Shoulder Surgeons Perform First U.S. Surgeries Using Exactech’s Next Generation Cage Glenoid
UF Startup Exactech, a developer and producer of innovative implants, instrumentation, and smart technologies for joint replacement surgery, announced successful first surgeries using the Equinoxe® Laser Cage Glenoid, an innovative, next-generation shoulder implant designed to improve glenoid fixation in anatomic total shoulder arthroplasty.
This new glenoid implant, available in standard and augmented options, features a central bone cage and three peripheral cage pegs. Each cage peg is titanium, porous and 3D-printed. First surgeries were performed by Bradley Schoch, MD, of the Mayo Clinic (Jacksonville, Fla.), and Sean Grey, MD, of the Orthopaedic & Spine Center of the Rockies (Fort Collins, Colo.) – two of the product’s design surgeons.
Exactech’s manufacturing process for the Laser Cage Glenoid is unique. Its 3D-printed cage pegs are directly molded to the backside of the ultra-high molecular weight polyethylene (UHMWPE) articular surface, so there is no mechanical locking mechanism. Preclinical testing demonstrated the device successfully withstood cyclic loading at 3,750N (~850lbs) when implanted 5mm proud (simulating a glenoid that is not fully seated) – an extreme loading magnitude and configuration relative to industry standards.
