Three factors contribute to venous thrombus formation: (1)loss of integrity of the vessel wall (e.g.,injury),(2)abnormalities of blood flow (e.g.,slow blood flow in calf veins associated with bed rest),and (3)alterations in blood constituents (e.g.,a change in clotting factors or increased platelet activity).These three factors are referred to as Virchow's triad.Disuse,atrophy,and shortening of muscle fibers and surrounding joint tissues cause joint contracture,not deep vein thrombosis.
