Hip replacement has surgical risks. Injury to blood vessels during operation can lead to massive bleeding, and injury to sciatic nerve can lead to weakness, numbness and foot drop on one side of the affected limb. Femoral shaft fracture, postoperative prosthesis loosening, dislocation of hip joint, venous thrombosis of lower limbs, etc.

The elderly patients are in poor health and the wound is not easy to heal. In addition, severe cases can be complicated with wound infection, leading to perennial wounds. All operations are risky. Doctors should take every patient seriously and try to reduce complications.

Hip replacement has certain advantages and disadvantages. The advantage is hip replacement.

Surgery can quickly restore the patient's hip function and replace the non-disabled hip joint. The disadvantage is that. After hip replacement surgery, some patients may have complications, such as infection, loosening, dislocation or osteolysis. All prosthesis installation procedures have certain shortcomings.

Patients can weigh the advantages and disadvantages before treatment. So, what are the risks of hip replacement? If you look at the chart below, this is only the main risk. Doctors can list as many major problems at home and abroad as possible for decades (alas, because of the medical environment). Therefore, it takes more than half an hour to communicate with the patient and sign the consent form for surgery.

What are the special risks? So the special risk, the special risk, is that the femoral head necrosis of hip replacement is different from other operations, which occurs less and more. In fact, there are many special risks, such as infection, joint looseness, joint dislocation, congenital fracture, unequal length of long legs, deep vein embolism, heterotopic ossification, etc ..... Here I choose two more important ones, one is infection and the other is deep vein embolism.

What are the countermeasures after the problems appear? According to the problems at different stages and different infected microorganisms, different treatment methods are adopted, including conservative treatment with antibiotics, debridement of prosthesis, revision surgery and open surgery ... Of course, how to choose these measures is a problem that doctors need to consider carefully, and doctors also have evidence-based medical evidence as a reference to guide treatment, so that patients don't have to worry.
