目的测量半骨盆在矢状位上旋转移位,为判断骨盆在三维平面上的旋转移位建立基础,从而为骨盆骨折闭合复位提供指导. 方法根据骨盆解剖结构及术前或术中骨盆正位X线影像学资料,建立合理的数学模型,通过影像学特定点、线的测量,计算半骨盆矢状面旋转程度.选取不伴骨性结构异常的尸体骨盆标本10具,用铅线对每具标本双侧髂前上棘及耻骨联合前缘进行标记.模拟矢状位半骨盆旋转移位,摄改良的骨盆正位X线片.使用影像测量软件对影像学资料进行测量与计算,通过统计学分析,验证课题所提出方法的可行性和准确性. 结果测量同一骨盆双侧髂前上棘至同侧耻骨联合前缘的连线距离,左右两侧连线长度差异无统计学意义(P＞0.05).对测量计算得出的旋转侧半骨盆矢状面旋转的角度与实验设计中的20°进行比较,差异无统计学意义(P＞0.05). 结论通过骨盆解剖形态和影像学特征的研究,提出了改良骨盆正位,通过X线片特定点、线的测量计算获得骨盆空间移位的量化指标,能够指导复位操作及复位效果的判断,有助于骨盆骨折移位的闭合复位.

Objective To measure the sagittal rotation displacement of hemipelvis for determining the rotation displacement of pelvis on three dimensional section and further instructing closed reduction of pelvis fractures.Methods Sagittal rotation degree of hemipelvis was calculated by measuring the special radiological points and lines of a rational mathematical model created according to anatomic structure of pelvis and peri-and intra-operative pelvic frontal X-ray view.Ten cadaver pelvises without bony structure abnormality were selected and marked by lead line in bilateral anterior superior iliac spine and exterior edge of pubic symphysis.Hemipelvic rotation displacement in sagittal plane was simulated and modified pelvic frontal view was obtained in X-ray projection.Radiological data was measured and calculated by using radiological measuring software.Thereafter,feasibility and accuracy of the method discussed in the study were verified by statistical analysis.Results Distance of ipsilateral anterior superior iliac spine to exterior edge of ipsilateral pubic symphysis was measured and presented no statistical difference in both sides (P ＞0.05).As compared with the models of 20 degree of rotation of hemipelvis in sagittal plane desgined in this study,the calculated rotation degree presented no significant difference (P ＞ 0.05).Conclusion Quantified indicators of pelvic spatial displacement measured by special points and lines on X-ray films of modified pelvic frontal view put forwarded in study of pelvic anatomic structure and radiographic features guides reduction operation and effect judgment and benefits closed reduction of pelvic fractures.
