Stage symptoms of femoral head necrosis?

summary

Avascular necrosis of the femoral head is a common disease in orthopedics department, which is mostly caused by people's bad habits. Moreover, avascular necrosis of the femoral head will lead to paralysis and other diseases. However, avascular necrosis of the femoral head needs symptomatic treatment, especially the treatment methods of each stage of avascular necrosis of the femoral head are different. Let's first introduce the staging symptoms of avascular necrosis of the femoral head?

Stage symptoms of femoral head necrosis?

Progressive pain of knee joint, mild limitation of hip joint activity, X-ray findings, normal appearance of femoral head, slightly blurred cartilage and trabecular bone structure, or spotty osteoporosis, CT, slightly thickened trabecular bone in the middle of femoral head, star like structure, radial or pseudopodia like branches to the cartilage of femoral head, small cystic changes in subchondral area, early concentration of ect, The arterial blood supply was low, MRI showed low signal and abnormal changes.

The X-ray manifestations were subchondral cystic changes, bone tissue destruction and loose interweaving phenomenon. The half moon shaped transparent area in cartilage area was also visible, which was called "crescent sign". Under CT, some bone trabecular sclerosis changes in the bone marrow cavity under the head could be seen. Ect showed a large "hot area" (stagnant blood) or a large "cold area" (ischemia) in the resting phase, and there was a mixed cold and hot intermediate stage, MRI, large low signal area.

Hip and knee pain increased, weight-bearing capacity decreased, lameness. X-ray showed subchondral microfracture, interruption of continuity of some trabeculae, collapse and flattening of the weight-bearing area outside and above the femoral head or bone fragments under the cartilage. CT showed disorder of trabeculae in the femoral head, enlargement of cystic area, bone fragmentation, deformation of the femoral head, hyperplasia and sclerosis of some areas, and bone hyperplasia of the acetabulum. Ect and MRI showed more obvious than stage II.

matters needing attention

To sum up, the above content is about the five stages of osteonecrosis of the femoral head, which can make people better understand the osteonecrosis of the femoral head and treat it in time. People with osteonecrosis of the femoral head should eat more fruits and vegetables instead of spicy food.
