目的探讨超声检测下婴儿股骨头骨化中心出现时间.方法对2010年5月至12月到天津市妇女儿童保健中心进行髋关节筛查、且超声筛查结果为正常的10116例婴幼儿(20232髋)骨化中心显示情况进行统计学分析.结果婴儿年龄为10～226 d,平均年龄(67±0.46)d；其中男婴5531例,女婴4585例.所有超声检查正常的婴儿当中,共有1716例(17.0％)名婴儿双侧股骨头均出现骨化中心,最早出现在1月龄(30d),最晚226天龄仍未出现；骨化巾心集巾出现在2～5月龄(60～179 d)；左右髋差异无统计学意义(P＞0.05).多因素Logistic回归分析显示,骨化中心是否出现与婴儿的年龄、性别、出生体重、出生胎龄、出生身长、目前体重、目前身长、宫内体位、喂养方式有关.结论超声可较早地显示骨化中心,对临床一些疾病的诊断有一定的帮助.

Objective To study the timing of appearance of ossification centers in femur.Methodis Between May 2010 and December 2010,20 232 hips of 10 116 normal infants received hip ultrasound examination for congenital disease screening.The infants' hip ultrasonography was retrospectively analyzed to study the timing of appearance of ossification centers in femur.Results The study recruited 5531 male infants and 4585 females.The infants aged 10-226 days old (mean age,67±0l.46days).Among them,ossification center on both side of femurs were found on 17t6 (17,0％ ) infants.The earliest timing of appearance of the first ossification center was 30 days old,while the latest appearance of the first ossification center was seen on a 226 days old infant.The ossification centers were increasing with aging,and most of the ossification centers appeared between 2 to 5 nonths (60-179days,60.3％).Logistic regression analysis showed that age,sex,birth age,birth weight,birth length,current weight,current length,feeding patterns were risk factors associated with the timing of appearance of ossification centers in femur.Conclusions Uhrasonography is senaitive and accurate to detect the ossification centers in femur.
