With hip pain, people are usually alert to whether it is femoral head necrosis. But what is the cause of hip pain after MRI has ruled out osteonecrosis of the femoral head?
Of course, there may not be any lesion per se, and one should consider whether the pain is related to exertion and exercise. In addition, mild hip dysplasia, femoral acetabular impingement syndrome and other diseases have some special signs on X-ray that are not easily detectable without the typical changes of femoral head necrosis.
