Reverse Total Shoulder Arthroplasty Alters Humerothoracic, Scapulothoracic, and Glenohumeral Motion During Weighted Scaption

<p>This dataset contains scapula&nbsp;and humerus kinematics from 10 healthy subjects, and 10 subjects post-operative to reverse total shoulder arthroplasty,&nbsp;performing&nbsp;scapular plane abduction (scaption) with and without a 2.2 kg&nbsp;(5 lb) handheld weight.&nbsp; 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&rsquo;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&#39;s torso. These data are available for download to aid researchers and clinicians in characterizing non-pathologic and reverse total&nbsp;shoulder arthroplasty&nbsp;motion during scapular plane abduction with and without a 5 lb handheld weight.</p>
