Video Transcription

Video Summary

The speaker addresses challenges in treating young, active patients with shoulder issues, particularly those with B2 glenoids—a common and difficult-to-treat condition. Traditional total shoulder arthroplasty often fails due to complications like glenoid loosening and soft tissue problems, leading to the rise of reverse total shoulder replacements, which aren’t ideal for younger patients. The speaker advocates revisiting and advancing hemiarthroplasty techniques, emphasizing the use of aspherical humeral head implants that better replicate natural anatomy and reduce stress on the glenoid. Additionally, they promote inlay glenoid implants that preserve bone and decrease loosening risk by avoiding rocking forces common in onlay designs. This “ream and fill” approach conserves native anatomy without correcting glenoid version, yielding promising medium-term outcomes, including improved function and motion comparable or superior to standard implants. Cases of highly active individuals returning to sports support this innovative and bone-preserving method as a potential new standard for these challenging patients.
