What are the stages of femoral head necrosis? What are the characteristics?

Necrosis of the femoral head is divided into: stage 0.

Biopsy findings consistent with necrosis.

Let's see what others have to say.

In this phase (pre-radiation phase), about 50% of patients have mild hip pain that worsens with weight bearing. Physical examination: limited hip motion, first seen with limited motion with internal rotation, and hip pain worsening with strong internal rotation.

X-ray: may be negative, or sporadic osteoporosis or trabecular bone is blurred.

The clinical symptoms of stage (necrosis formation, pre-head flattening) are obvious and aggravated compared with stage I. X-rays show extensive osteoporosis of the femoral head, scattered sclerosis or cystic changes, trabecular bone disorder and interruption, partial necrosis area, and normal joint space.

The clinical symptoms continue to worsen during the transition phase. X-rays showed that the femoral head was mildly flattened, collapsed within 2mm, and the joint space was slightly narrowed.

The clinical symptoms are more severe in the collapse stage. The function of the lower limbs is significantly limited, the pain is mostly relieved or disappears, and the muscles of the affected limb are atrophied. X-rays showing:

The outer contour of the femoral head and trabeculae are disordered and interrupted, with a semilunar sign, collapse greater than 2 mm, dead bone formation, flattening of the head, and narrowing of the joint space.

The clinical symptoms of the stage (osteoarthritis stage) are similar to those of osteoarthritis, with significant pain and severe limitation of joint range of motion. X-rays show collapse of the femoral head, marginal hyperplasia, fusion or absence of joint spaces, and hip subluxation.

Correct diagnosis and staging are closely related to the method and effect of decision-making. If osteonecrosis is detected early or suspected, magnetic resonance imaging (MRI) or CT scan can be continued. However, the above two examinations are more expensive, so it is generally recommended that patients take anteroposterior pelvic x-rays, or add bilateral medullary x-rays, and flex the hip to 90deg; Outer booth hip piece.

Because the degree of femoral head disease is different, its stage is also different. It will be different when the patient is **. However, the early stage of femoral head necrosis is a better stage, and patients must seize the opportunity to go.

1. Early symptoms In fact, the stage of femoral head is very obvious, and the symptoms are different in different periods. In the early stages of femoral head necrosis, symptoms are often subtle, and some patients may have pain, which may be intermittent or continuous, worsen with walking, and 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.

Early femoral head necrosis x-rays show only decreased blood circulation around the femoral head, osteoporosis, and a small number of cystic changes. Therefore, it is often misdiagnosed as rheumatism, lumbar spondylosis, knee joint disease, etc. 2. Medium-term symptoms When the femoral head necrosis reaches the middle and late stages, the symptoms will become more and more obvious.

The symptoms of necrosis of the femoral head in the middle stage mainly include claudication, walking pain, dysfunction, and when taking X-ray, most of the trabecular bones will be lost, cystic changes, bone sclerosis, and the cartilage of the femoral head will be broken and collapsed. 3. Late symptoms When the symptoms of necrosis of the femoral head are in the late stage, the legs are obviously short, difficult to walk, and painful, and the femoral head will be flattened and collapsed, the joint space is narrowed or disappeared, the cystic changes are obvious, the area of osteosclerosis is large, the cartilage of the femoral head is completely broken, and the articular surface is rough. We all know that the clinical signs of femoral head necrosis are different, so we must not be mistaken.

These are some of the clinical signs of the staging of femoral head necrosis. I hope it can be helpful to you, and at the same time, I also remind you to go to the hospital as soon as possible, and the timely use of DSA intervention and integration is of great help to the condition. So be sure to detect it early**.

And be sure to go to a regular specialist hospital for **.

The following is an introductory *************** from the Femoral Head Referral Center of the Second Hospital of the Beijing Armed Police Corps

According to the symptoms of necrosis of the femoral head, the disease can be divided into three stages: early, middle and late:

1.The early symptoms are mainly intermittent pain in the hip joint, and the legs will feel soreness and pain after walking for a long time, which will be relieved and return to normal after rest, and can only be examined by MRI and ECT in the early stage.

2.The mid-term symptoms are mainly manifested as intermittent aggravation of hip pain, claudication when walking, limited hip movement, difficulty in lifting legs and squatting, and it can be seen from X-rays that the proximal femoral head may appear in the proximal end of the femoral head in the form of a crescent bud-shaped or ova-like necrotic area with increased bone density, and some of the femoral heads are slightly flattened.

3.The late symptoms are mainly manifested as a sudden aggravation of intermittent pain in the hip joint, greatly limited hip joint movement, severe restrictions on abduction, adduction, elevation, and squatting, obvious claudication, muscle atrophy, weakness of the lower limbs, and even loss of ability to work. X-rays show that the femoral head collapses and is significantly deformed, the articular cartilage is completely destroyed, the joint space is narrowed, the necrotic area is enlarged, and the subchondral fracture, collapse, and crescent formation are formed.

In simple terms, there are the following issues:

Stage 1: The lesion is in the early stage, there is no obvious change in the outcome and morphology, there is an excess of blood vessels, and there is no change in bone and bone marrow.

Stage 2: In the advanced stage of necrosis, necrotic tissue collapse can be seen, and surrounding tissue repair occurs, the morphological changes of necrotic tissue are more obvious, and osteosclerosis can be seen on X-ray.

Stage III: Necrosis repair stage: irregular dense shadows can be seen on X-rays, and areas of decreased bone mineral density and areas of increased bone density are alternate.

Stage 4: In the later stage, the femoral head collapsed, and although it was repaired, the trabecular of the new bone was not arranged in an irregular manner, the shape was different, and the thickness was different. X-ray deformation of the joint provokes manifestations of hanging arthritis.

An expert on necrosis of the femoral head of the Second Hospital of the Beijing Armed Police said that the necrosis of the femoral head at this time was very serious, and ordinary hospitals could not cure it, so it was necessary to choose a hospital carefully.

After taking the hormone drug prednison itraconazole oral liquid for nearly two and a half years, it was found that the avascular necrosis of the femoral head was like**.

In 5 installments. In stage 0, osteocyte necrosis was seen in the pathology, but the imaging was normal.

1: MRI can show changes, the radiograph is normal, the patient can be asymptomatic 2: X-ray can show changes in femoral head density, but the femoral head morphology is normal, and the hip joint may have pain 3: The femoral head collapses, flattens, and the hip joint suffers.

4: Flattening of the femoral head, involvement of the acetabulum, osteoarthritis of the hip joint.

Hello! Necrosis of the femoral head is divided into four stages:

Stage 1 Manifestation: The physical symptom response is not obvious, and local discomfort occurs after exertionThe second stage manifestation: Hip discomfort or pain occurs after exertion, which can be improved with rest.

Stage 3 manifestations: severe pain, pain at rest.

Stage 4 manifestation: severe pain with functional impairment.

I hope it helps you and sincerely wish the patient a speedy **!

The shape of the femoral head did not change in the first stage, and the trabecular bone changed, resulting in uneven density of the femoral head. The patient presents with soreness or tingling around the hip joint; Cold or exertion worsens, relieved with rest.

In the second stage, there is separation of cancellous bone from subchondral bone, forming a crescent sign without collapse of the femoral head.

In the third stage, there was collapse of the femoral head, no significant change in the acetabulum, and the joint space was normal.

Stage 4 is degenerative hip joint with narrowing of the joint space and ankylosis of the joint.

The first and second phases were conservative** to improve blood circulation in the femoral head. Stage III requires surgical interventions to improve blood circulation, such as implantation of tantalum rods in the bone tract or iliac flaps with vascular pedicles. Stage 4 requires joint replacement to improve function and quality of life.

The stage of femoral head necrosis is mainly divided into 4 stages, stage 0 is that the biopsy results are in line with the bad thing, but other examinations are normal, stage 1 is mainly abnormal by bone scan or magnetic resonance examination, stage 2 has uneven density of femoral head patches, sclerosis or cyst formation, radiation will cause bone density reduction, but there is no femoral head collapse, stage 3 can be seen in the anterolateral view of the nova moon, stage 4 is mainly manifested by narrowing of the articular surface, narrowing of the space, and necrosis of the acetabulum. For example, drinking habits should be stopped in time, and at the same time, hormones should also be used to stop using hormones, and then early suggestions are given to encourage patients to carry out ten exercises to reduce the burden, such as cycling and swimming, etc., and should be bed in the acute advanced stage, avoid weight-bearing, and can use some drugs to promote the growth of jaw and cartilage nutrition and height.

Femoral head necrosis is divided into early, middle and late stages, this is not a serious disease, early detection on the hurry, no need to do surgery, take some medicine on it, Baidu search Tongluo bone capsule to understand, this is Chinese patent medicine for femoral head necrosis is very effective, and now there are activities, you can get femoral head necrosis for free. Yours is always my support.

Hello Pre-radiation period, pain is predominant, and the symptoms are not obvious; The necrosis of the femoral head is formed, the clinical symptoms are obvious, and the head is intact when the stage is aggravated; During the transitional phase, the clinical symptoms continued to worsen, and the femoral head collapsed slightly; During the collapse phase, there is the formation of dead bones, the flattening of the femoral head is aggravated, and the joint space is narrowed; In the stage of osteoarthritis, the clinical symptoms are similar to those of osteoarthritis, the pain is obvious, the joint space is further collapsed, and the joint space is fused or disappeared, and the hip subluxation occurs.

Finally, the necrosis of the femoral head should be done sooner rather than later. And no matter what stage of the patient's condition is, finding a positive and effective way to cultivate a positive attitude is the key.

Hope it helps.

Femoral head necrosis is divided into: early, middle, and late. Osteonecrosis is a common orthopedic disease in which blood circulation to the femoral head is blocked, i.e., arterial hypoperfusion and venous return are blocked, resulting in increased intraosseous pressure.

If you don't get timely and regular **, you will miss the best ** opportunity, and further deteriorate to necrosis of the femoral head, coupled with weight bearing (such as walking, climbing stairs, carrying things, etc.) causing the femoral head to collapse, forming osteoarthritis, and the final result is that the patient is disabled. The peak age of incidence is around 30 years old. At present, the incidence of avascular necrosis of the femoral head due to hormone abuse and excessive alcohol consumption is on a linear upward trend.

However, the initial stage of femoral head necrosis is not terrible, and comprehensive scientific methods such as preventing early muscle dystrophy can achieve the goal of complete **. From the point of view of scientific research and clinical observations, the earlier the better.

I sincerely wish you good health, a lifetime of happiness and a wonderful life.
