osteoarthritides

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.

Osteoarthritis affects people in different ways, and not everyone has pain. The most common symptoms are:

• Pain when you move, which often gets better with rest
• Stiffness, especially for the first 30 minutes after you get up from resting
• Swollen joints, especially after using the joint a lot
• Less movement in the joint than normal
• A joint that feels loose or unstable

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.

Things that make you more likely to develop osteoarthritis include:

• Aging. Osteoarthritis can happen at any age, but the chance of getting it increases in middle-aged adults and older. After age 50, it is more common in women than in men.
• Being overweight. Extra weight puts more stress on your joints.
• Having a past injury or surgery on a joint. This is often the cause of osteoarthritis in younger adults.
• Doing a lot of activities that overuse the joint. This includes sports with a lot of jumping, twisting, running, or throwing.
• Having a joint that doesn't line up correctly.
• A family history of osteoarthritis. Some people inherit genetic changes that increase their chance of developing osteoarthritis.

There is no specific test for osteoarthritis. To find out if you have osteoarthritis, your provider:

• Will ask about your symptoms and medical history
• Will do a physical exam
• May use x-rays or other imaging tests to look at your joints
• May order lab tests to make sure that a different problem isn't causing your symptoms

The goal of treating osteoarthritis is to ease your pain, help you move better, and stop it from getting worse.

Treatment usually begins with:

• Exercises to improve strength, flexibility and balance
• Weight loss, if needed, to improve pain, especially in your hips or knees
• Braces or shoe inserts (orthotics) that a health care provider fits for you

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.

If you feel pain and stiffness in your body or have trouble moving around, you might have arthritis. Most kinds of arthritis cause pain and swelling in your joints. Joints are places where two bones meet, such as your elbow or knee. Over time, a swollen joint can become severely damaged. Some kinds of arthritis can also cause problems in your organs, such as your eyes or skin.

Types of arthritis include:

• Osteoarthritis is the most common type of arthritis. It's often related to aging or to an injury.
• Autoimmune arthritis happens when your body's immune system attacks healthy cells in your body by mistake. Rheumatoid arthritis is the most common form of this kind of arthritis.
• Juvenile arthritis is a type of arthritis that happens in children.
• Infectious arthritis is an infection that has spread from another part of the body to the joint.
• Psoriatic arthritis affects people with psoriasis.
• Gout is a painful type of arthritis that happens when too much uric acid builds up in the body. It often starts in the big toe.

Cartilage is the tough but flexible tissue that covers the ends of your bones at a joint. It also gives shape and support to other parts of your body, such as your ears, nose and windpipe. Healthy cartilage helps you move by allowing your bones to glide over each other. It also protects bones by preventing them from rubbing against each other.

Injured, inflamed, or damaged cartilage can cause symptoms such as pain and limited movement. It can also lead to joint damage and deformity. Causes of cartilage problems include :

• Tears and injuries, such as sports injuries
• Genetic factors
• Other disorders, such as some types of arthritis

Osteoarthritis results from breakdown of cartilage.

Hip replacement is surgery for people with severe hip damage. The most common cause of damage is osteoarthritis. Osteoarthritis causes pain, swelling, and reduced motion in your joints. It can interfere with your daily activities. If other treatments such as physical therapy, pain medicines, and exercise haven't helped, hip replacement surgery might be an option for you.

During a hip replacement operation, the surgeon removes damaged cartilage and bone from your hip joint and replaces them with new, man-made parts.

A hip replacement can:

• Relieve pain
• Help your hip joint work better
• Improve walking and other movements

The most common problem after surgery is hip dislocation. Because a man-made hip is smaller than the original joint, the ball can come out of its socket. The surgery can also cause blood clots and infections. With a hip replacement, you might need to avoid certain activities, such as jogging and high-impact sports.

Your joints are places where two or more bones come together. Your shoulders, elbows, hips, knees, and knuckles are all joints. Your spine has joints, too.

But joints are more than bones. They include the soft tissues around them, such as cartilage, tendons and ligaments. Cartilage is the hard slippery flexible tissue that covers the ends of your bones at a joint. Tendons are tough, flexible bands that connect your muscles to your bones so you can move your joints. Ligaments connect the bones of the joint to each other to keep them stable when you move.

Joint disorders are diseases or injuries that affect your joints. Injuries can happen because of overuse of a joint. Or you could have a sudden injury, such as an accident or a sports injury.

Many diseases can affect the joints. They often cause joint pain and make your joints stiff, red, or swollen. Most of them are chronic. That means they last a long time. Some may never go away completely. Some of the diseases that affect the joints include:

• Arthritis. Arthritis may cause joint pain and swelling. There are many types of this disease. Osteoarthritis is the most common type. Over time, arthritis can cause severe joint damage. It can affect people of all ages. A joint injury when you're young may cause osteoarthritis later in life.
• Lupus. This autoimmune disease affects many parts of the body and can cause joint and muscle pain. Some types of lupus often cause arthritis.
• Sjögren's Syndrome. This autoimmune disease affects glands that make moisture in many parts of the body. The main symptoms are dry eyes and mouth, but it often causes joint pain, too.

Treatments are different depending on the disease. But most treatments include medicines and therapies to relieve pain and other symptoms.

Joint disorders from sudden injuries include:

• Sprains and strains. Sprains are stretched or torn ligaments. Acute strains are stretched or torn muscles or tendons that happen from a sudden injury or movement, such as lifting a heavy object.
• Dislocated joints. A joint is dislocated when the bones are pushed or pulled out of position. A joint dislocation is a medical emergency.

Treatment depends on the type of injury. You can treat many sports injuries at home. But you should call your health care provider if you:

• Have a lot of joint pain, swelling or numbness
• Can't put weight on the joint
• Have pain from an old injury with more swelling, an unstable joint, or a joint that isn't normal in another way

Overuse injuries usually damage the soft tissues of the joint. They can happen when you work a joint too hard by doing the same movements over and over. For example, you could get an overuse injury from playing a musical instrument, playing sports, or doing certain jobs, such as carpentry or painting.

Joint overuse injuries include:

• Bursitis. The bursa is a small fluid-filled sac. It works as a pad between the bones of a joint and the moving parts around it, such as muscles, tendons and skin. With bursitis, the bursa becomes irritated and swollen with extra fluid. Overuse is the most common cause, but injuries, infections and other conditions, such as arthritis, can cause bursitis.
• Tendinitis. This condition happens when you overuse a tendon. It swells and makes the joint painful to move.
• Chronic strain. A strain becomes chronic when your muscles or tendons stretch or tear slowly over time from repeating the same movements.

The treatments for bursitis, tendinitis, and chronic strain are often the same. They usually include rest, keeping the injured joint higher than your heart, and taking medicine to reduce swelling. Your provider may recommend gentle exercise and other treatment. In some cases, your provider may suggest an injection (a shot) of medicine into the joint. If these do not help, you may need surgery.

Getting enough physical activity is one of the most important things you can do to prevent or slow joint disorders. Activity strengthens the muscles around your joints and helps them work better.

When you play sports, wear the right equipment to protect your joints, such as knee pads. If you already have joint problems, ask your provider what type of activities are best for you.

Your ankle bone and the ends of your two lower leg bones make up the ankle joint. Your ligaments, which connect bones to one another, stabilize and support it. Your muscles and tendons move it.

The most common ankle problems are sprains and fractures (broken bones). A sprain is an injury to the ligaments. It may take a few weeks to many months to heal completely. A fracture is a break in a bone. You can also injure other parts of the ankle such as tendons, which join muscles to bone, and cartilage, which cushions your joints. Ankle sprains and fractures are common sports injuries.

Of the 206 bones in your body, three of them are in your arm: the humerus, radius, and ulna. Your arms are also made up of muscles, joints, tendons, and other connective tissue. Injuries to any of these parts of the arm can occur during sports, a fall, or an accident.

Types of arm injuries include :

• Tendinitis and bursitis
• Sprains
• Dislocations
• Fractures (broken bones)
• Nerve problems
• Osteoarthritis

You may also have problems or injure specific parts of your arm, such as your hand, wrist, elbow, or shoulder.

Fibromyalgia is chronic (long-lasting) condition that causes pain all over the body, fatigue, and other symptoms. There is no cure, but treatments can help with the symptoms.

The exact cause of fibromyalgia is unknown. Studies of the brains of people with fibromyalgia found that they seem to process pain differently than people who don't have it. They may feel pain when others do not, and they may also have a more severe reaction to pain.

Fibromyalgia can run in families, so genetics may also play a role. Other factors may also be involved, such as having certain diseases that cause pain.

Anyone can get fibromyalgia, but it is more common in:

• Women; they are twice as likely to have fibromyalgia
• Middle-aged people; your chance of having it increases as you get older
• People with certain diseases, such as lupus, rheumatoid arthritis, osteoarthritis or ankylosing spondylitis
• People who have a family member with fibromyalgia

The main symptoms of fibromyalgia are:

• Chronic (long-lasting) pain and stiffness all over the body. People often describe it as aching, burning, or throbbing.
• Fatigue and tiredness.
• Trouble sleeping.

Other symptoms may include:

• Problems with thinking, memory, and concentration (sometimes called "fibro fog")
• Muscle and joint stiffness
• Numbness or tingling in the arms and legs
• Sensitivity to light, noise, odors, and temperature

People who have fibromyalgia are also more likely to have certain diseases, including:

• Anxiety
• Depression
• Headaches, including migraines
• Irritable bowel syndrome
• Pain in the face or jaw, including disorders of the jaw know as temporomandibular joint syndrome (TMJ)

Fibromyalgia can be hard to diagnose. It sometimes takes visits to several different health care providers to get a diagnosis. One problem is that there isn't a specific test for it. And the main symptoms, pain and fatigue, are common in many other conditions. Providers have to rule out other causes of the symptoms before making a diagnosis of fibromyalgia. This is called making a differential diagnosis.

To find out if you have fibromyalgia, your provider:

• Will take your medical history, including asking detailed questions about your symptoms
• Will do a physical exam
• May order x-rays and blood tests to rule out other conditions

Not all providers are familiar with fibromyalgia and its treatment. You should see a provider or team of providers who specialize in the treatment of fibromyalgia.

There is no cure for fibromyalgia, so treatment focuses on relieving the symptoms. Providers usually use a combination of treatments, including medicines, lifestyle changes, talk therapy, and complementary therapies:

• Medicines
• Certain antidepressants and anti-seizure medicines, which may help with pain or sleep problems.
• Pain relievers.
• Lifestyle changes
• Getting enough sleep.
• Getting regular physical activity. If you have not already been active, start slowly and gradually increase how much activity you get. You may want to see a physical therapist, who can help you create a plan that is right for you.
• Learning how to manage stress.
• Learning to pace yourself. If you do too much, it can make your symptoms worse. So you need to learn to balance being active with your need for rest.
• Talk therapy, such as cognitive behavioral therapy (CBT), can help you learn strategies to deal with pain, stress, and negative thoughts. If you also have depression along with your fibromyalgia, talk therapy can help with that too.
• Complementary therapies have helped some people with the symptoms of fibromyalgia. But researchers need to do more studies to show which ones are effective. You could consider trying them, but you should check with your provider first. These therapies include:
• Mindfulness meditation.
• Biofeedback, which uses electronic devices to measure body functions such as breathing and heart rate. This teaches you to be more aware of your body functions so you can learn to control them.
• Movement therapies such as yoga and tai chi.
• Massage therapy.
• Acupuncture.

You use your fingers and thumbs to do everything from grasping objects to playing musical instruments to typing. When there is something wrong with them, it can make life difficult. Common problems include:

• Injuries that result in fractures (broken bones), ruptured ligaments and dislocations
• Osteoarthritis - wear-and-tear arthritis. It can also cause deformity.
• Tendinitis - irritation of the tendons
• Dupuytren's contracture - a hereditary thickening of the tough tissue that lies just below the skin of your palm. It causes the fingers to stiffen and bend.
• Trigger finger - an irritation of the sheath that surrounds the flexor tendons. It can cause the tendon to catch and release like a trigger.

Each of your feet has 26 bones, 33 joints, and more than 100 tendons, muscles, and ligaments. No wonder a lot of things can go wrong. Here are a few common problems:

• Bunions - hard, painful bumps on the big toe joint
• Corns and calluses - thickened skin from friction or pressure
• Plantar warts - warts on the soles of your feet
• Fallen arches - also called flat feet

Ill-fitting shoes often cause these problems. Aging and being overweight also increase your chances of having foot problems.
