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 the bone's eventual collapse.
A broken bone or dislocated joint can interrupt the blood flow to a section of bone. Avascular necrosis is also associated with long-term use of high-dose steroid medications and excessive alcohol intake.
Anyone can be affected, but the condition is most common in people between the ages of 30 and 50.
Many people have no symptoms in the early stages of avascular necrosis. As the condition worsens, the affected joint might hurt only when we put weight on it. Eventually, their might feel the pain even when we lying down.
Pain can be mild or severe and usually develops gradually. Pain associated with avascular necrosis of the hip might center on the groin, thigh or buttock. Besides the hip, the areas likely to be affected are the shoulder, knee, hand and foot.
Some people develop avascular necrosis on both sides (bilaterally) — such as in both hips or in both knees.
Avascular necrosis occurs when blood flow to a bone is interrupted or reduced. Reduced blood supply can be caused by:
Syphilinum : Very helpful in treating bone necrosis.Useful for bone pains that worsen at night and experienced throughout the night. There is specific pattern regarding the appearance and disappearance of pains. There is gradual increase in bone pains and in the same way, a gradual disappearance of pains. Useful when there is worsening of pains because of heat and some relief by applying cold water. There is great Craving for alcoholic stimulants and a history of excessive alcoholism may be present.
Silicea : Very useful for necrosis (premature death of cells) of a variety of bones ranging from long to small bones. Recommended for necrosis of jaw, wrist bones, hand bones, feet bones, ankle, knees and in addition long bones —including humerus (bone in the upper arm), femur (bone in the thigh) and tibia (bone in front of leg) — are all the site of action for using Silicea. There is sensitivity to cold air when bone pains worsen from a slight exposure to cold air. Warmth brings relief. There is an excessive offensive odor on the feet.
Fluoric Acid : Useful for the necrosis of long bones. The bones include humerus (bone in the upper arm), femur (bone in the thigh) and tibia (bone in front of the leg).Useful to halt the necrosis appearing in long bones. There is excess body heat and the external heat worsens the condition.
Aurum Metallicum : Useful for necrosis in nasal and palatine bones. Useful when pain aggravate at night and may suffer from extremely offensive odor from the mouth and nose along with pain. Useful when patient may feel depressed with a high degree of sadness.
Natrum Sulph : Very useful in AVN of the hip joint. Useful for pain get worse during motion or when stooping,e.t.c
