Zimmer Biomet Holdings, Inc., based in Warsaw, Indiana, has announced that the first surgical case utilizing its Comprehensive Augmented Baseplate was performed by John W. Sperling, M.D., an orthopedic surgeon at Mayo Clinic.
First Case for Augmented Shoulder Baseplate

According to the company, “This newly cleared baseplate boasts a simplified circular design at three augment heights (3mm, 5mm and 7mm buildup), allowing for augment placement in any orientation to accommodate various unique bone anatomies. Its circular design also allows bone ingrowth into the rim of the baseplate for optimal fixation.”
“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 and clinically proven technologies.”
“The system aims to minimize the potential challenges of removing well-fixed humeral stems by allowing conversion to a reverse shoulder using any of the existing Comprehensive stems. Additionally, the Comprehensive Augmented Baseplate leverages Mayo Clinic’s patented methodology for the optimization of shoulder arthroplasty components developed by Dr. Sperling at Mayo Clinic, Rochester, Minn., to provide relevant sizing for a conservative approach to bone removal to preserve bone stock if a future revision procedure is necessary.”
“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.
Asked what it was like to work with the new, simplified circular design, Dr. Sperling told OTW, “The circular design of the augmented baseplate allows the surgeon to address bone deficiency in any orientation on the glenoid face in a simple and efficient way. Having multiple augment thicknesses also allows the surgeon to address a wide spectrum of severe bone deficiencies.”
“Besides addressing glenoid bone deficiencies, the bone-preserving application allows the surgeon to create appropriate tilt with the augmented baseplate rather than remove inferior glenoid bone. This technique allows the surgeon to preserve glenoid bone stock and optimize soft tissue tension by preserving scapular length.”

This is a fascinating development. In my practice we've seen similar outcomes with the revised protocol. The key differentiator seems to be patient selection criteria. Has anyone else noticed the correlation with BMI thresholds?
Great point. I'd push back slightly on the conclusion, the sample size in the cited study is too small to draw population-level inferences. That said, the directional signal is compelling and worth a larger RCT.
We implemented a similar approach last year. Early results are promising but we're still gathering 12-month follow-up data. Happy to share our protocol if anyone is interested.
