Serra de Itanhandu Kennel has a rigorous control and its whole breeding stock is
HD-free.


About displasy: It is a genetic disease that affects Brasilian Fila, causing pain and
suffering to dogs.


F.C.I. NORMS TO EVALUATE COXOFEMORAL DYSPLASIA

HD- No signs of coxofemoral dysplasia  Allowed to breed
HD+/- Coxofemoral joints near to normality  Allowed to breed
HD+ Mild coxofemoral dysplasia  Still allowed to breed
HD++ Moderate coxofemoral dysplasia  Not allowed to breed
HD+++ Severe coxofemoral dysplasia  Not allowed to breed

(HD-) No Signs of Dysplasia

- Femoral head and acetabulum are congruent and acetabular angle in relation to Norberg   is of 105
degrees or higher;
- Craniodorsal rim is clear and slightly rounded;
- Joint space is narrow and uniform;
- Coxofemoral joints are excellent and craniodorsal rim surrounds femoral head, something   towards
dorsocaudal;
Note: Femoral head center must be medial in relation to dorsal acetabular rim or at least   tangent

.
(HD+/-) Coxofemoral Joints Near to Normality

- Femoral head and acetabulum are slightly congruent and acetabular angle in relation to   Norberg is of
105 degrees or higher;
- Or, acetabular angle in relation to Norberg is lower than 105 degrees and femoral head   and
acetabulum are congruent;
- Minor irregularities in the dorsal or caudal acetabular rims might be present.


(HD+) Mild Coxofemoral Dysplasia

- Femoral head and acetabulum are congruent;
- Acetabular angle in relation to Norberg is higher than 100 degrees and/or craniodorsal   rim is slightly
flattened;
- Mild signs of osteoarthrosis, altering dorsal, caudal or cranial acetabular rim.


(HD++) Moderate Coxofemoral Dysplasia

- Obvious (clear) congruence between femoral head and acetabulum with subluxation;
- Acetabular angle in relation to Norberg is higher than 90 degrees (only as a reference);
- Craniodorsal rim flattened and/or osteoarthrosis signs.


(HD+++) Severe Coxofemoral Dysplasia

- Pronounced dysplastic changes in coxofemoral joints, as well as luxation or clear   subluxation;
- Acetabular angle in relation to Norberg is lower than 90 degrees;
- Obvious flattened of cranial acetabular rim ;
- Femoral head deformation (mushroom shape, flattened) or other signs of osteoporosis.
