Hip Dysplasia Treatment
Developmental dysplasia of the hip (DDH) is a condition where the hip socket (acetabulum) does not adequately cover the head of the femur. This results in an improper distribution of loads in the joint, increasing pressure on the cartilage and causing instability. Over time, this instability can damage the cartilage and other structures surrounding the joint, increasing the risk of developing hip arthritis (coxarthrosis).
Symptoms and Signs
- Hip or groin pain, especially during or after physical activity or walking
- Hip or groin pain, especially during or after physical activity or walking.
- Limping: An uneven gait may develop due to instability or pain in the joint.
- Early development of osteoarthritis in the hip joint.
- Clicking or popping sounds: Audible noises during movement, which may indicate mechanical issues within the joint.
Causes
Hip dysplasia can be caused by various factors, including genetic, environmental, and mechanical influences. Some of these risk factors include:
- Family history of the condition
- Fetal position in the womb, especially if breech
- First pregnancy or a uterus with limited space
- Low levels of amniotic fluid during pregnancy
Our Study on Hip Dysplasia
we have conducted an in-depth study on hip dysplasia to better understand its progression, optimal diagnostic methods, and effective treatment options. Our research focuses on both early detection and tailored management, aiming to improve outcomes for patients at different stages of the condition.
- Periarticular Muscle Strengthening with Emphasis on the Gluteus Medius
- Periacetabular Osteotomy (PAO)
Is There a Solution?
The decision for one treatment over another will depend on various factors. The most fundamental and determining aspect will be the degree of dysplasia. In some cases, this degree can be easily identified through an X-ray, but for moderate cases, additional studies may be necessary. Additionally, the second determining factor will be the level of pain, the intensity of symptoms, and the condition of the joint (with healthy cartilage or early signs of degenerative changes).
Based on this, the main treatment options are:
Innovation and Evolution in Treatment
Unlike previous techniques, which could result in pelvic asymmetries or compromise the mechanical stability of the hip, the Periacetabular Osteotomy (PAO) by Ganz is performed through a single surgical approach, preserving the posterior pelvic column intact. This allowed not only greater precision in correcting dysplasia but also improved functional recovery for patients.
This innovative approach became possible due to the combination of anatomical studies on cadavers and bone models conducted prior to the first clinical interventions. These studies provided a detailed understanding of pelvic biomechanics and optimal surgical access, solidifying PAO as a significant advancement in orthopedic surgery.
Key Advantages of the Technique:
- Preservation of pelvic stability: Maintaining the posterior column prevents structural weaknesses and post-surgical complications.
- Enhanced precision: The single surgical access allows accurate repositioning of the acetabulum to improve femoral head coverage.
- Minimized post-operative complications: Reduced risk of pelvic asymmetry, leading to better weight distribution and long-term joint health.
- Faster functional recovery: Patients experience improved mobility and reduced rehabilitation time compared to older methods.
The combination of innovative surgical design and preclinical research positioned the PAO technique as a game changer in hip dysplasia treatment, offering long-term benefits and improved quality of life for patients.

A 60% Success Rate at 20 Years!
The Periacetabular Osteotomy (PAO) by Ganz, developed in 1988, has proven to be an effective option for treating hip dysplasia while preserving the natural joint. Long-term studies, including 20-year follow-up data, demonstrate a 60% success rate in patients who have not required total hip replacement.
However, several factors can negatively affect long-term outcomes, such as:
- Advanced age at the time of surgery
- Degree of preoperative osteoarthritis
- Presence of symptoms like limping or a positive impingement test
These factors highlight the importance of early diagnosis and timely intervention to maximize the benefits of the procedure and reduce the risk of long-term complications, such as arthritis or the need for joint replacement
