I don't believe that OFA is the end all as far as elbows are concerned and would take the word of an OS over OFA everytime.

I will agree with that, because the elbow can be in various degrees of flexation (is that a word ??), and OFA can still give an evaluation.

But the quality/sharpness of the x-ray is VERY important, because of the way the x-rays are read now. Any slight blurring can make it look like there is something going on in the joint. I just can't see how the scanned picture can be as clear as the actual x-ray. They must have one super-duper high powered scanner. lol
