Arm Injuries and Disorders

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.

Vascular Diseases

What are vascular diseases?

Your vascular system is your body's network of blood vessels. It includes your:

• Arteries, which carry oxygen-rich blood from your heart to your tissues and organs
• Veins, which carry the blood and waste products back to your heart
• Capillaries, which are tiny blood vessels that connect your small arteries to your small veins. The walls of the capillaries are thin and leaky, to allow for an exchange of materials between your tissues and blood.

Vascular diseases are conditions which affect your vascular system. They are common and can be serious. Some types include:

• Aneurysm - a bulge or "ballooning" in the wall of an artery
• Atherosclerosis - a disease in which plaque builds up inside your arteries. Plaque is made up of fat, cholesterol, calcium, and other substances found in the blood.
• Blood clots, including deep vein thrombosis and pulmonary embolism
• Coronary artery disease and carotid artery disease, diseases that involve the narrowing or blockage of an artery. The cause is usually a buildup of plaque.
• Raynaud's disease - a disorder that causes the blood vessels to narrow when you are cold or feeling stressed
• Stroke - a serious condition that happens when blood flow to your brain stops.
• Varicose veins - swollen, twisted veins that you can see just under the skin
• Vasculitis - inflammation of the blood vessels

What causes vascular diseases?

The causes of vascular diseases depend on the specific disease. These causes include:

• Genetics
• Heart diseases such as high cholesterol and high blood pressure
• Infection
• Injury
• Medicines, including hormones

Sometimes the cause is unknown.

Who is at risk for vascular diseases?

The risk factors for vascular diseases can vary, depending on the specific disease. But some of the more common risk factors include:

• Age - your risk of some diseases goes up as you get older
• Conditions that can affect the heart and blood vessels, such as diabetes or high cholesterol
• Family history of vascular or heart diseases
• Infection or injury that damages your veins
• Lack of exercise
• Obesity
• Pregnancy
• Sitting or standing still for long periods of time
• Smoking

What are the symptoms of vascular diseases?

The symptoms for each disease are different.

How are vascular diseases diagnosed?

To make a diagnosis, your health care provider will do a physical exam and ask about your symptoms and medical history. You may have imaging tests and/or blood tests.

How are vascular diseases treated?

Which treatment you get depends on which vascular disease you have and how severe it is. Types of treatments for vascular diseases include:

• Lifestyle changes, such as eating a heart-healthy diet and getting more exercise
• Medicines, such as blood pressure medicines, blood thinners, cholesterol medicines, and clot-dissolving drugs. In some cases, providers use a catheter to send medicine directly to a blood vessel.
• Non-surgical procedures, such as angioplasty, stenting, and vein ablation
• Surgery

Can vascular diseases be prevented?

There are steps you can take to help prevent vascular diseases:

• Make healthy lifestyle changes, such as eating a heart-healthy diet and getting more exercise
• Don't smoke. If you are already a smoker, talk to your health care provider for help in finding the best way for you to quit.
• Keep your blood pressure and cholesterol in check
• If you have diabetes, control your blood sugar
• Try not to sit or stand for up long periods of time. If you do need to sit all day, get up and move around every hour or so. If you traveling on a long trip, you can also wear compression stockings and regularly stretch your legs.
