Osteonecrosis of the femoral head within the duration of symptoms

Also known as aseptic necrosis of the femoral head necrosis of the femoral head and avascular necrosis, which is common Clinical Orthopedics and refractory chronic diseases of the femoral head necrosis due to the hip injury, and long-term use of hormone drugs , alcoholism and other reasons, the blood supply of the femoral head caused obstacles, the femoral head is not normal bone tissue nutrition, in the femoral head to the bone cells, bone marrow hematopoietic cells, fat cells necrosis. As necrosis of the bone tissue fragile, and the need to load the hip, so time will be in the femoral head collapse, all the affected hip.
Early symptoms: low back pain, the affected hip pain, the affected groin pain, limb knee pain, limb chills, activities for a long time weakness, pain, fatigue. These symptoms can not at the same time, it was a 12 symptoms or several symptoms disappear after a short period of time, many times. This is the early symptoms of necrosis of the femoral head should be promptly to the hospital for CT, MRI, or ECT, can be found necrosis of the femoral head. X-ray film is not able to early diagnosis. When the X-ray change, the condition has been achieved in the late, late for some. Early necrosis of the femoral head because the X-ray can see around the femoral head to reduce blood circulation, osteoporosis, a small amount of cystic change. Therefore, X-ray generally can not rely on early detection. Nevertheless, at this moment due to increased pressure within the femoral head, limb pain more obvious each part is often misdiagnosed as diseases such as rheumatism Yaochuibing knee, pain treatment, a number of commonly used analgesics or closed therapy, the symptoms disappeared, or that the illness , resulting in misdiagnosis, the development of advanced illness, which delayed the treatment of patients with the best opportunity. Mid-femoral head necrosis, very obvious symptoms, the main line Quinuclidinyl limp excuses? Function occurred obstacles photographed, X films, will see the majority of the trabecular bone loss, cystic changes, bone sclerosis, femoral cartilage fracture collapse. Advanced femoral head necrosis in patients with more severe limp, was obviously short legs, walking difficulties, pain, X-ray to see the femoral head flat, collapse, joint space narrowing or disappeared, cystic change Obviously, the larger bone sclerosis, Unit bone cartilage completely broken, the articular surface roughness.
