Hip AVN Treatment Guide: Medications, Surgery and Preventive Care

 

Hip avascular necrosis, or AVN, refers to the loss of bone tissue due to poor blood supply. It usually affects the end part of long bones, causing them to crumble by forming small cracks. They can affect not only long bones but also any bones in your body. Under this condition, a fractured joint or cracked bone can disrupt the blood flow of a particular portion of the bone. 


AVN is also called osteonecrosis, and it mostly affects those between the ages of 30 and 50 years. Individuals taking high-dose steroid medicines for a long time and consuming excessive alcohol are more likely to develop conditions like hip avascular necrosis.

How to Treat Hip Avascular Necrosis?


The treatment procedure for hip avascular necrosis depends completely on the patient's health condition, age, symptoms, femoral head condition, etc. Here are some of the effective treatment methods for hip AVN:


1.Non-surgical Treatment


Individuals in the early stage of avascular necrosis can follow non-surgical treatment. It can relieve the symptoms of AVN but cannot stop its development. Some of the non-surgical treatments are as follows:


●  NSAIDs (nonsteroidal anti-inflammatory drugs) for pain relief
●  Physical therapy to strengthen hip muscles
●  Using crutches, canes, and walkers so that the excessive weight is not put upon the injured hip
●  Proper rest


2.HBO (Hyperbaric oxygen) Therapy


It is another non-surgical therapy that helps tackle the early signs of AVN. It is a safe and effective therapy session that lasts for 90 minutes. An individual needs a minimum of 30 sessions, with five sessions per week. 


3.Bone Grafting


In this procedure, healthy bone tissue is collected from the patient’s body to replace the damaged bone. It can also be done using artificial bone substitutes.


4.Osteotomy


In this method, the surgeon cuts and repositions the femur to transfer the patient's weight to the healthy area of bone that can bear weight.


5.Core Decompression


It is a minimally invasive procedure in which the AVN-affected femoral head is drilled to improve blood flow, reduce the pressure inside your bone, and restore hip joint function.


6.Total Hip Replacement


In case of extreme damage to the femoral head, acetabulum, and hip joint, the patient must undergo a total replacement of their hip.


7.Surgical Intervention


Surgery helps reduce the symptoms of AVN, slow down its progression, and normalize the function of hip joints.


What Causes Hip Avascular Necrosis?


When bone tissues become inactive due to interrupted blood supply to the femoral head, it causes hip avascular necrosis. Its types and causes are discussed below:


1.Nontraumatic Hip AVN 


Excessive intake of alcohol and long-term use of corticosteroids causes almost 80% of nontraumatic AVN. 


2.Traumatic Hip AVN


If the blood flow to your femoral head stops due to trauma, it can cause traumatic hip AVN. It may occur after hip dislocation, fracture, or previous surgery.


Here are some more factors that cause hip avascular necrosis:


●  SLE (systemic lupus erythematosus)
●  Smoking
●  Previous history of chemotherapy or radiation therapy
●  Sickle cell disease
●  Decompression sickness
●  Pancreatitis
●  Gaucher disease
●  Chronic liver disease
●  HIV infection
●  Excessively high lipid levels in blood (hyperlipidemia)
●  Thrombophilia or other blood clotting disorders
●  COVID-19
●  Gout


Note: In most cases, the cause of hip AVN remains unknown.


What are the Symptoms of Hip Avascular Necrosis?


Avascular necrosis (AVN) of the hip usually starts with minor symptoms before getting worse over time. Here are some of the common symptoms:


●  Hip Pain


It is the first and most typical symptom that causes a throbbing ache in the buttocks or groin. As AVN worsens, it gets harder to stand or bear weight on the afflicted side because hip movement becomes more uncomfortable. Early stages may even be symptom-free, and progression times range from a few months to more than a year.


●  Stiffness


As the illness worsens, stiffness and a decreased range of motion may accompany the pain, which may become constant and limit day-to-day activities. 


●  Deformity


Deformity and trouble walking may result from swelling and joint instability, particularly if the bone collapses. When moving the joint, some people get crepitus, which is a grating or cracking sensation. Since timely treatment can enhance results and slow the progression of the disease, early detection is essential.


How to Diagnose Hip Avascular Necrosis?


Here are the diagnostic procedures for avascular necrosis of the hip:


●  Physical Test


During a physical exam for avascular necrosis, a healthcare provider checks for tenderness by pressing around the joints and moving them through various positions to assess any loss of motion. 


●  Imaging Test


As joint pain may occur for several reasons, imaging tests are used to identify avascular necrosis specifically. X-rays may show bone changes in later stages but often appear normal during the early stage of the disorder. 


MRI and CT scans provide more detailed images and can detect early bone changes before they are visible on X-rays. A bone scan involves injecting a small amount of radioactive material, which highlights injured or healing bone areas as bright spots on the scan.
Recovery from hip avascular necrosis is only possible with proper surgical intervention. Considering the complexity of AVN, the cost of surgery may be high. In such situations, a health insurance policy can cover your expenses, providing financial security.
