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
- Broken bones
- Nerve problems
You may also have problems or injure specific parts of your arm, such as your hand, wrist, elbow, or shoulder.
A fracture is a break, usually in a bone. If the broken bone punctures the skin, it is called an open or compound fracture. Fractures commonly happen because of car accidents, falls, or sports injuries. Other causes are low bone density and osteoporosis, which cause weakening of the bones. Overuse can cause stress fractures, which are very small cracks in the bone.
Symptoms of a fracture are
- Intense pain
- Deformity - the limb looks out of place
- Swelling, bruising, or tenderness around the injury
- Numbness and tingling
- Problems moving a limb
You need to get medical care right away for any fracture. An x-ray can tell if your bone is broken. You may need to wear a cast or splint. Sometimes you need surgery to put in plates, pins or screws to keep the bone in place.
Osteoporosis is a disease that thins and weakens the bones. Your bones become fragile and 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
- Getting older
- Being small and thin
- Having a family history of osteoporosis
- Taking certain medicines
- Being a white or Asian woman
- Having low bone density
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.
