title: [Clinical significance of venous return disturbance in patients with osteonecrosis of femoral head].
abstract: To evaluate the correlation of venous return disturbance (VRD), bone marrow edema (BME) and the amount of joint fluid with clinical symptoms in osteonecrosis of the femoral head (ONFH).
  
  
  
  Twenty patients (25 hips) with ONFH proved by pathology were parallelly examined by 1.5 T MR and medullograph.
  
  
  
  In total 25 hips VRD was observed in 16 hips with medullograph and 13 hips with the clinical symptoms (P <0.05). BME was found in 17 with MRI (P <0.01), and the was found in 15 hips with MRI (Spearman=0.949). VRD were found in 16 hydrarthrus.
  
  
  
  ONFH patients with clinical symptoms have VRD, BME and the hydrarthrus. The medullograph is of value in monitoring the development of ONFH.
