Chapter 15Extremity Injuries
Extremity Injuries
Injuries to the extremities are common because people are involved in active lifestyles that include sports and wilderness activities.
Extremity Injury Assessment• Look for signs and symptoms of fractures
and dislocations.• Examine the extremities using DOTS. • Compare one extremity with the other.• Use the “rule of thirds.”• Consider the cause of injury. • Use CSM (circulation, sensation,
movement).
Types of Extremity Injuries (1 of 2)
• Contusions—occur when tissue is bruised• Strains—occur when the muscles are
stretched or torn • Sprains—involve tearing or stretching of
joints, causing damage to the ligaments and joint capsules
Types of Extremity Injuries (2 of 2)
• Tendinitis—inflammation of a tendon caused by overuse
• Dislocations—occur when bones are displaced from their normal joint alignment, out of their sockets, or out of their normal positions
• Fractures—breaks in bones that may or may not be accompanied by open wounds
Care for Extremity Injuries
• Use RICE procedures.• Apply a splint to stabilize
fractures and dislocations.
RICE Procedures (1 of 7) • Acronym for rest, ice, compression, and
elevation • Recommended immediate treatment for
bone, joint, and muscle injuries • The first 48 to 72 hours after an injury
can do a lot to relieve—and even prevent—aches and pains.
RICE Procedures (2 of 7)
• R = Rest• Do not use or move injured part.• Crutches may be used.
RICE Procedures (3 of 7)
• I = Ice• Apply for 20 to 30 minutes.• Apply as often as possible.• Do not apply directly to skin.• If skin becomes numb, remove.
RICE Procedures (4 of 7)
• C = Compression• Apply elastic
bandage to injury.• Should be worn
continuously for first 18 to 24 hours
• Use horseshoe-shaped pad for ankle injury.
RICE Procedures (5 of 7)
• E = Elevation• Limits circulation to injured area
• Limits internal bleeding; minimizes swelling• Do not elevate a suspected fracture until it has
been stabilized.
RICE Procedures (6 of 7) • R = Rest• I = Ice
• Apply for 20 to 30 minutes.
RICE Procedures (7 of 7)
• C = Compression• Apply a compression
bandage for 3 to 4 hours.
• E = Elevation• Raise the injured area
higher than the heart.
Shoulder Dislocation
• Occurs when shoulder bones come apart• Result of a blow or a particular movement
• Second in frequency only to finger dislocations
Recognizing a Shoulder Dislocation (1 of 2)
• Victim holds upper arm away from body.• Arm cannot be brought across chest.• Extreme pain in the shoulder area• Shoulder appears squared off.
Recognizing a Shoulder Dislocation (2 of 2)
• Injury results in complete loss of function.• History of previous dislocations• Numbness or paralysis in the arm
Care for a Shoulder Dislocation• Do not force, twist, or pull back in place.• Place a folded or rolled blanket or pillow
between upper arm and chest. • Apply an arm sling and swathe.• Apply an ice pack for 20 minutes.• Seek immediate medical care.
Clavicle Fracture• Common• Usually result of falling with arm
and hand outstretched• Most occur in the middle third of
the bone.
Recognizing a Clavicle Fracture (1 of 2)
• Deformity• Fell on outstretched arm• Direct blow to clavicle or shoulder• Severe pain over injured area• Holding injured arm against chest

• Apply an ice pack: • 20 minutes, three to four times during first
24 hours• Place arm in sling and swathe.
• One end tucked between arm and body • Ties in back
Tendinitis
• Inflammation of the shoulder• Result of continuous overuse
or unusual use
Recognizing Tendinitis• Constant pain or pain with
motion of the shoulder• Limited motion of shoulder• “Crackling” sound• Tenderness over the area
Care for Tendinitis• Use an ice massage for 10
minutes before and after exercise.• Use a sling and swathe.• Use pain medication.• Seek medical advice.
Humerus Fracture• Shaft of the humerus can be felt
throughout its entire length along inner side of upper arm.
Recognizing a Humerus Fracture• Direct blow to the area• Twist or fall on the outstretched arm• Severe pain and swelling• Deformity• Tender if touched• Inability to move the arm• Holds arm against chest
Care for a Humerus Fracture

Care for Splinters• Use tweezers to remove it. • If splinter is impaled under a nail and
breaks off flesh: • Cut a V-shaped notch in the nail.
• Remove with tweezers.
Blood Under a Nail
• Blood collects under a nail when underlying tissues are bruised.

free.• Take anti-inflammatory pain
medications.
Ankle and Foot Injuries
• Frequently injured by twisting• Stretches or tears ligaments
• Most ankle injuries are sprains that involve the outside ligaments.
Recognizing Foot and Ankle Injuries (1 of 2)
• Two-part test to determine whether an X-ray is needed:• Press along the bones.
• Pain and tenderness may indicate a broken bone.
• Have the victim try to stand on it. • Ability to take four or more steps is most
likely a sprain.• Inability to walk on it may indicate a break.
