Biplane fluoroscopy derived humerus and scapula kinematics during arm elevation and rotation

This dataset contains torso, scapula, and humerus kinematics from 20 healthy subjects performing coronal plane abduction, scapular plane abduction, forward elevation, internal external rotation at 90º of abduction, and internal external rotation in adduction. The humerus and scapula were imaged at 100 Hz using a biplane fluoroscopy system. 3D models of the humerus and scapula were constructed from each subject’s CT scan. Model-based markerless tracking ascertained the 3D position and orientation of each bone model by semi-automatically aligning digitally reconstructed radiographs against each frame of the biplane fluoroscopy recordings. The kinematics of the torso were measured using skin marker motion capture.
