behavioral factor that can 1) Age: bone structure becomes less dense/more
predispose a patient to a fracture. susceptible to injury
2) Type of bone involved: some are better
equipped to handle difference stresses and
forces without injury
Extrinsic:
1) Amount of force applied
2) Angle of force applied
3) Duration of force
Behavioral:
1) Participating in adrenalin-seeking activities such
as skydiving, rock-climbing, motor cross

may be given to a patient in a cast. 2) Monitor the skin areas at the end of the cast.
3) Never stick anything into or under the cast to
scratch or itch.
4) Alert medical care in case of tightness or
increasing pain, numbness, color change, or
temperature change in areas of distal ends of
cast.
5) Follow up if cast gets loose or cracks.
What is the basic anatomy of a long Typically has two main components:
bone? 1) Diaphysis - makes up long shaft of bone. Outer
portion is made of compact bone. Inner layer is
made of marrow.
2) Epiphyses - set at either end of long bone.
Outer layer is compact bone and inner core is
spongy bone.
Periosteum - membrane that lines both
externally. - contains supply of nerve fibers,
lymph, blood vessels
Give examples of tapping fracture 1) Tapping - sustained from a small force to a
and penetrating fracture. concentrated area. Bone will absorb this force -
may or may not be mild soft tissue display of
injury.
EX: fracture of forearm when blocking a hit with a
fist or bat; being kicked in lower leg
2) Penetrating - caused by large amount of force
on small area. Object of force is usually small and
soft tissue involvement is minimal.
EX: stab wound, gunshot wound
Different from crush wound because object of
force is much larger.
, List several factor that determine 1) Skeletal maturity decreases healing.
fracture-healing outcome. - Immature skeleton increases rate and success
of healing.
2) Single bone fracture has better prognosis than
multi-bone fracture.
3) Big displacement that affect surrounding
tissues requires more healing time.
4) Thoracic spine injury heals better than unstable
lumbar/cervical spine injuries.
5) Fracture of joint surfaces are more
unstable/difficult to treat.
6) Fracture with nearby unaffected support bone
has good prognosis - acts as natural splint.
Differentiate between linear, LINEAR: the fracture forms a straight line through
oblique, and transverse fractures. the bone; doesn't tell if fracture line is angled or
horizontal; a linear can be oblique or transverse
OBLIQUE: fracture line that travels at an angle
through the bone
TRANSVERSE: break that travels in a horizontal
line through the bone.
Don't ever just say a fracture line is linear -
differentiate with oblique or transverse.
