Abstract
INTRODUCTION The optimal timing to definitive osteosynthesis in the polytraumatized patient remains an unanswered question. Early total care, damage control orthopaedics, and early appropriate care have been described to manage the fractures in these patients, but there is a paucity of literature specific to ipsilateral tibial and femoral fractures. We sought the perioperative outcomes of primary simultaneous intramedullary nailing (IMN) versus temporizing external fixation (EF) of both fractures. METHODS A chart review of all patients who sustained fractures of the ipsilateral femur and tibia that were definitively treated with (IMN) from January 2010 to December 2020 was performed. Patients who underwent initial EF and those that were primarily treated with IMNs were examined. RESULTS IMNs and EF were the initial treatment in 23 and 16 patients, respectively. The mean (range) injury severity score (ISS) was 23.3 (33) in the EF group vs. 18.5 (34) in the IMN group, (p = 0.0686). The EF group had a higher total transfused units of packed red blood cells 7.4 vs. 2.8, the mean initial operative time was 236 vs. 282.6 (min), (p = 0.7399), a longer mean total operative time 601.78 vs. 236 (min), and longer mean length of stay 15.6 vs. 11 (days), (p < 0.5). Rates of complications were not significantly different between groups. CONCLUSION Primary IMN is as safe as provisional EF in the adequately resuscitated patient with ipsilateral femoral and tibial fractures. This implies the fixation of both fractures into a single surgery without increasing perioperative complications, and decreasing total hospital stay in patients with sufficient preoperative resuscitation.

Abstract
In Orthopedics, damage control is indicated in patients with pelvic and/or long bone fractures associated with hemodynamic instability. It is inappropriate to perform a complex definitive reduction and fixation surgery for severely injured trauma patients with hemodynamic instability. In these cases, it is recommended to perform minimally invasive procedures that temporarily stabilize the fractures and bleeding control. Closed or open fractures of the long bones such as femur, tibia, humerus, and pelvis can lead to hemodynamic instability and shock. Thus, orthopedic damage control becomes a priority. However, if the patient is hemodynamically stable, it is recommended to stabilize all fractures with an early permanent internal fixation. These patients will have a shorter hospital length of stay and a reduction in mechanical ventilation, blood components transfusions and complications. Therefore, the concept of orthopedic damage control should be individualized according to the hemodynamic status and the severity of the injuries. Open fractures, dislocations, and vascular injuries could lead to permanent sequelae and complications if a correct management and approach are not performed.

Abstract
Purpose Treatment strategies for femoral fracture stabilisation are well known to have a significant impact on the patient’s outcome. Therefore, the optimal choices for both the type of initial fracture stabilisation (external fixation/EF, early total care/ETC, conservative treatment/TC) and the best time point for conversion from temporary to definitive fixation are challenging factors. Patients Patients aged ≥ 16 years with moderate and severe trauma documented in the TraumaRegister DGU® between 2002 and 2018 were retrospectively analysed. Demographics, ISS, surgical treatment strategy (ETC vs. EF vs. TC), time for conversion to definitive care, complication (MOF, sepsis) and survival rates were analysed. Results In total, 13,091 trauma patients were included. EF patients more often sustained high-energy trauma (car: 43.1 vs. 29.5%, p < 0.001), were younger (40.6 vs. 48.1 years, p < 0.001), were more severely injured (ISS 25.4 vs. 19.1 pts., p < 0.001), and had higher sepsis (11.8 vs. 5.4%, p < 0.001) and MOF rates (33.1 vs. 16.0%, p < 0.001) compared to ETC patients. A shift from ETC to EF was observed. The time until conversion decreased for femoral fractures from 9 to 8 days within the observation period. Sepsis incidences decreased in EF (20.3 to 12.3%, p < 0.001) and ETC (9.1–4.8%, p < 0.001) patients. Conclusions Our results show the changes in the surgical treatment of severely injured patients with femur fractures over a period of almost two decades caused by the introduction of modern surgical strategies (e.g., Safe Definitive Surgery). It remains unclear which subgroups of trauma patients benefit most from these strategies.

Abstract
Trauma remains a leading global cause of mortality, particularly in the young population. In the United States, approximately 30,000 patients with blunt cardiac trauma were recorded annually. Cardiac damage is a predictor for poor outcome after multiple trauma, with a poor prognosis and prolonged in-hospitalization. Systemic elevation of cardiac troponins was correlated with survival, injury severity score, and catecholamine consumption of patients after multiple trauma. The clinical features of the so-called "commotio cordis" are dysrhythmias, including ventricular fibrillation and sudden cardiac arrest as well as wall motion disorders. In trauma patients with inappropriate hypotension and inadequate response to fluid resuscitation, cardiac injury should be considered. Therefore, a combination of echocardiography (ECG) measurements, echocardiography, and systemic appearance of cardiomyocyte damage markers such as troponin appears to be an appropriate diagnostic approach to detect cardiac dysfunction after trauma. However, the mechanisms of post-traumatic cardiac dysfunction are still actively being investigated. This review aims to discuss cardiac damage following trauma, focusing on mechanisms of post-traumatic cardiac dysfunction associated with inflammation and complement activation. Herein, a causal relationship of cardiac dysfunction to traumatic brain injury, blunt chest trauma, multiple trauma, burn injury, psychosocial stress, fracture, and hemorrhagic shock are illustrated and therapeutic options are discussed.

Abstract
The principles of fracture management in patients with multiple injuries continue to be of crucial importance. Early treatment of unstable polytraumatized patients with head, chest, abdomen or pelvic injuries, with blood loss followed by immediate fracture fixation (Early Total Care -ETC) may be associated with secondary life threatening posttraumatic systemic inflammatory response syndrome (SIRS). Development of SIRS is typically a function of the type and severity of the initial injury (the "first hit"). Immediate Fracture fixation, using reamed nails or plates, in such unstable patients with multiple injuries is subsequently defined as the "second hit" and may be associated with development of acute respiratory distress syndrome (ARDS) and multiple organ failure (MOF), with relatively high morbidity and mortality. The other alternative for long bone fracture fixation in unstable polytraumatized patients is based on immediate treatment of life threatening conditions related to the injuries, followed by the initial use of minimally invasive modular external frames for long bone fractures and is called Damage Control Orthopedics (DCO) and is widely accepted. In order to refine the DCO concept and to avoid an overuse of external fixation, the "Safe Definitive Surgery" (SDS) concept has been introduced, which is a dynamic synthesis of both strategies (ETC and DCO). The SDS strategy employs clinical parameters and includes repeated assessment of patients. The following paper is going to summarize historical backgrounds and recent concepts in treatment of polytraumatized patients.

Abstract
Injury-related morbidity and mortality have been one of the most common causes of loss in productivity across all geographic distributions. It remains to be a global concern despite a continual improvement in regional and national safety policies. The establishment of trauma care systems and advancements in diagnostics and management have improved the overall survival of severely injured. A better understanding of the physiopathological and immunological responses to injury led to a significant shift in trauma care from "Early Total Care" to "Damage Control Orthopedics." While most of these algorithms were tailored to the philosophy of "life before limb," the impact of improper fracture management on disability and societal loss is increasingly being recognized. Recently, "Early Appropriate Care" of extremities has gained importance; however, its implementation is influenced by regional health care policies, available resources, and expertise and varies between low and high-income countries. A review of the literature was performed using PubMed, Embase, Web of Science, and Scopus databases on articles published from 1990 to 2020 using the Mesh terms "Polytrauma," "Multiple Trauma," and "Fractures." This review aims to consolidate on guidelines and available evidence in the management of extremity injuries in a polytraumatized patient to achieve better clinical outcomes of these severely injured.

Abstract
Cardiac injuries are recorded after multiple trauma and are associated with a poor patient outcome. Reaming prior to locked intramedullary nailing is a frequently used technique to stabilize femoral diaphysis fractures. However, in polytraumatized patients, complications such as fat emboli and acute respiratory distress syndrome have been associated with reaming. The reaming irrigator aspirator (RIA) system provides concomitant irrigation and suction of the intramedullary contents, and should, therefore, reduce reaming-associated complications. The aim of the study was to investigate cardiac function after multiple trauma with regard to two different RIA devices (RIAI vs RIAII). 15 male pigs were included in the study. Pigs received either sham treatment or multiple trauma (chest trauma, femur fracture, liver laceration, and hemorrhagic shock), followed by intramedullary nailing after reaming with either the RIAI or RIAII system (RIAII: reduced diameter of the reamer, improved control of irrigation and suction). Cardiac function was assessed by transesophageal echocardiography and systemic inflammation as well as local cardiac damage examined. Pigs of both treatment groups showed impaired cardiac function, valvular insufficiency, and cardiac damage. Systemic inflammation and local cardiac alterations were observed which might contribute to early myocardial damage in vivo. Multiple trauma including long-bone fracture and subsequent intramedullary reaming induces cardiac dysfunction and valvular insufficiency, which might be linked to both mechanical cardiac injury and increased systemic inflammation. 6 hours after trauma there are less differences between RIAI and RIAII treatment with regard to post-traumatic cardiac consequences in multiple injured pigs, indicating no beneficial effect of RIAII over RIAI.

Abstract
Reamed intramedullary nailing (RIN) is a surgical method of choice for treatment of diaphyseal fractures. This procedure affects the biological environment of bone tissue locally and systemically. This study investigated the influence of RIN on mesenchymal stem cells (MSCs) in patients with long bone fractures. The axis of C-X-C motif chemokine receptor 4 (CXCR4)/stromal cell-derived factor 1 (SDF-1) was selected since it is considered as major pathway for MSC homing and migration. Iliac crest bone marrow (IC-BM) samples and blood samples were collected at two different time points. One sample was collected before the RIN (BN) and the other immediately after RIN (AN). BM-MSCs were cultured and RT-qPCR was performed for CXCR4 mRNA levels and ELISA for the SDF-1 sera levels. The experimental study revealed that there was a correlation between the increase of SDF-1 levels in peripheral blood and a decrease in the levels of CXCR4 in MSCs in the IC-BM following RIN. The levels of SDF-1 showed a significant increase in the sera of patients after RIN. In conclusion, the present study is the first providing evidence of the effects of RIN on MSC population via the CXCR4/SDF-1 axis. The levels of serum SDF-1 factor were elevated after RIN while increased levels of SDF-1 in peripheral blood were inversely correlated with the mRNA levels of CXCR4 on BM-MSCs after RIN. Therefore, this study contributes to enlighten the systematic effects of RIN on the population of MSCs at a cellular level.

Structural alterations and inflammation in the heart after multiple trauma followed by reamed versus non-reamed femoral nailing. PLoS One 2020; 15:e0235220.

Abstract
BACKGROUND Approximately 30,000 patients with blunt cardiac trauma are recorded each year in the United States. Blunt cardiac injuries after trauma are associated with a longer hospital stay and a poor overall outcome. Organ damage after trauma is linked to increased systemic release of pro-inflammatory cytokines and damage-associated molecular patterns. However, the interplay between polytrauma and local cardiac injury is unclear. Additionally, the impact of surgical intervention on this process is currently unknown. This study aimed to determine local cardiac immunological and structural alterations after multiple trauma. Furthermore, the impact of the chosen fracture stabilization strategy (reamed versus non-reamed femoral nailing) on cardiac alterations was studied. EXPERIMENTAL APPROACH 15 male pigs were either exposed to multiple trauma (blunt chest trauma, laparotomy, liver laceration, femur fracture and haemorrhagic shock) or sham conditions. Blood samples as well as cardiac tissue were analysed 4 h and 6 h after trauma. Additionally, murine HL-1 cells were exposed to a defined polytrauma-cocktail, mimicking the pro-inflammatory conditions after multiple trauma in vitro. RESULTS After multiple trauma, cardiac structural changes were observed in the left ventricle. More specifically, alterations in the alpha-actinin and desmin protein expression were found. Cardiac structural alterations were accompanied by enhanced local nitrosative stress, increased local inflammation and elevated systemic levels of the high-mobility group box 1 protein. Furthermore, cardiac alterations were observed predominantly in pigs that were treated by non-reamed intramedullary reaming. The polytrauma-cocktail impaired the viability of HL-1 cells in vitro, which was accompanied by a release of troponin I and HFABP. DISCUSSION Multiple trauma induced cardiac structural alterations in vivo, which might contribute to the development of early myocardial damage (EMD). This study also revealed that reamed femoral nailing (reamed) is associated with more prominent immunological cardiac alterations compared to nailing without reaming (non-reamed). This suggests that the choice of the initial fracture treatment strategy might be crucial for the overall outcome as well as for any post-traumatic cardiac consequences.

Abstract
Background: The complement system is part of the innate immunity, is activated immediately after trauma and is associated with adult respiratory distress syndrome, acute lung injury, multiple organ failure, and with death of multiply injured patients. The aim of the study was to investigate the complement activation in multiply injured pigs as well as its effects on the heart in vivo and in vitro. Moreover, the impact of reamed vs. non-reamed intramedullary nailing was examined with regard to the complement activation after multiple trauma in pigs. Materials and Methods: Male pigs received multiple trauma, followed by femoral nailing with/without prior conventional reaming. Systemic complement hemolytic activity (CH-50 and AH-50) as well as the local cardiac expression of C3a receptor, C5a receptors1/2, and the deposition of the fragments C3b/iC3b/C3c was determined in vivo after trauma. Human cardiomyocytes were exposed to C3a or C5a and analyzed regarding calcium signaling and mitochondrial respiration. Results: Systemic complement activation increased within 6 h after trauma and was mediated via the classical and the alternative pathway. Furthermore, complement activation correlated with invasiveness of fracture treatment. The expression of receptors for complement activation were altered locally in vivo in left ventricles. C3a and C5a acted detrimentally on human cardiomyocytes by affecting their functionality and their mitochondrial respiration in vitro. Conclusion: After multiple trauma, an early activation of the complement system is triggered, affecting the heart in vivo as well as in vitro, leading to complement-induced cardiac dysfunction. The intensity of complement activation after multiple trauma might correlate with the invasiveness of fracture treatment. Reaming of the femoral canal might contribute to an enhanced “second hit” response after trauma. Consequently, the choice of fracture treatment might imply the clinical outcome of the critically injured patients and might be therefore crucial for their survival.

Abstract
Femoral shaft fractures after completion of growth predominantly affect young people with healthy bones. The causes are mostly high-velocity traffic accidents, crushing or running over mechanisms and falls from a great height. Gunshot wounds are relatively rare in Germany but have a certain importance internationally and in military medicine. Accompanying injuries in local or other regions are frequent. The predominant fracture types are transverse, wedge, segment and comminuted fractures. Spiral fractures are a sign of indirect force and are therefore frequently found in older patients with osteoporosis. Atypical fractures under or following bisphosphonate treatment are a new entity, which are typically subtrochanteric and begin on the lateral side of the bone. The characteristics of pathological fractures, femoral shaft fractures in childhood and adolescence as well as periprosthetic fractures are not dealt with in this article.

Incidence and risk factors for complications after definitive skeletal fixation of lower extremity in multiple injury patients: a retrospective chart review. F1000Res 2018; 7:612.

Abstract
Background: The management of multiple injuries is complex. Type and timing of treatment for lower extremity fractures is a controversial subject. Although many studies have demonstrated the safety and effectiveness of early treatment, others have suggested that early definitive stabilization may cause complications, especially with chest and head injuries. The aim of this study was to determine the complications and effects of timing of fixation, and investigate risk factors for complications in multiple injuries patients with lower extremity fractures. Methods: A Retrospective chart review from Khon Kaen Trauma Registry between 2008 and 2015 were collected. All major complications were identified and collected for example acute respiratory distress syndrome (ARDS), acute kidney injury (AKI) and sepsis. The time to definitive skeletal fixation from initial injury was identified and analyzed with multiple logistic regression. Results: 1224 multiple injuries patients with lower extremity fractures were identified. The mean age was 34±19.5 years, 74.4% were male and 25.6% female. The mean time from initial injury to definitive operation was 55.7±53.9 hours. Complications occurred with 178 patients (14.5%), the most common of which were pneumonia, ARDS and AKI. After adjusting for sex, severity of injury, we found that the operation within 24-48 hours complication was 6.67 times less common than in the early treatment group (less than 24 hours) (95% CI: 3.03 to 10.00, P-value< 0.001). Conclusions: About 15% of the multiple injuries patients with lower extremity fracture had major complications. The optimal time for definitive fixation in lower extremity fractures to reduce complications was within 24-48 hours. We found that if we operated too early (before 24 hours) or more than 48 hours after the injury it could increase the morbidity and mortality.

Abstract
Bone healing, biocompatibility, and safety employing the IlluminOss System (IS), comprised of an inflatable balloon filled with photopolymerizable liquid monomer, was evaluated in New Zealand white rabbits. Successful bone healing and callus remodeling over 6 months was demonstrated radiologically and histologically with IS implants in fenestrated femoral cortices. Biocompatibility was demonstrated with IS implants in brushed, flushed femoral intramedullary spaces, eliciting no adverse, local, or systemic responses and with similar biocompatibility to K-wires in contralateral femurs up to 1 year post-implant. Lastly simulated clinical failures demonstrated the safety of IS implants up to 1 year in the presence of liquid or polymerized polymer within the intramedullary space. Polymerized material displayed cortical bone and vasculature effects comparable to mechanical disruption of the endosteum. In the clinically unlikely scenario with no remediation or polymerization, a high dose monomer injection resulted in marked necrosis of cortical bone, as well as associated vasculature, endosteum, and bone marrow. Overall, when polymerized and hardened within bone intramedullary spaces, this light curable monomer system may provide a safe and effective method for fracture stabilization. © 2017 Orthopaedic Research Society.

Abstract
The objective of this systematic review and meta-analysis was to compare the lengthening and then nailing (LATN) technique to the conventional Ilizarov method for limb lengthening. A systemic search of potential relevant literature was performed in databases, including the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, EMBASE, and the ISI Web of Knowledge, from their inception to 22 May 2015 using medical subject heading (MeSH) terms "Ilizarov," "bone lengthening," or "intramedullary nail." A total of 89 titles and abstracts were preliminarily reviewed, of which 4 studies eventually satisfied the eligibility criteria, consisting of one randomized controlled trial (RCT), two clinical controlled trials and one retrospective cohort study. A total of 354 limbs were included in the study, among which 183 were lengthened over an intramedullary nail, and 171 limbs were lengthened conventionally. The mean difference (MD) was -50.21 for the external fixation index between the two groups (95% CI, -51.83 to -48.59; P < 0.00001) with high heterogeneity (I2 = 99%); no significant difference in length was gained (MD = -0.30, 95% CI = -0.72 to 0.12; P = 0.16) with high heterogeneity (I2 = 80%); and there was high significant difference for the consolidation index (MD = -19.97; 95% CI, -21.59 to -18.35; P < 0.00001) with high heterogeneity (I2 = 100%). The overall rate of complications was relatively low, and differed significantly between the two groups. Through this meta-analysis, we find that LATN is superior to the conventional method in regards to the external fixation index and the consolidation index, which means that LATN is an effective technique that can decrease the time needed in external fixation.

Abstract
Intramedullary nailing, as the gold standard stabilisation method of most long bones, has been tailed by its extensive use as the basic tool of investigating the immune response to trauma in many large and small animal models, as well as at the clinical setting. Over the last few decades a complex map of interactions between pro and anti-inflammatory pathways has been the result of these significant global research efforts. Parallel to the evolution of modern nailing and reaming techniques, significant developments at the fields of other disciplines relevant to trauma care, has improved the contemporary management of injured patients, challenging previous concepts and altering clinical barriers. The current article aims to summarise the current understanding of the effect of instrumenting the medullary canal after trauma, and hint on potential future directions.

Abstract
Although its original clinical description dates from the nineteenth century, fat embolism syndrome remains a diagnostic challenge for clinicians. Fat emboli occur in all patients with long-bone fractures, but only few of them develop a multisystem disorder affecting the lung, brain, and skin, also known as fat embolism syndrome (FES). The incidence of FES varies and is often underestimated. Mechanical and biochemical theories have been proposed for the pathophysiology of FES. Clinical manifestations consist of respiratory and cerebral dysfunction and a petechial rash. Diagnosis of FES is difficult and based mainly on clinical criteria. FES is a self-limiting disease and treatment needs to be mainly supportive. Surgical treatment of the coexistent injuries is still obscured by controversies and the treatment methods used provide inconclusive results. In this context, prevention focuses on the early identification of predisposing factors.

Abstract
BACKGROUND Previous work established resuscitation parameters that minimize complications with early fracture management. This Early Appropriate Care (EAC) protocol was applied to patients with advanced age to determine if they require unique parameters to mitigate complications. METHODS Between October 2010 and March 2013, 376 consecutive skeletally mature patients with unstable fractures of the pelvis, acetabulum, thoracolumbar spine, and/or proximal or diaphyseal femur fractures were treated at a level I trauma center and were prospectively studied. Patients aged ≤30 years (n = 114), 30 to 60 years (n = 184), and ≥60 years (n = 37) with Injury Severity Scores (ISS) ≥16 and unstable fractures of the pelvis, acetabulum, spine, and/or diaphyseal femur were treated within 36 h, provided they showed evidence of adequate resuscitation. ISS, Glasgow Coma Scale (GCS), and American Society of Anesthesiologists (ASA) classification were determined. Lactate, pH, and base excess (BE) were measured at 8-h intervals. Complications included pneumonia, pulmonary embolism (PE), acute renal failure, acute respiratory distress syndrome (ARDS), multiple organ failure (MOF), deep vein thrombosis, infection, sepsis, and death. RESULTS Patients ≤30 years old (y/o) were more likely to sustain gunshot wounds (p = 0.039), while those ≥60 y/o were more likely to fall from a height (p = 0.002). Complications occurred at similar rates for patients ≤30 y/o, 30 to 60 y/o, and ≥60 y/o. There were no differences in lactate, pH, or BE at the time of surgery. For patients ≤30 y/o, there were increased overall complications if pH was <7.30 (p = 0.042) or BE <-6.0 (p = 0.049); patients ≥60 y/o demonstrated more sepsis if BE was <-6.0 (p = 0.046). CONCLUSIONS EAC aims to definitively manage axial and femoral shaft fractures once patients have been adequately resuscitated to minimize complications. EAC is associated with comparable complication rates in young and elderly patients. Further study is warranted with a larger sample to further validate EAC in elderly patients.

Abstract
Severe tissue trauma leads to an early activation of several danger recognition systems, including the complement and the coagulation system, often resulting in an overwhelming almost synchronic pro- and anti-inflammatory response of the host. Although the immune response is associated with beneficial effects at the site of injury including the elimination of exogenous and endogenous danger molecules as well as the initiation of regenerative processes, an exaggerated systemic inflammatory response significantly contributes to posttraumatic complications such as multiple organ failure (MOF) and early death. Besides pre-existing physical conditions, age, gender, and underlying comorbidities, surgical and anesthesiological management after injury is decisive for outcome. Improvements in surgical intensive care have increased number of patients who survive the initial phase after trauma. However, instead of progressing to normal recovery, patients often pass into persistent inflammation, immunosuppression, and catabolism syndrome (PICS). The characterization and management of PICS will require new strategies for direct monitoring and therapeutic intervention into the patient’s immune function. In this chapter, we describe various factors involved in the inflammatory changes after trauma and aim to understand how these factors interact to progress to systemic inflammation, MOF, and PICS.

Abstract
Background Optimal patterns for fluid management are controversial in the resuscitation of major trauma. Similarly, appropriate surgical timing is often unclear in orthopedic polytrauma. Early appropriate care (EAC) has recently been introduced as an objective model to determine readiness for surgery based on the resuscitation of metabolic acidosis. EAC is an objective treatment algorithm that recommends fracture fixation within 36 h when either lactate <4.0 mmol/L, pH ≥ 7.25, or base excess (BE) ≥−5.5 mmol/L. The aim of this study is to better characterize the relationship between post-operative complications and the time required for resuscitation of metabolic acidosis using EAC. Methods At an adult level 1 trauma center, 332 patients with major trauma (Injury Severity Score (ISS) ≥16) were prospectively treated with EAC. The time from injury to EAC resuscitation was determined in all patients. Age, race, gender, ISS, American Society of Anesthesiologists score (ASA), body mass index (BMI), outside hospital transfer status, number of fractures, and the specific fractures were also reviewed. Complications in the 6-month post-operative period were adjudicated by an independent multidisciplinary committee of trauma physicians and included infection, sepsis, pulmonary embolism, deep venous thrombosis, renal failure, multiorgan failure, pneumonia, and acute respiratory distress syndrome. Univariate analysis and binomial logistic regression analysis were used to compare complications between groups. Results Sixty-six patients developed complications, which was less than a historical cohort of 1,441 patients (19.9 % vs. 22.1 %). ISS (p < 0.0005) and time to EAC resuscitation (p = 0.041) were independent predictors of complication rate. A 2.7-h increase in time to resuscitation had odds for sustaining a complication equivalent to a 1-unit increase on the ISS. Conclusions EAC guidelines were safe, effective, and practically implemented in a level 1 trauma center. During the resuscitation course, increased exposure to acidosis was associated with a higher complication rate. Identifying the innate differences in the response, regulation, and resolution of acidosis in these critically injured patients is an important area for trauma research. Level of evidence Level 1: prognostic study.

Abstract
Purpose : Appropriate timing of definitive fracture care in the setting of polytrauma remains controversial. The aim of this study is to determine whether timing of definitive fixation of femur fractures impacts subsequent length of hospital stay, a surrogate for postoperative morbidity, in patients with multi-system trauma. Methods : Secondary analysis of data from the National Trauma Data Bank (January 1, 2000 to December 31, 2004) was performed. Adult patients who: (1) had an open or closed femoral shaft fracture, (2) had an injury severity score (ISS) greater than or equal to 15, (3) and underwent definitive internal fixation were included. Time to fixation was divided into 5 time periods based on commonly used cut-off points from the literature: (1) 12 hours or less, (2) between 12 and 24 hours, (3) between 24 and 48 hours, (4) between 48 and 120 hours, and (5) more than 120 hours. Because we consider length of stay a surrogate for adverse outcome causally affected by treatment time, the outcome variable was calculated as the duration of hospitalization following definitive treatment. Time to definitive fixation and its effect on post-treatment length of hospital stay was analyzed using median regression with inverse probability of treatment-weighting (IPTW) to control for confounding factors. Results : Compared to fixation during the first 12 hours after admission, median length of hospital stay was significantly higher (2.77 days; 95% confidence interval, 0.54 to 4.72) when fixation occurred between 48 and 120 hours from admission. Among the other time intervals, only treatment between twelve to twenty-four hours after admission was shown to reduce length of stay (-0.61 days; 95% confidence interval, -1.53 to 0.42) versus the referent interval of the first 12 hours, though this result did not achieve statistical significance. In order to assess the impact of shorter recorded length of stay for deceased patients, sensitivity analysis was conducted excluding all patient that underwent definitive treatment and died. Results were nearly identical for the second analysis, showing a higher post-treatment length of stay estimated for the population treated between 48 and 120 hours versus had they been treated within the first 12 hours from admission (2.53 days, 95% confidence interval, 0.27 to 4.13). Conclusion : Delayed fixation of femoral shaft fractures in patients with multiple injuries between 2-5 days may lead to an increase in adverse outcomes as evidenced by increased median length of hospital stay. This finding supports prior clinical reports of a perilous period where a “second hit” resulting from definitive internal fixation can occur. Whether there is an optimal window for fixation during which physiologic stress of fracture fixation does not adversely lengthen hospital stay should be the subject of future prospective study.

Abstract
Background Traumatic injury induces changes in mediators of inflammation and coagulation, but the pivotal roles of inflammation and coagulation has not been precisely clarified. Therefore we have studied markers of inflammation and coagulation after a standardized musculoskeletal trauma like total hip replacement surgery. Methods We allocated 21 patients aged 50 to 84 years who underwent total hip replacement surgery. Releases of TNF-α, IL-1β, IL-6, IL-8 and IL-10 and protrombin fragment F1.2 and plasmin-antiplasmin complex (PAP) were examined during surgery and up 6 days postoperatively, and systemic releases were compared to pre-operative values. Surgery induced significant increments in serum levels of IL-6 at 6 hours and at 1 day after surgery and in levels of IL-8 at 6 hours after surgery. There were no significant changes in serum levels of TNF-α, IL-1β or IL-10. There were significant increments in blood levels of F1.2 and PAP up to 6 days postoperatively with highest levels at 6 hours after surgery. There were only week correlations between IL-6 and IL-8 and F1.2 and PAP. Conclusion Major musculoskeletal surgery causes changes of the inflammatory, coagulatory and fibrinolytic cascades in stable patients, but with no correlations between inflammation and coagulation and fibrinolysis.

Abstract
PURPOSE AND METHODS External fixation is a safe option for stabilisation of extremity lesions in the polytraumatised patient as well as in fractures with severe soft tissue damage. Nevertheless, long-term-complications are to be expected when external fixation is chosen as a definitive treatment. The purpose of this review article is twofold: primarily, to define the rationale of a procedural change from an external fixator to an intramedullary nail; secondarily, to assess the possible advantages and pitfalls of a single- or two-staged procedure. RESULTS AND CONCLUSIONS External fixation of the femur is recommended in multiply injured patients who are critically ill to avoid an additional inflammatory response caused by the surgical trauma of primary nailing. The conversion towards nailing must be done as soon as the clinical condition of the patient has been stabilised. Stable polytraumatised patients do not benefit from initial stabilisation with an external fixator and should immediately be treated with a definitive osteosynthesis. In tibial fractures, external fixation followed by intramedullary nailing is recommendable in fractures with severe soft tissue injuries. Conversion should be done as soon as the soft tissues allow before pin-tract infections occur and performed in a one-staged procedure.

Abstract
Background: Post-traumatic hypoxemia can deteriorate during operative manipulations. Objectives: In the present study, criteria-based approach was applied to determine optimum conditions for femur surgery. The aim of this study was to optimize perioperative management of post-traumatic hypoxemia. Patients and Methods: In this prospective observational study, post-traumatic adults with PaO2 < 70 mmHg in room air were enrolled. Physiological parameters, O2 saturation (SO2), arterial blood gas (ABG) analysis, Schonfeld fat embolism index score (SS), and Murray’s lung injury scores (LIS) were assessed. The management protocol was femur surgery when patient was hemodynamically stable with LIS < 2.5 and PaO2/FiO2 > 200 mmHg (FiO2 < 0.5, PEEP < 8 cm H2O). Results: A total of 31 adults (26 males and 5 females) with LIS of 0.1 to 2.5 (26 patients) and > 2.5 (five patients) at admission were recruited. Sixteen patients were admitted within 24 hours and 15 between 24 and 90 hours after injury. Thirteen patients were operated within 24 hours. Post-operative LIS was improved. No adverse sequels or mortality were seen. Conclusions: Appropriate surgical stabilization can be safely performed during established post-traumatic hypoxemia using a multidisciplinary approach, continuous monitoring, and serial investigations to diagnose fulminant pathology and associated injuries.

Abstract
INTRODUCTION Surgery is a posttraumatic immune stimulus which contributes to the systemic inflammatory response syndrome and multiple organ failure (MOF). Serum markers may facilitate post-injury immune monitoring, predict complications and guide the timing of surgery. AIM To evaluate whether immune markers increase after surgery in trauma patients, if this is affected by the timing of surgery, and whether immune markers correlate with clinical outcomes. PATIENTS AND METHODS Systematic review of MEDLINE, Cochrane and EMBASE using a combination of keywords including trauma, biological markers, immune monitoring, and surgical procedures. The last search was performed on 26/11/13. The search considered English language studies enrolling adult trauma patients. Outcomes were perioperative immune markers plus clinical outcomes including mortality, MOF, sepsis. RESULTS 1612 Articles were identified using the search strategy. 1548 Articles were excluded by title and 40 excluded by abstract, leaving 24 articles for full text review. Of these articles, fifteen studies were eligible for study inclusion. The disparity in interventions and outcome measures precluded combined statistical analysis. The surgical intervention studied was mostly intramedullary nailing of long bone fractures. All articles described a postoperative increase in at least one marker. Interleukin (IL)-6 and IL-10 were consistently elevated and tested in the greatest number of patients. Many studies did not correlate markers with clinical outcomes and few significant associations were demonstrated. Two studies considered the timing of surgery and showed greater increase in IL-6 after "early" surgery, though definitions of timing were dissimilar. DISCUSSION An increase in posttraumatic serum cytokines has been demonstrated after surgery, but without consistent clinical associations. The timing of surgery may modulate this increase. Future research directions include confirmation of findings in larger populations, clarifying clinical associations, and evaluation of other surgical interventions.

Cytokine levels (IL-4, IL-6, IL-8 and TGFβ) as potential biomarkers of systemic inflammatory response in trauma patients. INTERNATIONAL ORTHOPAEDICS 2014; 38:1303-9.

Abstract
PURPOSE Much research is now being conducted in order to understand the role of cytokines in the development of the inflammatory response following trauma. The purpose of this study was to evaluate whether serum levels of certain cytokines, measured immediately after initial injury, can be used as potential biomarkers for predicting the development and the degree of severity of the systemic inflammatory response (SIRS) in patients with moderate and severe trauma. METHODS We conducted a prospective study with 71 individuals of whom 13 (18.3 %) were healthy controls and 58 (81.7 %) were traumatized orthopaedic patients who were categorized into two groups: 31 (43.6 %) with moderate injuries and 27 (38.1 %) patients with severe orthopaedic trauma. Thirty cc of heparinized blood were drawn from each individual within a few hours after the injury. Serum levels of pro-inflammatory, regulatory and anti-inflammatory cytokines were measured in each individual participant. RESULTS High levels of pro-inflammatory cytokines IL-1β,-6,-8,-12, tumour necrosis factor alpha and interferon gamma were found in all injured patients compared to healthy controls. Only IL-6 and IL-8 were significantly higher in the injured patients. Levels of the regulatory cytokines, transformed growth factor beta (TGF-β) and IL-10 were higher in the injured patients, but significant only for TGF-β. Levels of IL-4 were significantly lower in the injured groups as compared to the controls. CONCLUSIONS Secretion of large amounts of pro-inflammatory cytokines and decreased level of anti-inflammatory cytokines during the acute phase of trauma may lead to the development of systemic inflammatory response syndrome (SIRS) in unstable polytraumatized patients. SIRS may result in life threatening conditions as acute respiratory distress syndrome (ARDS) and multiple organ failure (MOF). High levels of IL-6, IL-8, TGFβ and low levels of IL-4 were found to be reliable markers for the existence of immune reactivity in trauma patients. More research is needed to study pattern of cytokine levels along the acute period of injury, after surgical interventions and during recovery.

Abstract
BACKGROUND Femoral shaft fractures are one of the most common injuries in multiple trauma patients. Due to their prognostic relevance, there is an ongoing controversial discussion as to the optimal treatment strategy in terms of Damage Control Orthopaedics (DCO) and Early Total Care (ETC). We aimed to describe the differences in fracture management and clinical outcome of multiple trauma patients with concomitant femoral shaft fractures treated at a German and an Australian level I trauma centre using the same inclusion criteria. METHODS Polytraumatized patients (ISS ≥ 16) with a femoral shaft fracture aged ≥ 16 years treated at a German and an Australian trauma centre between 2003 and 2007 were included. According to ETC and DCO management principles, we evaluated demographic parameters as well as posttraumatic complications and clinical outcome. RESULTS Seventy-three patients were treated at the German and 134 patients at the Australian trauma centre. DCO was performed in case of increased injury severity in both hospitals. Prolonged mechanical ventilation time, and length of ICU and hospital stay were demonstrated in DCO treatment regardless of the trauma centre. No differences concerning posttraumatic complications and survival were found between both centres. Survival of patients after DCO was similar to those managed using ETC despite a greater severity of injury and lower probability of survival. There was no difference in the incidence of ARDS. DCO was, however, associated with a greatly increased length of time on mechanical ventilation and length of stay in the ICU. CONCLUSION We found no differences concerning patient demographics or clinical outcomes in terms of incidence of ARDS, MODS, or mortality. As such, we propose that comparability between German and Australian trauma populations is justified. Despite a higher ISS in the DCO group, there were no differences in posttraumatic complications and survival depending on ETC or DCO treatment. Further research is required to confirm whether this is the case with other countries, too.

Abstract
BACKGROUND A few animal studies have shown that IL-6 can serve as an early marker of fat embolism syndrome. The degree to which this is true in human trauma victims is unknown. QUESTIONS/PURPOSES In this clinical study, we sought to determine (1) whether elevated serum IL-6 levels at 6, 12, and 24 hours in patients with skeletal trauma were associated with the development of fat embolism syndrome (FES) within 72 hours after injury, and (2) at what time after trauma peak IL-6 levels are observed. METHODS Forty-eight patients between 16 and 40 years old who presented to our tertiary trauma center within 6 hours of injury with long bone and/or pelvic fractures were included in this study. Serum IL-6 levels were measured at 6, 12, and 24 hours after injury. The patients were observed clinically and monitored for 72 hours for development of FES symptoms. Gurd's criteria were used to diagnose FES. RESULTS Elevated serum IL-6 levels 12 hours after trauma correlated with an increased likelihood of having FES develop; no significant relationship was observed between IL-6 levels at 6 or 24 hours and the development of FES. Patients with FES had a mean IL-6 level of 131 pg/mL, whereas those without FES had a mean IL-6 level of 72 pg/mL. Peak IL-6 levels were observed at 12 hours. CONCLUSIONS An elevated serum IL-6 level may be useful as an early marker of FES in patients with isolated skeletal trauma. LEVEL OF EVIDENCE Level II, diagnostic study. See Guidelines for Authors for a complete description of levels of evidence.

Abstract
The management of the polytraumatized orthopedic patient remains a challenging issue. In recent years many efforts have been made to develop rescue techniques and to promote guidelines for the management of these patients. Currently controversies persist between two orthopedic approaches: the Early Total Care and the Damage Control Orthopedics. An overview of the current literature on the orthopedic management of polytrauma patient is provided. Subsequently, femoral shaft fractures, representing extremely common lesions, and pelvic ring injuries, that are associated with a high mortality rate, are analyzed in detail.

Abstract
In poly-traumatic patients, second hits are known to potentiate the posttraumatic systemic inflammatory response, thus increasing the risk of multi-organ dysfunction. In accordance with "damage control orthopaedic surgery" principles, fractures are initially treated with external fixators, which are replaced by internal osteosynthesis once the immunological status of the patient is considered stable. Recently, we demonstrated that a severe trauma impaired the healing of fractures stabilized by external fixation during the entire healing period. The question arose, whether switching to intramedullary nailing increases the inflammatory response in terms of a second hit, leading to a further impairment of bone healing. Wistar rats received a femoral osteotomy stabilized by an external fixator. Simultaneously half of the rats underwent an additional thoracic trauma. After 4 days, the external fixator was replaced by an intramedullary nail in half of the rats of the two groups. The inflammatory response was evaluated by measuring serum C5a levels. Fracture healing was determined by three-point-bending, µCT, and histomorphometry. The thoracic trauma significantly increased C5a concentrations 6, 24, and 72 h after the second surgical intervention. After 40 days, conversion to intramedullary nailing considerably decreased the flexural rigidity of the callus, with no significant differences between rats with or without thoracic trauma. After 47 days, flexural rigidity in rats subjected to conversion remained decreased compared to animals solely treated by external fixation, particularly in combination with blunt chest trauma. The results indicate that accumulation of second hits after multiple injuries could lead to aggravation of the fracture healing outcome.

Abstract
OBJECTIVE To evaluate the rate of systemic complications and mortality in severe polytrauma patients with associated femur fracture treated by early external fixation of femur. PATIENTS AND METHODOLOGY We made a retrospective cohort study with forty-one adult multitrauma patients (New Injury Severity Score ≥ 19) with femur fracture treated by external fixation following Damage Control Orthopaedic surgery. The mortality rates, TRISS analysis, incidence of ARDS and MOF were analysed. RESULTS The mean NISS was 41.2 and the mean age 32.7. 50% of patients were in shock on admission. All patients were treated in the first 12 hours with external fixation. 30% of patients developed ARDS and six patients had MOF. Five patients treated by external fixation died. Difference between predicted mortality by TRISS and actual mortality showed a reduction of 15.9% (0.71 predicted survival versus 0.88 real survival). CONCLUSIONS An aggressive and early Damage Control approach to treat femur fractures in severe polytrauma patients led to low mortality rate comparing to the predicted mortality by TRISS.

Abstract
Musculoskeletal injuries are the most common reason for operative procedures in severely injured patients and are major determinants of functional outcomes. In this paper, we summarise advances and future directions for management of multiply injured patients with major musculoskeletal trauma. Improved understanding of fracture healing has created new possibilities for management of particularly challenging problems, such as delayed union and non union of fractures and large bone defects. Optimum timing of major orthopaedic interventions is guided by increased knowledge about the immune response after injury. Individual treatment should be guided by trading off the benefits of early definitive skeletal stabilisation, and the potentially life-threatening risks of systemic complications such as fat embolism, acute lung injury, and multiple organ failure. New methods for measurement of fracture healing and function and quality of life outcomes pave the way for landmark trials that will guide the future management of musculoskeletal injuries.

Abstract
The management of polytrauma has evolved considerably in the last century. Advances have been made in all disciplines involved in trauma care from pre-hospital care and resuscitation protocols to diagnostics, surgical techniques, administration of novel pharmacological agents and late reconstruction procedures. Improved understanding of the altered physiology and the induced response at the molecular level offers the potential for novel management strategies and prevention of post-traumatic complications.

Abstract
Parkinson's disease (PD) is a neurodegenerative disorder characterized by the loss of nigrostriatal dopaminergic neurons and the accumulation of alpha-synuclein. Both traumatic brain injury (TBI) and pesticides are risk factors for PD, but whether TBI causes nigrostriatal dopaminergic cell loss in experimental models and whether it acts synergistically with pesticides is unknown. We have examined the acute and long-term effects of TBI and exposure to low doses of the pesticide paraquat, separately and in combination, on nigrostriatal dopaminergic neurons in adult male rats. In an acute study, rats received moderate TBI by lateral fluid percussion (LFP) injury, were injected with saline or paraquat (10 mg/kg IP) 3 and 6 days after LFP, were sacrificed 5 days later, and their brains processed for immunohistochemistry. TBI alone increased microglial activation in the substantia nigra, and caused a 15% loss of dopaminergic neurons ipsilaterally. Paraquat increased the TBI effect, causing a 30% bilateral loss of dopaminergic neurons, reduced striatal tyrosine hydroxylase (TH) immunoreactivity more than TBI alone, and induced alpha-synuclein accumulation in the substantia nigra pars compacta. In a long-term study, rats received moderate LFP, were injected with saline or paraquat at 21 and 22 weeks post-injury, and were sacrificed 4 weeks later. At 26 weeks post injury, TBI alone induced a 30% bilateral loss of dopaminergic neurons that was not exacerbated by paraquat. These data suggest that TBI is sufficient to induce a progressive degeneration of nigrostriatal dopaminergic neurons. Furthermore, TBI and pesticide exposure, when occurring within a defined time frame, could combine to increase the PD risk.

Intramedullary nailing of femoral shaft fractures in polytraumatized patients. a longitudinal, prospective and observational study of the procedure-related impact on cardiopulmonary- and inflammatory responses. Scand J Trauma Resusc Emerg Med 2012; 20:2. [PMID: 22221511 PMCID: PMC3285514 DOI: 10.1186/1757-7241-20-2] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2011] [Accepted: 01/05/2012] [Indexed: 02/10/2023] Open
Abstract
BACKGROUND Early intramedullary nailing (IMN) of long bone fractures in severely injured patients has been evaluated as beneficial, but has also been associated with increased inflammation, multi organ failure (MOF) and morbidity. This study was initiated to evaluate the impact of primary femoral IMN on coagulation-, fibrinolysis-, inflammatory- and cardiopulmonary responses in polytraumatized patients. METHODS Twelve adult polytraumatized patients with femoral shaft fractures were included. Serial blood samples were collected to evaluate coagulation-, fibrinolytic-, and cytokine activation in arterial blood. A flow-directed pulmonary artery (PA) catheter was inserted prior to IMN. Cardiopulmonary function parameters were recorded peri- and postoperatively. The clinical course of the patients and complications were monitored and recorded daily. RESULTS Mean Injury Severity Score (ISS) was 31 ± 2.6. No procedure-related effect of the primary IMN on coagulation- and fibrinolysis activation was evident. Tumor necrosis factor alpha (TNF-α) increased significantly from 6 hours post procedure to peak levels on the third postoperative day. Interleukin-6 (IL-6) increased from the first to the third postoperative day. Interleukin-10 (IL-10) peaked on the first postoperative day. A procedure-related transient hemodynamic response was observed on indexed pulmonary vascular resistance (PVRI) two hours post procedure. 11/12 patients developed systemic inflammatory response syndrome (SIRS), 7/12 pneumonia, 3/12 acute lung injury (ALI), 3/12 adult respiratory distress syndrome (ARDS), 3/12 sepsis, 0/12 wound infection. CONCLUSION In the polytraumatized patients with femoral shaft fractures operated with primary IMN we observed a substantial response related to the initial trauma. We could not demonstrate any major additional IMN-related impact on the inflammatory responses or on the cardiopulmonary function parameters. These results have to be interpreted carefully due to the relatively few patients included. TRIAL REGISTRATION ClinicalTrials.gov: NCT00981877.

The effect of C1-esterase inhibitor on systemic inflammation in trauma patients with a femur fracture - The CAESAR study: study protocol for a randomized controlled trial. Trials 2011; 12:223. [PMID: 21988742 PMCID: PMC3198691 DOI: 10.1186/1745-6215-12-223] [Citation(s) in RCA: 12] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2011] [Accepted: 10/11/2011] [Indexed: 01/21/2023] Open
Abstract
Background Systemic inflammation in response to a femur fracture and the additional fixation is associated with inflammatory complications, such as acute respiratory distress syndrome and multiple organ dysfunction syndrome. The injury itself, but also the additional procedure of femoral fixation induces a release of pro-inflammatory cytokines such as interleukin-6. This results in an aggravation of the initial systemic inflammatory response, and can cause an increased risk for the development of inflammatory complications. Recent studies have shown that administration of the serum protein C1-esterase inhibitor can significantly reduce the release of circulating pro-inflammatory cytokines in response to acute systemic inflammation. Objective Attenuation of the surgery-induced additional systemic inflammatory response by perioperative treatment with C1-esterase inhibitor of trauma patients with a femur fracture. Methods The study is designed as a double-blind randomized placebo-controlled trial. Trauma patients with a femur fracture, Injury Severity Score ≥ 18 and age 18-80 years are included after obtaining informed consent. They are randomized for administration of 200 U/kg C1-esterase inhibitor intravenously or placebo (saline 0.9%) just before the start of the procedure of femoral fixation. The primary endpoint of the study is Δ interleukin-6, measured at t = 0, just before start of the femur fixation surgery and administration of C1-esterase inhibitor, and t = 6, 6 hours after administration of C1-esterase inhibitor and the femur fixation. Conclusion This study intents to identify C1-esterase inhibitor as a safe and potent anti-inflammatory agent, that is capable of suppressing systemic inflammation in trauma patients. This might facilitate early total care procedures by lowering the risk of inflammation in response to the surgical intervention. This could result in increased functional outcomes and reduced health care related costs. Trial registration clinicaltrials.gov NCT01275976 (January 12th 2011)

Abstract
The evolution of contemporary intramedullary reaming systems has recently generated the Reamer Irrigator Aspirator system (RIA-Synthes®), which has progressively gained in popularity as well as in indications. The preliminary results of its use over the initial period of 18 months ata single tertiary referral centre were prospectively collected and are presented. The wide spectrum of RIA's indications have been exploited, including 7 patients with polytrauma that underwent acute femoral nailing, 8 with femoral intramedullary osteomyelitis, 9 with pathological lesions of the femoral shaft, as well as 18 patients where the RIA system has been used to harvest morselised autologous bone graft in the presence of recalcitrant atrophie non-unions and bone defects. Overall its use was proven safe and efficient, achieving aggressive medullary canal debridement, collection of adequate samples for further analysis in the infected and oncology cases, as well as impressive volumes of the osteoinductive and osteogenic reaming debris for grafting purposes. No pulmonary complications or evidence of the second hit sequelae were recorded in the polytrauma patient subgroup despite the presence of a high ISS Further controlled clinical studies should follow focused in all different applications of this reliable, user-friendly and impressively versatile system, to validate these preliminary results.

Abstract
The last two decades extensive research evidence has been accumulated regarding the pathophysiology of trauma and the sequelae of interventions that follow. Aim of this analysis has been to collect and categorise the existing data on the so-called "second hit" phenomenon that includes the biochemical and physiologic alterations occurring in patients having surgery after major trauma. Articles were extracted from the PubMed database and the retrieved reports were included in the study only if pre-specified eligibility criteria were fulfilled. Moreover, a constructed questionnaire was utilised for quality assessment of the outcomes. Twenty-six articles were eligible for the final analysis, referring to a total of 8262 patients that underwent surgery after major trauma. Sixteen retrospective clinical studies including 7322 patients and 10 prospective ones, including 940 patients were evaluated. Several variables able to reproduce a post-operative second hit were identified; mostly related to pulmonary dysfunction, coagulopathy, fat or pulmonary embolism, and the inflammatory immune system. Indicative conclusions were extracted, as well as the need for further prospective randomised trials. Suggestions on the content and the rationale of future studies are provided.

Coagulation, fibrinolysis and cytokine responses to intramedullary nailing of the femur: an experimental study in pigs comparing traditional reaming and reaming with a one-step reamer-irrigator-aspirator system. Injury 2011; 42:630-7. [PMID: 20650454 DOI: 10.1016/j.injury.2010.06.025] [Citation(s) in RCA: 12] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/30/2010] [Revised: 06/23/2010] [Accepted: 06/23/2010] [Indexed: 02/02/2023]
Abstract
INTRODUCTION Operations in trauma patients represent a second insult and the extent of the surgical procedures influences the magnitude of the inflammatory response. Our hypothesis was that a reamer-irrigator-aspirator (RIA) system would cause a lesser inflammatory response than traditional reaming (TR). MATERIALS AND METHODS Coagulation, fibrinolysis and cytokine responses were studied in Norwegian landrace pigs during and after intramedullary nailing (IMN) with two different reaming systems using ELISA and chromogenic peptide substrate assays. The TR (n=8) and the RIA (n=7) reaming systems were compared to a control group (n=7). The animals were followed for 72 h. Arterial, mixed venous and femoral vein blood were withdrawn simultaneously peroperatively and until 2 h after the nail was inserted for demonstration of local, pulmonary and systemic activation of the cascade systems. At 6 h, 24 h, 48 h and 72 h postoperatively arterial blood samples were withdrawn. RESULTS Significantly procedure-related increased levels were found for thrombin-antithrombin (TAT) and tissue plasminogen activator (t-PA) in the TR group and TAT in the RIA group. The local and the pulmonary activation of coagulation and fibrinolysis were more pronounced in the TR than in the RIA group, the difference reached significance for plasminogen activator inhibitor-1 (PAI-1) (arterial blood). The cytokine response, mainly represented by IL-6 increase, was more pronounced in the TR than the RIA group, and was significant for IL-6 in femoral vein blood. The arterial levels of IL-6 exceeded the mixed venous levels indicating an additional pulmonary activation of IL-6. Two animals in the TR group, who died of pulmonary embolism (PE) prior to planned study end point, had a more pronounced response compared to the rest of the TR group. CONCLUSION A procedure-related coagulation and fibrinolytic response was demonstrated in both reaming groups, with more pronounced response in the TR than in the RIA group. Elevated levels of cytokines were demonstrated related to reaming and nailing, with significantly higher IL-6 levels in the TR than in the RIA group.

Abstract
OBJECTIVE To assess the value of venous serum bicarbonate as an endpoint of resuscitation and guide to timing of femoral nailing in multi-system trauma patients. DESIGN Retrospective cohort study. SETTING Academic Level 1 Trauma Centre. PATIENTS Seventy-two consecutive adult multi-system trauma patients (Injury Severity Score≥15) with femoral shaft fracture (Orthopaedic Trauma Association Class 32-A to 32-C) treated with reamed medullary nail fixation. INTERVENTION Femoral nailing in the setting of hypo-perfusion defined by venous serum bicarbonate (SB). Threshold values of SB were determined first by correlating SB and simultaneously drawn arterial base deficit (BD). Then, corresponding values of SB to previously defined thresholds of hypo-perfusion based on BD were identified using regression analysis. MAIN OUTCOME MEASUREMENT Pulmonary organ dysfunction (POD) component of the Denver Multiple Organ Failure scoring system. RESULTS Simultaneous admission SB and BD values were correlated (r=-0.43, p=0.001). Adjusting for age, ISS and baseline POD, patients with SB<24.7 mequiv./L within 6 h of treatment had a 12-fold increase in POD (OR 12.2, 95% CI 1.5-98.6, p=0.019). This association was diminished, but still significant with hypo-perfusion present within 12 h prior to treatment (OR 5.6, 95% CI 1.0-29.1, p=0.042) and 24 h prior to treatment (OR 5.9, 95% CI 1.1-30.7, p=0.037). CONCLUSIONS Medullary fixation of femoral shaft fracture in the setting of serum bicarbonate-defined hypo-perfusion is associated with increased morbidity. Appropriate damage-control measures and aggressive resuscitation prior to definitive fracture care are advised and physiologic markers such as serum bicarbonate should guide clinical decision making rather than temporal distinctions.

Abstract
BACKGROUND Alcohol is a known modulator of the immune system and host-defense response. Alcohol abuse is common in trauma patients, although the influence of alcohol intoxication on the inflammatory response following major orthopaedic injury remains unknown. The aim of this investigation was to examine the influence of binge alcohol exposure on biomarkers of the systemic inflammatory response following bilateral traumatic femoral fracture in a rodent model. METHODS Ninety-two Sprague-Dawley rats were administered intraperitoneal injections of either saline solution or alcohol for three days. These animals then underwent a sham procedure or bilateral femoral intramedullary pinning and mid-diaphyseal closed fracture via blunt guillotine. The animals were killed at specific time points after the injury. Serum and lung tissue were collected, and twenty-five inflammatory markers were analyzed by immunoassay. Histological sections of lung tissue were evaluated by a board-certified pathologist. RESULTS Bilateral femoral fracture significantly (p < 0.05) increased multiple serum biomarkers of inflammation. Binge alcohol treatment prior to injury significantly suppressed the increase in serum levels of interleukin (IL)-6, white blood cells, IL-2, IL-10, and C-reactive protein after the fracture. However, alcohol-treated animals were found to have increased pulmonary levels of IL-6, IL-1β, IL-2, and macrophage inflammatory protein-1α following bilateral femoral fracture. In addition, lung tissue harvested following alcohol treatment and injury demonstrated increased pathologic changes, including parenchymal, alveolar, and peribronchial leukocyte infiltration and significantly elevated pulmonary wet-to-dry ratio, indicative of pulmonary edema. CONCLUSIONS Our results indicate that acute alcohol intake prior to bilateral femoral fracture with fixation in rats modulates the inflammatory response after injury in a tissue-dependent manner. Although serum biomarkers of inflammation were suppressed in alcohol-treated animals following injury, several measures of pulmonary inflammation including cytokine levels, histological changes, and findings of pulmonary edema were significantly increased following fracture with the presence of alcohol.

Abstract
We evaluated the peripheral release of inflammatory mediators after femoral fracture and subsequent intramedullary reaming using the RIA reamers. IL-6 was elevated after trauma, and reaming with RIA induced a measurable second hit response. However, despite a higher ISS, the levels of IL-6 in the RIA group were similar to the levels measured in a group of patients where reaming of the femoral canal was performed using conventional reamers. There was one death related to fat embolism syndrome in the conventional reamers group. However, the overall incidence of complications was low and similar between the 2 groups of studied patients. In polytrauma patients, large scale studies are desirable to evaluate further the immuno-inflammatory response using the RIA reamers prior to the instrumentation of the femoral canal.
