HD-FCI: B 1/2 - Page 1

Regarding the rating HD-FCI: B 1/2

I understand that HD=hip dysplasia rating, and that FCI is the La Fédération Cynologique Internationale

I also understand the rankings from A - E and that B1 indicates mild, but acceptable hip malformation and that B2 is less desireable - oh, and that A is pretty great, indicating no signs of hip displasia.

However, where does the B 1/2 come in and can you direct me to an official reference?

With much thanks,
Marsha

marsha , there iss alot of BS stories about this , let me tell you that I personally have had many dogs eveluated in holland , germany and USU , and came to the following results

same dog got in holland B1/2  got in germany A , got in USA  ofa exelent
same dog got in holland C    , got in germany FASTN   got in USA  ofa good

I did many more with the same results

I must say that evaluating in hollanf(fci rating) changed abit since than , and most dogs that used to be B than, will be rated A now   and so on , so for the dutch FCI ratings there is a certain point from which  to look different
Any B dog from 10 years ago has better hips than todays B dog

Here is an example of B hips
B doesn´t mean dysplatic. Unlike in Holland, it is more difficult to get A in Slovakia then it was in the past.

these hips wouldnot get rated A  in holland

Thanks so much for your responses and it's all quite fascinating. 

I was wondering from where the "1/2" comes.  It appears, at least from the information I could gather that FCI rates A-E and 1-2, so B, B1, B2, A, A1, A2 are "real" ratings according to FCI standards or ratings. 

The closest explanation I could find to the implication of "1/2" was from the Journal of Animal Science, an article titled, "Estimates of genetic parameters for hip and elbow dysplasia in Finnish Rottweilers", stated, "In a borderline joint (B, B1, and B2) the femoral head and the acetabulum are slightly incongruent and the Norberg angle is approximately 105°, or the center of the femoral head lies medial to the dorsal rim of the acetabulum and the femoral head and the acetabulum are congruent." 

I couldn't even find any other references which gave a B rating alone (as opposed to B1, B2, etc.)  My main question is what mandate allows for the "1/2" and from what standards or rankings is it taken and is it an official rating?  I searched for this information for hours and if it is just a implication that the ranking is somewhere between B and B1, then where are the rankings actually accepted, except unofficially?  The primary source of the rankings is at this website and while I found it on the websites of some breeders, I couldn't find it in any articles, papers or official websites.

You are both very kind and patient and I greatly appreciate your taking the time to respond.

Best,
Marsha

I think 1/2 stands for Left/Right.When I was giving info on my dogs there were 3 possibilities how to give info on hips - FCI standard, SV and OFA.With FCI it gives these possibilities A 1/2, B 1/2, C 1/2. What is interesting - on belgian shepherd page you can enter also elbows results while on GSD  page it is not possible.

Wow, that makes perfect sense and clarifies everything for me. 

Thanks so much.

For what it's worth I found on the website http://www.barkingbunch.nl/galerij/hd-title.htm that "The final diagnosis is based on two radiographs, one of them in Position I (with extended hind legs) and the other in Position II (with flexed hindlegs, the frog position."

Thanks,
Marsha

I'm sorry to beat this dead horse, but according to www.savf.org.za/Documents/Hip%20dysplasia%20TV.ppt, you are correct and of 1/2 - 1 is indicative of the left side and 2 is indicative of the right - the source previously posted was from a breeder and the one in this post was from a PowerPoint from the South African Veterinary Foundation.  Personally, I'm more inclined to believe the latter, South Africa being a member of FCI (not that the orignally posted URL isn't from a reliable source - I've really no idea).

Thanks,
Marsha

In the chart below, the FCI seems to subdivide each rating into a better or worse sub group and thats' where the A 1/2 comes from.

With Czech and Slovak A (0/0) would indicate A stamp hips and also (0/0) hips for both right and left hips wiich is the best.....

Unfortunately, many countries have different ways of grading hips and they have so many different scales. Its all so confusing.
