What to look out for in femoral head necrosis artificial replacement

Once the femoral neck fracture has a nonunion and femoral head necrosis, there are indications for joint replacement, and the common complication of femoral neck fracture is femoral head necrosis, and once the fracture does not heal the possibility of necrosis is almost 100%, it is unlikely to make the fracture heal through conservative **.

If the fracture is identified, surgery is now indicated, and early surgery can prevent joint contractures and allow early return to normal activities.

At present, the best way for mid-to-late femoral head necrosis is artificial femoral head replacement. For patients in their 40s or 50s, the general indication for surgery is appropriate, and this approach is often used. If the bones are loose, painful, or the bone parenchyma is diseased, the diagnosis can be confirmed after careful diagnosis.

These symptoms may suggest necrosis of the femoral head. See a doctor. Conservative ** also costs money.

In the case of surgery, there are many things to pay attention to, such as the patient's physical condition, the degree of necrosis of the femoral head, etc., as well as the patient's food, living habits, and replantation materials!

You should pay attention to finding a good hospital!

It can be used for 10 to 20 years, if the elderly have had joint replacement, then relatively less walking, less activity, and no heavy physical labor, then the use time will be relatively longer, at least 20 to 30 years.

Although the artificially replaced femoral head is mostly called medical steel, it is not permanently usable, and after this age, the replaced femoral head needs to be replaced again, and the patient who undergoes the replacement surgery will suffer more serious injuries.

1.Those who are old and frail, have serious heart and lung diseases, and cannot tolerate surgery.

2.Patients with severe diabetes.

3.Septic arthritis or osteomyelitis of the hip joint.

4.Tuberculosis of the hip joint.

5.Those with severe acetabular damage or obvious acetabulum degeneration. Surgery.

After the replacement of the femoral head necrosis, the patient's care plays an important role in the disease. Avascular necrosis of the femoral head caused by the trauma caused by surgery, causing inflammation and congestion and edema around the hip joint, reaching the peak in two days, and then entering the absorption stage of inflammation, edema and hematoma, this stage can vary depending on the size of the wound, the presence or absence of hematoma residue, the liquefaction of fat, the presence of infection and age, and the condition of the wound, generally about one month.

In the early postoperative stage, it is anti-infection, unobstructed drainage, elimination of hematoma, promotion of wound healing, and attention to the body's righting. After the suture is removed, it is important to further promote the absorption of local inflammation and edema and prevent and reduce adhesions around the joint, and at this time, the internal and external combination of blood circulation and blood stasis is emphasized. External treatment focuses on the external application of plasters, physiotherapy, massage, sitting-lying exercises under the bone (pelvic osteotomy, with the exception of capping) or passive leg lifting and hip flexion to prevent joint adhesions.

After one month**, the local tissues were soft, the hip flexion function gradually recovered, and the pain was reduced.

In addition, during the nursing period, it is necessary to follow the doctor's instructions and do not rush to achieve results, so as to reduce the probability of prosthetic complications.

Here are some of the disadvantages of replacement surgery:

First, the cost is high, the risk is high, and the trauma is large.

Second, the replacement of the femoral head has a high technical content, and a slight deviation in the position is easy to cause pain and even lifelong disability. Clause.

3. Even if the maximum service life of the artificial hip joint imported from abroad is only 10-15 years, the service life of the domestic artificial hip joint is only 5-6 years, and the operation needs to be performed again when the service life is reached. Therefore, in general, patients under the age of 60 are not recommended for surgical replacement. Hope this helps!
