[vc_row][vc_column][vc_column_text]Hip dysplasia (HD) is characterized by abnormal formation of the hip joint, resulting in degradation of the cartilage in the joint and leading to damage, inflammation, and pain.

The hip joint is comprised of two main parts, the caput, or head of the femur, which is shaped like a ball, and the acetabulum, a concave socket located in the pelvis. The head fits into the socket and, in unaffected animals, the fit is snug and both parts of the joint are covered in cartilage, allowing for a smooth and wide range of motions.

Hip Dysplasia Gait

A dog standing with its hind legs together to compensate for hip dysplasia.

In animals affected by HD, however, hip joints are loose fitting or misshapen, causing damage to the cartilage through excessive wear and tear, eventually leading to inflammation and pain. While cartilage is continually being replaced by the body, the process is slow and the degradation of the cartilage results in a reduced ability to fix the damage.1[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_separator][/vc_column][/vc_row][vc_row][vc_column][vc_custom_heading text=”Causes” font_container=”tag:h3|text_align:left” google_fonts=”font_family:Droid%20Sans%3Aregular%2C700|font_style:700%20bold%20regular%3A700%3Anormal”][vc_column_text]The cause of hip dysplasia is thought to be a combination of genetics and environment. Though the condition can affect dogs (and some cats) of all breeds or sizes, HD typically affects large-breed dogs, due to their weight, and certain breeds. Breeds more commonly affected by HD include Labrador retrievers, Rottweilers, Newfoundlands, Mastiffs, Bernese Mountain dogs, Boxers, St. Bernards, and Welsh Corgis.2[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_separator][/vc_column][/vc_row][vc_row][vc_column][vc_custom_heading text=”Symptoms” font_container=”tag:h3|text_align:left” google_fonts=”font_family:Droid%20Sans%3Aregular%2C700|font_style:700%20bold%20regular%3A700%3Anormal”][vc_column_text]Symptoms of canine hip dysplasia include abnormal gait (how a dog walks, such as straight or normal versus wobbly or erratic), stiffness, lameness, difficulty when rising from a sitting or resting position, or a reluctance to go up stairs or engage in strenuous activity. Due to the wide range of variation between dogs and daily habits, not all symptoms of HD may be present. Some dogs may also have higher pain tolerances than others, allowing them to cope with the condition, masking its presence.3[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_separator][/vc_column][/vc_row][vc_row][vc_column][vc_custom_heading text=”Diagnosis” font_container=”tag:h3|text_align:left” google_fonts=”font_family:Droid%20Sans%3Aregular%2C700|font_style:700%20bold%20regular%3A700%3Anormal”][vc_column_text]Diagnosis of hip dysplasia is generally done through x-rays and radiographs, along with physical examinations. X-rays are important in determining the state of the joint and the level of cartilage damage, if any, present. Other conditions that can mimic symptoms of HD include lower back problems, torn ligaments, or elbow dysplasia.3[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_separator][/vc_column][/vc_row][vc_row][vc_column][vc_custom_heading text=”Treatment” font_container=”tag:h3|text_align:left” google_fonts=”font_family:Droid%20Sans%3Aregular%2C700|font_style:700%20bold%20regular%3A700%3Anormal”][vc_column_text]Methods of treatment for hip dysplasia include both surgical and non-surgical means, depending on how far the disease has progressed. In early or less-severe cases, non-surgical methods can be enough to alleviate or even prevent further progression of HD. Three important factors in non-surgical treatment are weight, exercise, and medication.

Weight control is considered the most important factor in preventing HD. Excessive weight contributes unnecessary force on hip joints, leading to increased joint damage. This is generally why large breed dogs are more susceptible to the condition than smaller dogs.

Reasonable exercise can be beneficial in promoting cartilage growth and prevent muscle loss in the hind legs, though excessively long running sessions or jumping should be avoided.

Pain medication and anti-inflammatories can be used to alleviate pain and discomfort and prevent damage from inflammation. Supplements can also be used to promote cartilage growth and repair. Mobility devices such as harnesses or carts can also help to reduce stress and pressure on joints and can be used in conjunction with other methods.

In more severe cases of HD, surgery may be the only option, including hip repair or full hip replacement.4[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_separator][/vc_column][/vc_row][vc_row][vc_column][vc_custom_heading text=”Canine Hip Dysplasia Statistics5” font_container=”tag:h3|text_align:left” google_fonts=”font_family:Droid%20Sans%3Aregular%2C700|font_style:700%20bold%20regular%3A700%3Anormal”][vc_column_text]Below are statistics of hip dysplasia in dogs from the Orthopedic Foundation for Animals between January 1974 through December 2013.[/vc_column_text][vc_tta_accordion active_section=”9″][vc_tta_section title=”Reveal Breed Statistics” tab_id=”1476385874693-f1ce91e3-1c13d2cf-6134″][vc_column_text]
