Hip Replacement Surgery Should Be Last Resort

Dear Doctor: How do I know if I need a hip replacement? My right hip gets so stiff after I’ve been sitting at work for a few hours that I can hardly walk, and then it aches for the rest of the day and night.

Dear Reader: The hip is one of the largest weight-bearing joints of the body. Its unique structure lets humans stand and walk upright and gives our legs and torso an impressively wide range of motion. It is a ball-and-socket joint, which means that the rounded head of a bone fits neatly into a cuplike hollow. In the case of the hip joint, the ball-shaped head of the femur, which is the upper leg bone, sits inside a socket within the hip, known as the acetabulum. The surfaces of the femur and the hip socket are lined with cartilage, a smooth and springy connective tissue that cushions the joint and helps reduce friction. A membrane known as the synovium produces a thick liquid that lubricates and nourishes the interior of the joint. Fluid-filled sacs known as bursae act as cushions and protect the muscles and tendons as they move over bony areas within the joint. Muscles, ligaments and tendons anchor the hip joint and provide power, stability and flexibility.

The most common reason for a hip replacement is damage to the parts of the joint that reduce pressure and eliminate friction. This often occurs due to osteoarthritis, a degenerative condition in which the tissues of the joint begin to deteriorate, and rheumatoid arthritis, a chronic inflammatory disorder. Injuries, fractures, wear-and-tear due to overuse or being overweight, and cancer, while less common, also can lead to the need for a hip replacement.

One of the main symptoms that the joint may need to be replaced is significant and persistent pain. This occurs while walking, sitting, standing or bending over, and often is severe enough to wake you from sleep. It interferes with the ability to carry out daily activities and impairs quality of life. Imaging tests that reveal arthritis, or damage to the bone or tissues of the joint from other causes, also may signal the need for joint replacement.

A hip replacement is major surgery. It entails removing the damaged or diseased tissues and replacing them with an artificial joint. Post-surgical physical therapy is a big part of a successful outcome, and full recovery can take from six months to a year. It is important to note that the new joint lasts about 15 years, after which it will need to be replaced again. Before diving into the deep end, your health care provider is likely to ask you to explore noninvasive interventions. These include rest, physical therapy, weight loss, using a cane and a range of anti-inflammatory or pain medications. If these fail to provide adequate relief, or if the medications are not tolerated, then a new joint may be the best option.

If you do opt for a hip replacement, find a reputable and experienced surgeon. You want someone who is board certified in orthopedic surgery, specializes in hip replacement, has experience with your specific condition and accepts your insurance.

Not Everyone With Lung Cancer Will Get a Cough

Ask the Doctors by by Eve Glazier, M.D. and Elizabeth Ko, M.D

Dear Doctor: Our sister saw her doctor because her chest felt “heavy,” and he found fluid in her lung. Further tests showed lung cancer, which had already spread. She never coughed, and she quit smoking years ago. What are some of the symptoms of lung cancer?

Dear Reader: Although a cough can be an indication of lung cancer, it is not the only sign of the disease, and it doesn’t appear in every case. Lung cancer can take years to develop; in its earlier stages, people may have no symptoms at all. When the disease does begin to make itself known, some of the symptoms can be unusual, and, thus, not immediately associated with lung cancer.

Let’s start with a cough. It’s one of the more common symptoms of lung cancer, and it appears in up to half of all patients. This can be a new and persistent cough that isn’t associated with a cold or the flu, or it can be a chronic cough that gradually becomes worse. These coughs may be painful, and they may produce red or rust-colored phlegm or sputum, which indicates the presence of blood. Any time that you cough up blood -- whether it is bright red, which indicates new blood, or a darker hue, which signals old blood -- it’s important to see a doctor.

The presence of fluid, as in the case of your sister, is known as pleural effusion. It’s not actually inside the lungs, but in an area between the lungs and the chest wall, which is known as the pleural space. When it is associated with cancer, the condition is known as malignant pleural effusion, and it is a sign that the disease has spread. The buildup of fluid in the pleural space causes the sensation of heaviness that your sister reported, sometimes also described as a feeling of tightness. Often, it is accompanied by shortness of breath, a dry cough and exhaustion. Pleural effusion can be life-threatening, and the fluid must be drained.

Additional symptoms of lung cancer include chest pain, hoarseness, frequent bouts of bronchitis or pneumonia and persistent chest pain. Symptoms of the disease that are not lung-related include persistent fatigue or malaise, loss of appetite, unexplained weight loss, swollen or enlarged lymph nodes and shoulder or upper-back pain. Some patients develop an enlargement of the fingertips, known as clubbing. It’s important to note that each of these, including cough, can be caused by other conditions.

For adults who are at a higher risk of developing lung cancer, the recent development of an early stage screening test has been an important advance. Known as low-dose computed tomography, or a low-dose CT scan, it’s recommended for adults between the ages of 55 and 80 who are heavy smokers, or who were heavy smokers and quit less than 15 years ago. The scan, which uses a small amount of radiation, makes a detailed image of the lungs. Risks of the test include false positives, which can lead to unnecessary surgical procedures, and exposure to radiation, which itself can cause cancer. Anyone interested in the test should check with their doctor to see if they meet the screening criteria.

Older Adults Still Need Regular Exercise

Dear Doctor: Our dad is 78 years old, and he has started spending a lot more time indoors and on his recliner. He’s in good health, but he says he’s getting too old for exercise to matter. What can we say to persuade him to become active again?

Dear Reader: Exercise is an important part of ongoing health and fitness, and, despite your dad’s feelings to the contrary, we never age out of our need for it.

In fact, studies show that becoming or remaining active as an older adult offers a wide array of benefits. On the physical side, regular exercise can improve cardiovascular health; help to lower blood pressure; lessen the risk of chronic diseases such as Type 2 diabetes, colon cancer and heart disease; help with balance, strength and flexibility; maintain healthy weight; improve strength and stamina; maintain joint health; help with swelling and pain due to arthritis; and lower the risk of falls. Regular exercise has mental health benefits as well. Older adults who incorporate even moderate amounts of exercise into their daily lives report enhancement to mood and outlook, improved cognitive function and a reduction in symptoms of anxiety and depression. Remaining physically active also has been shown to help older adults maintain their ability to live independently.

For a well-rounded exercise program, think in terms of a mix of activities to improve endurance, increase strength and maintain flexibility. And be creative. Walking, jogging, swimming and biking all fit the bill for moderate aerobic activities for endurance, but so do dancing, raking the lawn or playing badminton. We lose muscle mass as we age, so strength and resistance exercises, such as weightlifting or Pilates, are important. Activities like stretching, tai chi and yoga help keep joints loose and muscles limber. Current guidelines recommend that people 65 and older should do 2.5 hours of moderate aerobic exercise each week, which averages out to a manageable 20-ish minutes per day.

Although sharing this information with your dad is a good start, leading by example is even better. It’s not just older adults who fall short of the recommended levels of exercise and physical activity; up to half of all adults miss the mark. If you and your siblings live nearby, it could be helpful to your dad -- and to yourselves -- to choose an activity to do together once or twice a week and get up and moving.

A final thought: If your dad has supplementary Medicare coverage, check to see if it includes SilverSneakers. It’s a health-and-fitness program designed for older adults that will give him access to a range of fitness options, including gyms, community centers and other fitness locations. And remember, your dad should check in with his doctor or other health care provider before making any significant changes to his exercise regimen or activity. They will be able to evaluate his condition and fitness level and point him in the direction of appropriate activities. Not only will it help your dad to stay safe, he’ll have another partner and cheerleader in his corner.
