ABSTRACT
Objective To investigate the value of prenatally quantitative sonography in diagnosing clubfoot.Methods By routine sonography totally 32 feet diagnosed doubtfully with clubfoot were chosen as case group,and 414 normal feet between 16 and 38 weeks'gestation were enrolled in control group stochastically.The length of foot(FL)and width of the foot(FW)in both group were measured,and then the length-to-width ratio(FL、FW)was calculated.On the basis of the research of Glotzbecker,the angle that the long-axis of the foot made with the long-axis of the lower leg was measured and classified into mild, moderate,severe degree in control group.The length and width of the foot and the length-to-width ratio in both groups were compared.After birth,the fetuses of case group were followed up and Dimeglio score was recorded.The FL、FW and the angle that the long-axis of the foot made with the long-axis of the lower leg were subjected to the correlation analysis with Dimeglio score,respectively.Results Twenty-six of the 32 feet with prenatal diagnosis had a clubfoot documented at birth(false positive equals to 18.8%).According to Glotzbecker's classification,13,13 and 5 of 32 feet respectively were classified as mild,moderate,severe degree.The FL and FL、FW in case group were smaller than those in the other group(FLZ=-2.10,P <0.05;FL、FWZ=-8.46,P <0.001),and the foot width was wider(Z=-2.06,P <0.05).Significant negative correlation was identified between the FL、FW and the Dimeglio score(r =-0.600,P <0.01) and significant positive correlation was identified between the angle that the long-axis of the foot made with the long-axis of the lower leg and the Dimeglio score(r=0.764,P <0.01).Conclusions The angle that the long-axis of the foot made with the long-axis of the lower leg,FL,FW and FL、FW can provide more information for prenatally sonography in diagnosing clubfoot without more section of the examination.
