What causes osteonecrosis?

Hello! What is osteonecrosis.

Osteonecrosis is the necrosis of bone cells, bone cells, and medullary cells (blood vessels and nerves), causing multiple interruptions or severe deficiencies in bone tissue, metabolic disorders of bone, and loss of nutrients in local bone tissue.

In principle, osteonecrosis is divided into two categories: one is osteonecrosis due to bacterial infection. Such as:

osteomyelitis, bone tuberculosis, septic arthritis, etc.; The other type is osteonecrosis due to ischemia. Such as osteonecrosis caused by trauma, alcohol consumption, hormone drugs, cold and dampness, liver and kidney deficiency, osteoporosis, flat hips, and dyssykenia of the spinal cord. Osteonecrosis can occur anywhere in the body.

Clinically, femoral head, humeral head, scaphoid bone, lunate bone, navicular bone, talus, ribs, patella, and clavicle are more common. In particular, the femoral head has the highest incidence. Osteonecrosis occurs in the femoral head and is called femoral head necrosis.

A: 1Long-term use of large amounts of glucocorticoids. 2. Drinking heavily for a long time. 3 have a history of hip trauma, 4 others: diving, pilots, hypertension, diabetes, arteriosclerosis, gout, those who need radiotherapy, post-burns, hemoglobinopathies, etc.

Causes of necrosis of the femoral head: 1. History of obvious trauma to the hip joint 2. Taking hormone drugs 3. Long-term alcohol abuse 4. Genetics, development, metabolism, etc. 5. Idiopathic (non-traumatic).

What are the dangers of advanced osteonecrosis? The hip joint is composed of the femoral head, femoral tibia, femoral axis, greater tuberosity, acetabulum, and pelvis, and it is the largest joint in the human body. The hip joint has a weight-bearing function that transmits the body's strength to the lower limbs.

At the same time, the hip joint can also do a considerable range of flexion, extension, abduction, internal rotation, external rotation and other exercises. Therefore, it is necessary to pay attention to the maintenance of the hip joint to avoid affecting the normal quality of life due to hip joint problems.

<> if femoral head necrosis occurs, several stages of femoral head necrosis must be diagnosed. If it is the first or second stage of necrosis of the femoral head, under normal circumstances, the patient's joints begin to feel uncomfortable, sometimes on one side, sometimes on both sides. However, good results can be obtained by being positive and conservative.

If it is the third stage necrosis of the collapse of the femoral head, it will inevitably cause arthritis, and hip arthritis will also aggravate the pain of the patient. Patients may have a little stiffness in their joints after walking for a long time, uncomfortable squatting up and down, and uncomfortable waking up in the morning, all of which are consequences of necrosis of the femoral head. If the necrosis of the femoral head occurs relatively late, it not only collapses, but also arthritis, which affects the patient's lumbar spine and affects the patient's knee joint, so the consequences of the fourth stage of femoral head necrosis are more serious.

In addition, if there is a problem with both sides of the femoral head necrosis, the patient will not be able to walk at this time and will need to be in a wheelchair. In later stages, patients will develop generalized osteoporosis, which is medically known as disuse osteoporosis. Therefore, patients with femoral head necrosis should be more aggressive in early diagnosis and early ** in order to have better outcomes.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

There will be severe pain, affecting the development of bones, unable to walk on the ground, loss of ability to work, physical resistance will be very poor, there will be a certain disability rate, will bring a huge economic burden to the family, if you find this situation, you should go to the hospital in time to seek medical treatment, the right medicine.

There may be a very severe collapse, and secondly, there may be a loss of ability to withstand pressure and the body will not be able to bear the weight at all. You may not be able to work, and you may become crutches when you walk in life. The most serious is necrosis of the femoral head.

Late osteonecrosis may lead to inability to work, loss of ability to work, inability to walk on the ground, severe pain in bones and joints, severe disability, increase the burden on the family, be sure to go to the hospital for diagnosis and treatment in time.

There will be symptoms of joint pain, or the phenomenon of lesions, which will also affect the function of the joints, or the phenomenon of pain, and various orthopedic diseases.

Symptoms of joint pain, or degeneration, also affect joint function, or pain, as well as various orthopedic diseases.
