This dataset contains scapula and humerus kinematics from 10 healthy subjects, and 10 subjects post-operative to reverse total shoulder arthroplasty, performing scapular plane abduction (scaption) with and without a 2.2 kg (5 lb) handheld weight. 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 bones are presented relative to each subject's torso. These data are available for download to aid researchers and clinicians in characterizing non-pathologic and reverse total shoulder arthroplasty motion during scapular plane abduction with and without a 5 lb handheld weight.
