Hip Dysplasia
It is a congenital disorder with a hereditary component. Heredity deals with several genes and causes an abnormal development of the joint between the femur and pelvis. It is a latent defect which should be diagnosed 30 days after the maximum delivery. It is present in all breeds of dogs, and even in cats but the large breeds of dogs are the most concerned. Currently the eradication of disease is ongoing with a systematic radiological monitoring of breeding and allowing classification does not take puppies whose parents are achieved.
Symptoms are present in two phases :
- First phase : The end of growth puppy wrong and an approach “rolling”, it may even limp. He does not jump or stretch.
- second phase : The dog now near 3 years and in addition to the symptoms he had from his youth, he now badly when the handles.
For radiography is valid and interpretable, it must be done according to a specific standard. The dog is anesthetized, placed on the back, the hind limbs in extension and slight rotation. The bearings are placed at the zenith.
Then, interpretation is classifying dysplasia in 4 stages :
- Stadium 1 : Primer of a defect of coaptation between the acetabulum and the femoral head Inadequate contact or a lack of depth of the acetabulum (pelvic cavity for accommodating the femoral head)
- Stadium 2 : Default more pronounced and onset of secondary lesions A stadium 1 even more pronounced
- Stadium 3 : Marked subluxation of the acetabulum and the femoral head Here it is clear that the head of the femur will only fit partially into the cavity of the pelvis.
- Stadium 4 : Dislocation of the femoral head The head is not at all in the pelvic cavity.
The treatment will aim to reduce the pain and reduce the dislocation.
- For the pain, painkillers and surgery can be used.
- For reduce dislocation, surgery is the only solution. The choice of operation is based on your pet, the veterinarian will tell you what operation is suitable for him.
