subluxation
Discoloration of the skin associated with a closed wound; bruising.
ecchymosis
A bandage or material that helps to support the weight of an injured upper extremity.
sling

acromioclavicular (AC) joint
The heel bone.
calcaneus
The area of potentially damaged soft tissue, adjacent nerves, and blood vessels surrounding an injury to a bone or a joint.
zone of injury
Used to splint the bony pelvis to reduce hemorrhage from bone ends, venous disruption, and pain.
pelvic binders
A fracture in which bone fragments are separated from one another and not in anatomic alignment.
displaced fracture
The outer and smaller bone of the bones of the lower leg.
fibula
A simple crack in the bone that has not caused the bone to move from its normal anatomic position; also called a hairline fracture.
nondisplaced fracture
The part of the scapula that joins with the humeral head to form the glenohumeral joint.
glenoid fossa

sprain
The space between the abdominal cavity and the posterior abdominal wall, containing the kidneys, certain large vessels, and part of the gastrointestinal tract.

The bleeding control method used when a wound continues to bleed despite the use of direct pressure and elevation; useful if a patient is bleeding severely from a partial or complete amputation.
tourniquet
Blood in the urine.
hematuria
Swelling in a confined space that produces dangerous pressure; may cut off blood flow or damage sensitive tissue; frequently seen in fractures below the elbow or knee in children.
compartment syndrome
Return a dislocated joint or fractured bone to its normal position; set.
reduce

open fracture
A hand position in which the wrist is slightly dorsiflexed and all finger joints are moderately flexed.
position of function

tibia
Stretching or tearing of a muscle; also called a muscle pull.
strain
A flexible or rigid appliance used to protect and maintain the position of an injured extremity.
splint
The place where two bones come into contact.
joint
A pearly layer of specialized cartilage covering the articular surfaces (contact surfaces on the ends) of bones in synovial joints.
articular cartilage
Longitudinal force applied to a structure.
traction
Disruption of a joint in which ligaments are damaged and the bone ends are completely displaced.
dislocation
A grating or grinding sensation caused by fractured bone ends or joints rubbing together; also air bubbles under the skin that produce a crackling sound or crinkly feeling.
