Periacetabular Osteotomy
Periacetabula Osetotomy or PAO surgery is used for correcting acetabular dysplasia or hip dysplasia. Hip dysplasia refers to a condition where there is insufficient coverage of the hip socket ball (femoral head) because of a shallow hip socket (acetabulum).
The acetabulum, during PAO, gets repositioned to cover the femoral head properly. This helps in improving the hip joint stability. PAO surgery decreases hip pain, improves hip function and stops further damage inside the joint, which may lead to hip arthritis.
Board certified orthopedic surgeon Dr. Tigran Garabekyan provides hip surgery to patients in Los Angeles, Century City, CA, and surrounding locations.
Surgical Procedure
PAO may be considered for patients with mild hip dysplasia that have not yet reached skeletal maturity. They should also suffer from acetabulum malalignment but not advanced osteoarthritis. PAO is popularly recommended for patients with milder forms of hip dysplasia. This is especially true when other surgeries, such as a hip arthroscopy have failed.
Hip arthroscopy is useful in repairing the labrum. However, it doesn’t correct dysplasia. Your surgeon will take into account your lifestyle and age while deciding to proceed with a PAO surgery. You should also discuss your individual expectations and goals.
The surgeon, during a periacetabular osteotomy, will make a series of cuts on the bone to reposition your acetabulum within the pelvis. This will be done for restoring your anatomy to a more normal position. Your bones will then have screws for stabilizing the position. New bone will form during the healing process across the cuts made to secure the acetabulum within the pelvis. This will help establish a proper alignment of the hip socket and ball joint.
Femoral osteotomy is necessary for correcting malalignment of the femur in almost 10% patients. This is the case with the neck and head of the femur. In select patients, PAO may be performed along with hip arthroscopy. For instance, the surgery may be performed for repairing a damaged labrum.
X-ray guidance will be used throughout the surgery. Muscles and nerves supporting and surrounding the hip joint will be carefully protected.
Recovery and Results
Patients undergoing PAO may require hospitalization for 2 – 4 days. Instructions and physical therapy will be provided to you in addition to weight-bearing guidelines. You may need to use crutches for 6 – 8 weeks. Most patients can return to their work or school after three months for resuming athletics after 6 – 12 weeks. Surgery in the case of dysplasia that affects both hips will be performed 4 – 6 months apart.
PAO yields great results in patients that are ideal candidates and have not yet developed significant hip joint arthritis. This is true even after 20 – 25 years post-surgery. PAO when performed by a skilled orthopedic surgeon is safe and results in predictable outcomes. You should get the surgery performed by an experienced surgeon at a center that deals with a lot of hip patients.
