Postraumatic Arthrosis is a premature form of DJD which results from a severe trauma. Typically, results from a fracture into the ball and socket hip joint or from previous dislocations of the hip joint that can cause accelerated damage to the cartilage surface of the ball and socket joints.
Avascular Necrosis (AVN), is a condition that affects the ball portion of the hip joint when there is a lack of blood flow to the bone. Lack of blood flow can cause the bone to die which can cause severe pain and even lead to collapse of the ball portion of the hip joint.
