Comprehensive Note on Avascular Necrosis.

Avascular necrosis is a painful bone condition that worsens over time and can affect mobility. It occurs when something cuts odd blood flow to one of your bones. Causes include broken bones, dislocated hips, radiation therapy and alcohol misuse. Most people need surgery, sometimes joint replacement, to ease pain and improve mobility. 

What is the definition of Avascular necrosis? 

When an obstruction prevents blood flow to your bone tissue, you develop avascular necrosis. Your skeletal system produces new bone tissue to replace aging bone tissue that eventually deteriorates and dies. Thus, your bones are constantly changing. Consider this a cycle in which your body produces new tissue to replenish the deteriorating and dying tissue. This programme must be followed precisely to maintain the strength and health of your bones. The best doctors from the best orthopedic hospitals in India offer you satisfying treatment. 

What are the symptoms of avascular necrosis? 

Avascular necrosis is brought on by diseases that stop blood flow to bone tissues or by fractures in the bone. Twenty percent of cases of avascular necrosis have no apparent cause. Avascular necrosis has the following known causes:

• Traumatic avascular necrosis may arise from a dislocated joint or broken bone.
• Nontraumatic avascular necrosis: It is the result of a disease or other medical condition that obstructs the blood supply to your bone tissue. On both sides of the body, nontraumatic avascular necrosis frequently affects the same bones. For instance, you may have avascular necrosis in your left shoulder if you have it in your right.

A medical condition that can cause avascular necrosis

Some medical conditions or treatments can lead to avascular necrosis:

• Osteoporosis. 
• Blood disorders, such as sickle cell anemia.
• Diabetes.
• Cancer treatments, such as radiation therapy.
• Decompression sickness in scuba divers.
• HIV.
• Lupus.
• Organ transplants.

Symptoms of avascular necrosis

Here are some symptoms that appear over time that could be signs of avascular necrosis:

• Intermittent pain occurs and eases when you put pressure on your bone and then remove the pressure.
• Increasing pain and stiff joints.
• Limited range of motion.
• Limping if you have avascular necrosis in your hips or knees.
• Difficulty climbing stairs, standing or walking.

Treatment plans for the avascular necrosis. 

There are several treatment plans for avascular necrosis. 

Medication

• Anti-inflammatory non-steroidal medications: Over-the-counter drugs such as naproxen, sodium or ibuprofen may lessen avascular necrosis pain.
• Cholesterol-reducing medications: Lower blood fat and cholesterol levels help avoid arterial obstructions that might result in avascular necrosis.
• Thinners of blood: Blood thinners like warfarin may be able to avoid clots in the feeding vessels in cases of clotting problems.

Therapy

• Rest: Restricting physical activity using crutches for several months 
• Exercises: A physical therapist can teach exercises to help maintain or improve the range of motion in the joint.
• Electrical stimulation: Electrical currents might encourage the body to grow new bone to replace the damaged bone. 

Surgeries 

• Core decompression: A surgeon removes part of the inner layer of bone. Besides reducing pain, the extra space inside the bone triggers the production of healthy bone tissue and new blood vessels.
• Bone transplant: This procedure can help strengthen the area of bone affected by avascular necrosis. The graft is a section of healthy bone taken from another body part.
• Bone reshaping: A wedge of bone is removed above or below a weight-bearing joint to help shift weight off the damaged bone. Bone reshaping might help postpone joint replacement.
