Because it's is unreadable on the picture below, here is what is said, in English, for each category:

A.  No signs of hip dysplasia – A. the femoral head and the acetabulum are congruent.  The craniolateral rim appears sharp and slightly rounded.  The joint space is narrow and even.  The acetabular angle according to Norberg (adapted for Pos. 1) is about 105 degrees (as a reference).  In excellent hip joints the craniolateral rim encircles the femoral head somewhat more in laterocaudal direction.

B.  Near normal hip joints – B. the femoral head and the acetabulum are slightly incongruent and the acetabular angle according to Norberg (adapted for Pos. 1) is about 10 degrees or the centre of the femoral head lies medial to the dorsal rim of the acetabulum and the femoral head and the acetabulum are congruent

C.  Mild hip dysplasia – C. The femoral head and the acetabulum are incongruent, the acetabular angle according to Norberg is about 100 degrees and/or there is a slightly flattened cranilateral rim.  Irregularities or no more than slight signs of osteoarthrotic changes in the margo acetabularis cranialis caudalis or dorsalis or on the femoral head and neck may be present.

D. Moderate hip dysplasia – D. Obvious incongruency between the femoral head and the acetabulum with subluxation.  Acetabular angle according to Norberg more than 90 degrees (only as a reference).  Flattening of the cranilateral rim and/or osteoarthrotic signs.

E.  Severe hip dysplasia – E. Marked dysplastic changes of the hip joints, such as luxation or distinc subluxation, acetabular angle according to Norberg less than 90 degrees, obvious flattening of the margo acetabularis cranialis, deformation of the femoral head (mushroom shaped, flattening) or other signs of osteoarthrosis.
