Osteotomy is a word used to describe shifting or re-aligning the bones. Osteotomy is the preferred procedure in young adults to correct dysplasia of the hip, as it often allows people to either postpone or avoid hip replacement altogether. There are several types of osteotomies depending on the location or area of bone that is misshapen. At Panorama, we offer osteotomies of the femur, pelvis, or acetabulum to correct problems with the hip joint if necessary.
A commonly used osteotomy to correct dysplasia is the “Ganz” osteotomy (also called a peri-acetabular osteotomy, PAO). This is a procedure in which the cup (acetabulum) is moved into a better position to support the hip joint. This procedure was developed in the early 1980’s in Europe and has evolved over the years to meet the needs of patients with dysplastic hips. The Ganz Osteotomy is designed to alleviate the pain and restore proper function of the hip. First developed in the 1980’s for active people with hip pain from dysplasia, the main purpose of the Ganz Osteotomy is to briefly separate the hip socket from the pelvis and re-align it so that it is properly seated over the ball (femoral head). This correction in position of the cup allows the joint to properly function and alleviates excess pressure on the hip cartilage.
The Ganz Osteotomy can be performed in adolescents and young adults after the growth plate around the hip socket is closed. The procedure itself is done through small cuts in the pelvic bone that allow the surgeon to re-align the hip socket and then hold it in place with 2 – 3 screws until it heals. This can most often be performed through an incision only 3-6 inches in length.
Individuals who are a good candidate for Ganz Osteotomy include:
- Active individuals with hip pain from dysplasia
- Individuals with a round femoral head
- Individuals with minimal pre-existing arthritis
- Non-smokers
- Physically fit patients (with BMI of less than 30)
The goal of a Ganz Osteotomy is to:
- Restore the proper shape to the hip joint
- Reduce pain in the hip joint
- Prolong the life of the hip joint
- Delay or eliminate the need for a hip replacement in the future
- Allow patients to return to full athletic and daily function.
