Abstract
OBJECTIVE In his original series of 129 surgically treated acetabular fractures, Letournel did not operate on patients older than 60 years. Almost 30 years later, he still emphasized that no patients with reduced bone quality should be operated on. The aim of the study was to analyze epidemiologic characteristics and treatment modes for today's cohort of elderly patients with acetabular fractures. DESIGN Retrospective analysis. SETTING Multicenter registry/Level I trauma center. PATIENTS Three thousand seven hundred ninety-three patients who had sustained a fracture of the acetabulum. INTERVENTION Operative and nonoperative treatment of acetabular fractures. MAIN OUTCOME MEASUREMENTS Epidemiologic characteristics, treatment mode, in-hospital mortality, rate of secondary hip arthroplasty, and quality of life indicated by EQ-5D score. RESULTS For the multicenter registry, more than 50% of all patients with acetabular fractures had an age of 60 years or over. The age peak was found at 75-80 years. Fifty percent of the elderly patients were treated surgically. The in-hospital mortality was significantly higher in elderly patients than patients younger than 60 years. In our Level I trauma center, surgical treatment by open reduction and internal fixation did not influence in-hospital mortality or quality of life of elderly patients with acetabular fractures. CONCLUSIONS Today, elderly persons represent the dominant cohort among patients with fractures of the acetabulum. Fifty-five years after the publication of Letournel's original case series, data indicate that currently, surgical treatment is a common and necessary option in the therapy of acetabular fractures in elderly patients. LEVEL OF EVIDENCE Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Pelvic fractures in the Netherlands: epidemiology, characteristics and risk factors for in-hospital mortality in the older and younger population. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2017; 28:197-205. [PMID: 28993913 DOI: 10.1007/s00590-017-2044-3] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/26/2017] [Accepted: 09/24/2017] [Indexed: 01/24/2023]
Abstract
PURPOSE To examine nationwide epidemiology of pelvic fractures in the Netherlands and to compare characteristics and outcome of older versus younger patients as well as predictors for in-hospital mortality. METHODS Retrospective review of pelvic fracture patients admitted to all Dutch hospitals (2008-2012) utilizing National Trauma Registry. Average annual incidence of (minor and major) pelvic fractures was calculated for the population. Older (≥ 65 years) and younger (< 65 years) patients were compared. Multivariate regression analysis was performed to identify independent predictors for in-hospital mortality. RESULTS Of 11,879 pelvic fracture patients (61.8%, ≥ 65 years), annual incidence of pelvic fractures in older versus younger population was 57.9 versus 6.4 per 100,000 persons. Older patients had lower ISS (7.1 (SD 6.9) vs 15.4 (SD 13.4)) and less frequently had severe associated injuries (15.6 vs 43.5%), an admission systolic blood pressure (SBP) ≤ 90 mmHg (1.6 vs 4.1%) or Glasgow Coma Score (GCS) ≤ 12 (2.0 vs 13.3%) (all, p < 0.01). In-hospital mortality was equal in older and younger patients (5.3 vs 4.8%: p = 0.28). In both subgroups, greatest independent predictors for in-hospital mortality were GCS ≤ 12, ISS ≥ 16, and SBP ≤ 90 mmHg and in all patients age ≥ 65 (OR 6.59 (5.12-8.48): p < 0.01). CONCLUSION The annual incidence of (both minor and major) pelvic fractures in the older population was substantially higher than in the younger population. Elderly patients had a disproportionately high in-hospital mortality rate considering they were less severely injured. Among other factors, age was the greatest independent predictor for in-hospital mortality in all pelvic fracture patients.

Abstract
As pelvic fractures in children and adolescents are very rare, the surgical management is not well delineated nor are the postoperative complications. The aim of this study using the prospective data from German Pelvic Trauma Registry study was to evaluate the various treatment approaches compared to adults and delineated the differences in postoperative complications after pelvic injuries.Using the prospective pelvic trauma registry established by the German Society of Traumatology and the German Section of the Arbeitsgemeinschaft für Osteosynthesefragen (AO), International in 1991, patients with pelvic fractures over a 12-year time frame submitted by any 1 of the 23 member level I trauma centers were reviewed.We identified a total of 13,525 patients including pelvic fractures in 13,317 adults and 208 children aged ≤14 years and compared these 2 groups. The 2 groups' Injury Severitiy Score (ISS) did not differ statistically. Lethality in the pediatric group was 6.3%, not statistically different from the adults' 4.6%. In all, 18.3% of the pediatric pelvic fractures were treated surgically as compared to 22.7% in the adult group. No child suffered any thrombosis/embolism, acute respiratory distress syndrome (ARDS), multiorgan failure (MOF), or neurologic deficit, nor was any septic MOF detected. The differences between adults and children were statistically significant in that the children suffered less frequently from thrombosis/embolism (P = 0.041) and ARDS and MOF (P = 0.006).This prospective multicenter study addressing patients with pelvic fractures reveals that the risk for a thrombosis/embolism, ARDS, and MOF is significant lower in pediatric patients than in adults. No statistical differences could be found in the ratios of operative therapy of the pelvic fractures in children compared to adults.

Abstract
STUDY OBJECTIVE To document mortality rate and predictors of mortality in elderly patients with complex pelvic fractures. METHODS We reviewed a total of 84 subjects whose ages were above 70 years with complex pelvic fractures, admitted to our hospital from January 2001 to December 2012. A multivariate linear regression model was used to determine the predictors of mortality in the study population. The median age of the patients was 80.4 years (range 70-94 years). 65 of 84 (77%) patients were females. There were 72 Tile Type B fractures (86%) and 12 Type C fractures (14%). The most common associated injuries were thoracic, extremity and head injuries, with incidence of 13 (15%), 11 (13%), and 9 (11%), respectively. RESULTS The mortality rate was 10% in our study population. The initial haemoglobin on admission (p<0.01), the presence of blood vessel injuries (p<0.01) and the number of PRBCs transfused within the first six hours after admission (p<0.01) independently predicted mortality in elderly patients with complex pelvic fractures. CONCLUSION Although there is a downward trend in mortality in elderly patients with complex pelvic fractures, haemodynamic instability still has a significant impact on survival of those patients.

Intra- and postoperative complications of navigated and conventional techniques in percutaneous iliosacral screw fixation after pelvic fractures: Results from the German Pelvic Trauma Registry. Injury 2013; 44:1765-72. [PMID: 24001785 DOI: 10.1016/j.injury.2013.08.008] [Citation(s) in RCA: 39] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2013] [Revised: 06/03/2013] [Accepted: 08/07/2013] [Indexed: 02/02/2023]
Abstract
BACKGROUND Percutaneous iliosacral screw placement following pelvic trauma is a very demanding technique involving a high rate of screw malpositions possibly associated with the risk of neurological damage or inadequate stability. In the conventional technique, the screw's correct entry point and the small target corridor for the iliosacral screw may be difficult to visualise using an image intensifier. 2D and 3D navigation techniques may therefore be helpful tools. The aim of this multicentre study was to evaluate the intra- and postoperative complications after percutaneous screw implantation by classifying the fractures using data from a prospective pelvic trauma registry. The a priori hypothesis was that the navigation techniques have lower rates of intraoperative and postoperative complications. METHODS This study is based on data from the prospective pelvic trauma registry introduced by the German Society of Traumatology and the German Section of the AO/ASIF International in 1991. The registry provides data on all patients with pelvic fractures treated between July 2008 and June 2011 at any one of the 23 Level I trauma centres contributing to the registry. RESULTS A total of 2615 patients were identified. Out of these a further analysis was performed in 597 patients suffering injuries of the SI joint (187×with surgical interventions) and 597 patients with sacral fractures (334×with surgical interventions). The rate of intraoperative complications was not significantly different, with 10/114 patients undergoing navigated techniques (8.8%) and 14/239 patients in the conventional group (5.9%) for percutaneous screw implantation (p=0.4242). Postoperative complications were analysed in 30/114 patients in the navigated group (26.3%) and in 70/239 patients (29.3%) in the conventional group (p=0.6542). Patients who underwent no surgery had with 66/197 cases (33.5%) a relatively high rate of complications during their hospital stay. The rate of surgically-treated fractures was higher in the group with more unstable Type-C fractures, but the fracture classification had no significant influence on the rate of complications. DISCUSSION In this prospective multicentre study, the 2D/3D navigation techniques revealed similar results for the rate of intraoperative and postoperative complications compared to the conventional technique. The rate of neurological complications was significantly higher in the navigated group.

Abstract
BACKGROUND Emergency devices for pelvic ring stabilization include circumferential sheets, pelvic binders, and c-clamps. Our knowledge of the outcome of these techniques is currently based on limited information. METHODS Using the dataset of the German Pelvic Trauma Registry, demographic and injury-associated characteristics as well as the outcome of pelvic fracture patients after sheet, binder, and c-clamp treatment was compared. Outcome parameters included transfusion requirement of packed red blood cells, length of hospital stay, mortality, and incidence of lethal pelvic bleeding. RESULTS Two hundred seven of 6137 (3.4%) patients documented in the German Pelvic Trauma Registry between April 30th 2004 and January 19th 2012 were treated by sheets, binders, or c-clamps. In most cases, c-clamps (69%) were used, followed by sheets (16%), and binders (15%). The median age was significantly lower in patients treated with binders than in patients treated with sheets or c-clamps (26 vs. 47 vs. 42 years, p=0.01). Sheet wrapping was associated with a significantly higher incidence of lethal pelvic bleeding compared to binder or c-clamp stabilization (23% vs. 4% vs. 8%). No significant differences between the study groups were found in sex, fracture type, blood haemoglobin concentration, arterial blood pressure, Injury Severity Score, the incidence of additional pelvic packing and arterial embolization, need of red blood cell transfusion, length of hospitalisation, and mortality. CONCLUSIONS The data suggest that emergency stabilization of the pelvic ring by binders and c-clamps is associated with a lower incidence of lethal pelvic bleeding compared to sheet wrapping.

Abstract
BACKGROUND Data from literature on predictors for patients' quality of life after pelvic ring fractures are conflicting and based on small study populations. QUESTIONS/PURPOSES We therefore evaluated predictors for health-related quality of life in patients with pelvic ring injuries at a minimum of 1 year postfracture. METHODS We surveyed 172 patients of the German Pelvic Trauma Registry admitted to four medical centers between February 3, 2004, and May 11, 2011. The median age of the followup cohort was 47 years (range, 8-88 years); 69 of 172 (40%) patients were female. Patients were characterized by a median Injury Severity Score of 17. There were 31 Tile Type A fractures (18%), 77 Type B fractures (45%), and 64 Type C fractures (37%). The incidence of complex fractures and multiple traumas was 34 of 172 (20%) and 116 of 172 (67%), respectively. One hundred twenty-five (73%) patients were treated operatively. We obtained the EQ-5D™ score to assess patients' health-related quality of life. For the analysis of predictors for quality of life, a multivariate linear regression model was built. The median followup was 3 years (range, 1-6 years). RESULTS The median EQ-5D™ score was 0.78 (interquartile limits, 0.63 and 1.00). Age, complex trauma, and surgery independently predicted the EQ-5D™ score. CONCLUSIONS We conclude patients with higher age, complex trauma, and surgery had a higher likelihood for a reduced quality of life after pelvic ring injuries.

Abstract
BACKGROUND Our knowledge of factors influencing mortality of patients with pelvic ring injuries and the impact of associated injuries is currently based on limited information. QUESTIONS/PURPOSES We identified the (1) causes and time of death, (2) demography, and (3) pattern and severity of injuries in patients with pelvic ring fractures who did not survive. METHODS We prospectively collected data on 5340 patients listed in the German Pelvic Trauma Registry between April 30, 2004 and July 29, 2011; 3034 of 5340 (57%) patients were female. Demographic data and parameters indicating the type and severity of injury were recorded for patients who died in hospital (nonsurvivors) and compared with data of patients who survived (survivors). The median followup was 13 days (range, 0-1117 days). RESULTS A total of 238 (4%) patients died a median of 2 days after trauma. The main cause of death was massive bleeding (34%), predominantly from the pelvic region (62% of all patients who died because of massive bleeding). Fifty-six percent of nonsurvivors and 43% of survivors were male. Nonsurvivors were characterized by a higher incidence of complex pelvic injuries (32% versus 8%), less isolated pelvic ring fractures (13% versus 49%), lower initial blood hemoglobin concentration (6.7 ± 2.9 versus 9.8 ± 3.0 g/dL) and systolic arterial blood pressure (77 ± 27 versus 106 ± 24 mmHg), and higher injury severity score (ISS) (35 ± 16 versus 15 ± 12). CONCLUSION Patients with pelvic fractures who did not survive were characterized by male gender, severe multiple trauma, and major hemorrhage. LEVEL OF EVIDENCE Level III, prognostic study.

Abstract
STUDY OBJECTIVE To determine longitudinal trends in mortality, and the contribution of specific injury characteristics and treatment modalities to the risk of a fatal outcome after severe and complex pelvic trauma. METHODS We studied 5048 patients with pelvic ring fractures enrolled in the German Pelvic Trauma Registry Initiative between 1991 and 1993, 1998 and 2000, and 2004 and 2006. Complete datasets were available for 5014 cases, including 508 complex injuries, defined as unstable fractures with severe peri-pelvic soft tissue and organ laceration. Multivariable mixed-effects logistic regression analysis was employed to evaluate the impact of demographic, injury- and treatment-associated variables on all-cause in-hospital mortality. RESULTS All-cause in-hospital mortality declined from 8% (39/466) in 1991 to 5% (33/638) in 2006. Controlling for age, Injury Severity Score, pelvic vessel injury, the need for emergency laparotomy, and application of a pelvic clamp, the odds ratio (OR) per annum was 0.94 (95% confidence interval [CI] 0.91-0.96). However, the risk of death did not decrease significantly in patients with complex injuries (OR 0.98, 95% CI 0.93-1.03). Raw mortality associated with this type of injury was 18% (95% CI 9-32%) in 2006. CONCLUSION In contrast to an overall decline in trauma mortality, complex pelvic ring injuries remain associated with a significant risk of death. Awareness of this potentially life-threatening condition should be increased amongst trauma care professionals, and early management protocols need to be implemented to improve the survival prognosis.

Abstract
OBJECTIVE To examine the organizational, political, and community characteristics that facilitate or impede community progress in developing a coordinative network of health services for trauma delivery. STUDY SETTING/DESIGN: A comparative case study design was used to examine trauma network development in 6 U.S. cities with a population of 1,000,000 or more. Five key coordinative activities were selected for study. Each study site varied in the set of activities that had been implemented. DATA SOURCES Information on the structure and composition of local trauma coordinating councils; interviews with a common set of informants in each site using a semi-structured interview protocol. STUDY METHODS The literature on interorganizational community structures and local policy development was drawn upon to create a conceptual framework for assessing the development of a coordinative service network. Analytical techniques included network analysis to understand the linkages across organizations in overseeing trauma network operations, assessment of leadership structures to identify central actors and organizations, and pattern matching techniques of case study analysis to identify factors that affected trauma network development. PRINCIPAL FINDINGS Leaders capitalized on local events and were instrumental in keeping network development on the top of the political agenda. Successful leaders spent substantial time and energy documenting problems, assessing the needs and understanding of stakeholders, educating stakeholders and politicians, and creating trust and shared understanding of values. CONCLUSIONS Prior research has documented the importance of central actors and organizations in developing coordinative networks. The unique contribution of our research is its insights on how central actors and organizations are more likely to motivate collaboration in situations where they lack control over the allocation of payments across involved organizations. Our research suggests that under these circumstances central players should focus their time and energy educating stakeholders and developing a shared understanding rather than using their centrality to impose a particular coordinative structure. To date, U.S. trauma networks have served as models for other industrialized countries, and thus, lessons learned in the U.S. about implementing interorganizational networks of trauma care can assist other countries achieve more effective coordination and avoid mistakes that impede progress.

Abstract
BACKGROUND Unlike previous studies in an urban environment, this study examines traumatic death in a geographically diverse county in the southwestern United States. METHODS All deaths from blunt and penetrating trauma between November 15, 1991, and November 14, 1993, were included. As many as 150 variables were collected on each patient, including time of injury and time of death. Initial identification of cases was through manual review of death records. Information was supplemented by review of hospital records, case reports, and prehospital encounter forms. RESULTS A total of 710 traumatic deaths were analyzed. Approximately half of the victims, 52%, were pronounced dead at the scene. Of the 48% who were hospitalized, the most frequent mechanism of injury was a fall. Neurologic dysfunction was the most common cause of death. Two distinct peaks of time were found on analysis: 23% of patients died within the first 60 minutes, and 35% of patients died at 24 to 48 hours after injury. CONCLUSIONS Although there appears to continue to be a trimodal distribution of trauma deaths in urban environments, we found the distribution to be bimodal in an environment with a higher ratio of blunt to penetrating trauma.

Abstract
OBJECTIVES To identify all hospitals in the United States that operated a trauma center between 1980 and 1991 and to contrast their organizational, service, and medical staff characteristics. DESIGN Trauma centers were identified through a series of surveys and follow-up discussions with state emergency medical service directors. Data on hospital characteristics were obtained through the American Hospital Association's 1990 Annual Survey of Hospitals. MATERIALS AND METHODS Hospital characteristics were compared across: (1) hospitals with and without trauma centers; (2) operational and closed trauma centers; and (3) trauma centers-based on trauma level and source of designation. MEASUREMENTS AND MAIN RESULTS Overall, 471 operational trauma centers and 58 hospitals that dropped this service were identified. Several differences were found in hospital operational, service, and medical staff characteristics across hospitals with and without trauma centers and across trauma centers distinguished by trauma level and by whether they continued to provide the service through 1991. Few differences were present across formally designated and self-designated centers. CONCLUSIONS The study provides structural and organizational profiles of trauma centers that should help trauma system planners identify strong candidates for trauma center designation.

Abstract
OBJECTIVE This study used population-based data bases to assess the association of trauma centers with per capita county hospitalization and trauma death rates in the State of North Carolina. SUMMARY BACKGROUND DATA The current study extended previous work using two North Carolina data bases to assess the association of the presence of a trauma center with per capita county trauma death rates. METHODS Data on per capita county trauma hospitalizations and deaths were obtained from the state hospital discharge data base and the North Carolina Medical Examiner's data base. Bivariate and multivariate analysis techniques were used. The dependent variables of interest were prehospital, hospital, and total trauma death rates and hospitalization rates for injury. RESULTS Bivariate analysis identified a number of factors associated with per capita county hospitalizations and trauma death rates. These included the per cent unemployment, racial distribution, county alcohol tax receipts, and advanced life support certified emergency medical services providers. The per capita trauma death rates were significantly lower in counties with trauma centers compared with those without trauma centers (4.0 +/- 0.5 and 5.0 +/- 1.1 deaths per 10,000 population, p = 0.0001, respectively). The per capita hospitalizations for trauma were also lower in counties with trauma centers. Multivariate modeling showed that the presence of a trauma center and advanced life support providers were the best predictors of decreased per capita county trauma death rates. CONCLUSIONS The study showed that the presence of a trauma center and advanced life support training were the two medical system factors that were the best predictors of the per capita county prehospital and total trauma death rates. These findings are consistent with the hypothesis that trauma centers are associated with a decrease in trauma death rates.

Abstract
STUDY OBJECTIVE To develop a new trauma decision rule. DESIGN Retrospective clinical review. SETTING Level I trauma center. TYPE OF PARTICIPANTS 1,004 injured adults. MEASUREMENTS AND MAIN RESULTS A new trauma decision rule was derived from 1,004 injured adult patients using a new operational definition of major trauma. The rule, termed the Trauma Triage Rule, defines a major trauma victim as any injured adult patient whose systolic blood pressure is less than 85 mm Hg; whose motor component of the Glasgow Coma Score is less than 5; or who has sustained penetrating trauma of the head, neck, or trunk. Using the operational definition of major trauma, the rule had a sensitivity of 92% and a specificity of 92% when tested on the 1,004-patient cohort. CONCLUSION The Trauma Triage Rule may significantly reduce overtriage while only minimally increasing undertriage. This approach must be validated prospectively before it can be used in the prehospital setting.

Abstract
National estimates of the numbers and expenditures associated with hospitalization due to injury among children (aged 0 to 14) were derived using data from the 1984, 1985, and 1986 National Hospital Discharge Surveys (NHDS) and the 1980 National Medical Care Utilization and Expenditures Study (NMCUES). In this report, age- and sex-specific estimates of the numbers of hospital admissions and expenditures are reported for subgroup of patients defined by external cause of the injury and by nature and severity of the injury. In 1985, over 266,000 children sustained a traumatic injury resulting in hospitalization (rate of 51 per 10,000 children). Expenditures totaled nearly $1 billion. Over 80% of the hospitalizations and two thirds of total expenditures were for minor (Maximum AIS = 1.2) trauma. Moderate (Maximum AIS = 3) and severe (Maximum AIS = 4,5) trauma accounted for 18% and 2% of admissions and 31% and 8% of expenditures, respectively. Falls ranked first in expenditures and admissions (36% of the total). Motor vehicle-related injuries accounted for 19% of trauma admissions and 24% of expenditures. Other less common causes included bicycle injuries, penetrating injuries and injuries caused by the child being hit by an object or person. An estimated 28% of the total hospital charges were paid for by public sources (15% from federal government programs, 13% from state and local programs). An additional 63% of total expenditures were paid for by private sources, with the remaining 9% considered uninsured care.(ABSTRACT TRUNCATED AT 250 WORDS)
