AVN Hip joint

Avascular necrosis is the death of bone tissue due to a lack of blood supply. Also called osteonecrosis, it can lead to tiny breaks in the bone and cause the bone to collapse. The process usually takes months to years.


A broken bone or dislocated joint can stop the blood flow to a section of bone. Avascular necrosis is also associated with long-term use of high-dose steroid medications and too much alcohol.


 Reduced blood supply can be caused by:

  1. Joint or bone trauma. 
  2. Fatty deposits in blood vessels. 
  3. Some Medical conditions, such as sickle cell anemia and Gaucher’s disease



Risk Factors –

  1. Trauma
  2. Steroid use
  3. Drinking too much alcohol
  4. Bisphosphonate use
  5. Radiation therapy for cancer can weaken bone. Organ transplants, especially kidney transplants.
  6. Pancreatitis, Gaucher’s disease
  8. Systemic lupus erythematosus
  9. Sickle cell anemia
  10. divers’ disease or the bends
  11. Certain types of cancer, such as leukemia


Treatment –

The goal is to prevent further bone loss.



In the early stages of avascular necrosis.


Nonsteroidal anti-inflammatory drugs (NSAIDs). 

Osteoporosis drugs. 

Cholesterol-lowering drugs. 

Medications that open blood vessels. 

Blood thinners


Intervention –

PRP ( Platelet Rich Plasma) 

BMAC ( Bone Marrow Aspirate Concentrate) 


Surgery –

Hip Replacement
