Upset Over Your Figure? Some Bodies Really Are Painful
Orthopaedic surgeons explain how some common body features really do cause pain.
April 10, 2008— -- People may not always talk about it, but many in America feel hurt over their body type and physical features.
There's the obvious emotional angst of those whose figures don't compete with those of swimsuit models or Hollywood starlets. But then, there's the actual physical pain.
At least 15 percent of the population has complained of musculoskeletal pain in the last year: more than people with allergies and headaches combined, according to "The Burden of Musculoskeletal Disease in the United States," a publication from the United States Bone and Joint Decade.
Some of this pain comes from injury, but some also occurs as a result of a person's specific body type. If you ask orthopaedists, it turns out that, what we might think makes us beautiful, doesn't help us feel pain-free.
Though children usually outgrow being pigeon-toed, called in-toeing by doctors, the stance can persist or get worse in adulthood, often caused by a rotational twist in the tibia (shin bone) or a twist in the femur (thigh bone) as it connects to the hip.
If the problem worsens, so might the person's pain. The weight of a person who walks with a pigeon-toed frame puts stress on parts of the body not designed to take it.
"The forces on your ankles, on the tendons around your ankles, can cause pain," said Dr. Lonnie Paulos, director of the Texas Sports Medicine Alliance in Houston, Texas. Paulos noted that flat feet, another painful problem, often accompanies a pigeon-toed stance.
If a person's pigeon-toed gait worsens, the kneecap can wear out faster, as well as the joints in the ankles. That wear and tear can cause an early or more severe onset of osteoarthritis.
A buxom woman can suffer welts on her shoulders from her bra straps, and running or other aerobics can hurt without the right support. Even sitting still can cause pain for big-breasted women.
"If they are real large, they pull your shoulders forward," Paulos said. "The shoulders, neck and back will hurt."
Female patients accounted for about 60 percent of the health care visits for neck pain in 2004, according to "The Burden of Musculoskeletal Disease in the United States."
Unlike many other forms of pain from body types, there's not much a full-chested woman can do.
"That's the reason why, many years ago, they developed the support bra," Paulos said.
Beyond bras, the American Society of Plastic Surgeons reports that 106,000 women had breast reduction surgery in 2007. In the same year, more than three times that number of women decided to get breast augmentation.
People who stay thin unnaturally may lose critical elements for conditioning the joints, Paulos said. They may have bone pain from loss of calcium, vitamin C and vitamin D.
Even the so-called enviable people who stay thin naturally, but never exercise and eat whatever they want, might be at risk. These people, especially women, are more likely to get painful fractures from osteoporosis later in life.
"Having a thin frame is a recognized risk factor," said Dr. Laurence Laudicina, a spokesman for the American Academy of Orthopaedic Surgeons.
It turns out that so-called big-boned women truly do have more bone than thin-framed women. Once menopause hits, these big-boned women have more bone to lose before one breaks.
And for thin women who like to party, take note: combine a thin frame with a sedentary lifestyle, smoking and heavy drinking and a woman increases her risk for osteoporosis even more, Laudicina said.
"The muscles act like springs, so if you're jumping and running around and have very weak springs, all of the forces will go to your bones," Paulos said.
Without the cushion of strong muscles, some of the most essential joints in the hips, the back and the knees will suffer, sometimes permanently.
"If you think of someone who is heavy or overweight, while their bones become denser, there's more pressure on the cartilage," Laudicina said. Over time, the cartilage wears away, slowly causing arthritis and pain.
And the more you gain, the more pain.
"If a person is 10 pounds overweight and goes up the stairs, they will see 80 pounds extra weight on the knee," Paulos said. "So you can imagine the forces a knee will see if they're at 250 pounds, overweight and weak."
With this proper alignment, a person's back will have three natural curves. But with a big belly out front, the muscles in the back take on extra stress to hold the person upright. The result is bad lower back pain.
"It pulls your back in the wrong direction," Paulos said. "If your lower back is weak, then you'll have more arthritis in your spine."
Besides the obvious goal to lose the belly weight, Laudicina advised all people to pay attention to their posture and alignment.
"That has a definite impact over time," Laudicina said. Sitting up straight — Forest Gump-style with both feet planted on the floor — and simply standing up straight will save many people from unwanted aches and pains.
The change in body mass distribution also puts women at risk for hip, ankle and calf pain.
Then, enter the hormones. In order to push the baby out, it helps if the joints in the pelvis can flex and move a bit, Paulos said. To accommodate this need, the body releases joint-relaxing hormones.
"But they don't discriminate," Paulos said. "When you're pregnant, all your ligaments in your joints relax."
As a result, pregnant women's kneecaps can start to wobble and hurt. So may their spines. The best thing to do, Paulos said, is to be fit before pregnancy and stay fit during pregnancy.
"As far as the orthopaedic aspects of being heavy, carrying extra strength to carry the extra weight will reduce pain," Paulos said.
"As the bones grow, they do cause a little inflammation and pain," Paulos said. "But if you are heavy as a kid, it separates the growth center from the rest of the bone and it can cause pain and inflammation.
"Bad alignment and heavy weight can affect the growth centers of growing children," he said, adding that disease and rickets can have the same effect.
The problem of overweight children is growing, along with adult obesity in America. Sixteen percent of children and teenagers are overweight — triple what the proportion was in 1980.
In January, the surgeon general put out a call to fight childhood obesity and overweight problems. In addition to bone pain, overweight children face a higher life risk for type 2 diabetes, heart disease and a 70 percent chance of becoming overweight or obese as adults.
Infants often look bow-legged before the age of two, but the shape naturally corrects itself as the child grows and begins to walk. However, several factors, like genetics, Blunts' disease (a bone growth disorder) or rickets (caused by vitamin deficiencies) may contribute to the permanent bone curvatures that give the distinctive "bow" shape.
Though not particularly painful if temporary in children, over time, bow-legged adults may face knee pain from the change in their legs' alignment.
"All your weight goes through the center of gravity, down through the center of your pelvis," Paulos said.
But when a person is bow-legged, the majority of the weight can't bear down on the center of the knee, its strongest part. Instead, the force is greater on the inside of the knee.
Even without osteoporosis, severe kyphosis (the medical term for being hunched over) can cause neck and back pain. Kyphosis can even cause breathing problems.
But don't feel doomed to shrink. Stand up straight, literally.
Over time, strengthening the muscles in your back can keep you from hunching and may also improve your alignment, preventing further pain. "The forces exchange from one joint to the other," Laudicina said. "There can be weak links in those chains."
Eating enough vitamin D and calcium can keep bones strong, preventing the tiny fractures that contribute to height loss. However, according to the Harvard Health Letter, the best way to keep your bones strong is to stay active.
When a person with normal feet walks, his or her heel hits first and the foot rolls toward the toes, flattening the arch slightly. Then, the arch springs back as the person pushes off the ball of the foot, according to the American Orthopaedic Foot & Ankle Society.
Walking with flat feet will cause over-pronation, meaning the foot rolls too much to the inside, frequently causing pain to the inside of the knee.
"Tendons around your ankles also tend to wear out when you're really flat-footed," Laudicina said.
Flat feet are usually inherited and are caused by lax tendons and ligaments in the foot.
An easy way to determine flat feet is the wet test. Step in an inch of standing water or even paint and then step on cardboard.
A person with a high arch will have little to no mark between the heel and the ball of the foot. A person with a normal foot will have some flesh between the heel and the ball of the foot, while a person with a flat foot will have full pad marks from the heel to the toes.
Often, a trip to an orthopaedist for shoe inserts can greatly help pain from flat feet.
