Normal values of space in front of the femoral neck at different age of normal children and their clinical significance / 中华超声影像学杂志

ABSTRACT

Objective To measure the width of space in front of the femoral neck at different age of normal children for diagnosis such as hip disease in children as bilateral transient synovitis of the hip. Methods Four hundred and twenty normal children below 14 years old were divided into 14 groups according to their age. Every group contained 30 children. They underwent bilateral ultrasonographic assessment. The width of space in front of the femoral neck was measured and collected. The mean width value in each group was compared mutually by statistical analysis (t test). Results The mean width of space in front of the femoral neck of normal children below 14 years old was 2.0 - 5.9 mm, the range was 1.2 - 7.8 mm. Conclusions The width of space in front of the femoral neck is different at different age of normal children, the mean value below 14 years old
