HIP SCORES & EXPLANATION OF USED TERMS
Find below a table with the different European scores compared with the FCI classsification. Most countries switch to the 'new' FCI system. But on older pedigrees you will find the scores given as below:
|Netherlands (until 2004)||Germany||Switzerland (until 1991)||FCI (all countries)||FCI|
|Frei||A 1||no signs of dysplasia|
|Verdachtig fur HD
|B 1||Transitional Case|
|HD I||B 2|
|HD II||D 1||Moderate|
|HD III||E 1||Severe|
|Positief Optima Forma
|HD IV||E 2|
Now you are able to compare the FCI scores with the OFA scoring
You will find some difference in the upper region.
Bad hips are bad hips everywhere and also indicated the same:
|EXCELLENT||A 1||no signs of dysplasia|
|GOOD||B 1||Transitional Case|
In the Netherlands one is allowed to breed with HD A, HD B and HD C results. We (the Barking Bunch) only breed with HD A and HD B scored BMD's.
note: Hip-classification in numbers 0 to 3 was used in some FCI-countries
until about 1990 (e.g. Switserland) and then changed into classification A to E. So
you can find the older classification still in pedigrees of dogs that were evaluated
before 1990. Grade 1/1 is the same as grade C/C, which means "mildly
displastic". In Switzerland and Germany those dogs are still allowed to be bred. In
our pedigrees you will see these scores as well in the Swiss ancestors.

According to the FCI Scientific Committee the grades are defined ad follows [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).]
Description of classes (A to E), applicable to dogs aged between one and two years, provided correct positioning:
A 1/2: No signs of hip dysplasia
The femural head and the acetabulum are congruent and the acetabular angle according to Norberg (adapted for Pos. 1) is 105° or more. The craniolateral rim appears sharp and slightly rounded. The joint space is narrow and even. In excellent hip joints the craniolateral rim encircles the femoral head somewhat more in laterocaudal direction.
B 1/2: Transitional or borderline hipjoints
The femural head and the acetabulum are slightly incongruent and the acetabular angle according to Norberg adapted for Pos. 1) is 105° or more, or the acetabular angle according to Norberg is less than 105° and the femural head and the acetabulum are congruent.
C 1/2: Mild hip dysplasia
The femoral head and the acetabulum are incongruent, the acetabular angle according to Norberg is more than 100° and/or there is a slightly flattened craniolateral rim. Irregularities or no more than slight signs of osteoarthrotic changes of the margo acetabularis cranialis, caudalis or dorsalis or on the femoral head and neck may be present.
D 1/2: Moderate hip dysplasia
Obvious incongruency between the femoral head and the acetabulum with subluxation. Acetabular angle according to Norberg more than 90° (only as reference). Flattening of the craniolateral rim and/or osteoarthrotic signs.
E 1/2: Severe hip dysplasia
Marked dysplatic changes of the hip joints, such as luxation or distinct subluxation, acetabular angle according to Norberg less than 90°, obvious flattening of the margo acetabularis cranialis, deformation of the femoral head (mushroom shaped, flattening) or other signs of osteoarthrosis.
