Periacetabular Osteotomy (PAO): Hip Surgery

Reinhold Ganz popularized Periacetabular osteotomy (PAO) for the treatment of hip dysplasia. Hip dysplasia is a condition where the femur or thigh bone is not connected with the pelvis causing the hip joint to be slightly dislocated. This can result in different leg lengths or limping. This condition can be genetic or a person can be born with it. Though, if detected at birth it can be easily cured as infants have soft bones.

Dr. Niraj Vora, a total hip replacement surgeon, in Mumbai says that it is concerning that the need for POA surgeries is increasing. It is seen that 60% of the patients need to undergo hip replacement surgery within 3 years of hip arthritis showing up.

What is a periacetabular osteotomy?

A periacetabular osteotomy or POA is a surgery performed usually on adults or adolescents suffering from hip dysplasia. It is a hip preservation surgery performed by a hip preservation orthopedic surgeon by making cuts on the bone around the hip socket in order to rotate the socket to the right position. Once fixed, metal screws are used to ensure that the bone remains unmoved.

This provides better coverage to the hip socket and thus reduces the stress on the hip socket rim (the cause of cartilage damage). In case of a labral tear i.e., a tear in the cartilage encasing the hip joint, hip arthroscopy is performed along with the POA to repair the tear.

Dr. Niraj Vora, one of the specialists in hip arthroscopy in Mumbai, believes that combining arthroscopy and POA helps inspect the hip joint and can even be used before osteotomy for the treatment of hip pathology.

How do I ensure a speedy recovery?

Physical therapy helps a patient recover proper movement in their bones after the surgery. It begins with basic motion exercises that help improve rotation and stretches the muscles around the hip bone. The therapist assists the patients to walk through parallel bars, followed by crutches which help in restoring previous activity levels and develop confidence in the patient.

The patient can start outpatient physical therapy one month after the surgery. Crutches play a crucial role in the first weeks of recovery as they are important to maintain balance and reduce too much pressure on the operated area. Once completely healed, patients are able to return to their previous level of activity.

Approaching a POA

Before approaching a POA the patients need to go through a physical examination and need to submit their medical history to avoid any complications. For the confirmation of hip dysplasia, orthopedists use X-rays, MRI, and in some cases 3 – D CT scans. These scans provide a clear image of the hip joint and help pinpoint any damages present.
