8. An approach that contains and stabilizes orthopaedic injuries so
that the patient’s overall physiology can improve.
DCO should be regarded as a part of the resuscitation process
11. The 24-72 hour period after the initial injury appears to be the most at-risk time
Stabilize fractures and bleeding
Decrease the chance
prior to the 24-72 hour high-risk
of a second hit
period.
12. Till 1970s - 80s
Multiply injured patients were too unstable to survive surgical intervention.
Early definitive fracture stabilization was
performed only as an exception
Signs of MODS in the first posttraumatic week was
diagnosed as the ‘‘fat embolism syndrome’’,
characterised by hypoxia, cerebral depression
(somnolence, coma), coagulopathy (petechial
bleeding) or renal failure (anuria).
Surgical fracture stabilization were only performed in
patients, who were in a condition, i.e. without signs
of fat embolism syndrome.
13. Stabilization within 24 h, Aggressive Resuscitation
1980s
First meaningful study published, showing that early, definitive stabilization of long
bone fractures reduced the incidence of the fat embolism syndrome compared to
traditional non-surgical treatment.

A significant increase in ARDS associated with a delay in fracture stabilization in
patients with multiple injuries
• Increasingly significant in ISS > 40
Johnson K.: J Trauma 25(5): 1980
Early femoral fracture fixation in the multiple trauma patient resulted in
statistically significant improvement in the rates of survival

‘Borderline patient’
At particular risk
of late, poor outcome.
Patients with a very high ISS did not appear to benefit from ETC
15. CLINICAL EXAMPLE
16 y male, RTA
• Pulmonary Contusions
• Stable TBI
• Bilateral Femoral #
• Hip Dislocation
ETC – BL Femoral Nailing
16. CLINICAL EXAMPLE
96 h post femoral nailing
Florid ARDS
Outcome at 01 wk
Autopsy
IS IT INEVITABLE?
OR PREVENTABLE ?
17. Life as a trauma surgeon would be easy
if all we had to deal with was the fracture. COMPLICATING FACTORS
The fracture always has a patient
attached to it.
This forces us to consider more than just
the bones.
18. Clinical Parameters Used in Hannover, Germany, to Define the “Borderline” Patient for
Whom DCO Is Often Preferred
Polytrauma + ISS >20 + Thoracic trauma
Polytrauma + Abdominal/pelvic trauma + Hemorrhagic shock (initial BP <90 mm Hg)
ISS ≥ 40 in the absence of additional thoracic injury
X Ray: B/L lung contusion
Initial mean pulmonary arterial pressure >24 mm Hg
Increase of >6 mm Hg in pulmonary arterial pressure during IM Nailing

28. Days 2—4 do not offer optimal conditions for definitive surgery.
Primary procedures of greater than 6 h duration and major surgical procedures at
days 2—4 should be avoided.
Between 5 – 14 days post injury
33. Prolonged operation could cause intraop
hypotension, hypoxia, coagulopathy, increased
blood loss and fluid requirements during and
after the orthopedic operation.
DCO – EXTERNAL FIXATION
This will be detrimental to cerebral perfusion and
would be an additional insult to the already
injured brain, thus outweighing the benefits of
early fracture stabilization.
Maintenance of CPP >70 mm Hg and ICP <20 mm Hg should be mandatory before,
during, and after surgical procedures.
34. LEAP Study
An increasing trend toward limb salvage
rather than immediate amputation for
complex open lower-extremity injuries.
A DCO approach to saving the limb
Spanning external fixation,
Antibiotic bead pouches
Vacuum-assisted wound closure
35. An isolated complex extremity injury (other than a mangled limb)
Complex proximal tibial fractures
Distal tibial pilon fractures.

37. CURRENT ISSUES
Early skeletal fixation is appropriate…
• But what are the limits ?
• Hemodynamic instability
• Pulmonary instability
• Severe head injury
• Coagulopathy
• Hypothermia
38. DCO: Principles in Polytrauma
Ortho team must be
resuscitators and stabilizers:
not “fixers”
