Will she grow out of it?

Asking for an internet challenged friend. (not sure if this is the right forum but I figure you guys know the most about growing babies)

A while ago my friend upgraded/rescued a weanling filly, best guess is throughbred or a TWH cross. She's supper leggy with no barrel at all. No other knowledge.

Anyways, she looked normal enough a year ago (after she gained a bit of weight) But then she started growing odd and since she's not growing out of it we're getting worried about her hind legs.

ATM she's got these super long gaskins and to compensate she stands either waaay camped out with her pelvis/back tilted or with the worst sickle hocks ever. Her croup is still mostly even with her withers. It's like she should be butt high, but refuses to stand like that. (totally that kind of attitude) As of now she's a year and a half (best guess)

What we're wondering: Is this going to affect her joints when she grows up? Is this conformation indicative of what she's going to look like? Is there anything she can do to help her if she's going to end up with these funky hind legs? (Started taking her for walks on the asphault as per vets advice)

The weirdest part is that she's staying that way, not growing out of it at all. (I've seen QHs do weird growth spurts, nothing like this reedy little gal)

No pictures, you'll have to imagine. Sorry I'll try to get some next week when I see her

Im not sure, hard to see without the pics, but if she has long gaskins it will affect her movement. But as I said it is hard to imagine really. If it is a conformation fault she will be born with it and not grow into the bad conformation if that makes sense. So I would contact a vet

I lost my friggin camera XD

Anyways, for those who are interested, she did ask a different vet for his opinion. Turns out she was right to be nervous about asking- he laughed at her (well, chuckled in a kindly old-country-vet way) and told her the filly is most definitely a saddlebred or part saddlebred, and that some grow out of it, some don't.

I thought the wonky neck was just an underfed yearling thing. After looking at pictures of saddlebreds I don't know how we thought she was anything else.
