I want to get my dog's hips xray'd this spring, do I just have my usual vet do it, or should I seek out a ortho doc, who specializes in bone stuff?
I am not going to OFA her, this is just for diagnostic purposes, for structural health.
And for either doc, is there an optimal position, sedation vs non, and if these optimal recommendations are not followed, can the results end up false positive/negative?
Thanks in advance!

Melissa,
If you're just screening from a health standpoint, I'd feel comfortable with a standard vet.
There is a standard postion for best evaluation of hip joint structure that is used for an OFA xray, but it's pretty much the same view that an office vet would use for general hip evaluation anyway.
Sedation is useful to get a canine to totally relax, and I request it on my dogs for OFA films ( plus....they don't bite the vet, which is a bonus with my beasts <img src="/ubbthreads/images/graemlins/wink.gif" alt="" /> ) but if I was just going for a general screening film, I'd be fine with them being done without the sedation.
The reading/ evaluation of the films is pretty straight forward and can be done by office vets or many experienced breeders. If you want a second opinion from your vet on the x ray, he can send the films to be evaluated by a vet radiologist for an additional fee.

Interesting topic!
The veterinarian I used to work for is considered to be a very knowledgeable guy when it comes to xrays/breeding/repro/etc. When doing hip/elbow xrays for certification he invariably tries to do it without sedation- the reason given being that if a dog is sedated, the joints are too relaxed to give an accurate view. I can probably count on one hand the amount of dogs we had to sedate in the 4 plus years I was there. Personally, I'd avoid drugging a dog if I could help it (just MHO) but if it becomes a safety issue then there's no other option.
What are the opinions of the veterans on this board? Has anyone else heard this viewpoint before?

Corey,
I'm not sure why you'd only want the opinions of ex-military members for this topic...
I mean, Chris D. and I can talk about this...but it'd be kinda boring. <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" />

Corey,
When I had my oldest female's hips xrayed, we did it without sedation, but it was because we pretty much knew that HD and bone spurs were the cause of her pain, and she was able to relax enough to get films to confirm this.
I hadn't planned on sedating her, unless she just won't relax enough to get a picture.

I guess I am looking for a veterinary opinion after all, or at least the educated guess of someone who has been involved with xraying dogs for a long time. Is the idea of a sedated dog's hip joints being too lax for an accurate OFA xray a valid one? It's not an earth-shattering issue, I'm just curious, that's all.

Corey, you ask an excellent question:
"Is the idea of a sedated dog's hip joints being too lax for an accurate OFA xray a valid one?"
I'll venture an educated guess, from a former vet tech's view, along with an example/ comparison of what we do in human medicine ( although I've learned not to compare human and veterinary medicine from past experience, plus I've retired from human medicine ).
I would say that no, a joint that is healthy will not look "lax" on a sedated x ray. The sedation will cause relaxation of muscles but *not* tendons and ligiments. Now, a joint can be manipulated to open the joint space further for a view ( one example - some x ray views of a human shoulder will require the patient standing upright and to hold onto a 5 lb. sand bag to pull the joint a bit apart ) but the manipulation is noted on the x ray film itself, and taken into account by the evaluator.
Also, muscles relax easily. Tendons and ligiments require stretching for change, which is significantly harder.

Hi Will,
Just to add my 2 cents.....the weight bearing shoulder view is done to see( by stressing the joint) whether the weights will show an abnormal seperation in the joint that isn't demonstrated in the routine internal and external rotation view. If the shoulder is normal, you will NOT see a big difference in the joint space. It is only if there is something wrong that one side or the other shows a greater degree of seperation. <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" />
