Abstract:
Objective To study the influencing factors and clinical significance of ultrasonic quantitative analysis of the hip-flexion coronal section in the normal infants.Methods Totally 100 normal infants were enrolled.Angle α,angle β and FHC on different positions(mild-flexion and flexion of the hip) were mearured.And angle β on different points(the labrum central and the acetabular tips) were measured.The variation of the measurement index between different positions were analyzed.Results ①There was no significant difference in angle α between the neutral position and hip-flexion position (P ＞0.05).② FHC decreased in the hip-flexion position,and there was significant difference compared with the neutral position (P ＜0.05).③βc were greater than βt in the two positions (P ＜0.05);βc and βt were all greater in hip-flexion position than those in neutral position,the difference was statistically significant (P ＜0.05).Conclusions The results obtained from angle α is stable under the coronal flexion view of the normal infants,and does not vary with changing position.The change of the angle β and FHC with the hip flexion could be used to evaluate the stability of the hip.Measured angle β on the labrum tip has good repeatability.So this point should be selected to measure the angle β.
