Lameness is one of the clinical manifestations of femoral head necrosis, and there are many reasons for lameness, such as; Hip sprain, pelvic tilt, spinal deformity, muscle spasm or weakness, psychological factors, etc. Lameness is not a patent for femoral head necrosis.
The main cause of early necrotizing claudication of femoral head is pain, that is, the step of letting go of pain. As soon as the patient's foot hits the ground, the pain will recover immediately, so he will limp on tiptoe when walking. Necrosis of the femoral head developed to the late stage, and the affected limb was shortened due to the large area collapse of the femoral head. When the leg touches the ground, the pelvis descends, which leads to the ipsilateral shoulder inclining and sinking, the hip and knee of the contralateral swinging leg are excessively flexed, the ankle back is extended, and the inclined shoulder steps appear. Lameness is one of the symptoms of femoral head necrosis, and there are different reasons for lameness in different periods of femoral head necrosis.
Warmly remind the majority of patients that limping should not be taken lightly. If the duration of lameness exceeds 1 month, the patient should go to a regular hospital for examination, so as not to delay the best period of treatment of femoral head necrosis.
