摘　　要：目的:应用超声测量骨化率对儿童进行骨龄评估时左、右侧肢体是否一致,以及左、右侧肢体超声骨龄与X射线骨龄的一致性。方法:回顾性纳入2022年10月至2023年11月于贵州医科大学附属医院3~18岁儿童共526例,采用超声测量儿童的左、右侧尺骨、桡骨和股骨的骨化率,计算超声骨龄;同时在超声骨龄检测前后两周内所有受检儿童进行左手X射线骨龄检查。比较使用超声评估骨龄时双侧尺骨、桡骨、股骨的骨化率差异,并进一步对左、右侧超声骨龄和X射线骨龄间的差异进行比较。结果:在超声检测中,左侧尺骨骨化率为48.0%,低于右侧的49.5%,其差异有统计学意义(W=25425.5,P<0.001);左侧股骨骨化率为77.0%,高于右侧的76.0%,其差异有统计学意义(W=57829,P=0.041);左侧尺骨、桡骨和股骨的总骨化率为184.0%,低于右侧的185.0%,其差异有统计学意义(W=46314.5,P<0.001);左侧肢体的超声骨龄为10.1岁,低于右侧的10.3岁,其差异有统计学意义(W=67958.5,P<0.001)。纳入儿童的X射线骨龄中位数为10.2岁,左侧肢体的超声骨龄与X射线骨龄比较,差异无统计学意义(P>0.05)。结论:使用超声检测儿童骨化率评估骨龄时,左右侧肢体存在差异,使用超声评估骨龄时应对左侧和右侧同时进行评估。Objective:To study whether the bone age of the left and right limbs in children was consistent when the ossification ratio was measured by ultrasound,and to compare this consistency between ultrasound bone age of left and right limbs,and the bone age that was determined by X-ray.Method:A total of 526 children aged 3 to 18 years,who were treated at the Affiliated Hospital of Guizhou Medical University from October 2022 to November 2023,were retrospectively included.The ossification ratios of the left and right ulna,radius,and femur of these children were measured by using ultrasound to calculate the bone age of ultrasound.Simultaneously,all children underwent X-ray examination on left-hand for bone age within two weeks before and after the ultrasonic examination for bone age.The differences in ossification ratios of the ulna,radius and femur of dual sides in assessing bone age by using ultrasound were compared,and the differences of assessing bone age among left ultrasound,right ultrasound and X-ray were further compared.Results:In the ultrasound test,Ossification rate of the left ulna was 48.0%,Less than 49.5%on the right side,The difference was statistically significant(W=25425.5,P<0.001),the left femoral ossification rate was 77.0%,Higher than 76.0%on the right side,The difference was statistically significant(W=57829,P=0.041).The overall ossification rate of the left ulna,radius,and femur was 184.0%,Below 185.0%on the right side,The difference was statistically significant(W=46314.5,P<0.001).The ultrasound bone age of the left limb was 10.1 years,Below 10.3 years on the right,The difference was statistically significant(W=67958.5,P<0.001).The median X-ray bone age of the included children was 10.2 years between ultrasound bone age and X-ray bone age(P>0.05).Conclusion:There is difference in the bone age between left and right side of limbs in assessing bone age by using ultrasound to detect ossification ratio.Therefore,the left and right sides should be assessed by using ultrasound to assess bone age.
