What is hip dysplasia?

Answer 1

Here is a great site that explains all> http://www.thepetcenter.com/xra/hd.html
a hereditary crippling disease of the coxofemoral joint (hip)

Here is an ex ray that shows a normal hip and a dysplastic hip, so you can see the difference > http://www.belfield.com/xray2.jpg

Answer 2

Dysplasia is one of the most prevalent disorders of the canine hip. It is rarely found in dogs less then 11-12 kg, but has been reported in small-breed dogs. The following factors can contribute:
-Genetic predisposition
-Envrionment and dietary factors
-A disparity between muscle mass and the developing skeletal system
-Failure of the soft tissues of the hip to maintain joint congruity between the surfaces of the hip joint, resulting in bony changes within the joint

Most cases of hip displaysia are the "acetabular" form. This type is charaterized by excessive slope of the dorsal rim of the acetabulum and the changes that result. Or in english, the head of the femur isn't fitting into the hip joint correctly. Bone can grow around it and cause it to be unstable and painful.

Dogs with displaysia may have difficultly in rising or lameness, and young dogs that are affected may be reluctant to stand or move.

Conservative treatments for including anti-inflammatory medications and Nutriceuticals, and surgical treatments include a Femoral head ostectomy (FHO), which is when the head of the femur is surgically removed, and the soft tissue surrounding the area makes a "false joint". The other surgical treatments are total hip replacement, and a pelvic osteotomy (provides increased coverage to the head of the femur.)

Dogs intented for breeding should have their hips radiographed after 2 years. Dogs may develop hip dysplasia early in life. Puppies born to hip dysplasia-free parents can develop hip dysplasia. Surgery is the only cure.

Hip dysplasia is a congenital disease that, in its more severe form, can eventually cause crippling lameness and painful arthritis of the joints. It is caused by a combination of genetic and environmental factors. It can be found in many animals and occasionally in humans, but is most commonly associated with dogs, and is not uncommon in many dog breeds, particularly the larger breeds.

Hip dysplasia is one of the most studied veterinary conditions in dogs, and the most common single cause of arthritis of the hips. In humans it occurs at a rate of about 4 births per thousand (0.4%)

Answer 4

Canine hip dysplasia is a developmental orthopedic disease. When a dog has dysplasia, it has an abnormal development of the ball-in-socket joint that makes up the hip. In a dysplastic hip, the ball (the head of the femur, or thighbone) and the socket (the acetabulum, a portion of the pelvis), do not fit together snugly. The result is a painful and damaging friction. When a dog bears its weight on the joint, the friction strains the joint capsule, which is a fibrous tissue that surrounds the joint and produces joint fluid. The straining then damages the cartilage and leads to the release of inflammatory proteins within the joint. Thus begins the cycle of cartilage destruction, inflammation, and pain the symptoms we associate with arthritis.
Among animals with hip dysplasia, the onset of arthritis will vary. Some dogs will get it in early youth; for others, it may not present itself until much later in life. Frequently, two types of hip dysplasia are described: acute and chronic. The acute (early) stage, usually seen in young dogs, is characterized by intense pain in the hips and mild to severe lameness. This stage can last from weeks to months. The chronic (late) stage of hip dysplasia is characterized by pain, decreased range-of-motion in the hips, and progressive arthritis. Chronic dysplasia can develop in dogs less than one year old or it can take many years to occur.
Some dogs will show clear signs of hip dysplasia at a very young age, before the arthritis sets in. For them, a commonly used surgical method is available to prevent its onset. But for many canines, the symptoms will not be obvious until severe, crippling arthritis has developed. At this point, the options for treatment are limited and complex.
Because hip dysplasia is passed on genetically, there is perhaps an even graver consequence of the disease remaining undiscovered: if two dogs with undetected dysplasia are bred together, the painful disease will be perpetuated in the gene pool.
Hip dysplasia is most common among larger breeds of dogs, especially German shepherds, rotweillers, Labrador retrievers, golden retrievers, mastiffs, and Saint Bernards. It can also be seen in smaller breeds such as the cocker spaniel and the springer spaniel; mixed breeds may suffer from it as well.
Clinical Signs:
Decreased activity; difficulty rising; rear limb lameness; reluctance to use stairs, particularly to go up; reluctance to jump or stand on hind limbs; swaggering gait; bunny-hopping gait; pain from manipulation of the hip(s); decreased range-of-motion in the hips; crepitus in the hip joint; positive Ortolani sign; positive Barden’s maneuver; subluxation or complete luxation.
Symptoms:
Less energy and movement; difficulty rising; lameness in the back legs; reluctance to use stairs (particularly to go up); reluctance to jump or stand on hind limbs; swaggering gait, bunny-hopping gait; soreness after lying down; soreness after heavy exercise.
Hip dysplasia can result in a variety of clinical signs. Dogs can have significant hip dysplasia and arthritis and show minimal or no outward signs. Alternatively, hip dysplasia can and frequently does result in crippling arthritis.

Answer 5

Hip Dysplasia is a terrible genetic disease. It is also called degenerative joint disease. The joint is not able to lubricate and block inflammation. They sometimes have trouble with their range of motion. This is a form of arthritis and can cause some dogs to be lame.

Answer 6

Hip dysplasia is common in a lot of breeds. Basset Hounds & daschounds have it due to the fact that their body is longer than their legs. Boxers are common because of their body weight is not dispersed evenly. Some Chinese breeds like ShiTzu & Lhaso Apso get it. It is a congentital problem. Please check with your Vet as there is many ways of preventing and or slowing down the problem.

Dys (ill;bad) + Plasia (growth;development)

Answer 8

Most of the large dog breeds are prone to it ecsprcially german shepard, and alsations, it is when the body gets too heavy for the legs to carry the dog then the hips give in and dislodge which causes severe pain and discomfort to the dog.
It might take an operation to repair, if the damage isn't too severe but unfortunately they are normally euthinased

Answer 9

The German Shepard is prone to that, as far as I can say its a genetic deaise that's similar ti arthritis

Answer 10

.a degenerative bone/joint disorder that plagues purebred dogs this is due to the inbreeding of these animals, i guess it can apply to humans also i have a lot of friends down south with this disorder especially my good friend jethro and come to think of it his dog blue too.
