To study the application value of high frequency ultrasonography in the diagnosis of neonatal clavicular fracture
摘要
Abstract
Objetive To study the application value of high frequency ultrasonography in the diagnosis of neonatal clavicular fracture, dynamic observation of healing process and evaluation of the effect. Methods We used high frequency ultrasound technique to screen the neonatal clavicular fractur who had clavicular fractures risk factors. If they had any contiguous bony cortex interrupt, a hypoechoic or anechoic areas and other abnormal sonogram, we thought of them as neonatal clavicular fracture, and then took X-ray examination as the gold standard,and then we compared the two examination methods. After 10 days and 20 days,the neonates who had Clavicular fractures were took to have the second and third high frequency ultrasound examination of bilateral subclavian, and we compared the clavicular fractur healing bone callus sonograms with the normal clavicular sonograms. Results There were 106 cases of neonatal clavicular fracture who had completed the study. In the first high frequency ultrasonic examination, 103 cases were positive and 3 cases were negative , the sensitivity was 97. 2% and the specificity was 100% . The positive rate of the high frequency ultrasonic and X-vay examination was no significant difference (P =0. 083) . In the process of fracture healing, bone callus sonograms were presented funicular low strong echo in the calluses marginal cortical bone, and the sonograms of the middle part of the medullary cavity of calluses were presented no echo areas or low echo areas, some spots of low strong echo were scattered in the areas, the echo intensity was same as the callus marginal cortical bone strength at the same time. The marginal bone cortex Of callus was gradually thickening with the process of callus growth healing , the numbers of spot intermediate echo were gradually increased and the echo intensity was increases gradually at the same time. Conclusions The high frequency ultrasound technology has the advantage that is reliable, without damage of X ray in the screening diagnosis of neonatal clavicular fractures. It has a big advantage especially in dynamic observation of healing process on the neonatal clavicle frac-ture and efficacy assessment. It is worthy of popularization and application.关键词
