Hip Replacement Isn't Only Option to Treat Osteoarthritis Pain

Dear Doctor: I'm 55 years old and a former marathon runner. Now my right hip hurts all the time, not only when I walk but also when I'm lying down. I can't even sleep on my right side any more. I was told I need a hip replacement. What does that entail?

Dear Reader: You've described several of the signs and symptoms that make discussing the option of a hip replacement with your doctor a good idea. The goal of the procedure is to address chronic hip pain, increase mobility, return patients to normal activities and restore quality of life. But before you go booking an O.R., let's talk about the operation, as well as possible alternatives.

Hip replacement is a surgical procedure that replaces the diseased or damaged portions of the hip joint with an artificial joint, known as the prosthesis. An estimated 332,000 individuals undergo hip replacement surgery in the United States each year. The surgery is most common among people with osteoarthritis, a degenerative disease that causes joint cartilage to wear away over time. The hip joint becomes rough and ragged, and the ensuing friction causes both pain and stiffness. Rheumatoid arthritis, injury and fractures can also cause sufficient damage to merit a full replacement of the hip joint.

After documenting your symptoms, your doctor will order imaging tests, beginning with an X-ray, to get a detailed image of your hip joint. He or she will be looking for changes to the bone, signs of narrowing of the joint space and the formation of bone spurs. In some cases, an MRI or a CT scan may be ordered as well.

Before focusing on hip replacement as a solution, we help our patients explore other options for dealing with the pain and lack of mobility. These include physical therapy, walking aids, cortisone shots or medications, and pain and/or anti-inflammatory medications. Some people try supplements like glucosamine and chondroitin for pain relief. These and any other nutritional or herbal supplements should always be reported to your physician to guard against possible drug interactions.

Hip replacement surgery takes about one to two hours to perform. An orthopedic surgeon removes the diseased and damaged bone and cartilage and an artificial hip is implanted in its place. A prosthetic socket is implanted into the pelvic bone, and a prosthetic ball replaces the rounded top of the femur. Patients are often surprised when they're asked to sit up and even take a few steps with a walker the day after surgery, which is to deal with the increased risk of blood clots.

After the surgery, patients must work with a physical therapist to rehabilitate the hip. They are given stretching, flexing and strengthening exercises, which they must continue to do on their own to assure the best recovery and results. They must also watch for potential complications like blood clots, infection, dislocation and a discrepancy in leg length.

Full recovery after hip replacement surgery takes three to six months. For the best chance of success, be scrupulous about rehab, and don't try to do too much.

Advance Directives Imperative to Patients, Doctors and Families

Dear Doctor: I am a 60-year-old man who exercises regularly and takes no medicines. At my last physical exam, my doctor gave me an advance directive form. Do I really need to fill one out?

Dear Reader: Unequivocally, yes. Advance directives are forms providing direction to both family members and the medical community about your wishes in emergencies. More to the point, they specify what your wishes are, in case you can't speak for yourself.

The first part of an advance directive asks whom you would want to make medical decisions for you. Termed a medical power of attorney, this can be your wife, one of your children or a very good friend. It cannot be your doctor. The crucial aspect of this choice is the level of trust you have in your decision maker. If you were to lose decision-making capacity, this person would speak with doctors about your care on your behalf -- becoming both your advocate and the person who chooses resuscitative measures, if any. Not only should you trust the person to whom you give medical power of attorney, you also need to have frank conversations with that person about what you would want.

It sounds as if you're healthy, and thus have a low likelihood of a major illness. But health problems can happen at any time. If you were hospitalized for a heart attack, stroke or a traumatic brain injury, what choices would you want to make? If you were unable to breathe, would you want a tube, attached to a ventilator, placed into your lungs? The answer may be yes -- but not indefinitely. If that's the case, then for how long? Would you consider a tracheostomy, if you were on a ventilator for more than two weeks? Again, the answer may be yes. How about a feeding tube that enters your stomach through your skin? For how long would you want such a measure?

These are not easy topics to consider, or to discuss with the ones you love. But they are important. Ideally, doctors could help with the discussion about end of life, but because the nature of doctors is to treat and heal, many have difficulty discussing end-of-life decisions with their patients. Studies have shown that even with patients who face a life-limiting disease, physicians discuss advance directives only 40 to 45 percent of the time.

One study posed a hypothetical situation in which a man with stage 4 gastric cancer, metastasized to his lung, comes to the emergency room with his wife for severe shortness of breath. The husband and wife in this scenario did not have an advance directive, but their preference was for the husband to remain comfortable and out of the intensive care unit. Only 48 percent of the 27 physicians who treated this hypothetical patient were able to coax out the appropriate information in order to treat him in accordance with his goals and preferences.

Now, I know you don't have gastric cancer, but death is an inevitability. Providing your loved ones, the medical system and yourself direction about your course of care gives you some control over that inevitability.

Exercise and Diet Help Reduce Risk for Vascular Dementia

Dear Doctor: My dad has just been diagnosed with vascular dementia. What is it? Can it be prevented?

Dear Reader: Dementia is a general term used to categorize symptoms that relate to the decline or loss of cognitive function. These include confusion, memory loss, impaired language skills, changes in personality or behavior, and the inability to think clearly or perform everyday tasks. The most common cause of dementia is Alzheimer's disease, which accounts for between 60 and 80 percent of all dementia cases. The mental impairment of Alzheimer's disease results from a series of complex changes that take place within the structure of the brain itself.

Vascular dementia, which is also called vascular cognitive impairment, causes the majority of non-Alzheimer's cases of dementia. It occurs when the blood vessels in the body, known as the vascular system, become blocked, diseased or damaged and are unable to provide the brain with normal blood flow. This deprives the brain of adequate oxygen and nutrition, which causes brain cells to die. The resulting injury, which prevents different parts of the brain from communicating with one another, causes symptoms of dementia.

Hardening and narrowing of the arteries, a major stroke or a series of small strokes can cause vascular dementia. In the case of major stroke, symptoms of vascular dementia can appear suddenly. But quite often, the disease builds slowly. As blood flow to the brain decreases, mental impairment gradually becomes more pronounced.

At this time, vascular dementia cannot be reversed, but there are steps you can take to reduce your risk of developing it. Although the disease is rare before age 65, the cardiovascular problems that lead to it can begin to develop well before then.

One of the major risk factors for vascular dementia is high blood pressure, which also plays a role in heart attack and stroke. That's why it's important to know your numbers, and to monitor blood pressure on a regular basis.

To reduce blood pressure, maintain a healthy weight. It's wise to also keep track of your waistline measurements. Men who measure more than 40 inches at the waist and women whose waistlines measure more than 35 inches are at increased risk of developing high blood pressure.

Get moving. Regular exercise has been shown to reduce the risk of vascular dementia by 40 percent. Just 30 minutes of exercise at moderate intensity -- you'll be able to speak but not sing -- three times per week helps protect both your heart and your brain.

If you've been following this column for even a few weeks you know what's coming next -- don't smoke. If you do smoke, please stop. Yes, we know that's hard. We also know that your family doctor would love to help you.

Eat a healthy diet: lean meats, fresh fish, legumes, whole grains, seeds, nuts, and plenty of fruits and vegetables. Skip the sugar if you can. Limit simple carbs like pasta, rice, bread and processed cereals.

Limit how much alcohol you drink. Even in moderation, alcohol has been linked to dementia risk, particularly as we get older.
