A question about rotation

[Pooka1]

vertebras and ribs do not formed a rigid structure so they should to move together?.. thanks Sharon, but it seems that my imagination is so limited..

I have no idea really but I think you might have a point with older adults who have very stiff spines.

But in my one kid whose rotation was noticeable to anyone and everyone and had a large rib hump, she would need to be in bathing suit and she would have to be standing still and straight and I would have to carefully point out how we can know there is still a slight rotation to someone who isn't familiar with looking for it. They would see it eventually but it is slight.

On radiograph, her two rods are almost superimposed on sagittal view. Almost but not quite because he couldn't (or wouldn't try) to get the last little bit of rotation out. It doesn't matter because he exceeded my expectations given how large her rotation was going in. The surgeon did not promise too much about it so as not to get our expectations up so it is a huge pleasant surprise. He said her case was not straight forward which I think is in reference to correcting this rotation but I really don't know.

She has no rib hump but one shoulder blade still sticks out a bit more than the other. You can see it if she is still and straight, not otherwise.

The other kid, no nothing. She has zero rotation after surgery. Her rods are pretty much superimposed as I recall.

That's just the two cases I have been dealing with. Maybe they are unusual but I doubt it.

Hi junosand...

I think the best way to understand what is done is to view an animation. You can find one here:

Select Thoracic - Derotation with Instrumentation

That's a great site.

I watched the T - derotation w/ instrumentation and laughed at the comment about taking bone from the iliac crest only hurts for a short time. My one friend still has annoying pain at the harvest site more than a decade later. I was prepared to refuse the procedure for my kids based on that.

what also makes me skeptical about what your father thought he remembered is that surgery patients preoperatively are given a drug called Versed that causes retrograde amnesia; i strongly suspect what he thought he remembered was a conscious or subconscious fear he had in his mind before going into the surgery

Junosand, according to Wikipedia (which is by no means necessarily accurate) Versed was first synthesized in 1975. My father's surgery was in 1966 or 1967.

didn't realize it was that long ago; that was before my time
at least in this age, this is not something we need to worry about
