Dysplasie de la Hanche
La dysplasie de la hanche est une condition génétique courante.
Hip dysplasia is a developmental condition where the hip joint doesn't form properly, leading to looseness, pain, and eventually arthritis. It's one of the most common orthopedic conditions in dogs, particularly in large and giant breeds. Early detection and management can significantly improve outcomes.
Points Clés
- Genetic condition — certain breeds are predisposed
- Large and giant breeds are most commonly affected
- Signs often appear in young dogs (5-12 months)
- Weight management is critical
- Surgery may be needed in severe cases
- Responsible breeding reduces the incidence
Understanding Hip Dysplasia
In a normal hip, the ball of the femur fits snugly into the hip socket. In hip dysplasia, the socket is too shallow or the ligaments are too loose, allowing the ball to slip partially or fully out of the socket. This causes abnormal wear, cartilage damage, and eventually painful arthritis. It's hereditary but influenced by environmental factors (rapid growth, obesity, overexercise in young dogs).
Breeds at Risk
German Shepherds, Labrador Retrievers, Golden Retrievers, Rottweilers, Bulldogs, Great Danes, Saint Bernards, and many other large breeds are predisposed. However, hip dysplasia can occur in any breed, including small dogs. Dogs should ideally have their hips screened before breeding (PennHIP or OFA evaluation).
Signs and Diagnosis
In young dogs: difficulty rising, 'bunny hopping' gait (both back legs moving together), reluctance to exercise, and hind-end lameness. In older dogs: chronic hind leg lameness, difficulty with stairs, muscle wasting in the thighs, and pain when the hips are extended. Diagnosis is confirmed with X-rays under sedation.
Treatment
Conservative: weight management (critical), controlled exercise, joint supplements, NSAIDs, physical therapy, and hydrotherapy. Surgical: for young dogs, JPS (juvenile pubic symphysiodesis) can redirect hip growth. For adults, TPO (triple pelvic osteotomy) or total hip replacement may be recommended. FHO (femoral head ostectomy) is an option for smaller dogs.
