Validation of single-plane fluoroscopy and 2D/3D shape-matching for quantifying shoulder complex kinematics

Quantifying shoulder kinematics is often fundamental to many clinical questions regarding the development and/or progression of orthopaedic conditions including rotator cuff disease and multidirectional instability. Traditional methods to non-invasively quantify kinematics include optical and electromagnetic motion capture. However, these methods are subject to skin motion artifact [1 –3]. Other studies quantified kinematics by attaching motion sensors to pins inserted directly into bones [4,5]. While these studies provide a more accurate description of joint motion, they are limited by small sample sizes due to the invasive nature of the methodology.
