Topic Overview
Minor arm injuries are common. Symptoms often develop from everyday
wear and tear, overuse, or an injury. Arm injuries are often caused by:
- Sports or hobbies.
- Work-related tasks.
- Work or projects around the home.
Your child may injure his or her arm during sports or play
or from accidental falls. Chances of having an injury is higher in contact
sports, such as wrestling, football, or soccer, and high-speed sports, such as
biking, in-line skating, skiing, snowboarding, and skateboarding. Forearms,
wrists, hands, and fingers are the injured most often. An injury to the end of
a long bone near a joint may harm the growth plate and needs to be checked by a
doctor.
Older adults have a greater chance for injuries and broken bones because
they lose muscle mass and bone strength (osteoporosis)
as they age. Older adults also have more problems with vision and balance,
which increases their chances of having an accidental injury.
Most
minor injuries will heal on their own, and home treatment is usually all that
is needed to relieve symptoms and promote healing.
Acute injuries
Acute injuries come on suddenly and
may be caused by a direct blow, a penetrating injury, or a fall or from
twisting, jerking, jamming, or bending a limb abnormally. Pain may be sudden
and severe. Bruising and swelling may develop soon after the injury. Acute
injuries usually require prompt medical evaluation and may include:
- Bruises (contusions
), which occur when small blood vessels
under the skin tear or rupture, often from a twist, bump, or fall. Blood leaks
into tissues under the skin and causes a black-and-blue color that often turns
purple, red, yellow, and green as the bruise heals. - Injuries to the tough, ropelike fibers (ligaments) that connect
bone to bone and help stabilize joints (sprains).
- Injuries to the tough, ropelike fibers that connect muscle to
bone (tendons).
- Pulled muscles (strains).
- Muscle ruptures, such as a biceps or triceps rupture.
- Broken bones (fractures). A break may occur when a
bone is twisted, struck directly, or used to brace against a fall. See a
picture of a
fractured arm
. - Pulling or pushing bones out of their normal relationship to
the other bones that make up a joint (dislocations).
Overuse injuries
Overuse injuries occur when
stress is placed on a joint or other tissue, often by "overdoing" an activity
or repeating the same activity. Overuse injuries include:
- Pain and swelling of the sac of fluid that cushions and
lubricates the joint area between one bone and another bone, a tendon, or the
skin (bursitis).
- Pain and swelling of the tough, ropelike fibers that connect
muscles to bones (tendinitis).
- Pain and swelling from tiny tears (microtears) in the
connective tissue in or around the tendon (tendinosis). Other symptoms of this
type of tendon injury include loss of strength or movement in the arm.
- Hairline cracks in bones of the arm (stress fractures).
- Pressure on nerves in the arm, such as
carpal tunnel syndrome.
Treatment
Treatment for an arm injury may include
first aid measures (such as using a brace, splint, or cast), "setting" a broken
bone or returning a dislocated joint to its normal position, physical therapy,
medicines, and in some cases surgery. Treatment depends on:
- The location, type, and severity of the injury.
- When the injury occurred.
- Your age, health condition, and activities (such as work,
sports, or hobbies).
