Operative management of lower extremity fractures in patients with head injuries

Developments in the understanding of staging a "major fracture" in polytrauma: results from an initiative by the polytrauma section of ESTES

PURPOSE

Although the term "major fracture" is commonly used in the management of trauma patients, it is defined insufficiently to date. The polytrauma section of ESTES is trying to develop a more standardized use and a definition of the term. In this process, a standardized literature search was undertaken. We test the hypothesis that the understanding of "major fractures" has changed and is modified by a better understanding of patient physiology.

METHODS

A systematic literature search of the Medline and EMBASE databases was conducted in March 2022. Original studies that investigated surgical treatment strategies in polytraumatized patients with fractures were included: This included timing, sequence and type of operative treatment. A qualitative synthesis regarding the prevalence of anatomic regions of interest and core factors determining decision-making was performed. Data were stratified by decades.

RESULTS

4278 articles were identified. Of these, 74 were included for qualitative evaluation: 50 articles focused on one anatomic region, 24 investigated the relevance of multiple anatomic regions. Femur fractures were investigated most frequently (62) followed by pelvic (22), spinal (15) and tibial (15) fractures. Only femur (40), pelvic (5) and spinal (5) fractures were investigated in articles with one anatomic region of interest. Before 2010, most articles focused on long bone injuries. After 2010, fractures of pelvis and spine were cited more frequently. Additional determining factors for decision-making were covered in 67 studies. These included chest injuries (42), TBI (26), hemorrhagic shock (25) and other injury-specific factors (23). Articles before 2000 almost exclusively focused on chest injury and TBI, while shock and injury-specific factors (e.g., soft tissues, spinal cord injury, and abdominal trauma) became more relevant after 2000.

CONCLUSION

Over time, the way "major fractures" influenced surgical treatment strategies has changed notably. While femur fractures have long been the only focus, fixation of pelvic and spinal fractures have become more important over the last decade. In addition to the fracture location, associated conditions and injuries (chest trauma and head injuries) influence surgical decision-making as well. Hemodynamic stability and injury-specific factors (soft tissue injuries) have increased in importance over time.

Early versus late intramedullary nailing for traumatic femur fracture management: meta-analysis

INTRODUCTION

There is no consensus yet on the impact of timing of femur fracture (FF) internal fixation on the patient outcomes. This meta-analysis was conducted to evaluate the contemporary data in patients with traumatic FF undergoing intramedullary nail fixation (IMN).

METHODS

English language literature was searched with publication limits set from 1994 to 2016 using PubMed, Scopus, MEDLINE (OVID), EMBASE (OVID), Web of Science, and Cochrane Central Register of Controlled Trials (CENTRAL). Studies included randomized controlled trials (RCTs), prospective observational or retrospective cohort studies, and case-control studies comparing early versus late femoral shaft fractures IMN fixation. Variable times were used across studies to distinguish between early and late IMN, but 24 h was the most frequently used cutoff. The quality assessment of the reviewed studies was performed with two instruments. Observational studies were assessed with the Newcastle-Ottawa Quality Assessment Scale. RCTs were assessed with the Cochrane Risk of Bias Tool.

RESULTS

We have searched 1151 references. Screening of titles and abstracts eliminated 1098 references. We retrieved 53 articles for full-text screening, 15 of which met study eligibility criteria.

CONCLUSIONS

This meta-analysis addresses the utility of IMN in patients with FF based on the current evidence; however, the modality and timing to intervene remain controversial. While we find large pooled effects in favor of early IMN, for reasons discussed, we have little confidence in the effect estimate. Moreover, the available data do not fill all the gaps in this regard; therefore, a tailored algorithm for management of FF would be of value especially in polytrauma patients.

Increased risk of adverse events in management of femur and tibial shaft fractures with plating: An analysis of NSQIP data

BACKGROUND

The management of femoral and tibial shaft fractures has long been among the simplest in orthopaedic trauma. Little data exist on the predictors of complications associated with these fractures. The evolving healthcare system is creating a focus on quality metrics and changing payment models. It is critical that traumatologists develop a better understanding of complication rates associated with these injuries so that they may continue to improve patient care while also reducing overall medical costs.

METHODS

Using the ACS-NSQIP database, we evaluated patient demographics, comorbidities and 30-day complications of femoral and tibial fractures. A bivariate analysis was then used to compare rates of minor and major post-operative complications within 30 days. A multivariate logistic regression was performed, assessing the odds of developing a minor and/or major complication up to 30 days post-surgery.

RESULTS

2891 patients were identified. For femoral fractures, intramedullary nailing (IMN) demonstrated an overall complication rate of 14.9% (n = 151) whereas open reduction and internal fixation (ORIF) with plating showed an overall complication rate of 15.6% (n = 70). Patients undergoing plating of the femur or tibia were 2 times more likely than the IMN patients to demonstrate postoperative complications.

CONCLUSION

Our study is the first to demonstrate that plating of femoral and tibial fractures doubles the odds of developing a complication. As our healthcare system shifts to bundled payment plans, it is impertinent for the orthopaedic surgeon to understand the risk factors associated with fracture treatments in order to assess the best treatment plan.

Are bilateral tibial shaft fractures associated with an increased risk for adverse outcome?

INTRODUCTION

Long bone fractures are assumed to be an independent risk factor for systemic complications and death after trauma. Multiple studies have identified an increased risk for mortality and morbidity in patients with bilateral femoral fractures. Data about bilateral tibial shaft fractures is rare. The aim of our study was to analyze if patients with bilateral tibial shaft fractures are at higher risk for systemic complications.

METHODS

We performed a retrospective analysis of the TraumaRegister DGU® from 1993 to 2008. Inclusion criteria were unilateral or bilateral tibial shaft fractures and an age ≥16. Additionally to the overall collective we analyzed different subgroups (divided into different injury severities and treatment periods).

RESULTS

1899 patients with unilateral and 175 patients with bilateral tibial shaft fractures were included. Age, gender and mean ISS (25.8 vs. 26.2, p = 0.51) in the two groups were comparable. Regarding the entire study population, patients with bilateral tibial shaft fractures showed no significant higher incidence of respiratory organ failure (29.5% vs. 23.1%, p = 0.076) or mortality (20.0% vs. 16.3%, p = 0.203). However, subgroup analysis showed a significant higher rate of pulmonary organ failure for bilateral tibial shaft fractures as compared to unilateral tibial shaft fractures in the group ISS < 25 (20.7% vs. 11.7%, p = 0.023). Multivariate regression analysis identified the additional tibial shaft fracture as an independent risk factor for pulmonary organ failure (OR = 1.56) but not for mortality.

DISCUSSION

The additional tibial shaft fracture is an independent risk factor for pulmonary organ failure but not for multiple organ failure or mortality. The impact of the additional tibial shaft fracture is especially pronounced in less severely injured patients (ISS < 25). These findings are comparable to results of bilateral femoral fracture studies and we therefore suggest to treat patients with bilateral tibial shaft fractures with the same caution as those with bilateral femoral fractures.

Interlocking screws placed with freehand technique and uni-planar image intensification: the "dip-stick" technique

OBJECTIVE

To report our experience with a novel alternative method of freehand interlocking of intramedullary nails. This method requires the use of only anterior-posterior image intensification and an intramedullary guide wire to verify screw placement. Our results are compared with historical results in the literature.

METHODS

A total of 815 patients were treated using this technique from January 2008 to December 2012; 603 patients had fractures of the tibia and 212 had fractures of the femur.

RESULTS

The mean duration of surgery for tibial shaft fractures was 55.6 minutes (range 42-60 minutes) and that for fractures of the femur was 78 minutes (range 50-90 minutes). The mean time for each distal locking was 3.8 minutes (2.5-5.1 minutes), with 7.65 seconds of exposure to radiation during each block.

CONCLUSIONS

The surgical technique is simple, easy and reproducible. Mean time of surgery and radiation exposure was less than that in the literature. A comparative study should be performed.

The association of reamed intramedullary nailing and long-term cognitive impairment

OBJECTIVES

To examine the association of reamed intramedullary nailing (IMN) and long-term cognitive impairment in trauma intensive care unit survivors.

DESIGN

Prospective observational cohort.

SETTING

Academic Level I trauma center.

PATIENTS

One hundred seventy-three patients with multiple trauma (Injury Severity Score greater than 15) who presented to a Level I trauma intensive care unit from July 2006 to July 2007 without evidence of intrancranial hemorrhage.

INTERVENTION

None.

MAIN OUTCOME MEASURE

Twelve-month cognitive impairment defined a priori as two neuropsychological test scores 1.5 standard deviation below the mean or 1 neuropsychologic test score 2 standard deviations below the mean.

RESULTS

One hundred eight of 173 patients (62.4%) were evaluated 12 months after injury with a comprehensive battery of neuropsychological tests. There were 18 patients who received a reamed IMN and 14 of 18 (78%) of these patients had cognitive deficit at follow-up. Fracture treatment with a reamed IMN was associated with long-term impairment (27.4% vs 8.2%, P = 0.03). Multivariable logistic regression found that a reamed IMN (odds ratio, 3.2; 95% confidence interval, 0.95-10.9; P = 0.06) was a moderate risk factor for the development of cognitive impairment 12 months after injury after controlling for Injury Severity Score, level of education, intraoperative hypotension, and duration of mechanical ventilation.

CONCLUSIONS

Fracture fixation with a reamed IMN is moderately associated with cognitive impairment in this cohort of multiple trauma patients without intrancranial hemorrhage at 1 year postinjury. Orthopaedic trauma research should continue to investigate a potential association of acute fracture management and long-term cognitive outcome.

[Early or delayed peripheral surgery in patients with severe head injury?]

Head injuries are present in up to 65 % of multiple trauma patients with a frequent association with orthopaedic injuries. The concept of early surgical stabilization of long-bone fractures in patients with multiple injuries became firmly established in the 1980s. However, optimal timing of long bone fracture fixation in trauma patients with associated severe traumatic brain injury has been a lively topic. The available literature does not provide clear-cut guidance on the management of fractures in the presence of head injuries. The trend is toward a better outcome if the fractures are fixed early. In recent years, some studies reported a worse outcome, with secondary brain damage, resulting from hypotension, hypoxia and increased intraoperative fluid administration. This review summarises the current evidence available regarding the management of these patients in particular the recent concept of early temporary surgical stabilization in the era of "damage control orthopaedic surgery".

Femur shaft fracture fixation in head-injured patients: when is the right time?

The ideal timing and modality of femur shaft fracture fixation in head-injured patients remains a topic of debate. Several groups advocate the immediate definitive fixation of femur fractures ("early total care"), whereas others support the concept of "damage control orthopaedics" with temporary fracture fixation by means of external fixation and staged, planned conversion to internal fixation. The present review was designed to address this unresolved controversy by outlining the underlying immunopathophysiology of traumatic brain injury and providing clinical recommendations on the timing of femur shaft fracture fixation in patients with severe head injuries.

External skeletal fixation of femoral shaft fractures in polytrauma patients

Introduction. Polytrauma remains a major social, economic and medicine affliction. A successful surgical treatment of polytrauma patients requires an approach predicated on prioritizing injuries. An isolated femur fractures rarely poses any threat but in association with multiple injuries, this fracture assumes greater significance. The proper management of femur fractures in polytrauma can greatly reduce the mortality and morbidity. Material and methods. We present our results in the treatment of 24 femur shaft fracture in 22 polytrauma patients treated by Mitkovic external fixator in 5 year period (2000-2004) on Orthopeadic and Traumatology Clinic - Clinical Center Nis. The average of patients age was 32.8 years (ranging from 17 to 62). There were 11 (46%) closed and 13 (54%) open fractures. Results. Eighteen fractures were treated by external fixation until union. The remaining six fractures were treated by conversion of the external fixation to internal fixation. Sixteen fractures (88.88%), in which the external fixation was the definitive method of treatment, healed completely. The average healing time was 6.29 (4-9) months. There were three pin-track infections (16.66%), one nonunion (5.55%) and only one deep infection (5.55%). Conclusion. The external fixation by the use of Mitkovic external fixator in the treatment of femur fractures is a safe procedure to achieve temporary rigid stabilisation in polytrauma patients before the subsequent internal fixation (damage control orthopaedics). The external fixation using Mitkovic external fixator can be definitive method of choice in treatment of open and comminutiwe femur fractures in polytrauma patients until union.

The effectiveness of the external distal aiming device in intramedullary fixation of tibial shaft fractures

INTRODUCTION

Intramedullary nailing has become a popular and effective procedure for the treatment of most fractures of the tibial diaphysis. However, distal interlocking screw placement under fluoroscopic control is responsible for the majority of the radiation exposure and a significant loss of surgical time in the entire nailing procedure. To limit fluoroscopy use, during distal interlocking screw placement, Orthofix has developed a distal targeting device which compensates for the inevitable deformation of the nail in the sagittal plane during its insertion. This prospective clinical study evaluates the efficacy of this distal targeting device for distal locking.

MATERIALS AND METHODS

One hundred and fifteen fresh tibial fractures in the same number of patients with a mean age of 37.5 years (17-85 years) were treated with operative stabilization using the Orthofix tibial nailing system.

RESULTS

The mean duration of the operation was 38 min (20-55 min). A mean of four intra-operative plain X-rays (2-6 X-rays) were used in 103 cases to confirm guide wire placement, final nail insertion and accuracy of screws placement. The mean duration of the use of the image intensifier utilized in the remaining 12 fractures was 5 s (3-8 s). The distal targeting device failed in 12 (5.2%) distal locking screws.

CONCLUSION

This study demonstrates that distal locking can be performed easily and successfully with minimal exposure to radiation, once the surgeon develops a reasonable experience with the use of this distal targeting device.

Eight years' clinical experience with the Orthofix tibial nailing system in the treatment of tibial shaft fractures

Intramedullary nailing has become a popular and effective procedure for the treatment of most tibial fractures. However, concerns regarding difficulties with reduction, the use and extent of intramedullary reaming, and hardware failure are probably the only constraints to its widespread use. In this prospective study, we present the clinical and radiographic results of the Orthofix tibial nailing system used in the treatment of tibial shaft fractures. One hundred and fifteen fresh tibial fractures in the same number of patients with a mean age of 37.5 years (17-85 years) were treated with operative stabilisation using the Orthofix tibial nailing system. All of the operations took place in a conventional operating theatre, on a simple tranlucent operating table and with manual reduction of the fracture. In the majority of the cases closed reduction and conventional reaming were performed and the mean duration of the operation was 38 min. Fracture healing occurred at 16 weeks (11-30 weeks) and was confirmed both clinically and radiographically. In six cases (two severely comminuted and four segmental fractures) delayed union occurred, however there were no tibial non-unions necessitating re-operation. There were no substantial differences in time to fracture union or in the rate of complications related to minimal open reduction. In addition, there seem to be more benefits than risks in the use of power intramedullary reaming during intramedullary fixation of tibial shaft fractures. In conclusion, most tibial shaft fractures can effectively and safely be treated using this type of locking intramedullary nailing device, with relatively few complications, and with satisfactory long-term clinical results.

Prevention of fat embolism syndrome

Fat embolism syndrome is a condition of acute respiratory distress following long-bone trauma. This condition may involve not only the lungs but also a number of other body systems. The pathophysiology is not as yet clearly understood, however, intravasation of fat from long-bone fractures may play a role. Early recognition of the severity of injury both on clinical and biochemical grounds and early surgical stabilization of long bones may help to decrease its incidence. However, the best surgical technique with which to do this stabilization has not yet been clearly determined. Surgical and pharmacological techniques have been developed in an attempt to either decrease the intravasation of fat during long-bone stabilization or block the inflammatory cascade with varying degrees of efficacy. Ongoing research focuses on both the prevention and treatment of this condition.

[Traumatic brain injury: impact on timing and modality of fracture care]

Traumatic brain injury (TBI) represents the major "killing factor" after trauma in young individuals. Those patients who survive the initial injury are highly susceptible to secondary insults to the injured brain which are mainly caused by hypotension and/or hypoxia in the early resuscitative period. Furthermore, a potent inflammatory cascade is initiated within the injured brain which leads to the development of brain edema and delayed neuronal cell death. This profound endogenous neuroinflammatory response after TBI, which is phylogenetically aimed at repairing lesioned tissue and defending the brain from invading pathogens, is in large part responsible for the extent of secondary brain damage and adverse outcome. Thus, the optimal management of the multiply injured patient, based on a thorough understanding of the pathophysiological alterations after TBI, should avoid an iatrogenic "second hit" which may be devastating to the injured brain. The standard approach of "early total care" for isolated fractures should be strictly avoided in brain-injured patients in favor of an "orthopedic damage control" concept with temporary external fixation of long bone fractures and priority given to early transfer to intensive care. The present review provides an up-to-date overview on the neuroinflammatory pathophysiology of brain injury and its implications for an optimized concept of fracture care in TBI patients.

Fatal traffic injuries among pedestrians, bicyclists and motor vehicle occupants

The objective of this study was to investigate characteristic injuries of pedestrians and bicyclists (unprotected) compared to motor vehicle occupants' (protected) in fatal traffic accidents. Cases of 664 fatal traffic accidents (371 pedestrians, 45 bicyclists, and 248 motor vehicle occupants) were collected from 1999 to 2001 using the database of the Forensic Institute in Budapest. Autopsy reports were analyzed. Location of injuries, blood alcohol levels, seasonal distribution and natural diseases influencing accident outcome were evaluated. For statistical analysis, odds ratio (OR) with 95% confidence interval (CI) was used by a conditional logistic regression. There were substantial differences in distribution of injuries suffered by pedestrians, bicyclists and motor vehicle occupants. Among pedestrians and bicyclists there was a higher rate of head injuries, such as skull fractures, epidural haemorrhage, subdural haemorrhage, brain contusion, and injuries of the lower extremities. Thoracic damages, such as traumatic aortic rupture, hemothorax, and abdominal damages, like liver rupture were dominant in motor vehicle occupants. Considering existing natural diseases, coronary artery disease was the only one with higher occurrence among motor vehicle occupants 24 (9.7%) compared with pedestrians and bicyclist 36 (8.6%). These results underline the importance of preventive strategies in transportation, pointing out that different methods are necessary to reduce fatal injuries of various traffic participants.

Réunion de neuroanesthésie-réanimation. Prise en charge anesthésique du patient en hypertension intracrânienne aiguë

Transcranial Doppler and, if possible, measurement of intracranial pressure (ICP) allow preoperative diagnosis of acute intracranial hypertension (ICH) after brain trauma. The main goal of the anaesthesiologist is to prevent the occurrence of secondary brain injuries and to avoid cerebral ischaemia. Treatment of high ICP is mainly achieved with osmotherapy. High-dose mannitol administration (1.4 to 2 g/kg given in bolus doses) may be considered a better option than conventional doses, especially before emergency evacuation of a cerebral mass lesion. Hypertonic saline seems as effective as mannitol without rebound effect and without diuresis increase. Haemostasis should be normalized before neurosurgery and invasive blood pressure monitoring is mandatory. For anaesthesia induction, thiopental or etomidate may be used. In case of ICH, halogenated and nitrous oxide should be avoided. Until the dura is open, mean arterial pressure should be maintained around 90 mmHg (or cerebral perfusion pressure around 70 mmHg). If a long-lasting (several hours) extracranial surgery is necessary, ICP should be monitored and treatment of ICH should have been instituted before.

Complications encountered while using thin-wire-hybrid-external fixation modular frames for fracture fixation. A retrospective clinical analysis and possible support for "Damage Control Orthopaedic Surgery"

One hundred ninety eight adult patients who had sustained long bone fractures were treated by external fixation from admission to bone healing and consolidation. Of these, 135 had sustained high-energy injuries, 39 of them had suffered multi-system injuries. Superficial pin track infection was the most common complication, occurring predominantly in pins located in the femur, upper tibia and upper humerus. There were no cases of deep infection or osteomyelitis. One patient with a femoral shaft fracture developed a DVT although he was on preventive low molecular weight heparin, i.e. sc Clexane 40 mg daily. There were no cases of PE or ARDS. External fixation systems are a minimal invasive surgical modality, which allow three-dimensional fracture fixation after closed or minimal open reduction. They require a good command of surgical anatomy, but provide an optimal preservation of the fracture's soft tissue envelope, the critical biological factor for new bone formation and fracture healing. Recent publications have suggested that in the critically ill patient, minimally invasive fracture fixation surgery may prevent the perpetuation of a reactive, life threatening inflammatory reaction (the "second hit") which may induce the development of multiple organ dysfunction (MODS).

[Decision making and and priorities for surgical treatment during and after shock trauma room treatment]

OBJECTIVE

Concepts for optimal surgical treatment of the patient with blunt multiple injuries are being evaluated on the basis of the current literature.

METHODS

Clinical trials were systematically collected (Medline, Cochrane and hand searches) and classified into evidence levels (1 to 5 according to the Oxford system).

RESULTS

The posttraumatic clinical course is divided into four different periods: acute-, primary-, secondary- und tertiary period. The first and second period are important for life saving surgery and the stabilization of major fractures. After the cardiorespiratory systems have been stabilized, the following priorities have been formulated: head, face, spine, abdomen, extremities. To restrict the degree of operative burden on the patient it appears to be necessary to limit the duration of initial surgery to less than 6 hours. In patients at high risk to develop posttraumatic complications-"borderline patients"-it appears safer to perform only temporary fixation of major fractures.

CONCLUSIONS

Three different factors determine the clinical course after polytrauma: Trauma represents the first hit, followed by the therapy-induced burden (second hit). In addition, the third hit is represented by the individual response. An evaluation of the clinical status by immunologic monitoring can be performed in order to assess the patient's status.

Embolia gordurosa: uma revisão para a prática ortopédica atual

A embolia gordurosa (EG) é a oclusão de pequenos vasos por gotículas de gordura, geralmente originadas nas fraturas do fêmur, tíbia e bacia, e nas artroplastias do joelho e quadril. Normalmente não causa danos aos órgãos atingidos, a menos que seja maciça. Em poucos casos a EG evolui para a "síndrome da embolia gordurosa" (SEG) a qual afeta principalmente os pulmões e o cérebro, embora qualquer órgão ou estrutura do organismo possa ser afetada. A gordura embolizada é hidrolizada pela lipase, originando os ácidos graxos livres (AGL) que agem toxicamente sobre o endotélio capilar e que intensificam a ação das integrinas as quais acentuam a adesividade dos neutrófilos às células endoteliais, facilitando a ação das enzimas proteolíticas dos lisossomas desses neutrófilos sobre o endótelio. O resultado dessas reações é a ruptura da rede capilar seguida de hemorragia e edema nos órgãos afetados. A SEG apresenta desde insuficiência respiratória e alterações neurológicas variadas até convulsões e coma profundo. O diagnóstico da SEG é puramente clínico, não existindo nenhum exame laboratorial que o confirme. Dentre os exames de imagens, apenas a ressonância magnética cerebral demonstra claramente as áreas do edema perivascular e dos infartos. O tratamento da EG com inúmeras drogas não apresentou resultados positivos; no entanto, a medida mais requisitada para a SEG é a assistência ventilatória. A mortalidade é quase de 100% nas formas fulminantes; aproximadamente de 20% nas formas sub-agudas e não há mortalidade na forma sub-clínica. Para prevenir a SEG é fundamental evitar o choque e a hipóxia desde a cena do acidente, e proceder à fixação precoce das fraturas, o que diminui a incidência de SARA e a mortalidade pós-trauma.

Traumatic brain injury and stabilisation of long bone fractures: an update

In the era of "damage control orthopaedics", the timing and type of stabilisation of long bone fractures in patients with associated severe traumatic brain injury has been a topic of lively debate. This review summarises the current evidence available regarding the management of these patients. There appear to be no clear treatment guidelines. Irrespective of the treatment protocol followed, if secondary brain damage is to be avoided at all times, ICP monitoring should be used, both in the intensive care unit and in the operating theatre during surgical procedures, since aggressive ICP management appears to be related to improved outcomes. Treatment protocols should be based on the individual clinical assessment, rather than mandatory time policies for fixation of long bone fractures.

Damage control: extremities

The principles of fracture management in polytrauma patients continue to be of crucial importance. Over the last five decades, various strategies of fracture treatment in the multiply injured patient have evolved. The various new methodologies remain controversial. In the beginning, early surgical fracture treatment of long bone fractures after multiple trauma was not routinely advocated. It was believed that the polytraumatised patient did not have the physiological reserve to withstand prolonged operations. The introduction of standardised, definitive surgical protocols, led to the concept of early total care (ETC) in the 1980s. This concept was subsequently applied universally, in all patient groups, regardless of injury severity and distribution. Later, it became apparent that certain patients did not appear to benefit from ETC. Indeed, extended operative procedures, during the early phase of multiple trauma recovery, were associated with adverse outcome. This applied for patients with significant thoracic, abdominal and head injuries and those with high injury severity scores (ISS). In response, the concept of damage control orthopaedics (DCO) was developed in the 1990s. DCO methodology is characterised by primary, rapid, temporary fracture stabilization. Secondary definitive management follows, once the acute phase of systemic recovery has passed. We explore the processes underlying the systemic biological impact of fracture fixation, the evolution of operative treatment strategies for major fractures in polytrauma and the current trends toward staged management of these patients.
