutral position, external rotation and internal rotation of the shoulder. All MR images were evaluated by two radiologists, exclusive criteria were volunteers with lesions or any kind of degenerative changes to the rotator cuff tendons, coracohumeral ligament, superior glenohumeral ligament, and/or pulley fibers. The 3D WATSc sequence of long biceps tendon was measured at superior, middle, and inferior levels of the bicipital groove by a radiologist. The position, orientation, and shape of long biceps tendon were measured. RESULTS AND CONCLUSION： The results of MR images in neutral position, external rotation and internal rotation of the shoulder were followed： （1） The long biceps tendon eccentricity was maximal in the neutral position. （2） The orientations of long biceps tendon were acute angle, and the differences in long biceps tendon orientation were significant at middle and inferior measurement levels. （3） At inferior measurement level, the changes of shape of long biceps tendon showed significant differences. The findings showed that the position,orientation and shape of the long biceps tendon were slightly dependent on shoulder rotation and measurement level.
