摘要
目的探讨超声评价发育性髋脱位（DDH）闭合复位石膏固定术疗效的可行性。方法对闭合复位石膏固定术治疗的73例单侧DDH患儿进行蛙式位髋内侧横切面超声检查，观察股骨头与髋臼的位置关系，并进行相关参数测量，两侧对比了解股骨头复位情况。结果超声检查可以直观显示股骨头轮廓及骨化中心，蛙式位髋内侧横切面可以显示股骨头与髋臼的相对位置关系，判断股骨头是否复位，外移程度及前后移位情况；超声参数测量（股骨头与耻骨联合中心线间距）为复位状态提供量化指标；实时超声动态检测指导复位。结论超声检查简便、直观、无损伤，可视为评价DDH患儿闭合复位石膏固定术疗效的首选影像评价手段。
Objective To discuss the feasibility of ultrasound in evaluating the effect of closed reduction with cast fixation on developmental dislocation of the hip. Methods Seventy-three cases with unilateral DDH treated by closed reduction with cast fixation under frog position were detected by ultrasound on the medial cross-section of the hips. The position relation between femoral head and acetabulum of the hips were demonstrated, the relevant parameters （the vertical distance between the femoral head and the central line through pubic symphysis） were measured and compared with the contra- lateral side to understand the situation of the femoral head. Results The contour of the femoral head and the ossification center can be visually displayed, the relative position relation of the femoral head and acetabulum can be demonstrated on the medial cross-section of the hip under frog position by ultrasound to judge the status of closed reduction. The measurement of the ultrasonic parameters can provide quantitative indicator for the status of reduction. Conclusions Ultrasound can be viewed as the first imaging tool to evaluate the effect of closed reduction with cast fixation on developmental dislocation of the hip for it is simple,intuitive and no radiation injury.
