Early signs of femoral head necrosis

Early femoral head necrosis may appear precursors include hip pain, hip joint mobility limitation, limp, lower limb weakness, etc. 1, hip pain This is a more common manifestation, pain may be intermittent or persistent, often located in the groin area, inner thigh or hip. Initial pain may be mild, but will gradually increase. Hip joint is the main weight-bearing joint of the human body. When the femoral head is diseased, it will cause pain reaction. 2. Hip joint movement is limited, such as flexion and extension, rotation and other activities will feel inflexible and tight. This is due to the pathological changes of the femoral head affecting the normal function of the hip joint, resulting in decreased mobility. 3. Limp may appear mild limp and feel uncomfortable when walking. This is because of pain or limited joint movement, so that patients unconsciously change walking posture.4, lower limb weakness feeling lower limb strength weakened, easy to fatigue. This is related to the femoral head blood supply affected and hip joint dysfunction. If the above symptoms occur, especially those with related risk factors such as long-term drinking, hormone use, hip trauma history, etc., we should pay close attention to them and seek medical attention in time for detailed examination, such as MRI, so as to make early diagnosis and treatment and prevent further deterioration of the disease. Early detection and intervention are very important for improving prognosis.
