[Prediction of avascular necrosis in the femoral head following fracture dislocation--using the electrochemically generated hydrogen clearance method].
In order to predict necrosis of the femoral head following fracture-dislocation, the blood flow in the femoral heads in twenty-five hips was measured immediately after reduction and three, six, nine and twelve months thereafter. Twenty hips were followed up for more than one year (average 26.3 months) radiographically. Seven out of twenty hips had very low blood flow in the weight bearing areas three months after reduction. Five of seven had very low blood flow six and nine months after reduction and resulted in necrosis which was determined radiographically. The other two of seven recovered the blood flow and have not resulted in necrosis. Thirteen hips with normal blood flow three months after reduction also did not undergo necrosis. It is possible to predict the incidence of necrosis after fracture-dislocation by measuring the blood flow of the femoral head with the electrochemically generated hydrogen clearance method.
