![]() ![]() In turn, laxity leads simultaneously to subluxation, inflammation, and periarticular new bone formation. Polygenic and environmental factors contribute in a complex manner to cause laxity via morphologic changes such as joint incongruity or abnormal pelvic musculature, joint capsule, or round ligament. While various etiologies have been proposed, it is generally accepted that coxofemoral joint laxity is a principle component of hip dysplasia at an early stage. Simplistically, the pathophysiology of hip dysplasia can be described as joint laxity leading to degenerative joint disease. Screening for hip dysplasia in young dogs is important for treating affected individuals as well as for making breeding recommendations for owners. The etiology is multifactorial, having both genetic and environmental components. Large breed dogs are most commonly diagnosed, however small breed dogs and cats also are affected. First described in the 1930's, it continues to affect millions of dogs worldwide. Other treatment modalities are laser therapy, physical therapy, water treadmill, and acupuncture.Hip dysplasia is the most common developmental orthopedic disease in dogs. Most cases will need pain meds, anti-inflammatory drugs, and glucosamine. On the other hand, the dog with a severely arthritic hip may be helped only by surgery to implant an artificial hip. Especially in small to medium dogs, another effective surgical option is an FHO (femoral head ostectomy) where the head of the femur is removed. Some young dogs may be helped by a surgery called a triple pelvic osteotomy (TPO). ![]() Treatment for hip dysplasia depends on the severity of the disease, the age of the dog, and what expense the owner is willing to incur. DLS is a new system recently developed by Cornell University. OFA will evaluate your dog at any age, but the dog needs to be at least 24 months of age to be certified. People who want to breed their dog often do this if you breed two dogs with good hips you are more likely to get puppies with good hips. With OFA and Penn-Hip you can also send the hip films to a radiologist for an official evaluation and certification. These are just different methods of positioning and measuring. There are three methods of getting the hip x-rays: OFA, Penn-Hip, and DLS. Dogs classified as severely dysplastic have a full separation of the femur from the hip socket which leads to severe arthritis.ĭiagnosing hip dysplasia requires x-rays of the hips this almost always requires sedation or anesthesia for proper positioning. Dogs with moderate dysplasia will have more separation, which causes wear and tear leading to degenerative arthritis. Dogs with mild dysplasia have a mild separation between the ball and hip socket. ![]() In a normal hip joint, the head of the femur (thigh bone) fits snugly into the socket. Hip dysplasia is not an “all or nothing” condition, but occurs on a spectrum determined by the amount of hip dysfunction. These symptoms include pain when walking, a swaying gait or limp, “bunny hopping” when running, and, most commonly, difficulty getting up due to pain in the hindquarters. The earliest symptoms can occur between four months and one year, although the signs may not be apparent until the dog is middle-aged or older. ![]() Studies have shown that feeding a puppy too much of a high-calorie diet can cause the puppy to grow too quickly, which then increases the risk for hip problems. Hip dysplasia is caused primarily by genetics, although other factors also play a role. With hip dysplasia being a common condition in dogs, it is important that dog owners understand the symptoms, causes and treatment options. This condition affects male and female dogs equally. The condition can occur in small and medium sized dogs as well, for instance, the Cavalier King Charles Spaniel, Pug, and the Sussex and Clumber Spaniel. On the other hand, hip dysplasia is uncommon in the Doberman, Great Dane, and Greyhound. Hip dysplasia is most prevalent in larger breed dogs, especially German Shepherds, Golden Retrievers, Labradors, Saint Bernards and Rottweilers. Canine hip dysplasia is the abnormal formation of the hip joint and one of the leading causes of rear leg lameness in dogs. ![]()
