Predictors of Acute Mortality After Open Pelvic Fracture: Experience From 37 Patients From A Level I Trauma Center.

BACKGROUND: Open pelvic fractures are caused by high-energy traumas and are accompanied by organ injuries. Despite improvements in pre-hospital care, the acute mortality rate following open pelvic fractures remains high. This study aimed to report experiences in managing open pelvic fractures, identify potential independent predictors that contribute to acute mortality in such patients, and generate a scoring formula to predict mortality rate. METHODS: Open pelvic fracture patients managed during a 42-month period were retrospectively studied. Logistic regression analysis was used to determine predictors of acute mortality. Using the Youden index, threshold values of predictors were selected. Significant predictors were weighted to create a scoring formula. The area under the curve (AUC) was tested in this specific group. RESULTS: The incidence of open pelvic fractures in all pelvic fractures was 4.9% (37/772), and the overall mortality rate was 21.6% (8/37). All the successfully resuscitated patients entered the reconstruction stage survived and underwent the complete treatment course. Univariate and multivariate logistic regression analyses revealed that the revised trauma score (RTS) was the single independent predictor of acute mortality. A scoring formula was generated following the statistical analysis. The probability of mortality was 0% and 100% when the score was above and below -2, respectively. This model predicted mortality with an AUC of 0.948 (95% confidence interval 0.881-1.000, P < 0.01). CONCLUSION: The RTS may be a potential predictor of acute mortality in open pelvic fracture patients. Further work would be required to validate the clinical efficacy of the generated scoring formula.

Clinical features and risk factors for mortality in patients with open pelvic fracture: A retrospective study of 46 cases.

BACKGROUND: This study aimed to investigate the clinical features, current management strategies, and outcomes of open pelvic fracture patients. METHODS: We performed a retrospective review of data on patients with blunt trauma and open pelvic fractures admitted to our trauma center over a 5-year period (January 2013 to December 2017). Demographic as well as clinical data including injury mechanism, injury severity score (ISS), fracture classifications, transfusion requirements, interventions, length of hospital and intensive care unit (ICU) stay, and prognosis were investigated. Univariate analysis and binary logistic regression were used to identify the risk variables of death. Finally, a brief literature review was performed to understand the current capacity of treatment and prognosis of this type of injury. RESULTS: Forty-six patients (36 male and 10 female) were included in this study, mean age 43.2 ± 14.2 years. The overall mortality rate was 17.4%; 43.5% of the patients were hypotensive (systolic blood pressure (SBP) <90 mmHg) on arrival. The average ISS was 31.7 ± 6.7, and the average packed red blood cell (PRBC) transfusion during the first 24 h was 9.6 ± 7.4 units. Five patients (10.9%) underwent transcatheter arterial embolization in the early stage of management. The average hospital and ICU length of stay were 53.0 ± 37.6 days and 14.3 ± 15.3 days, respectively. Statistically significant differences were found in ISS, PRBC units received with the first 24 h, SBP, lactate and base excess on admission, and mechanism of injury when comparing between the death and the survival groups (p < 0.05). ISS and lactate on admission were found to be the independent risk factors for mortality. CONCLUSION: The mortality rate of open pelvic fractures remains high. ISS and lactate on admission were the independent risk factors for mortality. Optimization of the trauma care algorithms for early identification and treatment of this injury could be the key to decreasing mortality.

Preperitoneal pelvic packing is effective for hemorrhage control in open pelvic fractures.

BACKGROUND: Open pelvic fractures are life-threatening injuries. Preperitoneal pelvic packing (PPP) has been suggested to be ineffective for hemorrhage control in open pelvic fractures. We hypothesize that PPP is effective at hemorrhage control in patients with open pelvic fractures and reduces mortality. METHODS: Patients undergoing PPP from 2005 to 2015 were analyzed. Patients with open pelvic fractures were defined as direct communication of the bony injury with overlying soft tissue, vagina, or rectum. RESULTS: During the 10-year study, 126 patients underwent PPP; 14 (11%) sustained an open pelvic fracture. After PPP, 1 patient (7%) underwent angioembolization with a documented arterial blush. PPP controlled pelvic hemorrhage in all patients. Overall mortality rate was 7% with one death due to traumatic brain injury. CONCLUSIONS: PPP is effective for hemorrhage control in patients with open pelvic fractures. PPP should be used in a standard protocol for hemodynamically unstable patients with pelvic fractures regardless of associated perineal injuries.

Combat-related acetabular fractures: Outcomes of open versus closed injuries.

INTRODUCTION: Since the onset of the Global War on Terror close to 50,000 United States service members have been injured in combat, many of these injuries would have previously been fatal. Among these injuries, open acetabular fractures are at an increased number due to the high percentage of penetrating injuries such as high velocity gunshot wounds and blast injuries. These injuries lead to a greater degree of contamination, and more severe associated injuries. There is a significantly smaller proportion of the classic blunt trauma mechanism typically seen in civilian trauma. METHODS: We performed a retrospective review of the Department of Defense Trauma Registry into which all US combat-injured patients are enrolled, as well as reviewed local patient medical records, and radiologic studies from March 2003 to April 2012. Eighty seven (87) acetabular fractures were identified with 32 classified as open fractures. Information regarding mechanism of injury, fracture pattern, transfusion requirements, Injury Severity Score (ISS), and presence of lower extremity amputations was analyzed. RESULTS: The mechanism of injury was an explosive device in 59% (n=19) of patients with an open acetabular fracture; the remaining 40% (n=13) were secondary to ballistic injury. In contrast, in the closed acetabular fracture cohort 38% (21/55) of fractures were due to explosive devices, and all remaining (n=34) were secondary to blunt trauma such as falls, motor vehicle collisions, or aircraft crashes. Patients with open acetabular fractures required a median of 17units of PRBC within the first 24h after injury. The mean ISS was 32 in the open group compared with 22 in the closed group (p=0.003). In the open fracture group nine patients (28%) sustained bilateral lower extremity amputations, and 10 patients (31%) ultimately underwent a hip disarticulation or hemi-pelvectomy as their final amputation level. DISCUSSION: Open acetabular fractures represent a significant challenge in the management of combat-related injuries. High ISS and massive transfusion requirements are common in these injuries. This is one of the largest series reported of open acetabular fractures. Open acetabular fractures require immediate damage control surgery and resuscitation as well as prolonged rehabilitation due to their severity. The dramatic number of open acetabular fractures (37%) in this review highlights the challenge in treatment of combat related acetabular fractures.

Factors of Pelvic Infection and Death in Patients with Open Pelvic Fractures and Rectal Injuries.

BACKGROUND: Open pelvic fractures associated with rectal injuries are uncommon. They often cause serious pelvic infection, even death. This combination of injuries has been reviewed infrequently. Herein, we report factors associated with pelvic infection and death in a group of patients with open pelvic fractures and concurrent rectal injuries. METHODS: We retrospectively reviewed the records of patients with open pelvic fractures and rectal injuries who were treated at our institution from January 2010-April 2014. From the medical records, age, gender, Injury Severity Score (ISS), cause of fracture, associated injuries, classification of the fracture, degree of soft-tissue injury, Glasgow Coma Score (GCS), Revised Trauma Score (RTS), packed red blood cells (PRBCs) needed, presence/absence of shock, early colostomy (yes or no), drainage (yes or no), and rectal washout (yes or no) were extracted. Univariable and multivariable analysis were performed to determine the association between risk factors and pelvic infection or death. RESULTS: Twenty patients were identified. Pelvic infection occurred in 50% (n = 10) of the patients. Four patients suffered septicemia, and three patients died of multiple organ dysfunction. The mortality rate thus was 15%. According to the univariable analysis, the patients in whom pelvic infection developed had shock, RTS ≤8, GCS ≤8, blood transfusion ≥10 units in the first 24 h, no colostomy, or Gustilo grade III soft-tissue injury. According to the multivariable analysis, shock and absence of colostomy were independently associated with pelvic infection. By univariable analysis, the only factor associated with death was RTS ≤8. CONCLUSION: The incidence of pelvic infection was lower in patients having early colostomy (p < 0.05). Patients with shock had a higher risk of pelvic infection, and we recommend aggressive measures to treat these patients. According to our results, RTS ≤8 could be a predictor of poor outcomes in patients with open pelvic fracture and concurrent rectal injury. Open reduction and internal fixation after extensive debridement is recommended in patients with unstable pelvic fractures.

Classification of soft-tissue injuries in open femur fractures: Relevant for systemic complications?

BACKGROUND: A broad range of systemic complications has been described to occur in patients with open major fractures. Various causes have been claimed to play a role. We therefore surveyed a nationwide trauma registry to assess risk factors associated with closed and various types of open femur fractures. METHODS: This was a cohort study in a nationwide population-based prospective database. Inclusion criteria for selection from database are as follows: individuals with femur fracture, age 16 years or older, and survival until primary admission. Main groups included closed and open femur fracture. Patient demographics, injury severity (New Injury Severity Score), surgical fracture management, length of stay, and systemic complications (e.g., multiple organ failure [MOF], sepsis, mortality) were collected and statistically analyzed using SPSS statistics. Multivariate regression analysis was performed to stratify subgroups for the degree of open soft-tissue injury according to Gustilo and Anderson. RESULTS: Among 32,582 documented trauma victims (January 1, 2002, to December 31, 2010), a total of 5,761 met the inclusion criteria. Main groups: 4,423 closed (76.8%) and 1,338 open femur fractures (23.2%). Open fractures subgroups were divided into I° (334, 28.1%), II° (526, 44.3%), and III° (328, 27.6%). Open fractures were associated with an increased risk of prehospital hemorrhagic shock (p = 0.01), higher resuscitation requirements (p < 0.001), MOF (p = 0.001), and longer in-hospital (p < 0.001) and intensive care stay (p = 0.001). While New Injury Severity Score values showed a minor increase per subgroup, the prevalence of MOF, sepsis, and mortality multiplied with the degree of open soft-tissue injury. Especially patients with Type III open femur fractures received mass transfusions (28.2%, p < 0.001), and mass transfusions were identified as independent predictor for sepsis (odds ratio [OR], 2.393; 95% confidence interval [CI], 1.821-3.143; p < 0.001) and MOF (OR, 2.966; 95% CI, 2.409-3.651; p < 0.001). Our data also indicate an increased mortality in patients with open femur managed outside Level I trauma centers (OR, 1.358; 95% CI, 1.018-1.812; p = 0.037). CONCLUSION: Open femur fractures are associated with higher in-hospital complications related to incidence of MOF, associated intensive care unit stay, and hospital days when compared with closed femur fractures. For prevention of in-hospital complications, prompt hemorrhage control, surgical fracture fixation, cautious blood management, and triage to a Level I trauma center must be considered. LEVEL OF EVIDENCE: Epidemiologic/prognostic study, level II.

Third degree open fractures and traumatic sub-/total amputations of the upper extremity: Outcome and relevance of the Mangled Extremity Severity Score.

INTRODUCTION: Third degree open fractures and traumatic sub-/total amputations of the upper extremity represent severe injuries and are associated with a high rate of functional impairment of the affected extremity. More than 20 years ago, the Mangled Extremity Severity Score (MESS) was introduced to predict amputation following severe lower extremity trauma. However, there have been few studies evaluating MESS in connection with the mangled upper limb. MATERIAL AND METHODS: A retrospective medical chart review was performed of all patients diagnosed with the aforementioned fractures of the upper extremity treated at the Department of trauma surgery (level I trauma center) and the Clinical division of plastic and reconstructive surgery at the general hospital of Vienna between 1994 and 2014. RESULTS: Fifty-four out of 606 patients (9%) suffered from a total of 61 third degree open fractures or traumatic sub-/total amputations of the upper extremity (Gustilo-Anderson, type IIIA, n=30; Gustilo-Anderson, type IIIB, n=15; Gustilo-Anderson, type IIIC, n=9; traumatic sub-/total amputations, n=7). Thirty-seven out of 54 patients (69%) suffered fractures of the forearm, 10/54 (19%) patients of the humerus and 7/54 (13%) patients of the forearm and the humerus. The median MESS and Injury Severity Score (ISS) for all patients was 5 (range: 3-10) and 9 (range: 4-50), respectively. Seventeen out of 54 patients (31%) were diagnosed with a MESS≥7. Twenty-one out of 54 patients (39%) suffered severe vascular injuries and 22/54 (41%) patients suffered injuries of neural structures. Throughout the therapy process, 6/54 (11%) patients died. Definite limb salvage was achieved in 45 (94%) of the 48 survivors, of whom 9/45 (20%) subjects had a MESS≥7. DISCUSSION: It became apparent that definite limb salvage could be achieved in the mangled upper extremity regardless of MESS. It should be noted that in the current study, limb functionality was not assessed. However, without a standardized scoring system, there might be significant risk of salving dysfunctional upper limbs. LEVEL OF EVIDENCE: IV: retrospective or historical series.

Global Forum: Fractures in the Elderly.

Fractures in the elderly are increasing in incidence and becoming a major health issue in many countries. With an increasing number of the elderly living to an older age, the problems associated with fractures will continue to increase. We describe the epidemiology of fractures in the elderly and identify six fracture patterns in the population of patients who are sixty-five years of age or older. We also analyzed multiple fractures and open fractures in the elderly and we show that both increase in incidence with older age. The incidence of open fractures in elderly women is equivalent to that in young men. Many factors, including patient socioeconomic deprivation, increase the incidence of fractures in the elderly. More than 90% of fractures follow low-energy falls and the mortality is considerable. Mortality increases with older age and medical comorbidities, but there is also evidence that it relates to premature discharge from the hospital.

Surgical Site Infections in Patients With Type 3 Open Fractures: Comparing Antibiotic Prophylaxis With Cefazolin Plus Gentamicin Versus Piperacillin/Tazobactam.

OBJECTIVES: The purpose of this study was to compare rates of surgical site infection (SSI) in patients with type 3 open fractures who had received cefazolin plus gentamicin versus piperacillin/tazobactam for antibiotic prophylaxis. DESIGN: Retrospective cohort study. SETTING: Level 1 trauma center. PATIENTS: Seven hundred sixty-six patients admitted between January 1, 2004, and December 31, 2012, with open fractures were identified using the National Trauma Data Bank by searching International Classification of Diseases, Ninth Revision (ICD-9) codes. Electronic medical record review revealed 134 patients with type 3 open fractures, of which 72 were included in the final analysis. INTERVENTION: Administration of cefazolin plus gentamicin or piperacillin/tazobactam for type 3 open fracture antibiotic prophylaxis. MAIN OUTCOME MEASUREMENTS: SSI, nonunion, death, and rehospitalization rates at 1 year. RESULTS: Surgical site infection at 1 year occurred in 12 of 37 patients (32.4%) in the cefazolin plus gentamicin group and 11 of 35 patients (31.4%) in the piperacillin/tazobactam group (P = 1.000). Nonunion, death, and rehospitalization rates at 1 year were similar between the 2 groups. Although there was no statistically significant difference in SSI at 30 days between groups, the rate was higher in the cefazolin plus gentamicin group (21.6% vs. 11.4%; P = 0.246). CONCLUSIONS: At our institution, use of piperacillin/tazobactam as compared with cefazolin plus gentamicin for antibiotic prophylaxis in patients with type 3 open fractures showed similar rates of SSI, nonunion, mortality, and rehospitalization at 1 year after injury. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Exchange nailing for femoral diaphyseal fracture non-unions: Risk factors for failure.

The aim of this study was to identify risk factors for failure of exchange nailing for femoral diaphyseal fracture non-unions. The study cohort comprised 40 patients with femoral diaphyseal non-unions treated by exchange nailing, of which six were open injuries. The median time to exchange nailing from primary fixation was 8.4 months. The main outcome measures were union, number of secondary fixation procedures required to achieve union and time to union. Multiple causes for non-union were found in 16 (40%) cases, with infection present in 12 (30.0%) patients. Further surgical procedures were required in nine (22.5%) cases, one of whom (2.5%) required the use of another fixation modality to achieve union. Union was ultimately achieved with exchange nailing in 34/37 (91.9%) patients. The median time to union after the exchange nailing was 9.4 months. Cigarette smoking and infection were risk factors for failure of exchange nailing. Multivariate analysis found infection to be the strongest predictor of exchange failure (p<0.05). Exchange nailing is an effective treatment for aseptic femoral diaphyseal fracture non-union. However, 50% of patients undergoing exchange nailing in the presence of infection required at least one further procedure. It is important to counsel patients of this so that they can plan for it and do not consider that the first exchange operation has failed.

In-Hospital Mortality Following Open and Closed Long Bone Fracture: A Comparative Study.

BACKGROUND: Open fracture is a serious orthopaedic injury that can lead to significant patient morbidity and mortality. There is limited data on the mortality risk for open compared to closed long bone fracture. METHODS: The Nationwide Inpatient Sample was used to identify all patients who were admitted with a long bone fracture in the United States between 1998 and 2010. Cox proportional hazards regression modeling was used to calculate the hazard ratio (HR) and 95% confidence interval (CI) of mortality. RESULTS: After adjusting for age, gender, race, insurance, and comorbidities, the HR of mortality was 2.89 (95% CI, 2.56-3.28; p<0.001) for open compared to closed fracture. Stratified by anatomical site, the HR of mortality for open compared to fracture was 3.43 for femur (95% CI, 2.78-4.23; p<0.001), 2.81 for tibia or fibula (95% CI, 2.17-3.64; p<0.001), 2.54 for humerus (95% CI, 1.81-3.56; p<0.001), and 1.56 for radius or ulna (95% CI, 1.10-2.23; p=0.014). CONCLUSIONS: This data suggests that open fracture carries a worse prognosis compared to closed fracture at the same anatomical site.

Are low-energy open ankle fractures in the elderly the new geriatric hip fracture?

As the geriatric population in the United States continues to increase, ankle fractures in the elderly are predicted to exponentially increase in the future. As such, these injuries will become a common injury seen by physicians in various fields. Currently, no studies discussing low-energy open ankle fractures in the elderly and/or the mortality rate associated with these devastating injuries have been published. The purpose of the present study was to retrospectively review the morality rate associated with low-energy open ankle fractures in the elderly. We retrospectively identified 11 patients >60 years old who had sustained low-energy open ankle fractures and been treated at our institution. The patient demographics, mechanism of injury, wound size, medical comorbidities, treatment, follow-up data, and outcomes were recorded. Low-energy falls were defined as ground level falls from sitting or standing. The mean age of the patients was 70.72 years, with a mean body mass index of 35.93 ± 10.24. Of the 11 patients, 9 (81.81%) had ≥3 comorbidities (i.e., hypertension, diabetes, coronary artery disease, congestive heart failure, and/or chronic obstructive pulmonary disease). The mean size of the medially based ankle wound was 14.18 ± 4.12 cm; 10 (90.90%) were Gustilo and Anderson grade IIIA open ankle fractures. In our study, low-energy open ankle fractures in the elderly, very similar to hip fractures, were associated with a high mortality incidence (27.27%) at a mean of 2.67 ± 2.02 months, and 81.81% of our patients had ≥3 medical comorbidities.

Comparing the predictive value of the pelvic ring injury classification systems by Tile and by Young and Burgess.

INTRODUCTION: Radiology-based classifications of pelvic ring injuries and their relevance for the prognosis of morbidity and mortality are disputed in the literature. The purpose of this study was to evaluate potential differences between the pelvic ring injury classification systems by Tile and by Young and Burgess with regard to their predictive value on mortality, transfusion/infusion requirement and concomitant injuries. PATIENTS AND METHODS: Two-hundred-and-eighty-five consecutive patients with pelvic ring fractures were analyzed for mortality within 30 days after admission, number of blood units and total volume of fluid infused during the first 24h after trauma, the Abbreviated Injury Severity (AIS) scores for head, chest, spine, abdomen and extremities as a function of the Tile and the Young-Burgess classifications. RESULTS: There was no significant relationship between occurrence of death and fracture pattern but a significant relationship between fracture pattern and need for blood units/total fluid volume for Tile (p<.001/p<.001) and Young-Burgess (p<.001/p<.001). In both classifications, open book fractures were associated with more fluid requirement and more severe injuries of the abdomen, spine and extremities (p<.05). When divided into the larger subgroups "partially stable" and "unstable", unstable fractures were associated with a higher mortality rate in the Young-Burgess system (p=.036). In both classifications, patients with unstable fractures required significantly more blood transfusions (p<.001) and total fluid infusion (p<.001) and higher AIS scores. CONCLUSIONS: In this first direct comparison of both classifications, we found no clinical relevant differences with regard to their predictive value on mortality, transfusion/infusion requirement and concomitant injuries.

The outcome of tibial diaphyseal fractures in the elderly.

We describe the outcome of tibial diaphyseal fractures in the elderly (≥ 65 years of age). We prospectively followed 233 fractures in 225 elderly patients over a minimum ten-year period. Demographic and descriptive data were acquired from a prospective trauma database. Mortality status was obtained from the General Register Office database for Scotland. Diaphyseal fractures of the tibia in the elderly occurred predominantly in women (73%) and after a fall (61%). During the study period the incidence of these fractures decreased, nearly halving in number. The 120-day and one-year unadjusted mortality rates were 17% and 27%, respectively, and were significantly greater in patients with an open fracture (p < 0.001). The overall standardised mortality ratio (SMR) was significantly increased (SMR 4.4, p < 0.001) relative to the population at risk, and was greatest for elderly women (SMR 8.1, p < 0.001). These frailer patients had more severe injuries, with an increased rate of open fractures (30%), and suffered a greater rate of nonunion (10%). Tibial diaphyseal fractures in the elderly are most common in women after a fall, are more likely to be open than in the rest of the population, and are associated with a high incidence of nonunion and mortality.

The Jones-Powell Classification of open pelvic fractures: a multicenter study evaluating mortality rates.

BACKGROUND: Historically, open pelvic fractures have a high mortality rate. The Jones-Powell Classification system was developed to assist with morbidity and mortality prediction.The purposes of our study were twofold: 1. Apply the Jones-Powell Classification to mortality rates of open pelvic fractures; 2. Because the original article published on the Jones-Powell Classification was from 1997, there have been advances in the early treatment of pelvic fractures to include the use of the pelvic binder, early diverting colostomies, and emergent angiography. We wanted to examine if any of those acute interventions affected mortality rate. METHODS: This is a retrospective review of all patients presenting with open pelvic fractures at six Level I trauma centers between 2000 and 2006. RESULTS: There were 64 patients with an average age of 34 years (range, 17-57 years). Fourteen had stable pelvic fracture patterns, and 50 had unstable fracture patterns. The overall mortality rate in our study was 15 patients (23%). All patients who died had an unstable pelvic fracture and/or rectal laceration. Sixteen patients had diverting colostomies within 48 hours of injury. There were four patients with rectal lacerations and no patients with diverting colostomies who died. DISCUSSION: In our population group, there was an overall mortality rate of 23%. A Jones-Powell Class 3 injury had a 38% mortality rate. The presence of a rectal laceration may serve as a marker for the severity of the patient's injuries and increased risk of mortality. LEVEL OF EVIDENCE: Epidemiologic study, level IV.

[Clinical treatment of open pelvic fractures associated with perineal injury].

OBJECTIVE: To investigate the method and the effectiveness of open pelvic fractures associated with perineal injury. METHODS: Between August 2000 and July 2010, 16 cases of open pelvic fractures associated with perineal injury were treated. There were 12 males and 4 females with an average age of 41 years (range, 17-69 years). Injury was caused by traffic accidents in 9 cases, by falling from height in 6 cases, and by crushing in 1 case. The mean time between injury and admission was 8 minutes (range, 5-20 minutes). According to Tile classification, 2 cases were rated as type A, 6 as type B, and 8 as type C. The wound size ranged from 5 cm x 3 cm to 15 cm x 12 cm. The perineal injured location included intraperitoneal rectal injury in 2 cases and extraperitoneal anorectal injury in 14 cases. The average injury severity score (ISS) was 29 (range, 25-48). The main treatments included emergency resuscitation, colostomy, external fixation of fractures, repeated debridement with pulsatile irrigation followed by intravenous antibiotics, and vacuum sealing drainage (VSD). RESULTS: In 5 deaths, 3 cases died of hemorrhagic shock and 2 cases died of multiple system organ failure within 4 days of admission. The other 11 cases were followed up 6-46 months (mean, 14 months). The X-ray films showed that bone union was achieved after 2-4 months of operation. Infection in varying degree occurred at perineal wounds; second stage healing of wounds was achieved in 10 cases after debridement and VSD treatment, and wound healed in 1 case after gracilis muscle flap repair. No anal incontinence occurred in the patients having anorectal injury during follow-up. CONCLUSION: For patients with perineal injury and open pelvic fractures, the following treatments should be carried out so as to obtain good effectiveness: early anti-shock, protection of important organ function, treatment of complications, late resistance to infection and stability restoration of the pelvic ring, functional repair and reconstruction of rectum and anal canal and urinary tract.

Importance of an intact dura in management of compound elevated fractures; a short series and literature review.

PURPOSE: To describe compound elevated fractures (CEFs) of the skull vault, with radiological pictures, management problems and prognosticative factors. METHOD: The authors describe three cases of CEFs of the cranium, their mode of injury, clinical findings, radiological images and management problems. The authors have reviewed the existing literature regarding epidemiological data, neurological status, dural breech, methods of management and final outcome, in respect of CEFs. RESULTS: The first case had no dural breech, the second case had completely shattered dura, with extruding brain matter from the wound, while the third case had an elevated bone flap in consequence to large extradural haematoma. The patients with intact dura had relatively favourable outcome, when compared to patients with shattered dura. Three cases are added to the existing 10 such cases described in English literature. The major cause of unfavourable outcome remains sepsis and the presence of intact dura places these cases in the relatively safe category, regarding infective complications. CONCLUSION: The authors attempt at highlighting the importance of intact dura with such an injury. The review of literature supports favourable outcomes in patients having no dural breech.

Open clavicle fractures: patterns of trauma and associated injuries.

OBJECTIVES: To describe the demographic distribution, mechanism of injury, and associated injuries of patients sustaining open clavicle fractures. DESIGN: Retrospective case series. SETTING: Level I trauma center. PATIENTS/PARTICIPANTS: Trauma registry data from all patients who required admission to the hospital from October 1995 through January 2010, specifically patients with open clavicle fractures. INTERVENTION: Not applicable. MAIN OUTCOME MEASUREMENTS: The patterns of open clavicle fractures and their association with severe, nonorthopaedic injuries (head, thoracic, and great vessel). RESULTS: Fifty-three patients with open clavicle fractures were identified, and they were organized by mechanism of injury: 21 sustained blunt injuries, 26 penetrating injuries, and six not specified. No difference between blunt and penetrating injuries existed with respect to age, Injury Severity Score, inpatient days, or mortality rates. Blunt injuries were more likely associated with head injuries (52%) versus penetrating injuries (22%), but penetrating injuries were more likely associated with a great vessel injury (27% vs 7%, respectively), all statistically significant (P = 0.0487). CONCLUSIONS: Open clavicle fractures are rare injuries. Patients often have associated head, thoracic, and great vessel injuries. Penetrating injuries have higher rates of great vessel injuries and that blunt force injuries have higher rates of head injuries.

[Trauma-associated bleeding in the severely injured. Relevance, risk stratification and current therapy approaches]. / Traumaassoziierte Blutung beim Schwerverletzten. Relevanz, Risikostratifizierung und aktuelle Therapieansätze.

Of all trauma-related deaths 40% are due to exsanguination. The causes for acute, hemorrhaging are uncontrolled bleeding sources and the development of acute posttraumatic coagulopathy. Clinical observations and recent research results emphasize the key role of this disorder in acute trauma care. The present synopsis summarizes the results from different analyses based on datasets from severely injured patients derived from the Trauma Register of the German Trauma Society (DGU) on frequency, potential triggers and strategies to manage acute posttraumatic coagulopathy. In an extension to this work a clinical scoring system for early identification of patients at high risk for ongoing bleeding is presented. High risk patients seem to benefit from a more balanced transfusion regimen.
