The periacetabular osteotomy (PAO) is a surgical procedure to correct a structural
deficiency of the hip socket, where the femoral head (ball) is incompletely covered by the congenitally-shallow acetabulum (socket). Several bone cuts (osteotomies) are performed around the acetabulum and it is redirected into an optimal position so that the femoral head is
adequately covered. The osteotomy is then stabilized with screws. This surgery is performed by only a few surgeons due to its complexity and steep learning curve. The traditional technique used by most is known as the ‘Ganz’ and it carries few significant drawbacks, especially in less experienced hands. Dr. Mei-Dan developed the CU PAO, utilized now by surgeons all around the world, and which enables faster recovery and rehabilitation.
