How is ache inside crus bone to return a responsibility

First, extraosseous factors: vascular rupture and compression of the femoral head caused by trauma, vasculitis, vascular obstruction caused by arteriosclerosis, Raynaud's disease, decompression sickness and vasospasm caused by sympathetic reflex can directly or indirectly lead to avascular necrosis of the femoral head.

The second: bone factors: abnormal red blood cells in hemoglobinopathy, nitrogen embolus in decompression sickness, fat embolus in alcoholism and pancreatic diseases can block the bone microvessels, leading to avascular necrosis of the femoral head. In addition, the abnormal accumulation of red blood cells in Gaucher's disease, metastasis of tumor, hypertrophy caused by hormone, and the increase of the volume of bone marrow content caused by fat cells can lead to the increase of pressure in the bone marrow cavity, compression of bone microvessels or bone pressure, and increase the resistance of blood flow, thus further leading to ischemia, cell degeneration and necrosis, edema, etc.

Third: the tissue edema has increased, and the intraosseous pressure has further increased, forming a series of vicious circle, especially the limb continues to load, increasing the pressure of ischemic femoral head, which will accelerate the necrosis of bone and lead to the fracture of trabecula and collapse of femoral head.
