subject: Hip Dysplasia A Canine Degenerative Disease [print this page] Hip dysplasia is a condition that manifests itself in humans, dogs and cats. Analyzing the word dysplasia, the word simply means improper growth of the hip. It is when the ball of the hip joint does not fit snugly into the socket, resulting in laxity and excess movement within the joint. Over a period of time there is a gradual loss of the cushioning layer of cartilage, contributing to the development of inflammation. This loss of cartilage and the instability of the hip eventually leads to the formation of arthritis.
In humans, a congenital form of dysplasia can be diagnosed in infants, allowing ample time to correct the misalignment. Breech births sometimes cause dysplasia. Forcing the legs into a protracted, straight position known as hip adduction for long periods of time can also contribute to the formation of hip dysplasia. Genetics seems to play a role in the development of hip dysplasia as parents often had a similar condition. Adult onset of hip dysplasia may occur in the early adult years of the twenties or thirties. Symptoms that may lead to a suspicion of hip dysplasia may be weakness in the leg with the leg occasionally giving out. Limited range of motion is common and there may be a noticeable limp while walking. Pain is a common presentation, originating in the groin and radiating into the gluteal region or the thighs. Upon examination, there may be a marked instability of the hip joint and even a possible dislocation.
Canine hip dysplasia is a similar condition in dogs that can be both painful and crippling. The pain and discomfort is caused by inflammation within the hip joint, which reduces mobility, flexibility and range of motion .They may not exhibit any symptoms at all until the degenerative changes in the form of arthritis, causes inflammation and pain. A dog with hip dysplasia will take longer to arise from a sitting or lying down position. They may be reluctant to play as they once did. Navigating the stairs will take longer and they may whine in pain. Your once active dog may be reluctant to jump and run. While walking, they may have a pronounced sway to their hips. Dogs with hip dysplasia will find a position of comfort, often slouching as they sit or lying with their legs straight out behind them.
Large breeds of dogs such as Golden Retrievers, Boxers, Labrador Retrievers, St. Bernard"s and Bloodhounds are more likely to develop hip dysplasia although smaller breeds of dogs may also be at risk. Diet has been suggested to play a role in the development of hip dysplasia and a leaner diet may prevent or slow the progression of the disease. Weight reduction is important in reducing the stress on the joint and improving mobility. Genetics play a prominent role in the development of hip dysplasia, but just because the parents of the animal were free of hip dysplasia does not guarantee that their offspring will not develop the degenerative disease.
Treatment of hip dysplasia can include the administration of glucosamine, cautious use of aspirin, or even involve a total hip replacement. Acupuncture and chiropractic manipulation have proven to have some success. Gentle exercise is recommended.
With early diagnosis and adequate treatment, dogs with hip dysplasia can enjoy a normal life, with few symptoms.
