Avascular Necrosis
Avascular means the loss of blood supply,
necrosis means decay. In this condition, the blood supply to the head
of femur (The ball of the ball and socket hip joint) gets reduced. Which
causes the ball to loose its normal smooth and rounded shape. Since the
ball becomes irregular in shape, the friction inside the joint increases,
causing stiffness and pain.
