超声骨密度测定在诊断婴幼儿早期佝偻病中的应用

Applications of ultrasonic bone mineral density measurement in the diagnosis of early rickets in infants

目的 探讨超声骨密度测定对婴幼儿早期佝偻病的诊断意义.方法 将120例佝偻病患儿和120例健康婴幼儿按年龄分别分为三组,＜1岁组、1～2岁组、＞2岁组,分别行超声骨密度测定,比较不同组别之间的骨密度B超检测Z值和百分比.结果 佝偻病患儿和健康婴幼儿不同年龄组骨密度B超检测Z值和百分比比较差异有统计学意义（P＜0.05）.佝偻病患儿不同年龄组不同性别骨密度B超检测Z值和百分比比较差异无统计学意义（P＞0.05）.结论 骨密度B超检测对婴幼儿佝偻病的诊断具有一定的灵敏度、特异度,且检测手段方便,无痛、无损伤,易于普及推广,对佝偻病的早期诊断、治疗起到积极的作用,值得在临床中推广应用.

Objective To investigate the diagnostic significance of ultrasonic bone mineral density measurement in infant rickets.Methods A total of 120 cases of rickets in children and 120 healthy infants were divided into three groups according to age,〈 1 year group,1-2 years group,〉 2 years group,who were subjected to determination of ultrasonic bone mineral density.The Z value and percentage of bone mineral density via ultrasound detection among different groups were compared.Results There were statistically significant differences in Z value and the percentage between each age group of infant rickets and healthy children according to bone mineral density via ultrasound detection （P 〈 0.05）.No significant differences in Z value and the percentage between each age group of male and female children of infant rickets through ultrasound detection （P 〉0.05）.Conclusions The ultrasonic bone mineral density detection in the diagnosis of infant rickets had advantages of sensitivity,specificity,convenient detection,painless,noninvasive and easy popularization,which plays an active role in the early diagnosis and treatment of rickets,itis worth in clinical application.
