Today’s reversed shoulder arthroplasty patient demands the aesthetics, function and reliability of a healthy, natural shoulder. And while reversed technology has revolutionized shoulder replacement for patients worldwide, scapular notching, rotational limitations and prosthetic instability can be persistent clinical issues – in addition to restoring the patient’s own natural shoulder contour.

Now, Tornier is the first to take the reversed concept to new heights by lateralizing through the BIO-RSA technique. Pioneered by Professor Pascal Boileau (Nice, France), this technique, termed Bony Increased Offset for Reversed Shoulder Arthroplasty, achieves lateralization of the glenoid implant through a novel approach – using the patient’s own native bone.

Benefits of a Lateralized Reversed Prosthesis

Lateralizing the glenoid implant through the use of specialized components has been a viable approach to addressing common issues associated with reversed shoulder arthroplasty. Through BIO-RSA, a natural approach to lateralizing, these challenging clinical situations can be managed:

  • Achieving natural shoulder contour
  • Instability: eliminates slack in the remaining cuff muscles
  • Significantly reduced scapular notching
  • Improved internal/external rotation
