Your backbone, or spine, is made up of 26 bones called vertebrae. In between them are soft disks filled with a jelly-like substance. These disks cushion the vertebrae and keep them in place. As you age, the disks break down or degenerate. As they do, they lose their cushioning ability. This can lead to pain if the back is stressed.
A herniated disk is a disk that ruptures. This allows the jelly-like center of the disk to leak, irritating the nearby nerves. This can cause sciatica or back pain.
Your doctor will diagnose a herniated disk with a physical exam and, sometimes, imaging tests. With treatment, most people recover. Treatments include rest, pain and anti-inflammatory medicines, physical therapy, and sometimes surgery.

Your backbone, or spine, is made up of 26 bone discs called vertebrae. The vertebrae protect your spinal cord and allow you to stand and bend. A number of problems can change the structure of the spine or damage the vertebrae and surrounding tissue. They include:
Spinal diseases often cause pain when bone changes put pressure on the spinal cord or nerves. They can also limit movement. Treatments differ by disease, but sometimes they include back braces and surgery.
Your back is made of bones, muscles, and other tissues extending from your neck to your pelvis. Back injuries can result from sports injuries, work around the house or in the garden, or a sudden jolt such as a car accident. The lower back is the most common site of back injuries and back pain. Common back injuries include :
These injuries can cause pain and limit your movement. Treatments vary but might include medicines, icing, bed rest, physical therapy, or surgery. You might be able to prevent some back injuries by maintaining a healthy weight, lifting objects with your legs, and using lower-back support when you sit.
If you've ever groaned, "Oh, my aching back!", you are not alone. Back pain is one of the most common medical problems, affecting 8 out of 10 people at some point during their lives. Back pain can range from a dull, constant ache to a sudden, sharp pain. Acute back pain comes on suddenly and usually lasts from a few days to a few weeks. Back pain is called chronic if it lasts for more than three months.
Most back pain goes away on its own, though it may take awhile. Taking over-the-counter pain relievers and resting can help. However, staying in bed for more than 1 or 2 days can make it worse.
If your back pain is severe or doesn't improve after three days, you should call your health care provider. You should also get medical attention if you have back pain following an injury.
Treatment for back pain depends on what kind of pain you have, and what is causing it. It may include hot or cold packs, exercise, medicines, injections, complementary treatments, and sometimes surgery.

Computed tomography (CT) is a type of imaging. It uses special x-ray equipment to make cross-sectional pictures of your body.
Doctors use CT scans to look for:
During a CT scan, you lie still on a table. The table slowly passes through the center of a large X-ray machine. The test is painless. During some tests you receive a contrast dye, which makes parts of your body show up better in the image.

Osteoarthritis, sometimes called OA, is a type of arthritis that only affects the joints, usually in the hands, knees, hips, neck, and lower back. It's the most common type of arthritis.
In a healthy joint, the ends of the bones are covered with a smooth, slippery tissue called cartilage. The cartilage pads the bones and helps them glide easily when you move the joint. With osteoarthritis, the cartilage breaks down and becomes rough. Sometimes, all the cartilage wears away and the bones rub together. Bumps of extra bone called bone spurs may grow in the joint area.
There is no cure for osteoarthritis. It usually gets worse slowly. But there's a lot you can do to manage the symptoms.
What are the symptoms of osteoarthritis?Osteoarthritis affects people in different ways, and not everyone has pain. The most common symptoms are:
Researchers aren't sure what causes osteoarthritis. They think that it could be caused by a combination of factors in the body and the environment. Your chance of developing osteoarthritis increases with age. They also know that some people are more likely to develop it than others.
Who is more likely to develop osteoarthritis?Things that make you more likely to develop osteoarthritis include:
There is no specific test for osteoarthritis. To find out if you have osteoarthritis, your provider:
The goal of treating osteoarthritis is to ease your pain, help you move better, and stop it from getting worse.
Treatment usually begins with:
You can buy some pain relievers and arthritis creams without a prescription. They can be helpful, but it's best to talk to your provider about using them. If they don't help enough, your provider may prescribe injections (shots) into the joint or prescription pain relievers.
Complementary therapies may help some people. Massage can increase blood flow and bring warmth to the area. Some research shows that acupuncture may help relieve osteoarthritis pain. Simple things like heat and ice can help, too.
If none of these treatments help enough, surgery may be an option. You and your provider can decide if it's right for you.

Osteoporosis is a disease that thins and weakens the bones. Your bones become fragile and fracture (break) easily, especially the bones in the hip, spine, and wrist. In the United States, millions of people either already have osteoporosis or are at high risk due to low bone mass.
Anyone can develop osteoporosis, but it is more common in older women. Risk factors include:
Osteoporosis is a silent disease. You might not know you have it until you break a bone. A bone mineral density test is the best way to check your bone health.
To keep bones strong, eat a diet rich in calcium and vitamin D, exercise, and do not smoke. If needed, medicines can also help. It is also important to try to avoid falling down. Falls are the number one cause of fractures in older adults.

Scoliosis causes a sideways curve of your backbone, or spine. These curves are often S- or C-shaped. Scoliosis is most common in late childhood and the early teens, when children grow fast. Girls are more likely to have it than boys. It can run in families. Symptoms include leaning to one side and having uneven shoulders and hips. Sometimes it is easy to notice, but not always.
Children may get screening for scoliosis at school or during a checkup. If it looks like there is a problem, your doctor will use your medical and family history, a physical exam, and imaging tests to make a diagnosis. Treatment depends on your age, how much more you're likely to grow, how much curving there is, and whether the curve is temporary or permanent. People with mild scoliosis might only need checkups to see if the curve is getting worse. Others might need to wear a brace or have surgery.

X-rays are a type of radiation called electromagnetic waves. X-ray imaging creates pictures of the inside of your body. The images show the parts of your body in different shades of black and white. This is because different tissues absorb different amounts of radiation. Calcium in bones absorbs x-rays the most, so bones look white. Fat and other soft tissues absorb less and look gray. Air absorbs the least, so lungs look black.
The most familiar use of x-rays is checking for fractures (broken bones), but x-rays are also used in other ways. For example, chest x-rays can spot pneumonia. Mammograms use x-rays to look for breast cancer.
When you have an x-ray, you may wear a lead apron to protect certain parts of your body. The amount of radiation you get from an x-ray is small. For example, a chest x-ray gives out a radiation dose similar to the amount of radiation you're naturally exposed to from the environment over 10 days.
