Causes of femoral head necrosis

Generally speaking, there are several reasons for femoral head necrosis. The most common one is long-term and excessive use of hormones. For example, people with systemic lupus erythematosus or asthma need to take hormones for a long time, and the chance of femoral head necrosis increases significantly. Another is femoral neck fracture caused by trauma, especially subcapital femoral neck fracture, which has a higher chance of femoral head necrosis. Another is long-term alcoholism. Decompression sickness, also known as diving sickness, is a sudden change from a higher pressure to a lower pressure, causing fat tissue in the blood to block blood vessels, resulting in femoral head necrosis. Another is hemoglobinopathy. Radiotherapy can also cause femoral head necrosis.

Symptoms of femoral head necrosis

Femoral head necrosis is mainly caused by trauma, alcoholism, long-term use of hormone drugs and other reasons. The main symptoms are pain in the hip joint and proximal thigh. The pain can radiate to the knee joint and cause hip joint dysfunction. For the treatment of femoral head necrosis, the first thing to do is to get rid of the bad habits that induce femoral head necrosis. Secondly, pay attention to rest and avoid weight bearing. Non-steroidal anti-inflammatory analgesic drugs, cartilage nutrition drugs, traditional Chinese medicine, physical therapy, drilling decompression and other methods can be used to improve symptoms and delay the progression of the disease. In the later stage when dysfunction occurs and conservative treatment is ineffective, joint replacement surgery can be performed.

Spontaneous healing of femoral head necrosis

Guan Jingtao, attending physician of orthopedic surgery, said that the statement that femoral head necrosis can heal itself is wrong. Femoral head necrosis will not heal itself. Even if the pain or limited movement in the local area of ​​femoral head necrosis is significantly improved by taking medicine or undergoing local physical therapy, it does not mean that femoral head necrosis can be cured or the condition can be reversed, or that it can be cured by medicine or other treatment methods. In other words, femoral head necrosis can be controlled and its further development can be delayed by medicine and other treatments, but the lesion is irreversible after all.
