The direct clinical causes of hip pain are: painful diseases such as human labor trauma, strains during training of warrior athletes, rheumatic paralysis diagnosis, and many aseptic inflammatory diseases, where redness, swelling, heat and pain, and joint effusion are already present before developing into osteonecrosis and osteophytes. For many painful diseases, such as aseptic necrosis of bone, various aseptic inflammatory diseases, phlebitis, training fatigue injury, sequelae of long-standing bone injury, periostitis, rheumatoid arthritis, soft tissue injury, fracture not healing to form periostitis, arthritis triggering osteophytes coexist. A period of pain before osteonecrosis is a symptom produced by the onset of soft tissue of osteonecrosis, without painful symptoms, progressive necrosis of bone is not possible, must focus on early clinical symptoms, must rely on radiological examination, focusing on viewing X-rays to identify bone lesions. Should pay attention to the treatment repair healing situation, must also rely on C T, MRI to help diagnose, should be considered together with soft tissue disease, ignoring the important aspect of the causative factors, induced soft tissue disease, resulting in aseptic necrosis of bone.
