AO Technical Commission

The AO Technical Commission sits at the heart of the AO Innovation Translation Center (AO ITC) covering Innovation Clearing and Clinical Expertise for our four specialties: trauma, spine, craniomaxillofacial, and veterinary surgery.

Medical-technical committees are responsible for the development and clinical testing of new devices and for supporting their educational concepts. Around 120 outstanding surgeons across the world work together with engineers to solve the most pressing clinical problems.

How we work

The AO Technical Commission consists of three specialty AO technical commissions (Trauma, Spine, and CMF), various Global Expert Committees, Expert Groups, and Task Forces which are convened to provide expert opinion in their respective specialist areas. In a collaborative approach, these committees include representation from the AO's trusted partner DePuy Synthes, a Johnson&Johnson Group Company, or other industrial partners, and may involve colleagues from other AO institutes when needed. The AO Technical Commission plays a crucial role in quality control and product development, forming an essential link between the AO's clinical divisions, clinical units, other institutes, initiatives, and the AO's global network.

Governance


The AO Technical Commission Executive Board (AO TCEB) supervises and steers activities within the AO Technical Commission and ensures that the priorities are in line with the AO’s mission.
