HIP DYSPLASIA Flashcards
What is hip dysplasia?
-Genetic condition
Can be impacted by environmental factors e.g. obesity
Affects large dogs mostly though can occur in small dogs and cats
What is the cranial draw test
The dogs knee is slightly bent and anterior pressure is applied to the distal four and proximal pressure applied to the proximal tibia
Usually done whilst under anaesthetic or sedation
What is a positive drawer sign of the cranial draw test
Sliding of the distal femur over the proximal tibia. Indicates cranial crucial ligament rupture
What is the bva/kc hip dysplasia scheme?
Radiographs taken of dogs hips (ventro-dorsal view) and are scored. Lower the score the better the hips.
Each breed has a medium, allows breeders to compare and pick dogs to breed from which are below this medium
What is the recommended breeding ages for dogs
Mixed opinion
Males- earlier than females 6-9 months
Females- are at least 1 year and have had first season
KC unlikely to register puppies if mother not between 11months and 8 years
What are the radiographic features of hip dysplasia
Sclerosis- increased bone density
Osteophytes - irregular new bone formation around joints
Remodelling of joint surfaces
Subluxation/ poor coverage of femoral head
What are the main causes of hindlimb lameness
Hindlimb lameness is commonly associated with the stifle (cranial crucial ligament disease) and the hip (hip dysplasia)
Describe the properties of a hip radiograph required for submission to the BVA/KC hip dysplasia scheme
Have to take images in a set position. Need femurs to be aligned and tail to be straight
Needs to have R/L markers, chip number and KC number and date
How can an owner manage hip dysplasia in their dog
- keep weight under control
- supplements
- physio and hydro
- dont breed from them
- dont allow them to jump
- consider surgical treatment if gets worse in future
