Cohen, MD, an orthopedic surgeon at Adena Health System in
Chillicothe, Ohio. In June, he implanted the first Univers Revers following its FDA approval for the U.S. market back in the spring.
Three advances in the implant's technology and design "make a big
difference," says Dr. Cohen, who had provided Arthrex engineers with
suggestions for improvement while it was in development.
1. The human angle. The humeral component can be implanted with
its neck angled at either 135 degrees or 155 degrees. The former is
said to deliver more stability, while the latter offers a greater range of
motion. "As with all medical solutions, there's a debate in the community as to which provides the better outcome," he says. "So this
implant offers both options."
2. Differences and durability. The implant's design lets the humeral
component's cup be seated in accordance with each patient's differing
anatomy: either directly central, or with a posterior offset. This
option, which is not possible with all shoulder implants, enables a
"press fit procedure," in which the body heals to the humeral component for a more durable bond than cementing the implant.
3. One size doesn't fit all. Differently sized patients have differently
sized anatomies. The Univers Revers offers a range of sizes. Its glenoid component is available with base plates in small, medium and
large, and with ball diameters of 36mm, 39mm or 42mm.
Dr. Cohen has done plenty of reverse shoulder replacements in his
career, but he says the variations that the new implant offers surgeons
can help them deliver humeral reconstruction appropriate to each
patient's anatomy, and a better match can mean better outcomes.
