Fractures - General
Principles
·
closed: skin/soft tissue over and near fracture is
intact
·
open: akin/soft tissue over and near fracture is
lacerated or abraded, fracture exposed to outside environment. continuous
bleeding from puncture sl1e or fat droplets in blood suggest communication with
fracture
·
epiphyseal: end of bone, forming part of the adjacent
joint
·
metaphyseal: the flared portion of the bone at the
ends of the shaft.
·
diaphyseal: the shaft of a long bone (proximal,
middle, distal)
·
physis: growth plate
·
transverse: perpendicular fracture line, direct
force, high energy
·
oblique: angular fracture line, angular or
rotational force
·
butterfly: slight comminution at the fracture site
which looks like a butterfly
·
segmental: a separate segment of bone bordered by
fracture lines, high energy
·
spiral: complex, multi-planar fracture line,
rotational force, low energy
·
comminuted/multl-fragmenary: more than 2 fracture
fragments
·
intra-articular: fracture line crosses artlcu1ar
cartilage and enters joint
·
compression/Impacted: impaction of bone, e.g.
vertebrae, proximal. tibia
·
torus: a buckle fracture of one cortex. often in
children (Figure 49)
·
green-stick: an incomplete fracture of one cortex,
often in children (Figure 49)
·
pathologic: fracture through bone wakened by
disease/tumour
·
nondisplaced: fracture fragments are in anatomic
alignment
·
displaced: fracture fragments are not in anatomic
alignment
·
distracted: fracture fragments are separated by a
gap
·
angulated: direction of fracture apex. e.g.
varus/valgus
·
translated: percentage of overlapping bone at
fracture site
·
rotated: fracture fragment rotated about long axis
of bone
·
ABCs, primary survey and secondary survey (ATLS
protocol)
o
rule out other fractures/injuries
o
rule out open fracture
·
AMPLE history - Allergies, Medications, Past
medical history, Last meal, Events surrounding injury
o
consider pathologic fracture with history of only
minor trauma
·
additional history/physical:
o
baseline functional status -handedness (upper
extremity) vs. ambulatory ability (lower ertremity- note distances, stairs, and
use of assistive devices such as canes, walkers, wheelchairs, etc.)
o
occupation and smoking status
o
mechanism of injury
o
past medical history (note any contraindications to
or general anesthetic)
o
neurovascular status
·
analgesia
·
imaging
·
splint extremity
1. obtain
the .reduction (refer to Table 22 for appropriate IV sedation)
·
closed reduction
•
apply traction in the long am of the limb
•
reverse the mechanism that produced the fracture
•
reduce with IV sedation and muscle relaxation
(fluoroscopy can be used if available)
·
indications for open reduction - NO CAST
·
other indications include
•
failed closed reduction
•
cannot cast or apply traction due to site (e.g.
hip fracture)
•
pathologic fractures
•
potential fur improved function with open
reduction and Internal fiDtion (ORIF)
·
potential complications of open reductions
•
infection
•
mal-union
•
non-union
•
implant failure
•
new fracture
·
re-check. neurovascular status after .reduction
and obtain post-reduction x-ray
2.
maintain the reduction
·
external stabilization - splints, casts, traction,
external fixator
·
internal stabilization -percutaneous pinning, extra
rnedullary fixation (screws, plates, wires), intramedullary fixation (rods)
·
follow-up- evaluate bone healing
3.
rehabilitate to regain function and
avoid joint stiffness
·
clinical.: No longer tender to palpation or stressing
on physical exam
·
x-ray: trabeculae cross fracture site. visible
callus bridging site on at least 3 of 4 cortices
