Femoral head necrosis (also known as aseptic necrosis of the femoral head or ischemic necrosis of the femoral head), is a type of osteonecrosis. Osteonecrosis is caused by damage to the trophoblastic vessels of the bone due to a variety of reasons, which further leads to ischemic degenerative necrosis of the bone.
Femoral head necrosis is also a lesion caused by localized poor blood flow to the femoral head for a variety of reasons, leading to further ischemic necrosis, fracture of bone trabeculae, and collapse of the femoral head, which can occur at any age, but most often at the age of -. This disease can occur at any age, but is most common at the age of -. There is no gender difference, and it mostly starts with vague and dull pain in the hip joint or its surrounding joints, which is aggravated after activities.
Clinical manifestations of femoral head necrosis.
Femoral head necrosis takes hip joint pain and limp as the main clinical manifestation, the pain is mostly progressive, and there can be no clinical symptoms in the early stage, but it is found when CT film or X-ray is taken. The pain can be continuous or intermittent, and alternating pain can occur if the lesion is bilateral. The pain is often aggravated by prolonged standing and walking, and can be relieved by bed rest with painkillers. Patients with limited hip joint activities are mainly restricted in abduction and internal rotation, so patients may show that they cannot cross their legs and have difficulty getting on and off the bicycle, but once they are on it, they can still ride the bicycle. In severe cases, hip flexion and extension are also limited, manifesting as the inability to squat, inconvenience when bending, and the need to use the toilet when defecating. If this disease is not treated in time or improperly treated, it can cause severe disability and loss of working ability.
Preventive care for femoral head necrosis.
Pay attention to weather changes wind, cold and dampness again injury
Avoid alcohol hormonal anti-inflammatory and analgesic drugs
Avoid aquatic products because aquatic products can cause metabolic disorders in the body triggering gouty arthritis joint anomalous swelling and pain
Underarm crutches to reduce weight bearing
Strengthen indoor functional exercise (such as internal rotation and external rotation of the air stirrups, etc.)
Take calcium supplements and vitamin D to enhance calcium absorption (under medical supervision)
Control diet not to make continuous weight gain
Prevent fracture to prevent collapse of the bone joint surface
Generally, the following aspects should be done.
To strengthen the awareness of self-protection of the hip
Pay attention to your feet when walking and be careful of falls, especially in winter when walking on snow and ice
Before sports, you should prepare your hip well and feel your body is warm and your limbs are flexible.
Avoid hip sprains when carrying heavy objects and try not to do heavy work
After hip injury, you should treat it in time and not walk too much before the injury is healed to avoid repeated damage to the hip joint.
When treating certain diseases, especially some painful diseases, try not to use hormonal drugs or use them sparingly
Try not to develop a long-term problem of drinking a lot of alcohol
Femoral head necrosis is generally treated by surgical methods and conservative methods, so you must go to a regular hospital.
Surgical methods are the main treatment methods, such as artificial hip replacement, femoral head implant surgery, femoral head drilling and decompression surgery or stem cell transplantation at the same time.
