Introduction
Femur or the thigh bone is the strongest bone in the body and head of which supports the major weight of the body. Avascular necrosis (AVN) of femoral head is a condition brought about by the interruption of the blood flow to the head of the femur. This condition will lead to disability and consequent joint destruction requiring hip replacement. Femoral head failure occurs within two years of the development of hip pain, which is initial symptom of the disease.
It commonly affects men in the age of 40 to 60 years. | |
