TAKE-HOME POINTS
- Bone-preserving shoulder arthroplasty is now available and rapidly growing in the US.
- The calibrated, multiplanar instruments and prosthesis shown here allow surgeons to recreate the normal humerus shape with high precision.
- The elliptical, non-spherical design of the humerus prosthesis has shown improved shoulder kinematics compared to standard spherical prostheses.
- The implant rests on dense bone proximal to the anatomic neck where bone support is strong.
- Glenoid implant insertion is routinely performed using this technique and access is facilitated by the angled bone resections.
ABSTRACT
Proper reconstruction of proximal humeral anatomy is of primary importance to maximize patient outcomes after total shoulder arthroplasty. This article describes a new arthroplasty technique, where a fixed multiplanar bone resection is made and a novel implant, which is designed to precisely match the bone resection, is inserted.
