Abstract:
This paper describes briefly the newest progress in the early diagnosis and prediction of the osteonecrosis of the femoral head (ONFH) after femoral head fracture. It is necessary that early operative intervention and aspiration of the intracapsular blood should be done in order to minimize the occurrence of ONFH. It is wise to avoid positioning the hip in extension and internal rotation until surgery. Traction with hip in flexion is recommended. Using the contrast enhanced (Gd DTPA) MRI with T1 fat saturation imaging within 24 hours after injury, the prediction of ONFH will be possible. It is recommended the ONFH should be divided into two types, namely silent and clinical ones.
