ANS:
Avascular necrosis of the radial head is the result of a series of steps: (1) repeated valgus stress to the elbow joint; (2) stretching of the medial collateral ligament; (3) excessive compression of the radial head against the capitulum, resulting in cartilage deterioration; and (4) compression and reduction of the vascular supply of the head of the radius, resulting in bone death.
