Femoral head necrosis initial symptom?

summary

Some people may not understand the symptoms of osteonecrosis of the femoral head, but they need to know if they want to find them as soon as possible. In fact, the symptoms of osteonecrosis of the femoral head are very easy to judge. If you can have some symptoms, you need to be alert. Then, let's take a look at the initial symptoms of osteonecrosis of the femoral head?, I hope the following introduction will help you.

Femoral head necrosis initial symptom?

The symptoms and signs of avascular necrosis of the femoral head are various, and the time and degree of the pain are not the same, but they are all based on the pathological evolution. In other words, it is difficult to make the diagnosis of femoral head necrosis by subjective symptoms and clinical examination.

For example, many lesions of the hip and sacroiliac joint can show positive "4" test (that is, bend the knee and make the hip flexion abduction and external rotation, put it in a "4" shape on the opposite side of the leg, press the opposite iliac crest with one hand, and press the other hand on the inside of the knee at the same time, causing hip pain). Therefore, it is not a specific sign for the diagnosis of femoral head necrosis.

The most common symptom is pain, pain is the hip, proximal thigh, can radiate to the knee. Pain can be caused by necrotic tissue repair inflammatory lesions or high pressure in inflammatory lesions, which can be manifested as persistent pain and resting pain. Osteochondral collapse and deformation can lead to traumatic arthritis, or chronic injury pain of muscle and ligament around hip joint. Hip movement limitation, especially rotation limitation, or painful and shortened claudication.

matters needing attention

Avoid alcohol abuse and avoid glucocorticoids as much as possible. In the internal fixation of femoral neck fracture, we should strive to achieve anatomical reduction. For the patients with frequent collapse or deformation, long-term pain dysfunction, artificial hip replacement is feasible. The operation technology is mature, the effect is certain, and the success rate is high.
