Evaluation Of Children With Congenital Dislocation Of The Hip Femoral Hemodynamic Ultrasonic Testing

Objective Congenital dislocated hips in which avascular necrosis developed after closed reduction can be encountered frequently during the treatment. Various position should be responsible for the complication from decrease in total blood flow to the fernoral head. This study was armed to quantit~te hemodynamic flow of medial and lateral circumflex arteries and veins and to evaluate the effect of frog position on blood flow measurements in the hip to assess the capability of Doppler ultrasono raphy to detect ischemic situation Methods 10 congenital hip dislocation (CDH) patients who can be completed t.he correct examination and 10 health children were included in the study, two groups whose average age were 2. 6 and 2. 5 years respectively were performed in frog position and neutral position by standard ultrasound equipment with color and power Doppler capabilities. Results Among all hemodynamic indexes ,variation of pulsatility index value(PI) following the change of position was the most significant in two groups (~<0.r1~01). In CDH group LVV (lateral circumflex vein velocity) showed a marked increase during frog position (p
