leg injuries can also cause osteoarthritis, but these injuries are much
less common than hip dysplasia. Fortunately, there are many surgical
and medical treatments for osteoarthritis of the hip.
Hip dysplasia is likely the best known and most common cause of arthritis in dogs. Dysplasia technically means “abnormal development”. Hip dysplasia is therefore the abnormal development of the hip joint. Hip dysplasia in dogs is a genetic disease that can be made worse but is not caused by activity or diet.
Hip dysplasia in young dogs causes pain because it stretches and tears soft tissues. In older dogs it causes pain because of the osteoarthritis that results. Weight control, moderate exercise, and anti-inflammatory medications are the basic methods used to treat hip dysplasia and osteoarthritis.
Surgery for hip dysplasia in young dogs includes triple pelvic osteotomy, femoral head and heck ostectomy, and, in very young dogs, juvenile pubic symphysiodesis.
In mature dogs, surgery includes femoral head and neck ostectomy and total hip replacement.
