Avascular necrosis of the hip is a condition characterized by the death of bone tissue in the hip joint due to an inadequate blood supply. This insufficient blood flow can result in tiny breaks in the bone and, ultimately, the collapse of the bone, leading to pain if not treated. Dr. Bedikian, serving patients in Palos Hills and Mokena, is dedicated to addressing your orthopedic concerns, such as avascular necrosis, with expertise and compassion.
Understanding Avascular Necrosis
Avascular necrosis of the hip can occur when the blood flow to a bone is reduced or blocked, either temporarily or permanently. Common causes of reduced blood flow to a bone include injury to the bone or joint, radiation therapy, and conditions that increase pressure inside the bone, such as sickle cell anemia.
Avascular Necrosis Causes and Risk Factors
Avascular necrosis may result from an underlying disease or significant trauma, such as a fracture or dislocation, which impacts the blood flow to the bone. Additionally, avascular necrosis can develop even in the absence of trauma or disease, meaning the exact cause is not understood. However, it is important for patients to be aware of the factors surrounding this condition that elevate the likelihood of its development. They include:
- Fractures in the femoral neck
- Hip dislocation
- Undergoing radiation therapy
- Extended or repetitive use of steroid medications
- Decompression sickness
- Sickle cell disease
- Gaucher's disease
- Excessive alcohol consumption
- Systemic lupus erythematosus (SLE)
- Kidney transplantation
Symptoms
Avascular necrosis often develops slowly, with the earliest symptoms often being associated with other, less serious health conditions. Common symptoms of avascular necrosis of the hip include:
- Pain in the groin area
- Pain in the buttock or thigh area
- Limping and inability to bear weight without significant pain
Diagnosing Avascular Necrosis
Diagnosing avascular necrosis involves Dr. Bedikian conducting a detailed assessment of your symptoms and medical history, in addition to a physical exam to check the joint's range of motion and response to pressure. X-rays, CT scans, radioisotope bone scans, and MRI scans may also be necessary to get a better understanding of the condition.
Exploring Treatment Options
The treatment of avascular necrosis is dependent on the stage of the disease and the patient's lifestyle. Dr. Bedikian works with each patient to develop a tailored treatment plan consisting of the most appropriate options that encourage full recovery from this injury. Nonsurgical and surgical treatment options may include:
Nonsurgical: Conservative measures such as the use of nonsteroidal anti-inflammatory drugs (NSAIDs) and non-weight-bearing exercises can help slow the progression of this condition.
Surgical: Many patients need surgery to address avascular necrosis. Surgical interventions include bone grafts, decompression of the inside of the bone, realignment of the bone, and hip replacement.
Can I Prevent Avascular Necrosis of the Hip?
To reduce the risk of developing avascular necrosis of the hip, it is best to avoid injuries to the hip, such as bone fractures and joint dislocation. If you take certain medications, such as high-dose steroids, you may also benefit from a reduction in your dosage, as steroid use is associated with bone damage. You should also take measures to avoid decompression disease when diving underwater.
