What are the pre necrotic symptoms of femoral head?

The early clinical symptoms of femoral head necrosis are not obvious, and the first symptom is a dull or dull pain in the hip joint, which worsens after exertion. It is often accompanied by adductor pain, discomfort in the hip joint after exertion, but there is no impaired mobility, sometimes the pain can radiate to the inside of the knee, and the weather is cold and wet. These include:

1. Pain. or intermittent or persistent pain that worsens with activity, sometimes at rest. The pain is mostly pinprick, dull or sore, and often radiates to the groin area, inner thighs, posterior buttocks and inner knees, and there is numbness in this area.

2. Joint stiffness and limited mobility. The affected hip joint is not conducive to flexion and extension, difficulty in squatting, inability to stand for a long time, and walking duck steps. Early symptoms are abduction and limited external rotation activities.

3. Limp. It is a progressive shortened claudication due to hip pain and collapse of the femoral head, or late hip subluxation. Intermittent claudication tends to occur in the early stages, especially in children.

Femoral head necrosis is often misdiagnosed because of the lack of obvious symptoms in the early stages, so as to delay the disease. So what exactly are the early symptoms of femoral head necrosis? 1.

Necrosis of the femoral head The first perceived symptom is pain, which appears in the lower back, around the hip joint, inside and front of the thighs, groin, or in the knees. Early pain is dull and intermittent, worsens with activity, and is relieved or relieved at rest. or pain that is constant and gets worse gradually.

There are no obvious abnormal morphological changes on the line, but the hip joint has different degrees of functional limitations, such as: abduction and internal rotation of the hip joint on the affected side, squatting is not in place, etc. 3.

The affected limb is sensitive to chills, weakness during long movements, soreness, and fatigue. These symptoms do not appear at the same time, and may appear one or two or a few symptoms, appear for a short period of time and then disappear, repeat many times or persist. Femoral head necrosis Early symptoms should be done in a timely manner by going to the hospital for CT or MRI.

Plain x-rays alone cannot confirm the diagnosis of early necrosis of the femoral head because plain x-rays show only rough surface of the femoral head and a small number of small cysts in the head. Experts from Chongqing Yiqing Hospital of Traditional Chinese Medicine pointed out that when there are changes in the femoral head on X-ray, the necrosis of the femoral head has reached the middle and late stages, and the femoral osteoporosis and a small number of cystic changes.

In addition, because of the increased internal pressure of the femoral head, the pain is obvious, and it is easy to be misdiagnosed as rheumatism, lumbar spondylosis, knee joint disease, etc. Nowadays, many doctors only focus on the patient's pain symptoms, and often use some painkillers or occlusion, etc., so that the patient thinks that the pain symptoms disappear, and the disease will be gone. But I don't know that the best time for patients with femoral head necrosis has been delayed.

Therefore, doctors and patients should have a certain knowledge of prevention and treatment of femoral head necrosis, and should not miss the opportunity of early diagnosis and early femoral head necrosis because of misdiagnosis.

Early symptoms of necrosis of the femoral head: pain, ipsilateral hip pain, ipsilateral groin pain, limb knee pain, chills in the limbs, weakness of movement, pain, fatigue. These symptoms can appear at the same time, and there seems to be one or several symptoms or symptoms that appear and disappear for a short time and repeat many times.

Femoral head necrosis generally produces sequelae, and its main symptoms are not the same in different periods, and the femoral head necrosis experts of Jinan 106 Hospital briefly analyze the different signs of sequelae in different periods.

Sequelae of the femoral head: subchondral fracture of the femoral head, separation of trabeculae from cartilage, multiple crack-like translucent band-like changes in the femoral head, and normal or basically normal appearance of the femoral head. By **, 95% of patients live and work completely** and like normal people.

Sequelae of the femoral head: subchondral fracture of the femoral head, separation of trabeculae from cartilage, multiple patchy or band-like sclerotic high-density bone changes in the femoral head, signs of collapse and flat hypertrophy of the femoral head, and loss or loss of trabeculae. After **, 85% of the patients were clinically **, able to walk the hip joint without pain, claudication, basically normal function, normal appearance and image when walking, and non-heavy physical work could be carried out normally.

And in the clinical** patients, 20% of patients have severe femoral head collapse, flat femoral head, and severe hyperplasia on the lateral side of the femoral head.

Sequelae of the femoral head: bone fracture of the femoral head, loss or most of the trabeculae, multiple large-area cystic light transmission changes in the femoral head, multiple sclerosing high-density bone changes, severe collapse and deformation of the femoral head, flat hypertrophy, and joint space narrowing of more than 2mm or disappearing.

Early symptoms of necrosis of the femoral head:

The main symptoms are pain in the side buttocks or groin or lower back, stretching pain in the knee joint, chills, weakness, soreness, and numbness in the lower limbs. These symptoms do not necessarily occur at the same time, and may manifest as only one or two, which may persist or disappear in the short term.

Interim symptoms of femoral head necrosis:

The main manifestations include claudication, walking pain, abduction, adduction, and dysfunction of the hip joint. X-rays show sclerotic bone formation, sac-like changes, partial loss of trabeculae, and collapse and fracture of the cartilage of the femoral head.

Late symptoms of necrosis of the femoral head:

Patients with femoral head necrosis have more severe claudication, difficulty in walking, pain, obvious muscle contraction of lower limbs, weakness of lower limbs, chills, difficulty in squatting, difficulty in abduction and adduction; At this time, the X-ray will show that the femoral head is flattened, the joint space is narrowed or disappears, the cystic fingers are unbridled and obvious, the sclerotic bone area is large, the cartilage of the femoral head is completely broken, and the articular surface is uneven, which is the late stage of femoral head necrosis. For femoral head necrosis, most patients are secondary, that is, due to the femoral head fracture is not scientifically sized, reasonable nutritional intake, and active and moderate exercise. Therefore, it is recommended that patients with femoral bone fracture should be treated in a timely manner**.

The best way to deal with this disease is early detection, early diagnosis, and early **.
