Discovery Elbow

The Discovery Elbow is designed to reproduce natural elbow anatomy and restore elbow mechanics.

It features spherical condyles on the hinge to allow for increased articular surface contact. Hinge laxity allows for proper anatomical varus/valgus movement in the elbow, and the spherical condyles can be assembled in the joint from a posterior approach.

Bearing Design
Spherical hinge reduces wear by providing increased articular surface contact area between the humeral and ulnar components
Varus/valgus laxity of 7 degrees
Optimized hinge size addresses individual anatomy by allowing any humeral component to be used with any ulnar component
Posterior hinge allows for assembly or disassembly without compromising either epicondyle
The hinge design has a top-loading screw mechanism which is easy to assemble and revise

Humeral Stem
Bowed stem reproduces anatomy through 5 degree lateral offset and 5 degree internal rotation
Cylindrical base preserves bone to minimize stress risers at the supracondylar columns¹
Anterior flange leads to enhanced rotational stability and helps prevent posterior subluxation, while avoiding the need for any additional bone block

Ulnar Stem
23 degree anterior neck angle of stem allows for anatomic axis of motion Polyethylene offset and lateral bow provide for reproduced anatomy
Clinically proven ArCom polyethylene reduces the possibility of stress hemi-delamination and early polyethylene failure^2,3
