AO Technical Commission Awards

AO Technical Commission Innovation Prize awarded to the Pelvic Expert Group

The AO Technical Commission is delighted to announce the Pelvic Expert Group (PEEG) as the esteemed winner of the 2023 Innovation Prize. The PEEG has been honored for its innovation in developing the Intrapelvic Acetabular System, a comprehensive set of implants and tools offering innovative solutions in pelvic surgery.

The genesis of this system stems from the careful observation of evolving fracture patterns and a paradigm shift from non-operative to surgical treatment in pelvic fractures. The Intrapelvic Acetabular System addresses the complexities associated with fracture types and recognizes that screw fixation alone may not always suffice. The introduction of a plate applied to the quadrilateral surface proves to be a pivotal advancement.

The AO Technical Commission commends the PEEG’s outstanding contribution to advancing orthopedic care. The Intrapelvic Acetabular System stands as a testament to the group’s commitment to innovation, ultimately improving outcomes for patients undergoing pelvic surgery.


The PEEG is comprised of:

  • Michael Stover (US)—Chairperson
  • Jorge Barla (Argentina)
  • Robin Peter (Switzerland)
  • Ramesh Sen (India)
  • David Stephen (Canada)
