A periacetabular osteotomy (PAO) is a type of surgery used to treat developmental dysplasia of the hip (DDH), also known as hip or acetabular dysplasia. During a PAO, the surgeon makes a series of cuts around the hip socket and repositions the joint into a more mechanically appropriate position. Some muscles around the hip are temporarily moved during the procedure in order to safely make the cuts, and they are reattached at the end of the surgery. The hip joint may be opened in order to treat torn or damaged tissue and improve the roundness of the upper femur. The bone is held together with screws. A PAO is sometimes called a Ganz osteotomy, named after the professor who developed the procedure.
If your child’s hip dysplasia isn’t treated, it can lead to issues and pain when the labrum and cartilage, which protect the hip joints, start to wear down. When these tissues wear down, the bones rub together and can cause pain and issues with movement. Hip dysplasia is one of the most common causes of hip pain and arthritis in patients younger than 50 years old.
While the idea of your child going into the hospital for surgery can be scary, sometimes it can be beneficial to treat your child’s hip dysplasia and avoid more significant complications as she grows up.
- Helps reduce joint stress and improve hip function.
- Is for children or teens with developmental dysplasia of the hip who are near or have reached the end of skeletal growth.
- May help delay or eliminate the need for total hip replacement later in life. Your child’s doctor will perform tests and imaging studies to help you determine if this procedure is right for your child.
If your child’s doctor has recommended your child undergo PAO surgery to help his hip dysplasia, it’s helpful to know what to expect before, during and after the procedure, as well as what recovery in the hospital, recovery at home and physical therapy may entail.
Improving movement, strength, coordination and balance after surgery
Physical therapy is important to the recovery process and helps patients regain movement before or after surgery. It also helps teach weight-bearing restrictions, strengthens hip muscles and aids in the recovery process after surgery.Learn More
