Dr. Theodore Blaine debuts Catalyst OrthoScience's new shoulder system


Theodore Blaine, MD, performed the first cases with Catalyst OrthoScience's Catalyst Stemmed CSR TSA system for shoulder replacement, the medtech company said May 25.

The system, which can convert for reverse shoulder replacement, recieved FDA 510(k) clearance earlier in 2023, according to a news release. 

"The Catalyst Stemmed CSR TSA is the first fully convertible system to feature an anatomical ellipsoid humeral head," Dr. Blaine said in the release. "This is an important distinction because the ellipsoid head allows for more accurate restoration of the natural joint kinematics compared to spherical head designs."
