Abstract
Advanced 3D CT imaging of the shoulder using metal artifact reduction techniques have been developed and validated in pre-clinical and patient population using microscribe and RSA techniques. These studies demonstrate these methods to be highly accurate and reproducible in the measurement of implant position and implant migrations. 3D CT imaging is being used to study the anatomic and clinical factors associated with glenoid implant loosening. This imaging modality does not require marker based image registration and utilizes imaging equipment that is readily available in the clinical setting.
