Tulane Ortho Weighs in on “Thermal and Cutting Dynamics of New and Used Glenoid Reamers During Total Shoulder Arthroplasty"

Tulane Orthopaedic physicians Drs. Bill Sherman, Michael O’Brien, and Buddy Savoie presented a new journal study which analyzed glenoid loosening during Total Shoulder Arthroplasty.

Glenoid loosening is the most common complication of Total Shoulder Arthroplasty (TSA) resulting in revision. Inaccurate reaming and thermal osteonecrosis from heat generated during the reaming process may contribute to TSA failure by creating a suboptimal bone-implant interface for osteointegration. This biomechanical study investigated the differences in depth penetration and heat generation of used community glenoid reamers in comparison to brand new reamers by using a clinically relevant force.
