Osteonecrosis
Osteonecrosis is a condition in which bone tissues die due to lack of blood supply. It is a painful condition of the bone that limits one’s physical activity and mostly affects the hip, knees and shoulders.
Causes
Reduced blood supply which leads to osteonecrosis can be caused by factors like:
- Physical trauma such as injury
- Use of corticosteroids
- Excessive alcohol consumption
- Blood disorders such as sickle cell anemia
- Radiation exposure for cancer treatments
- Fat deposits in blood
Symptoms
Pain is the most important symptom of osteonecrosis. There might not be any symptoms in the beginning. A mild pain that develops gradually progresses to severe pain.
