摘　　要：目的通过ＣＴ测量，建立国内成人髋臼断面角的正常值标准。方法对１２０例因腹部或盆腔病变行ＣＴ检查而无髋部症状的病人加扫双侧髋关节。从中挑选Ｘ线和ＣＴ表现正常的１００例作为统计对象。结果成年男性被研究者髋臼前断面角（ＡＡＳＡ）的范围为５９．００°～８３．００°，平均值为７２．５６°，标准差为５．６１°；髋臼后断面角（ＰＡＳＡ）的范围为８４．００°～１１６．００°，平均值为１００．６２°，标准差为５．７６°。成年女性研究者ＡＡＳＡ的范围为５３．００°～９２．００°，平均值为７０．４５°，标准差为７．７９°；ＰＡＳＡ范围８７．００°～１２０．００°，平均值为１０３．６６°，标准差为７．２２°。结论国内正常成年男性ＡＡＳＡ正常值范围为６１．５６°～８３．５６°，ＰＡＳＡ为８９．３３°～１１１．９１°，成年女性ＡＡＳＡ为５５．１８°～８５．７２°，ＰＡＳＡ为８９．５１°～１１７．Objective To establish the normal values of the acetabular sector angles. Methods CT scanning of hip joints was done in 120 patients who had abdominal or pelvic CT examinations.From them, 100 cases with completely normal Xray and CT manifestations of both hip joints were chosen as the candidates for this statistical analysis.Mean value plus and minus 1.96 SD(Standard deviation) in the central slice (equatorial plane ) of femoral head was defined as normal value. Results On equatorial plane, the range, mean value and SD of anterior acetabular sector angle( AASA ) were 59.00-83.00, 72. 56 and 5.61in male adults and 53.00-92.00, 70.45 and 7. 79 in female adults whereas those of posterior acetabular sector angle(PASA) were 84.00-116.00, 100.62 and 5.76 in man and 87.00-120.00, 103.66 and 7. 22 in wome,respectively. Conclusions Normal value limitation of AASA and PASA is 61.56-83.56 and 89.33-111.91 in Chinese male adults and 55.18-85.72 and 89.51-117.81 in Chinese female adults.
