Objective:To study the diagnostic value of gray scale ultrasound and color Doppler flow imaging in the clinical staging of transient synovitis of the hip(TSH)in children.Methods:A total of 80 children with TSH were selected,and all were unilateral TSH.The healthy side was selected as the control group.According to the duration of illness,symptoms,signs and imaging results,the dis-ease was divided into Ⅰ-Ⅳ stages.The anterior cervical space,synovial thickness and color Doppler flow grading were measured,and the correlation between these indicators and clinical stages was analyzed.Results:The anterior cervical space and color Doppler flow grading of the affected side were higher than those of the healthy side(P<0.05).There was a significant positive correlation between anterior cervical space,hip joint cavity effusion,color Doppler flow grading and the clinical stage(P<0.05).Stepwise regression analy-sis showed that the risk factors for clinical staging of TSH were age,duration of illness,and color Doppler flow grading of the affected side.Conclusion:Gray scale ultrasound and color Doppler flow grading can provide imaging indicators for TSH in children.Color Dop-pler ultrasound flow imaging can reflect the micro blood flow in the thickened synovium of the hip joint,which has important value in diag-nosing TSH in children and its clinical staging.
