Damage control orthopedics (DCO) is an approach for treating severely injured polytrauma patients to avoid worsening their unstable condition from additional surgical stress. It involves early stabilization of fractures through temporary external or minimal internal fixation to be followed later by definitive treatment after the patient's physiology is stabilized. While early total care was previously favored, DCO is now widely accepted for polytrauma patients as it decreases systemic complications by limiting the "second hit" effect compared to prolonged definitive surgeries. The approach and timing of DCO versus early total care must be individualized based on the patient's clinical status and injury pattern.

35. TAKE HOME MESSAGE
FRACTURE ALWAYS HAS A PATIENT ATTACHEDTO IT!
Damage Control Orthopedics is a highly evolving topic, that has been changing
the management of polytrauma patients throughout the decades.
Damage Control Orthopedics is a part of the Resuscitation process
It has been shown to save lives
Safe definitive surgery is a new concept, that puts both ETC and DCO in
prospective of the clinical condition of the patient.
The Term “Damage Control” was derived from the US NAVY term, which was used during the end of WWII, when the Japanese airforce bombed the pearl harbour.
It meant…(click)
Polytraumatic conditions are frequently life-threatening situations that require a special approach.
The management of severely injured patient with fractures has changed over the last decades
In the early 70s long bone fractures were mainly stabilized by traction (1). This concept was associated with numerous complications such as pulmonary infections, atrophy of the musculature and thromboembolic complications due to prolonged immobilization
During that time, most patients who had poly trauma, usually had hemodynamic instability and eventually die
And Early definitive treatment was performed on those few exceptions who did not die.
In the late 70s and early 80, the First meaningful study was published in 1977, showing that early, definitive stabilization of long bone fractures reduced the incidence of the fat embolism syndrome compared to traditional non-surgical treatment
And also in 1985, another article concluded that there was A significant increase in ARDS associated with a delay in fracture stabilization in patients with multiple injuries.
Bone ET AL published a prospective randomized study and compared the clinical outcome after early (< 24 hours) and delayed (> 48 hours) femoral fracture fixation. This was a land-mark publication FOR early total care strategy.
Which showed that Early total care was associated with
less pulmonary complications and
reduced lCU and hospital stay and
And Early fracture fixation resulted in
early mobilization,
avoided nutritional depletion and long drug therapy and
reduced wound infections
Thus, ETC had become a standard approach in polytrauma in the 80s and early 90s.
This strategy was further stimulated by advances of osteosynthesis techniques and implants over these decades. (click)
Hence, the surgeons at the time, religiously followed the principal of Thou shalt immediately FIX ALL fractures, AND IT WAS CALL EARLY TOTAL CARE
THEN CAME THE 90S ERA: Several authors, challenged the Dogma and criticized that early fixation might be detrimental for several patient groups.
This method of combined surgical procedures may lead to development of an additional, secondary life-threatening inflammatory response reaction, which can cause an excessive inflammatory reaction known as the <click> "second hit"
Then the damage control orthopedics was born.
Damage control orthopedics which deals with poly trauma has a specific definition, known as the berlin definition, which was proposed in 2014
According to this, polytrauma is defined as..
THE PRINCIPLE…
In a patient with polytrauma, because of the <click> actions of the cytokines, leukocytes, endothelial changes, FREE OXYGEN RADICALS, eicosanoidsand and microcircularatory disturbances with the sub-sequent leukocyte-endothelial cell interactions there is inevitably a <click> Systemic inflammatory response syndrome, going on in the body.
Naturally, <click> there is a gradual recovery of the normal physiology of the body after around 5 days with the fall in level of inflammatory mediators, mainly the IL-6 and IL-8, because of the Counter regulatory anti inflammatory response syndrome.<click>
The balance between Counter regulatory anti inflammatory response and Systemic inflammatory response maintains the homeostasis of the body. When the effects of inflammation increases, the SIR is high which needs to brought back to normal by the action of Counter regulatory anti inflammatory response, which takes some time depending upon the severity of the injury.
If the first hit itself is severe enough, the CARS may not be able to bring back homeostasis eventually leading to multi organ failure, even without second hit. However, in most cases, homeostasis is eventually maintained. <click>
Several authors have demonstrated the immunosuppressive effect of trauma. Where there is decrease in the production of immunoglobulins and interferon and many patients thus have an increased risk of infections and of posttraumatic sepsis
With these physiological and pathological changes happening in the body<click> with Early Total Care in these unstable patients, there may be a significant increase the severity of this systemic inflammatory response (SIRS) and may lead to <click> development of acute respiratory distress syndrome (ARDS) and <click> subsequently multiple organ failure (MOF), carrying a relatively high incidence of morbidity and <click> mortality
IL-1, IL-6, IL-8, TNF-α, Procalcitonin and C-reactive protein, has been frequenty used for evaluating the inflammatory reaction in the body however, markers other than IL6 has not been shown to be reliable markers.
There may also be genetic predisposition to development of complications following trauma
Polymorphism of the neutrophil receptor, mainly for IgG and CD16
Mutations of Cytokine genes, mainly of TNF ,IL6 and IL10
And Microsatellites polymorphism has been found to be related to hyperreactivity to trauma
If these gene mutations could be identified early, it may indicate the patient at risk of complications and help in clinical decision making
Damage control orthopedics is widely accepted for the treatment of severely injured patients.
However, there is a need to differentiate between
those who can withstand prolonged surgical procedures and the following body response and
those who cannot
There are many scoring scales for trauma patients, like Abbreviated Injury scale, ISS, GCS., that help in stratifying these patients.
And patient are classified in 4 categories
Stable, unstable and in Extremis patients are fairly easy to be differentiated, however, there may be a large gap between stable and unstable categories, within which lies the borderline patients
The borderline patient is defined as patients with either one
The hanover management protocol has been proposed for the management of patients in different categories.
Coming to the management of patients,
Damage control orthopedics should be considered as the part of the resuscitation process.
ABC of the patient is examined and managed as required
Fluid resuscitation is usually required,
However, there is controversy between infusion of Crystalloids and colloids. Infusion of Crystalloids has been associated with high volume requirement for replenishment and associated with development of ARDS in the future, whereas colloids are associated with more immediate complications such as allergic and incompatibility reactions.
Imaging is done if necessary once the patient is hemodynamically stable
DOES NOT PROVIDE optimal time for surgery as the body is undergoing intense response to primary trauma, AS MARKED IMMUNE AND INFLAMMATORY REACTIONS ARE GOING ON IN THE BODY
Day 5-14 is the safe period for procedure, provided that the patient is hemodynamically stable.
Even if patient has high ISS there is a significant reduction in the incidence of general systemic complications (ARDS, MOF)
DCO was not associated with any increased rate of local complications such as pintract infections, delayed unions or non-unions.
The external fixation used to stabilize the fracture does not induce significant inflammatory response
Femur fractures with Polytrauma are automatically not treated with IM Nails because of its association with multiple complications and bilateral femoral nailing has even higher rate mobidity and mortality to its credit.
Waiting for a few days ideal in these patients and until then, fractures can be stabilized with External fixating devices, followed by ORIF with Plating or if patient is then stable enough , <click> IMIL can be considered
Fractures of the Pelvis is frequently associated with excessive hemorrhages, therefore damage control surgery for control of hemorrhage may be needed.
Bleeding can be osseous, venous, arterial or a combination of any.
Pelvic binders used in the ER, helps in stabilizing the pelvis, however, it may give a false picture producing a misleading Xray, by decreasing pelvic volume, realigning pelvis and producing benign looking Xray
For treatment, control of hemorrhage: can be minimally invasive by interventional radiology and embolization or by open surgery.
Some author advocate definitive surgery by plating if open surgery is required for controlling hemorrhage
Otherwise pelvis can be stabilized with use of Ganz Pelvis Clamp, External fixator
Geriatric patient require specialized care because of higher mortality associated with age in trauma.
The choice between ETC and DCO in patient with thoracic injury is still controversial.
However, it has been noted that there has been no RCTs available for the treatment of polytrauma with chest injury
A comparision of available study found similar rates of mortality, ARDS, mechanical ventilator requirements, length of ICU stay and hospital stay between patient undergoing ETC within 48 hours and patient undergoing DCO and definitive surgery later
NO RCT available regarding treatment in cases of head injury
Based on the available studies, outcomes were found to be similar in polytrauma cases with long bone fracture along with mild, moderate or severe head injury undergoing early total care within the first 48 hours and definitive surgery later on.
Low extremity assessment project or LEAP study
The use of
spanning external fixation,
antibiotic bead pouches, and
the vacuum-assisted wound closure technique
may provide a bridge to staged osseous reconstruction and soft-tissue coverage procedures
This table shows the number of patients who developed ARDS amongst those who underwent different modalities of definitive management in different time period. ETC time period is from time of trauma to 48 hours. Intermediate period is from 2 to 4 days and DCO period is from 5 to 14 days
You can see that the least percentage of ARDS in all three time period, is found in patient who undergo Primary external fixation and secondary IM nailing
This article, published by Pape, in 2015. gives the concept of Safe definitive orthopedic surgery. The author was one of the strongest advocate of DCO in the 2000s era with multiple articles supporting DCO was published.
