Naomi,

You are right the coverage is very good, someone else might know more and I really am not sure about this but I think where the reports talks about the acetubular margins means there is a gap between the hip socket and the ball of the femur. My DD's report says "there is mild rounding of both acetabular margins with app 50% femoral head coverage" and I know the radiographer talked about a gap.

In most cases the coverage is the important part and once the covereage is around 70% means kids start to come out of whatever brace they are in, so not really sure what it all means for you.

I know it will be a long wait till your Dr app. but just enjoy your baby without any brace/harness while you can.

Edit - Naomi I was just looking online at a definition of acetabular and found there is form of hip dysplasia called acetabular dysplasia perhaps this is what the issue with Bailey's hips
