CT based 3D remodelling to visualise bony anatomy and preferred implant position
Patented coracoid clip referencing reliable landmark and ensuring unique guide fit
About
The Affinis Architec system features 3D planning and patient specific instruments (PSI) for the anatomic as well as the reverse Mathys Affinis shoulder portfolio.
Clinical challenges:
- Few reliable bony landmarks to identify exact size and orientation of the residual glenoid vault [1]
- Small surgical window and limited exposure
- Abnormal glenoid morphology in around 40 % of cases [2]
- Challenging glenoid component placement [3] as malpositioning is linked to increased radiolucent lines and poor clinical performance [4]
- Small overall design allowing visibility on glenoid during guide use
- Accurate method in reproducing the surgical plan [5]
- Central pin guidance and indication of implant rotation
