Orthopaedic Trauma
The first 15 min……..
The Basics
10% of blunt trauma have a missed injury
Difficult environment
Difficult to assess
To avoid
Systemic head-to-toe examination
Assess pelvis and palpate all long bones
Active or Passive ROM all joints
Careful Neurovascular exam of each limb
If it is swollen – image it
The Basics
Appropriate resuscitation
Pelvis - > 2 L
Femur fracture – 1 - 1.5 L
Tibia – 400 - 700 cc
Humerus – 200 - 500 mL
Method of Maull for estimating blood loss
Outline
Femoral neck fractures
The Pelvic Fracture
The Pelvic Fracture
High energy, consider associated injuries
Assess
History for mechanism
Pelvic stability (once)
?urethral bleeding, rectal blood, vaginal
bleeding, high riding prostate
DNVS +
Radiography
Pelvic Stability
Intrapelvic Contents
bladder
urethra
vagina
rectum
Instability: Implications
High vs. Low Energy Injuries
Radiographs: AP
most information
Sufficient to determine stability for resusc

Approach
Stabilize Pelvis
Sheet
Beanbag
+/- traction
Work up urethral/bladder
injuries
Retrograde urethrogram,
cystogram
If blood in the
rectum/vagina, treat as
open
Look for blush on CT scan
If remains unstable
ER rotation injuries to the
OR
IR rotation injuries or
fractures into the sciatic
notch – consider
angiography
Pelvic fracture
Definitive management
If stable
Ex-fix or definitive management
If unstable
Ex-fix, laparotomy prn, angiography, packing prn
If open
I&D, stabilize, diverting colostomy, urethral/vaginal
management, soft tissue closures
Acute Dysvascular limb
Signs and symptoms
Colour or pulse asymmetry
Rapid pulsatile blood loss
Any difference in pulses needs to be explained (not
all 5 Ps present)
Early consult
Angiogram rarely required (unless potential for 2 level
injury)
Delays treatment 2-3 hrs
If required, on the table angiogram
Acute Dysvascular limb
Realistic approach
Attempts to salvage are not without risk
Acute amputation
morbidity rate approach 0%
Salvage
5 - 20% mortality
Multiple surgeries, drug addiction, divorce
80% left with significant disabilities
Acute Dysvascular limb
Approach
Correct Deformity and reassess DNVS
Perform ABI – ankle brachial index
>0.9 – monitor with repeated exams
< 0.9 - vascular consult, angiogram
If bleeding
Direct pressure
Tourniquet
Clamp (snap)
Treat like an open fracture – I&D,
antibiotics, tetanus
Acute Dysvascular limb
Consider
? period of ischemia
if > 6-8 hr then fasciotomies
? risk of compartment syndrome
Definitive management approach
Urgent OR
Bone stabilization – ex-fix, nail
Vascular repair/bypass
Fascitomies if > 6-8 hrs
Definitive Bone fixation
Compartment Syndrome
Diagnosis
Index of suspicion
Crush injury (forearm, leg)
Vascular injury
5 Ps
Pain out of proportion, pulseless, palor,
parathesias, paralysis
Pressures
art line
Controversial, but if within 20 mm Hg of diastolic BP it
requires release
Treatment
Urgent release within 6 hrs of injury
Long incisions, complete release
Compartment Syndrome
Spine Injuries
ADI < 4mm
Soft tissue swelling
5 mm, 21 mm
Less than 3 mm
subluxation
4 lines
Spine injuries
Define level
Asia scale to define
motor and sensory

!! Document and
reassess !!!
Spine Injuries
Shock
Hemorrhagic
Low BP, tachycardia, narrow pulse pressure
Tx – fluid resusc
Neurogenic
Low BP, lack of tachycardia, widened pulse pressure
Initial fluid resusc
Spinal shock
Bulbocavernosus reflex 1st to return
Pull foley, pinch glans/clitoris
Spine Injuries
Treatment
Stabilize
Role of solumedrol
Controversial
3m mg/Kg then 5.4 mg/kg/hr x 48 hrs
Timing of reduction
If complete – stabilize patient completely
If incomplete
Ensure no disc if C spine disclocation
Early reduction and decompression to avoid secondary injury
Hip dislocations
Usually high energy
Hip Dislocations
Hip Dislocations
Posterior Hip Dislocation
95% of presentations
Flexion, adduction, IR, shortening
Reduce
Appropriate sedation
++ flexion, traction, IR/ER
Anterior Hip dislocations
Rare
ER, extension
Reduce
Appropriate sedation
In-line traction, lateral traction, IR
Traumatic hip fracture
Sciatic nerve injury in 20% of posterior
dislocations

The Open Fracture
Ensure DNVS
Consider degree of contamination and soft tissue
involvement
Gustilo and Anderson:
Grade 1:
Grade 2:
Grade 3:
Grade 3:
Grade 3:
< 1cm (Ancef)
>1cm – 10cm (Ancef/Gent)
(a) high energy, gross contamination (add penicillin)
(b) soft tissue loss requiring graft/flap
(c) vascular injury
Ensure Tetanus up to date
The Open fracture
Gentle I&D at time of reduction
Don’t worry about risk of contamination with reduction
Cover with wet gauze and splint
Book for OR (within 8)
Definitive
I&D
ORIF +/- repeat I&D at 48 hrs
If gross contam – I&D + ex-fix, repeat I&D until ready
for fixation definitive
The Closed Fracture/Dislocation
Preferable to have an injury film
Exam joint above and below
DNVS – Document!!!
Prepare to reduce
Reduction and splinting
Reduces pain and swelling
May restore blood flow to region
Reduces skin complications
Temporizes
Treatment Timing
ETC vs DCO
Early Total care
Goals
Minimize blood loss
Minimize mediator release
Improve pulmonary function
Decrease sepsis and pain
Shorten LOS and expense
Problems
High ISS = High risk of ARDS
Especially if severe chest injuries, severe shock or
coagulopathy (Pape 1993)
Treatment Timing
ETC vs DCO
Damage control Orthopaedics
Goals
Fast hemodynamic and orthopaedic stabilization
Avoid pulmonary complications and SIRS
Problems
Prolongs treatment period ‘miss your opportunity’
Controversy Continued:
Early skeletal fixation is appropriate but
what are the limits in patients with :
Hemodynamic instability ?
Coagulopathy ?
Hypothermia ?
Severe head or chest injury ?
= SHOCK
How to Identify The “Borderline
Patient”
Coagulopathy
platelets < 90K
>25 U RBC
Cold: Temp. < 32
Inadequate resuscitation
pH < 7.2, Base excess > 10,
Bilateral Lung contusions
Probable OR time >6 hrs
Multiple Long bones plus truncal AIS >2
High Inflammatory Markers
IL-6, IL-1β, TNF- α
Correlates with ISS
Rise with Trauma and 2nd ORIF Hit
Once the Patient at Risk is
Identified . . .
Damage Control
Mode
Provisional stabilization
with Rapid External
Fixation
Patient in Shock
Multiply injured patient
Physiologically unstable
Severe chest injury
(pulmonary insufficiency)
Severe TBI (Hemorrhage or
elevated ICP)
DAMAGE CONTROL ORTHOPAEDICS
Staged Intramedullary Nailing
After Physiologic Stabilization
Timing - SUMMARY
THE GOLD STANDARD:
Early stabilization (<24 hrs) of long
bone fractures in multiply injured
patients.
For most patients who are
physiologically stable, reamed IM
nailing is the procedure of choice.
Timing - SUMMARY
In “borderline” patients, who are
physiologically unstable because of severe
chest or head injury OR inadequate
resuscitation, temporizing external fixation
- “damage control orthopaedics” may be
advantageous.
Definition of “Borderline” patients
continues to evolve
