Hello Femoral head necrosis, also known as avascular necrosis of the femoral head, is one of the common osteoarthropathies. Most of them are caused by rheumatism, blood diseases, diving diseases, burns and other diseases, which first destroy the blood of adjacent articular surface tissues**, and then cause necrosis.

The main symptoms are intermittent pain that progresses to persistent pain, followed by muscle spasms caused by pain, limited joint movement, and finally severe disability and claudication. Hormone drugs can also cause the disease. Traditional Chinese medicine believes that the cause of disease is external and internal causes, and the interaction between internal and external factors causes the human body to lose the balance of yin and yang, and the imstancy of qi and blood causes diseases"Condylar paralysis"、"Bone palsy"、"Bone atrophy"。

4" test operation method: the patient lies on his back, one lower limb is straightened, and the other lower limb is placed in the shape of "4" near the knee joint, and one hand is pressed on the knee joint, and the other hand is pressed on the contralateral iliac crest, and both hands are pressed down at the same time.
