SARS osteonecrosis

SARS sequelae refers to the general term for various sequelae caused by the large-scale use of hormones in the treatment and prevention of SARS in 2003. The side effects of hormones caused some SARS patients to develop symptoms such as organizing pneumonia, diffuse interstitial fibrosis, hip synovitis and femoral head necrosis. Among them, the treatment measure for bone necrosis left over from SARS patients is mainly artificial hip replacement, and the efficacy of this surgical technique is worthy of recognition.

1. Causes of SARS osteonecrosis

In 2003, in order to save lives, hormone drugs were used in large quantities for emergency treatment of SARS. The side effects of hormones caused femoral head necrosis and pulmonary fibrosis in some patients, which were called SARS sequelae. These people who seemed to have escaped the disaster back then are now suffering from the aftermath again. The side effects of hormones cause femoral head necrosis in some patients and psychological disorders due to discrimination.

2. Symptoms and treatment of femoral head necrosis

The most common symptom is pain, which occurs in the hip joint and proximal thigh and may radiate to the knee. Pain can be caused by necrotic tissue-repaired inflammatory lesions or high pressure within inflammatory lesions, and can manifest as constant pain or rest pain. Collapse and deformation of bone cartilage leads to traumatic arthritis, or chronic injury pain at the muscle and ligament attachment sites around the hip joint. Limited hip motion, particularly rotation, or painful and shortening claudication.

Treatment is the key to stopping the progression of the disease and putting it on the track of a benign outcome. For example, for alcohol and hormone poisoning, measures such as quitting drinking and terminating the use of glucocorticoids are taken. Through biological reactions, bone regeneration and repair of diseased tissue are promoted to make the repair as complete and effective as possible, restore the load-bearing capacity, and prevent deformation and collapse of the femoral head. Therefore, the second key treatment is to reduce weight-bearing, walk, reduce the load on the weight-bearing area of ​​the femoral head, and avoid microfracture and collapse of the weakened bone tissue. It is recommended that patients walk in small amounts and at intervals, and avoid jumping. During the progressive stage of necrotic lesions, they should rely on support to walk. Encourage patients to do stress-reducing exercises, such as cycling and swimming. During the acute progressive phase, it is advisable to stay in bed and avoid weight bearing. Drugs that promote bone and cartilage nutrition and growth can be tried. For those who are on the verge of collapse or have already collapsed and deformed, and who suffer from long-term pain and functional disabilities, artificial hip replacement surgery can be performed. The surgical technique is mature, the effect is definite, and the success rate is high.

3. Treatment of SARS sequelae

1. Femoral head necrosis

For those who are on the verge of collapse or have already collapsed and deformed, and who suffer from long-term pain and functional disabilities, artificial hip replacement surgery can be performed. The surgical technique is mature, the effect is definite, and the success rate is high.

2. Mental disorders

This allows them to enjoy more specific and subtle human warmth and care while fighting their illness.

3. Diffuse pulmonary interstitial fibrosis

Most of the cases are in the lungs, mainly for infection control, maintenance with small doses of hormones, oxygen therapy, etc.

4. Post-SARS syndrome

The fundamental method is to enhance human immunity.
