Poor socioeconomic status is associated with delayed femoral fracture fixation in adolescent patients. Injury 2023; 54:111128. [PMID: 37875032 DOI: 10.1016/j.injury.2023.111128] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/07/2023] [Revised: 10/06/2023] [Accepted: 10/13/2023] [Indexed: 10/26/2023]
Abstract
INTRODUCTION Healthcare disparities continue to exist in pediatric orthopedic care. Femur fractures are the most common diaphyseal fracture and the leading cause of pediatric orthopedic hospitalization. Prompt time to surgical fixation of femur fractures is associated with improved outcomes. OBJECTIVE The objective of this study was to evaluate associations between socioeconomic status and timing of femoral fixation in adolescents on a nationwide level. METHODS The 2016-2020 National Inpatient Sample (NIS) database was queried using International Classification of Disease, 10th edition (ICD-10) codes for repair of femur fractures. Patients between the ages of 10 and 19 years of age with a principal diagnosis of femur fracture were selected. Patients transferred from outside hospitals were excluded. Baseline demographics and characteristics were described. Patients were categorized as poor socioeconomic status (PSES) if they were classified in the Healthcare Cost and Utilization Project's (HCUP) lowest 50th percentile median income household categories and on Medicaid insurance. The primary outcome studied was timing to femur fixation. Delayed fixation was defined as fixation occurring after 24 h of admission. Secondary outcomes included length of stay (LOS) and discharge disposition. RESULTS From 2016-2020, 10,715 adolescent patients underwent femur fracture repair throughout the United States. Of those, 765 (7.1 %) underwent late fixation. PSES and non-white race were consistently associated with late fixation, even when controlling for injury severity. Late fixation was associated with decreased rate of routine discharge (p < 0.01), increased LOS (p < 0.01) and increased total charges (p < 0.01). CONCLUSION Patients of PSES or non-white race were more likely to experience delayed femoral fracture fixation. Delayed fixation led to worse outcomes and increased healthcare resource utilization. Research studying healthcare disparities may provide insight for improved provider education, implicit bias training, and comprehensive standardization of care.

Developments in the understanding of staging a "major fracture" in polytrauma: results from an initiative by the polytrauma section of ESTES. Eur J Trauma Emerg Surg 2023:10.1007/s00068-023-02245-5. [PMID: 36820896 DOI: 10.1007/s00068-023-02245-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2022] [Accepted: 02/08/2023] [Indexed: 02/24/2023]
Abstract
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.

Minimally invasive treatment of old femoral fractures in adults. Injury 2019; 50:956-961. [PMID: 30878260 DOI: 10.1016/j.injury.2019.03.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2018] [Accepted: 03/02/2019] [Indexed: 02/02/2023]
Abstract
OBJECTIVE Extensive incision associated with large-scale callus exfoliation and internal fixation is the common therapeutic approach employed by the majority of orthopaedists in the treatment of old femoral fractures. Inspired by the surgical techniques of intramedullary fixation and reduction by traction, the present study attempted to treat old femoral fractures with minimally invasive methods utilising the principles of biological osteosynthesis (BO). METHODS A retrospective analysis involving 16 patients with old femoral fractures treated with combined traction, small incision, limited callus treatment, reduction by leverage and intramedullary fixation was conducted. The operative effect was evaluated by the operation time, intraoperative blood loss, bone grafting, healing time of fractures during follow-up, VAS score, and Harris hip score. RESULTS Intraoperative observation revealed an average operation time of 1.53 ± 0.34 h and average blood loss of 268.13 ± 97.29 ml without bone grafting in all patients. All enrolled patients had outcomes resulting in effective fixation restoration of limb alignment. Of the 16 enrolled patients, 13 patients completed follow-up with an average follow-up time of 7.42 ± 3.29 months. The average healing time for proximal femoral fractures was 3 months. The average healing time of femoral shaft fractures was 4 ± 1.09 months; two of these cases took 4 months to heal, whereas 1 case demonstrated a delayed healing time of 6 months. The VAS score was 1.15 ± 1.70, 1 patient experienced sciatica, and the Harris hip score was 92.92 ± 5.42. There were no complications of malunion, nonunion or infection among any of the patients who completed follow-up. CONCLUSIONS Minimally invasive treatment is feasible for most patients with old femoral fractures of the trochanter and femoral shaft. This finding is consistent with BO principles, thereby providing a possible new method for the treatment of old femoral fractures.

Early versus late intramedullary nailing for traumatic femur fracture management: meta-analysis. J Orthop Surg Res 2018; 13:160. [PMID: 29954434 PMCID: PMC6022515 DOI: 10.1186/s13018-018-0856-4] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2018] [Accepted: 06/05/2018] [Indexed: 01/30/2023] Open
Abstract
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.

Early intramedullary nailing for femoral fractures in patients with severe thoracic trauma: A systemic review and meta-analysis. Chin J Traumatol 2016; 19:160-3. [PMID: 27321297 PMCID: PMC4908231 DOI: 10.1016/j.cjtee.2016.04.001] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/20/2015] [Revised: 12/04/2015] [Accepted: 12/10/2015] [Indexed: 02/04/2023] Open
Abstract
PURPOSE Early intramedullary nailing (IMN) within the first 24 h for multiply injured patients with femoral fracture and concomitant thoracic trauma is controversial. Previously published studies have been limited in size and their outcomes have been inconclusive. A meta-analysis was conducted to evaluate the available data in order to guide care and help improve the outcomes for these patients. METHODS We searched the literature up to December 2011 in the main medical search engines and identified 6 retrospective cohort studies that explored the safety of early IMN in patients with both femoral fracture and chest injury. Our primary outcome was the rates of pulmonary complication (pneumonia, adult respiratory distress syndrome, fat embolism syndrome), multiple organ failure (MOF) and mortality. RESULTS We found no statistically significant difference in the rate of pulmonary complications, MOF or mortality in the patients treated with early IMN. CONCLUSION Early IMN for femoral fractures does not increase the mortality and morbidity in chest- injured patients in the studies analyzed.

Timing of Femoral Shaft Fracture Fixation Affects Length of Hospital Stay in Patients with Multiple Injuries. Open Orthop J 2015; 9:324-31. [PMID: 26312117 PMCID: PMC4541315 DOI: 10.2174/1874325001509010324] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/21/2015] [Revised: 04/26/2015] [Accepted: 05/18/2015] [Indexed: 11/22/2022] Open
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 Optimal surgical timing for definitive treatment of femur fractures in severely injured patients remains controversial. This study was performed to examine in-hospital mortality for patients with femur fractures with regard to surgical timing, Injury Severity Score (ISS), and age. METHODS The National Trauma Data Bank version 7.0 was used to evaluate in-hospital mortality for patients presenting with unilateral femur fractures. Patients were stratified into four groups by surgical timing (ST) and four groups by ISS. χ tests were used to evaluate baseline interrelationships. Binary regression was used to examine the association between time to surgery, ISS score, age, and mortality after adjusting for patient medical comorbidities, and personal demographics. RESULTS A total of 7,540 patients met inclusion criteria, with a 1.4% overall in-hospital mortality rate. For patients with an isolated femur fracture, surgical delay beyond 48 hours was associated with nearly five times greater mortality risk compared with surgery within 12 hours (adjusted relative risk, 4.8; 95% confidence interval, 1.6-14.1). Only severely injured patients (ISS, 26+) had higher associated mortality with no delay in surgical fixation (ST1 < 12 hours) relative to ST2 of 13 hours to 24 hours with an adjusted relative risk of 4.2 (95% confidence interval, 1.0-16.7). The association between higher mortality rates and surgical delay beyond 48 hours was even stronger in the elderly patients. CONCLUSION This study supports the work of previous authors who reported that early definitive fixation of femur fractures is not only beneficial, particularly in the elderly, but also consistent with more recent studies recommending at least 12-hour to 24-hour delay in fixation in severely injured patients to promote better resuscitation. LEVEL OF EVIDENCE Therapeutic study, level III.

Cytokine productive capacity of alveolar macrophages and Kupffer cells after femoral fracture and blunt chest trauma in a murine trauma model. Immunol Lett 2013; 152:159-66. [PMID: 23735227 DOI: 10.1016/j.imlet.2013.05.012] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2013] [Revised: 05/08/2013] [Accepted: 05/26/2013] [Indexed: 10/26/2022]
Abstract
INTRODUCTION Specific cellular and inflammatory factors that contribute to the severity of pulmonary dysfunction after blunt chest trauma and osteosynthesis of femoral fractures are yet not fully understood. Therefore, we investigated alterations of the cytokine productive capacity of alveolar macrophages (AM) and Kupffer cells (KC) after femoral fracture stabilized with intramedullary pin with or without blunt chest trauma. MATERIALS AND METHODS In male C57BL/6N mice an intramedullary pin was implanted in an intact femur as the sham procedure. In trauma groups mice either received an isolated femoral fracture with subsequent fracture stabilization with an intramedullary pin (group Fx) or a combined trauma of blunt chest trauma and femur fracture also stabilized by an intramedullary pin (group TTFx). Animals were sacrificed 0h, 6h, 12h, 24h and 3d after trauma induction. Cytokine concentrations were measured in plasma and supernatant of cultivated AM and KC by FACS analysis. Pulmonary and hepatic infiltration of polymorphonuclear leukocytes (PMN) was determined by Ly6G-staining. RESULTS At 6h, isolated femoral fracture with intramedullary stabilization resulted in a significantly increased productive capacity of KC (IL-6, TNF-α, CCL2, CCL3, CCL5 and CCL7) compared to sham animals. Combined trauma additionally resulted in an increased productive capacity of AM (IL-6, TNF-α, CCL2, CCL3, CCL4, CCL5 and CCL7) at 6h and the effect was prolonged up to 3d compared to controls. Combined trauma also led to a significant higher amount of plasma CCL2 at 3d and plasma CCL7 at 6h after the insult compared to group Fx. Compared to shams, pulmonary and hepatic infiltrations of PMNs were increased in group Fx and TTFx after 6h, but in the combined trauma model the effect was prolonged up to 3d. CONCLUSION An intramedullary stabilized femur fracture alone results in a significant activation of the immune response. The combination of femoral fracture and blunt chest trauma however, results in an increased and prolonged activation of the inflammatory response. Transferred to the clinical setting, these results emphasize the critical role of severe chest trauma for treatment strategies of femoral fractures in multiple trauma patients.

Abstract
BACKGROUND Type and timing of treatment of femur fractures is controversial. Although reported as safe and effective in many reports, others have suggested that early definitive stabilization may cause complications, particularly in patients with chest and head injuries. Damage control orthopedics was proposed as an alternative in unstable patients. This study examines the effects of timing of fixation and investigates risk factors for complications. METHODS Seven hundred fifty patients with femur fractures treated between 1999 and 2006 were reviewed. Skeletally mature patients with mean age 35.8 years and mean Injury Severity Score (ISS) 23.7 were included. Four hundred ninety-two patients had ISS ≥18. Early stabilization (n = 656) was defined as definitive treatment of the femur fracture within 24 hours of injury. RESULTS Early definitive stabilization in patients with multiple injuries was associated with fewer complications than delayed stabilization (18.9% vs. 42.9%, p < 0.037) after adjusting for patient age and ISS. Early treatment was also associated with shorter hospital stay, intensive care unit stay, and ventilator days (p < 0.001). Severe (Abbreviated Injury Scale score ≥3) abdominal injury was associated with more complications than severe head (Glasgow Coma Scale score ≤8) and chest (Abbreviated Injury Scale score ≥3) injuries (44.2% vs. 40.9%, p = 0.68, and 34.4%, p = 0.024, respectively) and was an independent risk factor for complications (p < 0.0001). Chest injury was an independent risk factor for pulmonary complications (p < 0.001), but surgical delay in patients with chest injury was also associated with pulmonary complications (p = 0.04). More sepsis was noted patients with severe head injury (22.7% vs. 4.5%, p = 0.037) or severe chest injury (10.2% vs. 2.5%, p = 0.044) when treated on a delayed basis. More patients transferred from other hospitals were treated on a delayed basis (48.9% vs. 37.5%, p = 0.04). CONCLUSIONS Early definitive stabilization is associated with acceptably low rates of complications and is safe in most patients with multiple injuries, including some with severe abdominal, chest, or head injuries with attention to resuscitation before surgery. More complications and longer hospital stay were noted with delayed fixation after adjusting for age and ISS. Chest injury was associated with pulmonary complications; however, the presence of severe abdominal injury was the greatest risk factor for complications. Expediting access to definitive care may reduce complications and expenses.

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.

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 We aimed to determine the effect of femur fractures on mortality, pulmonary complications, and adult respiratory distress syndrome (ARDS). In addition, we aimed to compare the effect of femur fractures with other major musculoskeletal injuries and to determine the effect of timing to surgery on these complications. METHODS All patients were identified from the trauma registries of two Level I trauma centers. Outcomes were defined at mortality in hospital, pulmonary complications, and ARDS in hospital. Regression analysis was used to determine the effect of femur fractures, while controlling for age, Abbreviated Injury Scales, Glasgow Coma Scale, and systolic blood pressure at presentation. We compared femur fractures with other major musculoskeletal injuries in similar models. Within the patients with femur fracture, time to surgery (< 8 hours, 8 hours to 24 hours, and > 24 hours) was evaluated using similar regression analysis. RESULTS Of the total 90,510 patients, 3,938 (4.35%) died in the hospital, 2,055 (2.27%) had a pulmonary complication, and 285 (0.31%) developed ARDS. Femur fracture is statistically predictive of mortality (odds ratio [OR], 1.606; 95% confidence interval [CI], 1.288-2.002) and pulmonary complications (OR, 1.659; 95% CI, 1.329-2.070), when controlling for other injury factors. This was comparable with the effect of pelvic fracture and other major musculoskeletal injuries. Femur fracture had a strong relationship with ARDS (OR, 2.129; 95% CI, 1.382-3.278). Patients treated in the 8 hours to 24 hours window had the lowest mortality risk (OR, 0.140; 95% CI, 0.052-0.375), and there was a trend to increased risk of ARDS in a delay to surgery of > 24 hours. CONCLUSIONS Femur fractures are a major musculoskeletal injury and increase the risk of mortality and pulmonary complications as much as any other musculoskeletal injuries. There is a unique relationship between ARDS and femur fractures, and this must be considered carefully in treatment planning for these patients.

Intramedullary nailing as a 'second hit' phenomenon in experimental research: lessons learned and future directions. Clin Orthop Relat Res 2010; 468:2514-29. [PMID: 20012236 PMCID: PMC2919890 DOI: 10.1007/s11999-009-1191-1] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/18/2009] [Accepted: 11/23/2009] [Indexed: 01/31/2023]
Abstract
BACKGROUND The 'second hit' phenomenon is based on the fundamental concept that sequential insults, which are individually innocuous, can lead to overwhelming physiologic reactions. This response can be expressed in several organic systems and can be examined by measurement of several parameters. PURPOSES The purpose of this study was to evaluate the incidence of systemic effects of intramedullary nailing and the role of concurrent head and thoracic injuries as they have been recorded in vivo. We also wanted to determine what would be the optimal animal model for future research and what variables should be investigated. METHODS We reviewed the available literature of animal studies that used surgery, and particularly nailing, as a second hit. The reviewed studies were retrieved through an electronic search of the MEDLINE database. We analyzed the methods of creating the first and second hits (nailing), the characteristics of the animal models, the variables examined, and the pathophysiologic responses, which appeared after the second hit. RESULTS Second hit reamed intramedullary nailing was found to provoke consumption of coagulation factors, whereas the effect of unreamed nailing on coagulation factors appears inconsistent. Hemodynamic factors were affected only transiently by the second hit, whereas the pulmonary function was affected only when the first hit included lung injury. CONCLUSIONS Thoracic and head injuries predispose to an aggravated second hit. Primate animal models are considered to be closer to clinical reality and should be preferred for future studies. Future studies should include measurements of proinflammatory and antiinflammatory markers.

Abstract
A review of prospectively collected data in our trauma unit for the years 1998-2003 was undertaken. Adult patients who suffered multiple trauma with an Injury Severity Score (ISS) of >/=16, admitted to hospital for more than 72 hours and with sustained blunt chest injuries were included in the study. Demographic details including pre-hospital care, trauma history, admission vital signs, blood transfusions, details of injuries and their abbreviated injury scores (AIS), operations, length of intensive care unit and hospital stays, Injury Severity Score (ISS) and mortality were analysed. Fulfilling the inclusion criteria with at least one chest injury were 1,164 patients. The overall mortality reached 18.7%. As expected, patients in the higher AIS groups had both a higher overall ISS and mortality rate with one significant exception; patients with minor chest injuries (AIS(chest) = 1) were associated with mortality comparable to injuries involving an AIS(chest) = 3. Additionally, the vast majority of polytraumatised patients with an AIS(chest) = 1 died in ICU sooner than patients of groups 2-5.

Abstract
BACKGROUND Fractures of the femoral shaft are common and have potentially serious consequences in patients with multiple injuries. The appropriate timing of fracture repair is controversial. The purpose of the present study was to assess the effect of timing of internal fixation on mortality in patients with multisystem trauma. METHODS We performed a retrospective cohort study with use of data from public and private trauma centers throughout the United States that were reported to the National Trauma Data Bank (version 5.0 for 2000 through 2004). The study included 3069 patients with multisystem trauma (Injury Severity Score, > or =15) who underwent internal fixation of a femoral shaft fracture. The time to treatment was defined in categories as the time from admission to internal fixation: t(0) (twelve hours or less), t(1) (more than twelve hours to twenty-four hours), t(2) (more than twenty-four hours to forty-eight hours), t(3) (more than forty-eight hours to 120 hours), and t(4) (more than 120 hours). The relative risk of in-hospital mortality when the four later periods were compared with the earliest one was estimated with inverse probability of treatment-weighted analysis. Subgroups with serious head or neck, chest, abdominal, and additional extremity injury were investigated. RESULTS When compared with that during the first twelve hours after admission, the estimated mortality risk was significantly lower in three time categories: t(1) (relative risk, 0.45; 95% confidence interval, 0.15 to 0.98; p = 0.03), t(3) (relative risk, 0.58; 95% confidence interval, 0.28 to 0.93; p = 0.03), and t(4) (relative risk, 0.43; 95% confidence interval, 0.10 to 0.94; p = 0.03). Patients with serious abdominal trauma (Abbreviated Injury Score, > or =3) experienced the greatest benefit from a delay of internal fixation beyond twelve hours (relative risk, 0.82 [95% confidence interval, 0.54 to 1.35] for patients with an Abbreviated Injury Score of <3, compared with 0.36 [95% confidence interval, 0.13 to 0.87] for those with an Abbreviated Injury Score of > or =3) (p value for effect modification, 0.09). CONCLUSIONS Delayed repair of femoral shaft fracture beyond twelve hours in patients with multisystem trauma, which may allow time for appropriate resuscitation, reduces mortality by approximately 50%. Patients with serious abdominal injury benefit most from delayed treatment. These results support delaying definitive treatment of long-bone injuries in patients with multisystem trauma as a means of so-called damage-control in order to reduce adverse outcomes.

Abstract
In the treatment of polytrauma patients, multiple studies have shown how the timing and the type of the initial surgery of long bone fractures influence the incidence of systemic complications. Database analyses documented that unduly long surgical procedures undertaken early after trauma increase the risk of acute respiratory distress syndrome (ARDS), especially when femoral shaft fractures are stabilized. Animal research and prospective clinical studies also support the fact that the type of stabilization of a femoral shaft fracture may influence the systemic response to trauma. Reamed intramedullary reaming and nailing for a femoral shaft fracture is associated with an increased risk of pulmonary fat embolization from the medullary canal. This can result in pulmonary compromise if certain cofactors are also present. Modified reamers have been developed to reduce this side effect. The mediating effects are immunologic changes, varying according to the magnitude of the surgical procedure. Pro-inflammatory markers (e.g., Interleukins) may be used to assess the inflammatory response to injury as well as the magnitude of surgery and the systemic impact induced by surgery. Serum levels of such markers can be used clinically to tailor the amount of surgery that is performed to the clinical condition of the patient. The potentially negative impact of excessive surgery in high-risk patients can be avoided by using a new grading system for the assessment of the clinical status of the injured patient. Most recently, a large prospective randomized multicenter study has documented that this grading system is effective for identifying these borderline patients, and that in the borderline patient a staged surgical approach, such as temporary femoral stabilization with an external fixator, reduces the incidence of systemic complications. This work has changed the surgical management of multiply injured patients toward an approach that is tailored to the clinical condition of the patient, as indicated by well-defined clinical parameters as well as objective measurements of serum cytokine levels.

Abstract
OBJECTIVE The purpose of this study was to evaluate the use of retrograde nailing to treat patients with bilateral femur fractures. DESIGN AND SETTING A retrospective review of prospectively obtained trauma databases was completed at 9 Level 1 trauma centers. PATIENTS In all, 3767 patients with femur fractures were identified. Of those, 89 (46 males, 43 females) had bilateral femur fractures treated with reamed, retrograde intramedullary nails within 48 hours after injury. The charts were reviewed for pertinent data. RESULTS The average cohort age was 30 years (16-63 years). The average Injury Severity Score was 21 (9-50). Eighty-five patients (96%) had associated injuries. Thirteen patients (14.6%) developed adult respiratory distress syndrome; 8 had thoracic injuries. There were 4 patients (4%) with fat embolism syndrome, 2 were delayed longer than 24 hours to the operating room. There were 5 deaths (5.6% mortality) in the retrograde nailing group. Thoracic injury was found to be associated with death rate (P < 0.07). CONCLUSIONS Bilateral femur fractures are indicative of severe injuries with mortality rates as high as 40%. There are no specific studies addressing the outcomes of bilateral femur fractures treated with retrograde nailing. In this largest retrospective study to date, the overall death rate of 5.6% was significantly lower than historical controls. The effect of timing and duration of surgery and other injuries is not completely known. In conclusion, retrograde nailing of bilateral femur fractures is an acceptable treatment for bilateral femur fractures.

Abstract
BACKGROUND The timing of fixation of femoral fractures in multiply injured patients with severe thoracic trauma is discussed controversially. Some authors recommend damage control surgery, whereas other authors prefer early definitive treatment. The aim of our study was to investigate the effect of early definitive fixation of femoral fractures on outcomes in multiply injured patients with severe thoracic trauma. METHODS Between May 1, 1998 and December 31, 2004, 578 severely injured patients were admitted to our institution. Forty-five patients met the inclusion criteria for the study cohort (severe thoracic trauma and femoral fracture stabilized with unreamed intramedullary nailing [IMN] within the first 24 hours) and 107 patients were selected for the control cohort (severe thoracic trauma without any lower extremity fracture). Inclusion criteria for both cohorts were age 15 to 55 years with blunt trauma (e.g. motor vehicle collisions, falls) including severe thoracic trauma (Abbreviated Injury Scale [AIS] score >or=3) and Injury Severity Score (ISS) >or=18. For comparison between the cohorts data on patients status (Glasgow Coma Scale score at arrival, Revised Trauma Score, Trauma and Injury Severity Score survival prognosis, Simplified Acute Physiology Score II score), treatment (intubation rate, thoracic drainage, surgery), and outcomes (duration of intensive care unit stay and ventilation, rate of adult respiratory distress syndrome [ARDS], multiple organ failure syndrome [MOFS], and mortality) were selected from hospital databases. Dichotomous data were analyzed by chi test; continuous data were analyzed by Student's t test. Any values of p < 0.05 were considered significant for any test. RESULTS Both cohorts were comparable with regard to demographic data, ISS, AIS score in the thoracic region, and incidence and severity of brain injury. There was no difference in dependent parameters in both cohorts. Rates of ARDS, MOFS, and mortality were not negatively influenced by early unreamed IMN. CONCLUSION Early unreamed IMN of femoral fractures in multiply injured patients with severe thoracic trauma is a safe procedure and seems to be justified to achieve early definitive care.

Abstract
OBJECTIVE To compare the rate of Acute Respiratory Distress Syndrome (ARDS) in multiply injured patients with femoral shaft fractures, treated with intramedullary femoral nails inserted with or without reaming. DESIGN Prospective, randomized, multicenter, clinical trial. SETTING Seven Level 1 trauma centers. PATIENTS Three hundred fifteen patients with 322 femoral shaft fractures were stratified into 2 groups according to their estimated injury severity scores (ISS > or =18 vs. ISS<18) and then randomized to receive an IM nail with either reamed or unreamed insertion for primary stabilization of their femoral shaft fracture. One hundred forty seven patients with 151 fractures received an unreamed nail whereas 168 patients with 171 fractures, received a reamed nail. All fractures were nailed within 24 hours after their trauma. INTERVENTION Closed intramedullary nailing for femoral shaft fractures. MAIN OUTCOME MEASUREMENTS Determination of the rate of ARDS in patients undergoing intramedullary nailing of femoral shaft fractures. RESULTS Three of the 63 multiply injured patients who received a reamed nail developed ARDS as compared with 2 out of 46 patients in the unreamed group. This difference was not statistically significant (P=0.42). (The power for this difference is only 5%. 39,817 patients are needed in each group to detect a difference that small.) This difference was not statistically significant. There were a total of 4 deaths, 2 each in both the reamed and unreamed group. No death resulted from ARDS. CONCLUSIONS The overall incidence of ARDS was found to be low with primary stabilization of femoral shaft fractures with intramedullary nailing. There was no difference in the incidence of ARDS between the reamed and unreamed groups, given the sample size.

Abstract
BACKGROUND Post-traumatic MOF results from local tissue injury because of migration and activation of dysfunctional polymorphonuclear leukocytes (PMN). Although fracture surgery exacerbates the postinjury inflammatory response, it is usually beneficial. This study compared changes in PMN receptor expression and migratory activity, in whole blood and following PMN isolation. METHODS IL-8 mediated PMN migration and expression of CXCR-1, CD11b, and CD18 was studied in isolated and whole blood PMN in normal controls. Migration was studied at admission and day 5 after surgery in trauma patients undergoing fracture surgery. RESULTS PMN isolation results in increased expression of surface receptors and enhanced migration in normal controls. In trauma patient samples, isolated PMN migration is enhanced after injury, but suppressed when migration from whole blood is studied, both after injury and fracture surgery. CONCLUSION PMN isolation results in priming for migration, which has a relatively greater impact upon PMN in trauma patients. The observation that PMN activity may decline but priming potential remains enhanced is novel. Further refinements of whole blood and isolated PMN techniques are clearly warranted. This may help to resolve the mismatch in clinical and scientific experience in those patients with major fractures requiring surgical stabilization.

Abstract
BACKGROUND Femur-shaft fracture treatment (FSFT) follows controversial management concepts after multiple trauma: primary-definitive osteosynthesis, secondary-definitive osteosynthesis after temporary external fixation (EF) in all patients, or individualized primary- or secondary-definitive osteosynthesis ("risk-adapted damage control orthopedics"). This study compares the concepts by analyzing literature evidence and a prospective multicenter database. METHODS A systematic literature analysis was performed. The German Trauma Society trauma registry was used to assess variables predictive of treatment concept. RESULTS Contradictory results in 63 controlled trials failed to support a "generalized management strategy." In all, 1,465 FSFTs in 8,057 trauma registry patients (age 39 +/- 19.5 years; Injury Severity Score [ISS] 23.5 +/- 14.9; 17.3% mortality) were treated initially (<24 hour) by EF, nail, or plate in 47.0%, 41.1%, and 11.9%, respectively. Despite large interhospital variability, EF was more likely with increasing severity of ISS, Glasgow Coma Score, thorax trauma, base excess, coagulation abnormalities, and initial probability of death. CONCLUSIONS Clinical "reality" reflects the controversies of "scientific evidence" for FSFT after multiple trauma in Germany. Although decision making is currently based on unvalidated criteria, anatomic and physiologic injury severity appears to influence the choice of management concept.

Abstract
An 18-year-old male patient sustained right-sided femoral and 2nd degree open tibial shaft fractures following a motorcycle accident. Further injuries, and thoracic injury in particular, were excluded clinically and radiologically. Early stabilization of the fractures was achieved by external fixation of the tibia followed by unreamed femoral nailing.Postoperatively, severe deterioration of pulmonary function led to the progressive development of an adult respiratory distress syndrome (ARDS) and necessitated extracorporal membrane oxygenation (ECMO) of the ventilated patient for 89 h. Subsequently, the patient's gas exchange parameters improved allowing extubation 1 week after the accident. Secondary tibia nailing and further recovery of the patient were uneventful.

Abstract
Early stabilization of major long bone fractures is beneficial in reducing the incidence of acute respiratory distress syndrome and multiple organ failure, both of which are caused by activation of the systemic inflammatory response. This activation results in tissue recruitment of and injury by circulating polymorphonuclear leukocytes. The reasons for clinical benefits of early fracture stabilization in major trauma are unknown. Published studies indicate that fracture surgery increases the posttraumatic inflammatory response. Major surgery to stabilize fractures carries a higher complication rate when performed on patients whose hypovolemic shock is not fully corrected. Thus, fracture care should be tailored to the patient, not dictated by the injured bone. Understanding the impact of fracture surgery on the systemic inflammatory response to major trauma is necessary to refine treatment and to apply it optimally to all patients.

Abstract
The last century has seen great strides in the care of the polytrauma patient. Prior to the 1950s, routine operative stabilization of long bone fractures was not performed. With the advent of modern methods of fracture fixation the philosophy of early total care arrived and all fractures were operatively fixed at an early stage. Further understanding of the inflammatory response in trauma has now led to the concept of damage control orthopaedics. The aim of this review is to highlight this philosophy and its use in the polytrauma patient.

Abstract
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.

Abstract
BACKGROUND The purpose of the present paper was to study the effects of a femoral shaft fracture and its early stabilization on the morbidity, mortality, and outcome of multiple-injury patients with combined blunt head and chest trauma. The clinical course of patients was analysed using a prospectively gathered data base. METHODS Out of 352 multitrauma patients, from September 1992 to June 2000, we identified 28 patients with combined blunt chest and head trauma (abbreviated injury scale >/= 2) and a femoral fracture as the study group. A total of 120 patients with combined chest and head trauma but without femoral fracture formed the control group. Parameters examined included injury severity, injury pattern, haemodynamics at admission, mortality, duration of ventilation, length of stay in intensive care unit, and outcome. RESULTS There were no significant differences regarding the demographics and injury severity (injury severity score) between the two groups. No significant differences were found in terms of mortality, duration of ventilation\intensive care unit stay and outcome. Injury severity (P < 0.0001), age (P = 0.0153), and haemodynamics at admission (P = 0.0036) were shown to have a significant effect on mortality and outcome. Injury severity (P < 0.0001) and age (P = 0.017) had a significant effect on the duration of ventilation\intensive care unit stay. CONCLUSIONS The present study suggests that a femoral shaft fracture and its early stabilization in a multitrauma patient with combined chest and head injury do not adversely affect mortality and outcome and supports aggressive surgical management for these patients.

Abstract
Information illustrating the benefits of fracture stabilization after multiple trauma has been gathering for almost a century. At the turn of the last century, the introduction of the Thomas splint clearly demonstrated the importance of skeletal stabilization in the management of these patients. The introduction of standardized surgical treatment for fractures in the early 1950s is considered today as the turning point in the care of the polytraumatized patient. With the knowledge acquired, the application of early operative fixation of fractures in severely injured patients in the 1980s has yielded to the concept of early total care of all fractures. Yet, in distinct patient subgroups with severe thoracic injuries and very high injury severity scores, this concept has been associated with adverse outcomes. Therefore, in a further era that began in the 1990s, a different approach has been favored for these subgroups. It recommends early (initial) temporary stabilization followed by secondary definitive osteosynthesis of major fractures in patients at high risk of developing systemic complications. In the last decade, attempts have been made to determine which patients benefit from early total care and which ones should undergo a secondary definitive approach. This manuscript provides a historical overview on the changing treatment of fractures and summarizes the evolution of "damage control orthopedic surgery."

Abstract
BACKGROUND Optimal timing of femur fracture fixation remains controversial. This study examines the association between the timing of femur fracture fixation and outcome in patients with concomitant chest and head injuries. METHODS A retrospective review of registry data from a Level I trauma center identified 1362 patients with a femoral shaft fracture over a 12-year period. Patients were categorized into five groups by timing of femur fracture fixation: Group 1, within 24 hours; Group 2, 24 to 48 hours; Group 3, 48 to 120 hours; Group 4, > 120 hours; and Group 5, patients with no operative fixation. Primary outcome measures included morbidity (specifically, pulmonary complications) and mortality. Secondary outcome measures were hospital length of stay, intensive care unit length of stay, and discharge Glasgow Coma Scale score. Subsets of patients were examined including all patients with multiple injuries (Injury Severity Score > 15), chest trauma (Chest Abbreviated Injury Scale score > or = 2), and head trauma (Head Abbreviated Injury Scale score > or = 2). RESULTS Acute respiratory distress syndrome, pneumonia, hospital length of stay, and intensive care unit length of stay were lowest in the group fixed within 24 hours, even in patients with concomitant head or chest trauma. Fixation between 2 and 5 days was associated with a significantly increased incidence of acute respiratory distress syndrome, pneumonia, and fat embolization syndrome in patients with concurrent chest trauma (p < 0.0001). In head-injured patients, discharge Glasgow Coma Scale score was highest in the group fixed within 24 hours. Timing of operative fixation did not affect mortality. CONCLUSION Our data show that early femur fracture fixation (< 24 hours) is associated with an improved outcome, even in patients with coexistent head and/or chest trauma. Fixation of femur fractures at 2 to 5 days was associated with a significant increase in pulmonary complications, particularly with concomitant head or chest trauma, and length of stay. Chest and head trauma are not contraindications to early fixation with reamed intramedullary nailing.

Abstract
BACKGROUND This study was undertaken to determine whether alveolar dead space increases during intramedullary nailing of femoral shaft fractures and whether alveolar dead space predicts postoperative pulmonary dysfunction in patients undergoing intramedullary nailing of a femoral shaft fracture. METHODS All patients with a femoral shaft fracture were prospectively enrolled in the study unless there was evidence of acute myocardial infarction, shock, or heart failure. Arterial blood gases were measured at three consecutive time-periods after induction of general anesthesia: before intramedullary nailing and ten and thirty minutes after intramedullary nailing. The end-tidal carbon-dioxide level, minute ventilation, positive end-expiratory pressure, and percent of inspired and expired inhalation agent were recorded simultaneously with the blood-gas measurement. Postoperatively, all subjects were monitored for evidence of pulmonary dysfunction, defined as the need for mechanical ventilation or supplemental oxygen (at a fraction of inspired oxygen of >40%) in the presence of clinical signs of a respiratory rate of >20 breaths/min or the use of accessory muscles of respiration. RESULTS Seventy-four patients with a total of eighty femoral shaft fractures completed the study. Fifty fractures (62.5%) underwent nailing after reaming, and thirty fractures (37.5%) underwent nailing with minimal or no reaming. The mean alveolar dead-space measurements before canal opening and at ten and thirty minutes after canal opening were 14.5%, 15.8%, and 15.2% in the total series of seventy-four patients (general linear model, p = 0.2) and 20.5%, 22.7%, and 24.2% in the twenty patients with postoperative pulmonary dysfunction (general linear model, p = 0.05). Of the twenty-one patients with an alveolar dead-space measurement of >20% thirty minutes after nailing, sixteen had postoperative pulmonary dysfunction. According to univariate and multivariate analysis, the alveolar dead-space measurement was strongly associated with postoperative pulmonary dysfunction. CONCLUSIONS According to our data, intramedullary nailing of femoral shaft fractures did not significantly increase alveolar dead space, and the amount of alveolar dead space can predict which patients will have pulmonary dysfunction postoperatively.

Abstract
BACKGROUND Current techniques for assessment of chest trauma rely on clinical diagnoses or scoring systems. However, there is no generally accepted standard for early judgement of the severity of these injuries, especially in regards to related complications. This drawback may have a significant impact on the management of skeletal injuries, which are frequently associated with chest trauma. However, no convincing conclusions can be determined until standardization of the degrees of chest trauma is achieved. We investigated the role of early clinical and radiologic assessment techniques on outcome in patients with blunt multiple trauma and thoracic injuries and developed a new scoring system for early evaluation of chest trauma. METHODS A retrospective investigation was performed on the basis of 4,571 blunt polytrauma (Injury Severity Score [ISS] > or = 18) patients admitted to our unit. Inclusion criteria were treatment of thoracic injury that required intensive care therapy, initial Glasgow Coma Scale score greater than 8 points, and no local or systemic infection. Patients with thoracic trauma and multiple associated injuries (ISS > or = 18) were included. In all patients, the association between various parameters of the thoracic injuries and subsequent mortality and morbidity was investigated. RESULTS A total of 1,495 patients fulfilled the inclusion criteria. Patients' medical records and chest radiographs were reevaluated between May 1, 1998, and June 1, 1999. The association between rib fractures and chest-related death was low (> three ribs unilateral, mortality 17.3%, odds ratio 1.01) unless bilateral involvement was present (> three ribs bilateral, mortality 40.9%, odds ratio 3.43). Injuries to the lung parenchyma, as determined by plain radiography, were associated with chest-related death, especially if the injuries were bilateral or associated with hemopneumothorax (lung contusion unilateral, mortality 25.2%, odds ratio 1.82; lung contusion bilateral + hemopneumothorax, mortality 53.3%, odds ratio 5.1). When plain anteroposterior chest radiographs were used, the diagnostic rate of rib fractures (< or = three ribs) increased slightly, from 77.1% to 97.3% during the first 24 hours of admission. In contrast, pulmonary contusions were often not diagnosed until 24 hours after admission (47.3% at admission, 92.4% at 24 h, p = 0.002). A new composite scoring system (thoracic trauma severity score) was developed that combines several variables: injuries to the chest wall, intrathoracic lesions, injuries involving the pleura, admission PaO2/FIO2 ratio, and patient age. The receiver operating characteristic curve demonstrated an adequate discrimination, as demonstrated by a value of 0.924 for the development set and 0.916 for the validation set. The score was also superior to the ISS (0.881) or the thorax Abbreviated Injury Score (0.693). CONCLUSION Radiographically determined injuries to the lung parenchyma have a closer association with adverse outcome than chest-wall injuries but are often not diagnosed until 24 hours after injury. Therefore, clinical decision making, such as about the choice of surgery for long bone fractures, may be flawed if this information is used alone. A new thoracic trauma severity score may serve as an additional tool to improve the accuracy of the prediction of thoracic trauma-related complications.

Abstract
All intramedullary nailing creates some loss of endosteal blood supply and an increase in intramedullary pressure, resulting in marrow embolization. In laboratory studies, both reamed and nonreamed intramedullary nailing have led to alteration in selected pulmonary variables. This effect, although transient, appeared more pronounced with reamed techniques than with nonreamed techniques. Concern about the systemic pulmonary effects of reamed intramedullary nailing has led to an increase in the use of nonreamed nailing. The authors of most clinical studies have reported that reamed intramedullary nailing has not been associated with a concomitant increase in pulmonary complications in multiply injured patients, although this point is still controversial. Femoral shaft fractures treated with nonreamed nailing have been shown to have slightly higher rates of delayed union and nonunion compared with those treated with reamed nails. Reamed interlocking intramedullary fixation remains the treatment of choice for femoral shaft fractures in adults. Further study is required to determine whether an identifiable subgroup of trauma patients is adversely affected by intramedullary reaming, which would suggest the need for alternative fixation techniques.

Abstract
BACKGROUND This study was undertaken to determine if the alveolar dead space fraction (Vd/Vt) or the alveolar-arterial oxygen gradient (A-a DO2) increased during intramedullary fixation of femoral shaft fractures. METHODS Fifty hemodynamically stable patients with femur fractures were prospectively enrolled. Three serial measurements of Vd/Vt and A-a DO2 were obtained immediately before femoral nailing (Pre), 30 minutes after nailing (+30), and 120 minutes after nailing (+120). Vd/Vt was determined by simultaneously measuring PaCO2 and the steady-state end-tidal CO2 (PetCO2), where Vd/Vt = (1 - PetCO2/PaCO2). RESULTS Vd/Vt before nailing was 0.09 +/- 0.09 (mean +/- SD); at +30 and +120, Vd/Vt was 0.10 +/- 0.06 and 0.08 +/- 0.07, respectively (p > 0.2; paired t test, both time points). A-a DO2 before nailing was 84 +/- 85 mm Hg, and it did not change significantly at +30 (89 +/- 69 mm Hg; p = 0.51 vs. Pre; paired t-test) or at +120 (51 +/- 45 mm Hg). No difference in data was found with analysis by fracture classification or number of reamer passes. Vd/Vt and A-a DO2, however, were both significantly increased in patients with lung contusion (n = 6) before nailing, but neither measurement increased after nailing. One patient developed fat embolism (Vd/Vt of 0.35 at Pre and 0.31 at +120), and another patient experienced postoperative pulmonary thromboembolism (Vd/Vt increased from 0.06 at Pre to 0.17 at +120). CONCLUSION The process of femoral nailing does not cause enough pulmonary embolization to alter pulmonary gas exchange as measured by Vd/Vt and A-a DO2. If Vd/Vt is increased preoperatively, the likelihood of subsequent pulmonary dysfunction secondary to either preoperative lung injury or fat embolism is increased.
