Pain is the main symptom of femoral head necrosis . Early femoral head necrosis generally suffers from not obvious pain and is easily overlooked by patients. As the femoral head necrosis develops, the pain of femoral head necrosis will generally become intermittent pain, which means that the pain will be relieved after a period of time and will be repeated. We generally divide it into the following stages:
1, synovial edema
Hip pain will significantly aggravate, and joint function will be significantly limited. After bed resting, using crutches, and taking medication, the pain will generally be significantly relieved.
2. The collapsed early stage
. Some trabecular will break, and the pain will gradually worsen. If the condition is stable and the trabecular trabecular is well repaired, the pain will gradually be relieved, and even reach a mild or painless state.
3. During the collapse period, the bone trabeculae continues to break continuously, the collapse continues to aggravate, the joint mobility becomes worse and worse, and the pain will also progressively aggravate.
4. In the late stage of femoral head necrosis,
generally suffers severe pain and obvious limitation of joint movement. Of course, there will be individual situations, that is, in the late stage of femoral head necrosis, bone repair and collapse will proceed simultaneously. After collapse, bone compression will be performed, and , femoral head will become smaller. At this time, the bone mass in the femoral head will be stable, and joint function will be restricted, but the pain will be reduced.
Clinically, pain is a symptom of femoral head necrosis. To judge the repair of femoral head necrosis, we cannot judge it based solely on the pain of femoral head necrosis. We need to make a common judgment based on the mobility of hip and imaging.
