Medacta Shoulder System Humeral Reverse HIghcross PE Liner - Reverse shoulder prosthesis cup

Intended purpose

Device indicated for treatment of humeral fractures and for primary or revision total shoulder replacement in patients with a grossly rotator cuff deficient shoulder joint with severe arthropathy or a previously failed joint replacement. The patient’s joint must be anatomically and structurally suited to receive the selected implant(s), and a functional deltoid muscle is necessary to use the device. The glenoid baseplate is intended for cementless application with the addition of screws for fixation.

Functional description

The humeral reverse HC liner has a 5° wedged shape and can be coupled with the Humeral reverse metaphysis in two orientations: depending on the joint’s stability of the single patient, the surgeon can intraoperatively decide between an inclination of 145°, which allows for a wider range of motion at the cost of a reduced stability in total adduction, or 155°, which is associated to a higher stability and reduced range of motion.
