List several factor that determine fracture-healing
outcome. - Answer-1) Skeletal maturity decreases healing.
- 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, oblique, and transverse
fractures. - Answer-LINEAR: the fracture forms a straight

line through 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.
Describe/give examples of following bony injuries. -
Answer-1) CRUSH - caused by large stress on a small
area; results in multiple break lines and severe soft tissue
damage; EX: sledgehammer coming down on a finger or
heavy suspended mass falling on foot or leg
2) COMPRESSION - happens with large axial loading
force; most often in vertebrae; EX: landing on feet or butt,
fall from a moderate height

3) STRESS - not sustained by one-time incident but
instead with repetitive activity that stresses a normal bone
over time
Differences between plaster of Paris and fiberglass
casting. - Answer-PLASTER OF PARIS: slightly cheaper,
molds well but is heavier and has longer drying
time/setting; not ideal for kids in an outpatient
setting/upper extremity injury
FIBERGLASS: more expensive, comes in different colors,
molds well, lightweight, drying time is as little as 5
minutes, more water resistant; BUT edges are more
abrasive and they tend to be hotter
How to choose? - cost, physician comfort/familiarity, joint
being immobilized, injury being treated & patient type
Discuss the 4 main types of bone. - Answer-1) LONG
BONE: longer than they are wide; consist of shaft
(diaphysis) and head (epiphysis); EX: humerus, femur
, 4|Page
2) SHORT BONE: cubical in shape; consist of spongy
bone; EX: carpals in wrist
3) FLAT BONE: thin and flat with slight curvature; contain
mostly compact bone; EX: skull bones
4) IRREGULAR BONE: don't fit above classifications;
consist of spongy bone with thin compact outer layer; EX:
vertebrae, pelvic girdle bones
Describe angulation and rotational fractures. - Answer-
ANGULATION FX: force that causes bony fragment to
become broken transversely, then misaligned; usually in a
v shape; EX: same as that of a tapping force, like using
forearm to block a blow
ROTATIONAL FX: force causes a spiraling fracture line;
seen in arms or lower leg - when seen in child, raises
question of abuse
Name 2 biological, 3 extrinsic, and 1 behavioral factor that
can predispose a patient to a fracture. - Answer-Biological:
1) Age: bone structure becomes less dense/more
susceptible to injury
