本研究的目的是利用三维（3D）到二维（2D）模型到图像配准技术评估健康肩关节在动态轴向旋转和肩胛平面完全外展过程中的运动学，分析了10名健康参与者在轴向旋转和肩胛平面外展过程中的动态盂肱运动学。使用平板射线照相探测器拍摄轴向旋转和肩胛平面外展的连续射线照相图像。参与者接受计算机断层扫描，以生成虚拟数字重建X线照片。然后将基于密度的数字重建射线照片与使用图像相关性获得的系列射线照相图像进行比较。这些3D到2D模型到图像配准技术确定了动态全轴向旋转和肩胛平面全外展过程中肱骨和肩胛骨的3D位置和方向。肱骨头中心平均向后平移2.5 +/-3.1 mm，早期向上平移1.4 +/-1.0 mm，然后在外旋运动的后期平均向前2.0 +/-0.8 mm。盂肱外旋角对肱骨头中心的前/后（A/P）和上级/下（S/I）平移有显著影响（均p <0.05）。33.6肩胛平面外展时盂肱关节外旋+/-15.6A度。在肩胛平面外展过程中，肱骨头中心在早期平均向上平移0.6 +/-0.9 mm，然后在晚期向外侧平移1.7 +/-2.6 mm，在早期平均向内侧平移0.4 +/-0.5 mm，然后在晚期向外侧平移1.6 +/-1.0 mm。肱骨外展角对肱骨头中心的S/I和L/M平移有显著影响本研究调查了肱骨相对于肩胛骨的3D平移：在肩胛平面完全外展期间，肱骨相对于肩胛骨向外旋转33.6A度，并且在内收位置的外旋运动期间，肱骨头中心向后平均平移2.5 mm。运动学数据将提供重要的见解，以评估病理性肩关节的运动学。对于临床相关性，动态健康肩关节运动学的定量评估可能是评估病理性肩关节的生理指标。
The purpose of this study was to evaluate the kinematics of healthy shoulders during dynamic full axial rotation and scapular plane full abduction using three-dimensional (3D)-to-two-dimensional (2D) model-to-image registration techniques.Dynamic glenohumeral kinematics during axial rotation and scapular plane abduction were analysed in 10 healthy participants. Continuous radiographic images of axial rotation and scapular plane abduction were taken using a flat panel radiographic detector. The participants received a computed tomography scan to generate virtual digitally reconstructed radiographs. The density-based digitally reconstructed radiographs were then compared with the serial radiographic images acquired using image correlations. These 3D-to-2D model-to-image registration techniques determined the 3D positions and orientations of the humerus and scapula during dynamic full axial rotation and scapular plane full abduction.The humeral head centre translated an average of 2.5 +/- 3.1 mm posteriorly, and 1.4 +/- 1.0 mm superiorly in the early phase, then an average of 2.0 +/- 0.8 mm inferiorly in the late phase during external rotation motion. The glenohumeral external rotation angle had a significant effect on the anterior/posterior (A/P) and superior/inferior (S/I) translation of the humeral head centre (both p < 0.05). 33.6 +/- 15.6A degrees of glenohumeral external rotation occurred during scapular plane abduction. The humeral head centre translated an average of 0.6 +/- 0.9 mm superiorly in the early phase, then 1.7 +/- 2.6 mm inferiorly in the late phase, and translated an average of 0.4 +/- 0.5 mm medially in the early phase, then 1.6 +/- 1.0 mm laterally in the late phase during scapular plane abduction. The humeral abduction angle had a significant effect on the S/I and lateral/medial (L/M) translation of the humeral head centre (both p < 0.05).This study investigated 3D translations of the humerus relative to the scapula: during scapular plane full abduction, the humerus rotated 33.6A degrees externally relative to the scapula, and during external rotation motion in the adducted position, the humeral head centre translated an average of 2.5 mm posteriorly. Kinematic data will provide important insights into evaluating the kinematics of pathological shoulders. For clinical relevance, quantitative assessment of dynamic healthy shoulder kinematics might be a physiological indicator for the assessment of pathological shoulders.
