A simplified baseplate for shoulder reconstruction procedures offers an alternative to bone grafting and eccentric reaming for patients with glenoid defects.

The Zimmer Biomet (Warsaw, IN, USA) Comprehensive Augmented Baseplate boasts a simplified circular design at three augment heights (3, 5, and 7mm), allowing placement in any orientation to accommodate various bone anatomies and the full spectrum of glenoid bone wear. The circular design also permits bone ingrowth into the rim of the baseplate for optimal fixation. Features include a modular 6.5 mm central compression screw for enhanced stability; a central boss for sharing the sheer load being transferred to the glenoid; and tricalcium phosphate/hydroxyapatite (TCP-HA) layered over a polyphenylene sulfide (PPS) coating for fixation.

By providing relevant sizing, it also allows a conservative approach to bone removal, thus preserving bone stock if (and when) a future revision procedure becomes necessary, and minimizing the potential challenges of removing well-fixed humeral stems by allowing conversion to a reverse shoulder using any of the existing Comprehensive stems. The Comprehensive Augmented Baseplate is a component of the Comprehensive Reverse Shoulder System, a next-generation reverse shoulder prosthesis engineered to offer high-quality intraoperative flexibility.

“The new Augmented Baseplate rounds out Zimmer Biomet's Comprehensive Shoulder portfolio and provides solutions that help surgeons with difficult glenoid deformity cases,” said Orsa Britton, vice president and general manager of Zimmer Biomet's global Extremities business.

Up to 50% of patients presenting with osteoarthritis and associated rotator cuff arthroplasty have bone erosion that must undergo reconstruction in order to achieve successful shoulder arthroplasty. For those with a lesser degree of bone loss or correction, an augmented baseplate can provide benefits such as reduced bone removal, preservation of cortical bone, and lateralization. An augmented baseplate also provides a simple, reproducible method to restore the glenoid during future reconstruction by reverse shoulder arthroplasty.
