Is it easy to misdiagnose necrosis of the femoral head in the early stage?

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 head fractures should be treated promptly**. The best way to deal with this disease is early detection, early diagnosis, and early **.

The early symptoms of femoral head necrosis include: lower back pain, hip pain on the affected side, pain in the groin area, pain in the knee joint, chills in the affected limb, weakness and soreness during excessive activity, and fatigue.

Manifestations of lower extremity chills: there are always symptoms of lower extremity chills, which occur at the same time as the symptoms of lower limb weakness in the early stages of femoral head necrosis. In a period of time, the patient feels that the lower limbs are afraid of cold, the lower body does not dare to wear too little, there is always some cold feeling, the temperature is slightly lower, and the lower limbs can be most sensitively felt, especially the sensitivity to air conditioning and electric fans.

The weakness of the lower limbs is manifested by the fact that the legs are easily tired when walking, and the legs feel heavy and do not want to continue walking, and at the same time, there will be thoughts of resting the feet. If you feel weakness in your lower limbs while walking, take a break and this symptoms of weakness and fatigue will disappear.

Doctors ask the patient about the history, physical examination, and necessary ancillary tests to confirm the diagnosis.

1) The medical history includes: the time, nature, severity, and location of the pain. Whether there is a history of trauma, hormone use, alcohol consumption, etc., and know about the past, occupation, hobbies, and family history.

2) Physical examination: observe the patient's gait, check the range of motion of the hip joint, measure the length and circumference of both lower limbs, local tenderness of the hip joint, and do the "4" test of both lower limbs, Thomas's sign, Ellis's sign and percussion test.

3) Auxiliary examination: mainly rely on X-ray, because it is convenient and economical, and can be taken in general hospitals. X-ray film requires good contrast in the anterior and frog positions, and the trabeculae of the femoral head can be seen clearly.

For patients with high clinical suspicion or inconclusive x-rays, magnetic resonance imaging and ECT are the options.

These symptoms in the early stage of femoral head necrosis are not on the hip joint, and the frequency of occurrence is not the same. These symptoms generally do not occur at the same time in a single patient, so it is difficult for inexperienced orthopedic surgeons to correctly diagnose femoral head necrosis in the early stage, which is also the reason for the high rate of early misdiagnosis of femoral head necrosis. Therefore, when these symptoms appear, you should go to the hospital for MRI examination in time to detect necrosis of the femoral head early and accurately, which can get a positive and effective ** and reduce the disability rate.

Hello: Femoral head necrosis (ANFH) is a lesion in which the local blood circulation of the femoral head is poor due to a variety of reasons, resulting in further ischemia, necrosis, trabecular fracture, and collapse of the femoral head.

This disease begins to manifest as a dull and dull pain in the hip joint or its surrounding joints, which worsens after activity, and further development can lead to dysfunction of the hip joint, seriously affecting the patient's quality of life and ability to work. The main symptoms are: walking limp, pain, weakness of the lower limbs, difficulty in moving, inability to walk in severe cases, muscle atrophy and even paralysis.

If it is not timely, it will be disabling and paralyzed.

The harm of femoral head necrosis is very large, it brings a heavy burden to the body and spirit of the patient, and the broad masses of people lack sufficient understanding of femoral head necrosis, either talk about femoral discoloration, or completely ignore it. In fact, after years of research, necrosis of the femoral head has obvious pathological features in clinical practice or in the patient's self-perception.

Suggestion: What will be the consequences of femoral head necrosis if it is not treated? The hazards of femoral head necrosis mainly have the following characteristics:

Pain, claudication, joint stiffness and limited mobility, and in severe cases, disability, etc. Let's take a look at them one by one: First, pain.

As we all know, if the pain in a certain part of the body is severe, the impact on the patient's life is very large. Pain may be intermittent or constant in the case of femoral head necrosis, worse with walking or activity, 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.

Second, joint stiffness and limited mobility. Patients with femoral head necrosis often feel that the affected hip joint is not flexion and extension, and it is difficult to squat and cannot stand for a long time, and duck steps appear when walking. Early symptoms are abduction and limited external rotation activities.

Third, limp. Of course, the claudication of patients with femoral head necrosis is progressive shortening claudication, which is mainly due to hip pain and collapse of the femoral head, or the development of hip subluxation in the later stages. Intermittent claudication tends to occur in the early stages, especially in children.

In addition to which of the above, the risk of femoral head necrosis is manifested in limited abduction, external or internal rotation, shortening of the affected limb, muscle atrophy, and even signs of subluxation. Sometimes axial rush is positive. Small or interrupted bone textures, cysts, hardening, flattening or collapse of the femoral head, etc.

Hello, femoral head necrosis is a very common orthopedic disease, due to its anatomical location deep in the muscle layer, which is one of the factors that are not easy to detect in the early stage of femoral head necrosis. The harm of femoral head necrosis is often that bone cells have been necrotic, trabecular disorder, deformation and atrophy in the course of the disease, or there have been insect erosion-like changes, punctate sclerosis, and the patient has no symptoms. As the disease progresses to an advanced stage, patients can clearly feel the pain and limited mobility of the affected limb, and at the same time, the patient will suffer from psychological trauma while suffering from physical pain, which will increase the heavy burden on family, work unit and society.

Here are some simple and easy-to-tell methods excerpted from the orthopedic department website of the Guangxi Armed Police Corps Hospital to help you diagnose whether you have femoral head necrosis.

1. Hip pain radiates to the groin area or the posterior or lateral side of the buttocks or the inside of the knee.

2. Hip stiffness, weakness, limited movement, inflexibility of leg lifting, early symptoms are cross-legged or outward leg skimming and difficulty in squatting.

3. Lameness: that is, the affected limb does not dare to bear weight when walking, and walks like tiptoe.

4. After the fracture, dislocation or hip sprain heals, intermittent or persistent hip pain occurs gradually or suddenly. It is worse with walking activity, sometimes at rest, and the pain is usually pinprick or sore, and the above reactions occur.

5. Long-term or short-term use of a large number of hormones or frequent alcoholics have hip pain, mostly dull pain, often located in the groin, obvious during activity, relieved after rest.

6. Cold and dampness: When the weather is cold, the hip joint is sore, the pain is aggravated, and the function is limited.

7. Inflammation: When you have a cold and fever, the erythrocyte sedimentation rate is accelerated, the white blood cells are increased, and the pain in the hip joint on the affected side is aggravated.

MRI is very accurate in the diagnosis of early femoral head necrosis

Delayed treatment of any disease can have increasingly serious effects, as does necrosis of the femoral head. According to statistics, 80% of patients with femoral head collapse and bedridden femoral head necrosis are due to the misdiagnosis of early femoral head necrosis, resulting in serious consequences of inactivity and disability.

Symptoms and signs of early femoral head necrosis.

Although necrosis of the femoral head is a problem of the hip joint, the early symptoms do not appear in the hip joint, and the three main symptoms are: occasional pain in the lower back, chills in the lower limbs, occasional pain in the knee joint, and vague pain in the hip joint (the most common). <

1. The symptoms of low back pain mask the real necrosis of the femoral head.

Necrosis of the femoral head can coexist with lumbar spondylosis, and there are several cases:

Lumbar intervertebral disc herniation is a common clinical disease, and typical cases can present with numbness and pain in the lower limbs, especially in the presence of sciatic nerve pain, which can easily mask the crotch pain caused by necrosis of the femoral head.

Doctor"Preconceived"It is easy to be misled by the description of the condition of the patient or family members, and ignore the necessary basic clinical physical examination.

In particular, a hip physical examination. Some patients emphasize that they have lumbar disc herniation as soon as they meet with the doctor, and the doctor believes it and ignores the hip pain caused by necrosis of the femoral head. <>

How to tell if it is femoral head necrosis or lumbar disc herniation:

1. From the perspective of the early pain location, the necrosis of the femoral head is a vague pain in the groin area of the anterior side of the thigh; Early pain in lumbar disc herniation is radiating pain in the hips, back of the knee and back of the lower leg. 2. From the perspective of accompanying symptoms: lumbar intervertebral disc herniation will be accompanied by signs of numbness in the lower limbs, while necrosis of the femoral head will not occur.

Two. Presents with knee pain.

Due to the principle of femoral innervation, some patients with femoral head necrosis do not have typical hip pain, but present with knee pain, especially medial knee pain. If the doctor is inexperienced and the knee examination has signs of intra-articular degeneration (osteoarthritis manifestations), it is easy to misdiagnose knee osteoarthritis or miss the pre-existing necrosis of the femoral head.

Three. The patient has a systemic disease.

When patients have rheumatism, such as rheumatoid arthritis or ankylosing spondylitis or gout, especially those who receive hormones**, it is easy to miss the diagnosis because they usually have pain and discomfort in multiple joints. <>

Be cautious. If you have hip pain for more than 2 months, you need to go to a regular femoral head hospital for screening as soon as possible, and the most reliable way to diagnose early femoral head necrosis is to have an MRI image. Femoral head necrosis can be cured as long as it is detected in time, and it is not an incurable disease.

Many patients in the early stages of stage I and II continue to deteriorate due to the lack of timely diagnosis, resulting in the deterioration of the femoral head and finally the collapse of the femoral head and paralysis. Therefore, it is really important to diagnose the diagnosis as early as possible and clarify the condition!

Because the bone is necrotic, it is not easy to be detected when taking a CT scan, and the meat next to it wraps the bone, so it is not easy to be detected, so it will be missed.

Because it itself is not easy to find, it will naturally be easy to ignore, very normal, indeed difficult to diagnose, easy to be confused.

Because there are many symptoms in the early stage of femoral head necrosis, you can't see it if you don't pay attention. And it can be accompanied by other diseases.

Necrosis of the femoral head is a common refractory disease in orthopedics. In recent years, the incidence of femoral head necrosis has gradually shown a younger trend, and many patients are in the most critical period of life and career, so it has become urgent to effectively prevent and improve femoral head necrosis. However, in clinical practice, it is common to encounter a large number of patients with necrosis of the femoral head who are missed, misdiagnosed, or misdiagnosed**.

Many patients with femoral head necrosis have no symptoms in the early stages. Intermittent pain is a common symptom in some early patients, the pain location often occurs in the groin and radiates to the inner thigh and knee joint, and sometimes the patient's friends even suspect that it is a knee joint disease, so they often go to the hospital for knee examination, and some patients have hip pain, the pain can occur suddenly, or it can be insidious and gradual, and the severity of pain in different patients is also quite different. If hip pain usually disappears at rest, worsens with joint motion, or even limps, and doctors examine the patient and find that the hip is limited in motion, especially internal rotation, then necrosis of the femoral head is highly suspected.

What are the benefits of early diagnosis for necrosis of the femoral head?

Experience at home and abroad has proved that if the necrosis of the femoral head is not effective before the collapse of the femoral head, more than 80% of the femoral head will collapse in 2-3 years, and 78% of the necrotic femoral head that collapses will develop to the extent that artificial joint replacement is required within 2 years, and the long-term efficacy of replacement surgery in young and middle-aged patients is not better than that of elderly patients. After decades of research on the disease, much progress has been made in the early diagnosis and experience of femoral head necrosis. <>

Scientific and systematic drug hip preservation methods can be selected, and the efficacy is certain. The earlier the detection of femoral head necrosis, the higher the success rate of hip preservation** and the lower the cost to the patient. Therefore, if the patient has physical discomfort, especially the hip joint, it is important to pay attention to early diagnosis.

Because early diagnosis of such patients can make them get the best results early, have better results, and can effectively prevent related complications, and can also shorten the course of the disease, thereby preventing patients from long-term pain and reduced exercise capacity.

Personally, I think that early diagnosis of femoral head will die, can be prevented in advance, and can also be maintained in advance, and I will take great care of my body, so to diagnose early, femoral head necrosis will be intuitively important.

Early diagnosis and early diagnosis**, early diagnosis can be timely measures** to inhibit the further deterioration of the condition, ** higher probability of success.

Because if the femoral head necrosis is not diagnosed at an early stage, it will bring a lot of inconvenience to life, humeral head necrosis will cause walking pain, and it will be more inconvenient to move as you get older.

If bone necrosis is not diagnosed in time, there is a high risk of paralysis. It can even be life-threatening.
