Bone Fracture TypesSlide5
Transverse Fracture
A fracture straight across the bone, usually the result of sharp, direct blows or stress fractures caused by prolonged
running.
The
break occurs at a right angle to the bone’s long axis.Slide6
Spiral Fracture
A bone fracture caused by
a
twisting force.
Also
called torsion fracture.

Treatment Options
Fracture treatment depends on:
Location, fracture type
and its characteristics
The person’s age
The person’s activity level
Bone qualitySlide12
Nonsurgical Treatment OptionsSlide13
Surgical Treatment: External FixationSlide14
Internal vs. External FixationSlide15
Location of Fracture
Which bones are more likely to break?
Ribs, wrists, fingers, toes, collarbones
Why are certain bones more likely to fracture?
The body is designed to
withstand forces.
Legs receive impact while
walking and jumping.
Thus, leg bones require a
significant amount of force
to break.Slide16
How Does Treatment Depend on Location?
Certain treatments cannot be used on some fractures due to the location.
For example:
Casts cannot be used on all parts of the body,
such as moving joints.
Finger or toes are often treated by using a
nearby finger or toe as splint.
The forces the body withstands at certain locations allows some treatments.
