I've never heard of them (not particularly important, but it should indicate to you that their results aren't especially wide reaching).
You don't need anymore than average 3D/spatial skills to be a surgeon. Please don't discount a particular career based on these results. After all, becoming a surgeon is more than just technical skill.
The conventional wisdom holds here: apply to medical school and when you find something that interests you (it may not be surgery), pursue it.
On that note, moving to Pre-med forum.
