【摘要】：目的：初步探讨320排CT容积成像结合软骨视窗技术在测量发育性髋关节脱位（Developmental Dislocation of the Hip,DDH）患儿股骨颈前倾角（Femoral neckanteversion,FNA）中的临床应用价值。方法：收集114例1～8岁DDH患儿320排容积CT扫描图像，将所有髋关节按每一周岁为一年龄段分为1～8岁组，，分别应用常规三维CT测量法及320排CT容积成像结合软骨视窗技术测量每一髋关节的骨性股骨颈前倾角（Bony Femoral neck anteversion,BFNA）及软骨性股骨颈前倾角（Cartilaginous Femoral neck anteversion,CFNA）。①比较每一年龄组两种测量方法测量值的差异。②绘制脱位侧髋关节CFNA值与年龄关系图。③比较单侧DDH患儿脱位侧与未脱位侧髋关节CFNA的差异。结果：①1～5岁DDH患儿每一年龄组CFNA与BFNA均具有统计学显著性差异，CFNA大于BFNA且其差值随年龄增大而逐渐减小，6～8岁DDH患儿每一年龄组CFNA与BFNA均无统计学显著性差异。②1～8岁DDH患儿脱位侧髋关节CFNA经历了由小变大而后又小幅下降的病理变化过程。③单侧DDH患儿脱位侧与未脱位侧CFNA有统计学显著性差异（t=3.161, P=0.003＜0.05），脱位侧CFNA平均值较未脱位侧CFNA平均值大3.98°，双侧CFNA值均大于正常且存在直线相关关系（t=0.354, P=0.021＜0.05）。结论：320排CT容积成像结合软骨视窗技术测量DDH患儿FNA更符合定义，结果准确可信，尤其适用于1～5岁及股骨髁骨骺存在骨化变异的DDH患儿，对FNA的病理变化研究及临床DDH患儿的诊断及治疗有重要意义。
[Abstract]:Objective: to evaluate the clinical application of 320 slice CT volume imaging combined with cartilage window technique in the measurement of developmental Dislocation of the hip dislocation in children with femoral neck anteversion FNA.Methods: 114 cases of children aged 1 to 8 years with DDH 320 were collected. Slice volume CT scan, All hip joints were divided into 1-8 years old group according to the age of one year. Measurement of osteogenic femoral neck anteversion (Bony Femoral neck anteversion1) and chondrogenic femoral neck anteversion (Cartilaginous Femoral neck anteversion1) of each hip joint using conventional 3D CT measurement and 320 slice CT volume imaging combined with cartilage window technique were compared between the two age groups. Methods of measurement. 2 the difference between the CFNA values of the dislocation side of hip joint and the age relation. 3. 3. The difference of CFNA between the dislocation side and the non-dislocation side of the patients with unilateral DDH was compared. Results CFNA and BFNA were found in each age group of DDH children aged 115 years. The difference between CFNA and BFNA in children aged 6 to 8 years old with DDH is not statistically significant. CFNA of dislocation side hip joint in DDH children aged 21 ~ 8 years has experienced from small to large. There were significant differences in CFNA between the dislocation side and the non-dislocation side in the pathological changes with slight decrease. 3 significant difference was found in the CFNA of the dislocation side and the non-dislocation side. The average value of CFNA in the dislocation side was 3.98 掳higher than that in the undislocated side, and the bilateral CFNA value was higher than that in the normal side and there was a straight line. The correlation was 0.354, P < 0.021 < 0.050.Conclusion the measurement of FNA in children with DDH by using CT volume imaging combined with chondrocyte window technique is more suitable for definition. The results were accurate and reliable, especially for children with DDH aged 1 to 5 years old and femoral condyle epiphysis. It is of great significance for the study of pathological changes of FNA and the diagnosis and treatment of clinical DDH children.
