The Affinis Inverse Bone Grafting Instruments complement the portfolio of the Mathys Affinis Inverse Shoulder System with an additional option for the treatment of patients with more complex glenoid morphologies in rotator cuff defect arthropathy or proximal humerus fracture. Developed for compatibility and application with the Metaglene CP, the smart instruments ensure extremely efficient implantation of the prosthesis.

Demonstrated clinical need

Patients suffering from glenoid defects with simultaneous inverse shoulder prosthesis implantation have been shown to account for a significant proportion of the total number of difficult-to-treat surgical patients. The new instruments now offer a fully guided surgical technique for defect balancing that supports the harvesting of six different bone grafts from the humeral head. The Affinis Inverse Metaglene CP with its longer central peg can accommodate the bone graft and allows reconstruction of the anatomical joint line after glenoid erosion and osseous defects using an inverse shoulder prosthesis.

With the 3D planning solutions MediCAD and Affinis Architec, Mathys furthermore supports operating surgeons in the preparation for surgery with the Affinis Inverse Metaglene CP in combination with a bone graft. Both solutions allow easy visualisation of the required graft as well as the placement of the implant, thereby improving the efficiency of interventions.

Shorter surgeries and lower risk of infection

Patients and operating surgeons benefit from reduced operating times thanks to the new Affinis Inverse Bone Grafting Instruments; in addition, infection risks and pain are reduced. The fully guided surgical technique does not require any additional surgical steps to harvest autograft material from the iliac crest or allograft material from the bone bank. Preparation of the removed bone graft is enhanced and simplified with the Affinis Inverse Bone Grafting Back Table Instrument which features in the set.

Wider range of treatment options

Thanks to its precise compatibility with the Affinis Inverse Metaglene CP, the new instruments offer operating surgeons additional treatment options for a wider range of glenoid morphologies. The simple operation moreover ensures logical workflows and efficient implantation of the prosthesis. Arranged in a separate tray with a clear layout, the Bone Grafting instruments can be seamlessly integrated into the existing tray landscape for Affinis Inverse or Affinis Fracture Inverse, giving users a better overview of the entire instrument set.
