What could happen to blood vessel of a bone in a bone injury?

Its damaged. When a broken bone displaces, the blood vessels are interrupted. Like bone, vessels will heal over time. Until they do the area of bone supplied by a vessel is without blood. If that is the only vessel to that part of the bone, the bone can die and collapse. This is called avascular, or aseptic, necrosis. Its most common with fractures of the scaphoid in the wrist or head of the femur in the hip.
Bone injury. If the bone injury involves a fracture that displaces (out of place), then the blood vessel within the bone is disrupted/torn. Generally, the blood vessel can reconstitute itself or be bypassed by new vascularization as the bone heals.
