一些髋部病变被归因于形态异常，其基本假设是异常的生物力学。然而，由于难以准确测量动态关节运动，关节层面的结构功能关系仍然难以量化。光学皮肤标记运动捕捉中固有的软组织伪影因体内髋关节的深度和关节周围的大量软组织而加剧。因此，骨骼形状和髋关节运动学之间的复杂关系比其他关节更难准确研究。在此，提出了一种结合计算机断层扫描 (CT) 关节造影、三维 (3D) 体积图像重建、双透视和光学运动捕获的协议，以准确测量髋关节的动态运动。总结了使用该协议应用双透视研究髋关节形态功能关系的技术和临床研究，并描述了数据采集、处理和分析的具体步骤和未来考虑因素。双透视准确捕捉人体关节的体内动态运动，可以相对于重建的解剖结构（例如关节运动学）进行可视化。在此，提出了量化日常生活负重活动期间髋关节运动学的详细协议，包括双透视与传统皮肤标记运动捕捉的集成。
Several hip pathologies have been attributed to abnormal morphology with an underlying assumption of aberrant biomechanics. However, structure-function relationships at the joint level remain challenging to quantify due to difficulties in accurately measuring dynamic joint motion. The soft tissue artifact errors inherent in optical skin marker motion capture are exacerbated by the depth of the hip joint within the body and the large mass of soft tissue surrounding the joint. Thus, the complex relationship between bone shape and hip joint kinematics is more difficult to study accurately than in other joints. Herein, a protocol incorporating computed tomography (CT) arthrography, three-dimensional (3D) reconstruction of volumetric images, dual fluoroscopy, and optical motion capture to accurately measure the dynamic motion of the hip joint is presented. The technical and clinical studies that have applied dual fluoroscopy to study form-function relationships of the hip using this protocol are summarized, and the specific steps and future considerations for data acquisition, processing, and analysis are described. Dual fluoroscopy accurately captures in vivo dynamic motion of human joints, which can be visualized relative to reconstructed anatomy (e.g., arthrokinematics). Herein, a detailed protocol to quantify hip arthrokinematics during weight-bearing activities of daily living is presented, including the integration of dual fluoroscopy with traditional skin marker motion capture.
