What is osteonecrosis

First of all, osteonecrosis is one of the diseases, and the so-called osteonecrosis of osteonecrosis refers to the necrosis of human bone tissue components. In traditional Chinese medicine, osteonecrosis is called osteoerosion. Many parts of the human body will cause osteonecrosis. There are many reasons for osteonecrosis. In clinical practice, osteonecrosis of the femoral head is the most common. Most of them focus on introducing the causes, symptoms, treatment, exercise and prevention of osteonecrosis of the femoral head. For osteonecrosis, it can occur in any part of the human body. Only more than 40 cases of ischemic necrosis have been found, and the incidence of femoral head necrosis is the highest, which is mainly determined by the characteristics of biomechanics and anatomy. Because the femoral head is a terminal vessel with 20-25 branches in fan shape, it forms an arteriovenous ring at the junction of head and neck, which originates from the internal and external circumflex femoral arteries.

Secondly, the onset of avascular necrosis of the femoral head is slow, the course of disease is long, and the patient has no obvious symptoms for a long time. The most common clinical symptoms were hip discomfort or pain. The pain was obvious after fatigue or long walking, and relieved after rest. In the course of femoral head necrosis, lumbosacral or knee joint pain often occurs, which is easy to be misdiagnosed as lumbar disc prolapse, spinal stenosis, sciatica, rheumatoid arthritis, synovitis, etc.

Finally, the most prominent feature of this disease is that the degree of conscious symptoms is not proportional to the degree of necrosis and destruction of the femoral head. With the aggravation of lameness and pain, the function of hip joint is gradually limited, and the hip joint can be stiff and disabled in the late stage. There are many reasons for getting sick. After getting sick, there will be no feeling at the initial stage. With the development of the disease, there will be pain feeling when long-term weight-bearing, and the condition will be relieved after rest.
