Do you suffer from persistent hip pain that seems to worsen over time? Have you been diagnosed with avascular necrosis of the hip and are concerned about treatment options? This progressive disease causes bone tissue to die. This occurs due to a lack of blood supply, which can lead to the collapse of the femoral head and deformation of the hip joint.
Treatment of hip avascular necrosis aims to reduce pain and slow down bone damage. It also seeks to improve lost function. Most people with this condition need hip surgery. But the appropriate treatment depends on several factors, such as the stage of necrosis, age, and the patient’s health status.
Diagnosing Avascular Necrosis of the Hip
To diagnose avascular necrosis of the hip, several methods are used. First, a physical exam is done and symptoms are evaluated. Imaging tests are then done. The doctor looks for information about past health and examines the hip to see for bone damage.
Physical exam and symptom assessment
In the physical exam, the doctor applies pressure to the hip joints. This helps find sensitive areas. It also moves the joint to see if there is less mobility. Symptoms of this disease include pain in the groin, thigh, or buttocks.
- Pain in the groin, thigh, or buttocks
- Pain that worsens with physical activity
- Pain that radiates to the knee
- Lameness or difficulty walking
- Stiffness in the hip
Imaging tests: X-rays, MRI, and CT scan
Imaging tests are key to diagnosing avascular necrosis of the hip. They help find the source of the pain and identify changes in the bone. The most commonly used tests are:
- X-rays: They show changes in the shape and density of the bone.
- Magnetic resonance imaging (MRI): Detects early changes in the bone.
- Computed tomography (CT) scan: This gives detailed pictures of the bone.
Bone scan to detect lesions
A bone scan is another tool for diagnosing this disease. A radioactive tracer is used and injected into a vein. Then, you see where it is going and identify the lesions.
| Diagnostic | Advantages | Disadvantages |
|---|---|---|
| Radiographs | Affordable and widely available | May not detect early changes |
| MRI | Very sensitive to detect early | Expensive and may require more time |
| CT scan | Provides detailed images of the bone | Exposes the patient to radiation |
| Bone | Helps identify the location and extent of lesions | Requires injection of a radioactive tracer |
In conclusion, the diagnosis of avascular necrosis of the hip combines physical examination, symptom evaluation, and imaging tests. These tools allow doctors to accurately determine the disease. They can then create an appropriate treatment plan for each patient.
Nonsurgical Treatment of Avascular Necrosis of the Hip
In the early stages of avascular necrosis of the hip, nonsurgical treatment is a good option. It helps relieve pain and delay illness. This approach focuses on managing pain, maintaining mobility, and reducing pressure on the joint.
Nonsteroidal anti-inflammatory drugs (NSAIDs) to relieve pain
NSAIDs, such as ibuprofen and naproxen, are the first choice for pain from avascular necrosis of the hip. They reduce inflammation and relieve pain. In addition, painkillers and muscle relaxants can be used to improve quality of life.
Physical therapy and exercises to maintain joint mobility
Physical therapy is key in non-surgical treatment. A physical therapist can create an exercise program to maintain mobility and strengthen muscles. Recommended exercises include:
- Range-of-motion exercises to maintain hip flexibility
- Strengthening exercises for the hip and lower back muscles
- Gentle stretches to prevent joint stiffness
- Low-impact exercises , such as swimming or stationary cycling, to maintain fitness without putting stress on the joint
Lifestyle modifications and reduced load on the affected joint
In addition to medication and physical therapy, changing your lifestyle is crucial. Some recommendations include:
- Avoid high-impact activities, such as running or jumping, that can increase pressure on the damaged joint
- Maintaining a healthy weight to reduce the load on the affected hip
- Use assistive devices, such as a cane or crutches, to lessen the load on the joint when walking
- Alternate rest periods with low-impact physical activity to avoid fatigue and joint overload
It is important to monitor patients with avascular necrosis of the hip. If symptoms persist or worsen, surgical options may be necessary.
Surgical treatment of avascular necrosis of the hip
If conservative treatment doesn’t work, it’s time to think about operations. These operations can relieve pain and help your hip continue to function well. What is done depends on how advanced the disease is and the patient’s state of health.
Decompression of the core to relieve pressure and stimulate the formation of new bone tissue
Core decompression is an operation that removes a small part of the damaged bone. This reduces pressure and helps the bone heal. It is done in the early stages of the disease to relieve pain and promote regeneration.
This operation is sometimes combined with bone grafts or growth factors. This helps the bone heal better.
Bone grafting to strengthen the affected area
A bone graft is when healthy bone is put into the damaged site. This bone can be from another part of the body or from a donor. The goal is to make the damaged bone stronger and integrate with the surrounding tissue.
This procedure can be done with other operations to improve long-term results.
Osteotomy to redistribute the weight of damaged bone
Osteotomy is when the bone is cut and moved to change the load. This is done in patients with moderate avascular necrosis. The goal is to relieve pain, improve hip function, and delay the need for hip replacement.
This operation can be done on the femur or acetabulum, depending on where the lesion is.
Full or partial hip joint replacement
If the disease is very advanced, sometimes all or part of the hip needs to be replaced. This is done with components made of metal, ceramic or polyethylene. This procedure is a major operation that requires recovery time, but it can relieve pain and improve hip function.
| Operation | Directions | Proceeds |
|---|---|---|
| Core decompression | Early stages of avascular | Pain relief, stimulation of revascularization and formation of new bone tissue |
| Bone grafting | Intermediate stages of avascular | Strengthening damaged bone, promoting graft integration |
| Osteotomy | Intermediate stages of avascular | Load redistribution, pain relief, improved joint function, delayed total hip replacement |
| Full or partial hip | Advanced stages of avascular | Pain relief, restoration of joint function |
Choosing the right surgical treatment depends on many factors. This includes the status of the disease, the patient’s age and health, and what the patient hopes to achieve. It’s important to work with your medical team to make a well-informed decision and create a treatment plan that works best in the long run.
Treatment of Avascular Necrosis of the Hip with Regenerative Medicine
Regenerative medicine is a promising option for treating avascular necrosis of the hip. It is based on the use of stem cells from the patient’s bone marrow, fat cells, or blood. The goal is to stimulate the growth of new bone tissue in damaged areas.
Aspiration and concentration of bone marrow to stimulate the growth of new bone tissue
The bone marrow aspiration and concentration procedure is minimally invasive. It is performed early in avascular necrosis of the hip. Necrotic bone is removed and replaced with stem cells from the patient’s bone marrow. These cells can develop into bone cells and help regenerate damaged tissue.
Patients can go home the same day of treatment. It is important to bear partial weight for 4-6 weeks. A follow-up is also done every 6 months to see how the disease progresses.

Studies show benefits of stem cell therapies in bone regeneration. Regenerative medicine, together with central decompression and stem cells, promises good results in osteonecrosis of the femoral head, especially at the beginning.
Recovery and Rehabilitation After Treatment of Avascular Necrosis of the Hip
Recovery and rehabilitation after treating avascular necrosis of the hip are key. They help to regain strength and movement of the hip. Physiotherapy is essential in this process.
A good rehabilitation program includes early mobilization and strengthening exercises. It also includes range-of-motion exercises and manual therapy. These help you recover optimally.
In recovery, assistive devices such as walkers or crutches are sometimes needed. These devices offer support and reduce the load on the joint. It is important to follow the instructions of the physiotherapist to avoid complications.
Recovery time after hip replacement surgery ranges from 3 to 6 months. This depends on age, overall health, and previous damage. It is key to be patient and follow a personalized treatment plan.
Avascular necrosis of the hip affects 15 to 20 people per 100,000 per year. Prosthesis surgery has risks such as infection or chronic pain. But, good recovery and rehabilitation can minimize these risks.
