The Biomechanics of Metallic Implant Development and Testing

Emmon Johnny Chen, MS

The internal environment of living organisms proves a harsh milieu for manufactured items due to the corrosive ions that break down most materials.

The Biomechanics of Reverse Total Shoulder Prosthesis

Christian M. Schmidt II, MD; Mark A. Frankle, MD, FAAOS

Reverse total shoulder arthroplasty (RTSA) addresses the deltoid’s unopposed force by flipping the articulation with a spherical glenoid and a semi-constrained humeral socket, which converts the action of the deltoid from a destabilizing superiorly directed shear force into a stabilizing rotational force that elevates the arm and stabilizes the articulation.

AAOS and FDA Prioritize Collaboration to Promote Medical Device Safety and Innovation

Ryan Pezold, MA, MBA

AAOS and the FDA both seek to further strengthen their working relationship by encouraging AAOS members who are considering submitting live educational events for the 2025 AAOS Annual Meeting programming to contact representatives from the FDA to discuss their topics and request FDA contributors when a federal regulatory perspective may add to the quality of the content.

Generative AI Could Transform Healthcare

Leah Lawrence

The symposium, titled “Generative Artificial Intelligence—A Technology Set to Transform Musculoskeletal Care?” was an exploration of generative AI and its risks, challenges, and opportunities in the healthcare arena. It included insights from several experts to help attendees navigate these topics.

Distractions in the OR Can Impact Surgical Workflow and Outcomes

Maxwell V. Phillips, MD; Zaid Memon; Alexander Phillips, BS; Ajay Srivastava, MD, FAAOS
