Given surface measurements such as hip breadth and hip depth, how would you predict the location of the femoral head center?

First, from your tags I assume you mean in hummns. Second, are you looking for a formula to get a 3D x,y,z location of the apex? Do you have data on the acetabulum? I don't know of a pure mathematical model, but I can give examples of how it's measured with machines during surgery. –  Atl LED Jan 28 at 2:50
    
Ultimately I want the mean and standard deviation of the x,y,z positions of the rotational center of the femoral head. Was thinking to derive them from survey data of external measurements such as hip circumference since I can't find a published survey of the actual measurements. –  user5530 Jan 30 at 2:57
    
I don't actually think the outer measurements are going to be good predictors, that's why things like MRI's and CT's are done before surgery. Even if you slice it down to group, like African-American adult females or geriatric Caucasian males, your predictions are not going to be accurate enough for medical use. –  Atl LED Jan 30 at 14:56
    
I think you will find this and this good starting points for more reading. Perhaps if you want to take another stab at the question after looking over those, we might be able to answer it here (other than to say you can't). –  Atl LED Jan 30 at 15:02
