What reason does femoral head ache

summary

Femoral head pain is a very common disease in modern society, now many people feel their femur pain, but those who know it should be very familiar with it, but they don't know why. There are many causes of femoral head pain, among which the most harmful is femoral head necrosis. Moreover, because many people do not understand the causes of femoral pain, they begin to treat blindly, which will aggravate their condition. So, what is the cause of femoral pain?

What reason does femoral head ache

First, the main intraosseous factors are as follows: after necrosis of the femoral head, trabecular bone structure is destroyed, microcirculation is compressed, blood supply is obstructed, arterial blood supply is insufficient, venous blood flow is stagnated, resulting in increased intraosseous pressure, stimulating cartilage and synovium of the femoral head to cause pain; necrotic bone tissue releases an enzyme protein to produce toxin, stimulating synovium and joint capsule to cause pain; The femoral head collapses and deforms, the joint surface is uneven, and loses the normal load-bearing function. It stimulates the periosteum to cause pain under the normal stress.

Second, the causes of femoral pain are more complex: after the necrosis of the femoral head, trabecular bone structure is destroyed, and the load-bearing function is decreased, which can aggravate the pain. After necrosis, the stress of both hips was uneven, the joint function was unbalanced, and the pelvis was tilted, resulting in contracture of muscles, ligaments, tendons and joint capsule, causing pain; When the hip joint has pathological changes, it can stimulate the nerve. Through the spinal reflex, pain will appear in the inner thigh and knee. The wind, cold, heat, dampness and dryness outside have an impact on the human body and the changes of symptoms, which will aggravate the pain.

Third: under normal circumstances, the cause of femoral pain belongs to the symptoms of femoral head necrosis, because the pain is uncertain, femoral head necrosis is not necessarily femoral head pain, early mainly with knee pain, leg pain, so it is difficult to diagnose.

matters needing attention

This kind of pain will continue to develop, the final site of pain is necrosis of the femoral head. If we don't do our best to treat it, the pain will not be relieved and will continue to develop.
