This implant is similar to other components of the Comprehensive Shoulder System, designed with convertibility in mind. Similar in size to the Comprehensive Reverse Standard Baseplate it may be implanted as a cement-free/press-fit baseplate. It features a boss for shear force resistance and the same central screw option found in the Comprehensive baseplates for excellent compression. Additional fixation is obtained with superior/inferior locking or nonlocking screws.
As a Primary Total Shoulder the Baseplate accepts an E1? liner and is designed to articulate with an anatomic humeral head.
In a revision setting, the poly can be removed and then the baseplate can accept a Comprehensive Reverse Shoulder Glenosphere for complete conversion of the glenoid without removal of the glenoid component.
