The human thigh bone is the femur, and the most recent end of the femur is the femoral head. Generally speaking, patients with bad femoral head should try to avoid weight-bearing, jumping, sedentary, cross-legged and other actions that put more pressure on the femoral head.
The blood vessels supplying the femoral head and the femoral neck are close to each other, belonging to the end of the blood vessel branches without anastomotic branches or traffic branches. Load bearing, jumping, cross-legged and other actions will easily lead to an increase in the pressure of the femoral head, and the high pressure will squeeze the supplying blood vessels of the femoral head, resulting in ischemia of the femoral head, and the prolonged ischemia may induce the occurrence of ischemic necrosis of the femoral head.
In addition, the femoral head and acetabulum constitute the hip joint, and actions such as weight-bearing, jumping, cross-legged and other actions that put more pressure on the femoral head may cause damage to the ligaments, tendons and muscles around the hip joint, osteophytes and synovial hyperplasia, etc. When the hip joint is in motion, the pressure on the femoral head increases.
When the hip joint movement process, it may lead to abnormal impact between the soft tissues in the joint, accelerate the wear and tear of the joint surface, accelerate the aging of the joint, and even cause the occurrence of osteoarthritis.
