There's a reason why you don't see image processing articles written in VB/VB.NET. With the lack of pointer support, it's far more difficult to do imaging processing with any acceptable speed.

That's about all anyone can say because you haven't really asked a question.

I can see massive down-votes of the answers like that these days. However, I voted 5 as this is a reasonable note. Even though its possible to work will LockBits and Dispatcher or WPF WritableBitmap.
You can use the AForge imaging library to do some of the work, but it's still a far cry.

Perhaps from the x-ray, if you have adequate metadata, you would be able to tell the alignment of the image?

The fracture would have to be fairly pronounced for it to show could try a high-pass filter of some sort to get pixels that are > some value towards white.

Here's some info on AForge[^] image processing and some specifically on edge detection[^].
