Description
The Affinis Architec system features 3D planning and patient specific instruments (PSI) for the anatomic as well as the reverse Mathys shoulder portfolio.
Clinical challenges
- Few reliable bony landmarks to identify exact size and orientation of the residual glenoid vault1
- Small surgical window and limited exposure
- Abnormal glenoid morphology in around 40 % of cases2
- Challenging glenoid component placement3 as malpositioning is linked to increased radiolucent lines and poor clinical performance4
Benefit
- Adapt planning to your patients’ needs and individual morphology
- CT based 3D remodelling to visualise bony anatomy and preferred implant position
- Patented coracoid clip referencing reliable landmark and ensuring unique guide fit
- Small overall design allowing visibility on glenoid during guide use
- Accurate method in reproducing the surgical plan5
- Central pin guidance and indication of implant rotation
