Abstract
A reverse shoulder prosthesis system has a humeral stem with a lower cylindrical portion, an upper cylindrical portion, an intermediate conical portion, and a central axis, a large flat with a small recess having an axis forming an angle of about 150 degrees to the central axis. A humeral socket has an upper surface machined as a hemisphere and an attached backing plate formed with a projection as a male Morse taper received in the small recess of the stem. A glenoid head is formed in a hemispherical configuration with a cylindrical pocket. A baseplate has a cylindrical central part, an exterior part, a long cancellous bone screw machined in the center of the exterior part, and an enlarged interior projection for assembly to the head.
