[PMID: 39059112 DOI: 10.1016/j.amjsurg.2024.115828] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2024] [Revised: 06/25/2024] [Accepted: 07/03/2024] [Indexed: 07/28/2024]
Abstract
INTRODUCTION Preperitoneal pelvic packing (PPP) has been advocated as a damage control procedure for pelvic fracture bleeding, despite of weak evidence. METHODS Matched cohort study, TQIP database. Patients with isolated severe blunt pelvic fractures (pelvis abbreviated injury score [AIS] ≥ 3, AIS ≤2 in all other body regions) were included. Patients who underwent PPP were matched to patients with no PPP, 1:3 nearest propensity score. Matching was performed based on demographics, vital signs on admission, comorbidities, injury characteristics, type and timing of initiation of VTE prophylaxis, and additional procedures including laparotomy, REBOA, and angioembolization. RESULTS 64 patients with PPP were matched with 182 patients with No-PPP. PPP patients had higher in-hospital mortality (14.1 % vs 2.2 % p < 0.001) and higher rates of VTE and DVT (VTE: 14.1 % vs 4.4 % p = 0.018, DVT: 10.9 % vs 2.2 % p = 0.008). CONCLUSION PPP is associated with worse survival outcomes and increased rate of VTE and DVT complications.

[PMID: 38835686 PMCID: PMC11145966 DOI: 10.5312/wjo.v15.i5.418] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Revised: 04/09/2024] [Accepted: 04/23/2024] [Indexed: 05/15/2024] Open
Abstract
BACKGROUND Pelvic fractures (PF) with concomitant injuries are on the rise due to an increase of high-energy trauma. Increase of the elderly population with age related comorbidities further complicates the management. Abdominal organ injuries are kindred with PF due to the proximity to pelvic bones. Presence of contrast blush (CB) on computed tomography in patients with PF is considered a sign of active bleeding, however, its clinical significance and association with outcomes is debatable. AIM To analyze polytrauma patients with PF with a focus on the geriatric population, co-injuries and the value of contrast blush. METHODS This retrospective cohort study included 558 patients with PF admitted to level 1 trauma center (01/2017-01/2023). Analyzed variables included: Age, sex, mechanism of injury (MOI), injury severity score (ISS), Glasgow coma scale (GCS), abbreviated injury scale (AIS), co-injuries, transfusion requirements, pelvic angiography, embolization, laparotomy, orthopedic pelvic surgery, intensive care unit and hospital lengths of stay, discharge disposition and mortality. The study compared geriatric and non-geriatric patients, patients with and without CB and abdominal co-injuries. Propensity score matching was implemented in comparison groups. RESULTS PF comprised 4% of all trauma admissions. 89 patients had CB. 286 (52%) patients had concomitant injuries including 93 (17%) patients with abdominal co-injuries. Geriatric patients compared to non-geriatric had more falls as MOI, lower ISS and AIS pelvis, higher GCS, less abdominal co-injuries, similar CB and angio-embolization rates, less orthopedic pelvic surgeries, shorter lengths of stay and higher mortality. After propensity matching, orthopedic pelvic surgery rates remained lower (8% vs 19%, P < 0.001), hospital length of stay shorter, and mortality higher (13% vs 4%, P < 0.001) in geriatric patients. Out of 89 patients with CB, 45 (51%) were embolized. After propensity matching, patients with CB compared to without CB had more pelvic angiography (71% vs 12%, P < 0.001), higher embolization rates (64% vs 22%, P = 0.02) and comparable mortality. CONCLUSION Half of the patients with PF had concomitant co-injuries, including abdominal co-injuries in 17%. Similarly injured geriatric patients had higher mortality. Half of the patients with CB required an embolization.

Abstract
Traumatic pelvic ring injuries continue to represent a major challenge due to the high rates of post-injury mortality of around 30-40% in the peer-reviewed literature. The main root cause of potentially preventable mortality relates to the delayed recognition of the extent of retroperitoneal hemorrhage and post-injury coagulopathy. The understanding of the underlying pathophysiology of pelvic trauma is predicated by classification systems for grading of injury mechanism and risk stratification for developing post-injury coagulopathy with subsequent uncontrolled exsanguinating hemorrhage. This review article elaborates on the current understanding of the pathophysiology of severe pelvic trauma with a focus on the underlying mechanisms of retroperitoneal bleeding and associated adverse outcomes.

Abstract
PURPOSE OF REVIEW While the principles of damage control surgery - rapid hemorrhage and contamination control with correction of physiologic derangements followed by delayed definitive reconstruction - have remained consistent, forms of damage control intervention have evolved and proliferated dramatically. This review aims to provide a historic perspective of the early trends of damage control surgery as well as an updated understanding of its current state and future trends. RECENT FINDINGS Physiologically depleted patients in shock due to both traumatic and nontraumatic causes are often treated with damage control laparotomy and surgical principles. Damage control surgery has also been shown to be safe and effective in thoracic and orthopedic injuries. Damage control resuscitation is used in conjunction with surgical source control to restore patient physiology and prevent further collapse. The overuse of damage control laparotomy, however, is associated with increased morbidity and complications. With advancing technology, catheter- and stent-based endovascular modalities are playing a larger role in the resuscitation and definitive care of patients. SUMMARY Optimal outcome in the care of the most severely injured patients requires judicious use of damage control surgery supplemented by advancements in resuscitation and surgical adjuncts.

Abstract
Determining the true availability of resources and understanding the level of training of surgeons involved in the treatment of patients with pelvic fractures and haemorrhagic shock is critical. In the herein study, the availability of technical, technological, and human resources for the care of this injury in Latin America region was analysed, and the preferences of orthopaedic trauma surgeons when performing interventions for the diagnosis and treatment of patients with pelvic trauma and associated haemorrhagic shock was described. A cross sectional web-based survey containing questions on knowledge, attitudes, and practices with respect to imaging resources, emergency pelvic stabilization methods, and interventions used for bleeding control was sent to 948 Latin America orthopaedic trauma surgeons treating pelvic fractures in the emergency department. Differences between regional clusters, level of training, type of hospital, and pelvic surgery volume were assessed. 368 responses were obtained, with 37.5% of respondents reporting formal training in pelvic surgery and 36.0% having available protocol for managing these patients. The most frequently used interventions were the supra-acetabular pelvic external fixator and pelvic packing. Limited hospital and imaging resources are available for the care of patients with pelvic trauma and associated haemorrhagic shock throughout Latin America. In addition, the training of orthopaedic trauma surgeons dealing with this type of injury and the volume of pelvic surgeries per year is heterogeneous. It should be urgently considered to develop management protocols adapted to Latin America according to the availability of resources, as well as to promote training in this severe life-threatening traumatic condition.

Abstract
BACKGROUND Reconstruction of the pelvic ring anatomy in unstable anterior pelvic ring injuries is a significant step to reduce the mortality rate associated with these injuries efficiently. There is a debate on using either an anterior subcutaneous pelvis internal fixator (INFIX) or an anterior supra-acetabular external fixator (EXFIX) to manage an unstable anterior pelvic ring fracture.
AIM To compare the functional and radiological outcomes and complications of INFIX vs EXFIX in managing unstable pelvic ring injuries.
METHODS A prospective cohort study included 54 patients with unstable pelvic ring fractures. The patients were divided into two groups; the INFIX group, in which 30 cases were fixed by INFIX, and the EXFIX group, in which 24 patients were treated by EXFIX. The average age in the EXFIX group was 31.17 years (16-57 years), while in the INFIX group, it was 34.5 years (17-53 years). The study included 20 (66.7%) males and 10 (33.3%) females in the INFIX group and 10 (41.7%) males and 14 (58.3%) females in the EXFIX group. The radiological outcomes were evaluated using Matta and Tornetta's score, and the functional outcomes using the Majeed score.
RESULTS The results revealed a statistically significant difference between both groups (P = 0.013) regarding radiological outcomes, according to Matta and Tornetta's score in favor of the INFIX group. Sitting, standing, and walking abilities were measured at a 3-mo follow-up visit using Majeed score modules. It was significantly better among the INFIX group than the EXFIX group in all three modules. At the final follow-up, both groups had no statistically significant difference according to the Majeed score; 92.35 in the INFIX group and 90.99 in the EXFIX group (P = 0.513). A lower surgical site infection rate was noticed in the INFIX group (P = 0.007).
CONCLUSION Anterior subcutaneous pelvis INFIX is associated with better radiological outcomes and a lower infection rate than anterior supra-acetabular EXFIX in managing patients with unstable anterior pelvic ring fractures.

Abstract
Secure fixation by inserting a half-pin into the iliac crest as a pelvic external fixator is important. However, the thickness of the iliac bone depends on its location and this makes it difficult to insert a half-pin accurately. The iliac crest is especially narrow in the paediatric pelvis, making it difficult to insert the half-pin accurately compared with an adult pelvis. A case of pelvic external fixation is described for a paediatric pelvic fracture in this report, in which preoperative planning for half-pin insertion was performed accurately using a preoperative three-dimensional CT based on an intraoperative support device that uses the functional pelvic plane as a reference.

Abstract
BACKGROUND Preperitoneal packing (PPP) has been widely accepted as a damage control technique for severe bleeding from pelvic fractures. It is supposed to work by direct compression and tamponade of the bleeding source in the pelvis and it has been suggested to be effective for both venous and arterial bleeding. However, there is little evidence to support its efficacy or the ability to place the laparotomy pads in proximity of the desired location. METHODS Bilateral PPP was performed on 10 fresh human cadavers, followed by laparotomy and measurements of resultant pad placement in relation to critical anatomic structures. RESULTS A total of 20 assessments of laparotomy pad placement were performed. Following completion of PPP, a midline laparotomy was performed to determine proximity and closest distance of the laparotomy pads to sites of potential bleeding in pelvic fractures. In almost all cases, the pad placement was not contiguous with the key anatomic structure with mean placement 3.9 + 1.1 cm from the sacroiliac joint, 3.5 + 1.6 cm from the common iliac artery, 1.1 + 1.2 cm from the external iliac artery, 2.8 + 0.8 cm from the internal iliac artery, and 2.3 + 1.2 cm from the iliac bifurcation. Surgeon experience resulted in improved placement relative to the sacroiliac joint, however the pads still did not directly contact the target point. CONCLUSION This human cadaver study has shown that PPP, even in experienced hands, may not be placed in significant proximity of anatomical structures of interest. The role of PPP needs to be revisited with better clinical or human cadaver studies.

Abstract
INTRODUCTION Resuscitative endovascular balloon occlusion of the aorta (REBOA) is advocated for hemorrhage control in pelvic fracture patients in shock. We evaluated REBOA in patients undergoing preperitoneal pelvic packing (PPP) for pelvic fracture-related hemorrhage. METHODS Retrospective, single-institution study of unstable pelvic fractures (hemodynamic instability despite 2 units of red blood cells (RBCs) and fracture identified on x-ray). Management included the placement of a Zone III REBOA in the emergency department (ED) for systolic blood pressure <80 mmHg. All PPP patients were included and analyzed for injury characteristics, transfusion requirements, outcomes and complications. Additionally, patients who received REBOA (REBOA+) were compared to those that did not (REBOA-). RESULTS During the study period (January 2015 - January 2019), 652 pelvic fracture patients were admitted; 78 consecutive patients underwent PPP. Median RBCs at PPP completion compared to 24 h post-packing were 11 versus 3 units (p<0.05). Median time to operation was 45 min. After PPP, 7 (9%) patients underwent angioembolization. Mortality was 14%. No mortalities were due to ongoing pelvic fracture hemorrhage or physiologic exhaustion; all were a withdrawal of life sustaining support, most commonly due to neurologic insults (TBI/fat emboli = 6, stroke/spinal cord injury = 3). REBOA+ patients (n = 31) had a significantly higher injury severity score (45 vs 38, p<0.01) and higher heart rate (130 vs 118 beats per minute, p = 0.04) than REBOA-. The systolic blood pressure, base deficit, and number of RBCs transfused in the ED, and time spent in the ED were similar between groups. REBOA+ had a higher median transfusion of RBCs at PPP completion (11 units vs 5 units, p<0.01) but similar RBC transfusion in the 24 h after PPP (2 vs 1 units, p = 0.27). Mortality, pelvic infection, and ICU length of stay was not different between these cohorts. CONCLUSION PPP with REBOA was utilized in more severely injured patients with greater physiologic derangements. Although REBOA patients required greater transfusion requirements, there were no deaths due to acute pelvic hemorrhage. This suggests the combination of REBOA with PPP provides life-saving hemorrhage control in otherwise devastating injuries.

Abstract
Patients presenting with hemodynamic instability associated with pelvic fractures continue to have very high mortality and surgeons continue to seek damage control strategies that may improve survival. Strategies usually require massive transfusion, immediate pelvic stabilization and another adjunctive maneuver's such as angioembolization or preperitoneal pelvic packing to prevent hemorrhagic death. One current intervention that has regained some popularity in lieu of resuscitative thoracotomy is the Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA). This requires some manner of femoral arterial access to insert a balloon into the aorta and increase central blood pressure (cardiac and cerebral perfusion) and control active pelvic bleeding. Based on several animal models and an increasing number of publications, many US level I trauma centers have now opted to use REBOA in carefully selected patients showing signs of near cardiac arrest from non-compressible torso hemorrhage. Description of the current advances in aortic occlusion using catheter-based technology in the setting of severe shock for non-compressible torso hemorrhage from pelvic ring fracture is the purpose of this report.

Abstract
A multidisciplinary approach to the management of pelvic ring injuries has been shown to decrease mortality rates. The primary goals within the emergency room are to assess, resuscitate, and stabilize the patient. The Advanced Trauma Life Support protocol guides the initial assessment of the patient. A pelvic binder or sheet should be applied to help to provide reduction of the fracture and temporary stabilization. The trauma team becomes the primary service for the patient as he or she transitions away from the emergency department. The trauma team must effectively communicate with and serve as the liaison between other specialists as injuries are identified. emodynamic stability should be closely monitored in patients with pelvic ring injuries, involving the assessment of vital signs, imaging findings, and clinical judgment. Angioembolization and peritoneal packing may play a role in helping to control hemorrhage. Urologists should be consulted if a Foley catheter cannot be passed or there is concern for urethral or bladder injury. Further imaging or urologic intervention may be necessary. Orthopaedic surgeons can help to assess the patient, classify the injury, and assist in temporary stabilization while planning definitive fixation.

Abstract
INTRODUCTION Treatment of pelvic trauma related hemorrhage is challenging and remains controversial. In hemodynamically unstable patients suspected for massive bleeding, pre-peritoneal packing (PPP) with temporary external fixation (EF) and subsequent trans-arterial embolization (TAE) can be performed in order to control bleeding. In hemodynamically stable patients suspected for minor to moderate bleeding, primary TAE with EF may be performed. The goal of this study was to determine effectiveness and safety of both strategies. METHODS Retrospectively, patients that received treatment for pelvic trauma-related hemorrhage at two level 1 trauma centers located in the United States between January 2001 and January 2019 were evaluated. Both centers advocate subsequent TAE in addition to PPP and EF in hemodynamically unstable patients, and primary TAE in stable patients. Demographic and clinical data was collected and mortality, ischemic and infectious complications were determined. RESULTS In total, 135 patients met the inclusion criteria. Of these, 61 hemodynamically unstable patients suspected for massive pelvic bleeding underwent primary PPP (45%) and 74 stable patients suspected for minor/moderate bleeding underwent primary TAE (55%). In total, 37/61 primary PPP patients underwent EF (61%) and 48 underwent adjunct TAE (79%), performed bilaterally in 77% and unselective by use of gelfoam in 72% of cases. Primary TAE patients received embolization bilaterally in 49% and unselective in 35% of cases. Exsanguination-related deaths were found in 7/61 primary PPP patients (11%). There were none among the primary TAE patients. Potentially ischemic in-hospital complications, of which one could be considered severe (gluteal necrosis), occurred more in patients that received bilateral unselective TAE compared to all other TAE patients (p=0.02). CONCLUSION Primary TAE appears to be an effective and safe adjunct for (minor) pelvic hemorrhage in hemodynamically stable patients. Primary PPP followed by EF and adjunct bilateral unselective TAE with gelfoam appears effective for those suspected of massive pelvic bleeding. This unselective embolization approach using gelfoam might be related to (ischemic) complications. When considering the amount and severity of complications and the severity of pelvic trauma, these might not outweigh the benefit of fast hemorrhage control.

Abstract
BACKGROUND The timing of definitive surgical stabilization is a controversial topic of pelvic and acetabular fracture (PAF) management. Historically, staged care with delayed definitive fixation was recommended; however, more recently, some centers have shown early definitive fixation to be feasible in most patients. We hypothesized that time to definitive fixation of PAF decreased without adverse outcomes. METHODS A level 1 trauma center's prospective pelvic fracture database was retrospectively analyzed. A total of 341 of the 1,270 consecutive PAF patients had surgery between January 2009 and December 2018. Demographics, polytrauma status, hemodynamic stability, time to definitive operation, length of intensive care unit stay, hospital length of stay, mortality were recorded. Data is presented as mean ± SD, percentages. Statistical significance was determined at p < 0.05. RESULTS There were 34 ± 8 per year operatively treated PAF patients during the study period. The demographics (age, 44.1 ± 18 years; 74.5% males) and injury severity (Injury Severity Score, 20; interquartile range, 16-29) did not change. Time to definitive fixation on average was 85 ± 113 hours (range, 0.8-1286 hours). Linear regression analysis demonstrated a decrease in time to definitive fixation considering all patients (β = -0.186, p = 0.003). pelvic ring fractures with polytrauma (β = -1.404, p = 0.03). and hemodynamically unstable patients (β = -1.428, p = 0.037). There was no significant change in mortality, length of stay, or intensive care unit length of stay for the overall cohort or any subgroup. CONCLUSION Time to definitive fixation in PAF has decreased during the last decade, with the largest decrease in time to fixation occurring in the hemodynamically unstable and pelvic fracture with polytrauma cohorts. The timely definitive internal fixation is achievable without increased length of stay. LEVEL OF EVIDENCE Therapeutic/care management, level IV.

Abstract
Pelvic ring injuries (PRI) are among the most difficult injuries to deal with in orthopedic trauma. When these injuries are accompanied by hemodynamic instability their management becomes significantly more complex. A methodical assessment and expeditious triage are required for these patients followed by adequate resuscitation. A major triage decision is whether these patients should undergo arterial embolization in the angiography suit or prompt packing and pelvic stabilization in the operating room. Patient characteristics, fracture type and injury characteristics are taken into consideration in the decision-making process. In this review we discuss the acute evaluation, triage and management of PRIs associated with hemodynamic instability. An evidence based and protocol driven approach is necessary in order to achieve optimal outcomes in these patients.

Abstract
BACKGROUND Increasing numbers of unstable pelvic ring fractures, due to the ongoing demographic change and improvements in the rescue of high-energy traumatic events, are challenging trauma and orthopedic surgeons. While initial installation of an external fixation device is often necessary, placement of iliac crest pins can be difficult due to the complex osteology of the ilium. HYPOTHESIS We aim to analyze (1) the length, localization and angulation of the iliac pillar and (2) to define the dimensions of the surgical corridor for a better understanding of pin entry point and trajectory, thus preventing shortcomings in anterior external fixation of pelvic ring injuries. METHODS Twenty hemipelvises from 10 fresh-frozen cadaveric torsos (3 female, 7 males; mean age 80.2 years) were harvested. The following measurements were taken with digital calipers: Location of the iliac pillar in relation to the anterior superior iliac spine and to the acetabulum roof, mean length and diameter of the iliac pillar, maximum diameter of the iliac pillar. In addition we measured the width of the different bone layers. RESULTS The mean length of the hourglass shaped iliac pillar was 107.04mm with a mean width of 17.0mm (min. 15.1; max. 19.2). The mean distance to the anterior superior iliac spine was 69.00mm (min. 64.8; max. 73.4). The mean maximum width of the iliac pillar was 12.16mm (min. 9.4; max. 13.8). Caudally the line describing the iliac pillar intercepts the cranial acetabular rim at 12 o'clock. The smallest mean diameter of the cancellous bone was 7.5mm±2.0. CONCLUSION The iliac pillar is part of the complex osteology of the human pelvis. A cohesive description of its location and dimensions has been lacking. Successful treatment of pelvic fracture depends on an optimal preoperative planning, accurate overall reduction, and stable fixation. We described the origin and angulation to provide a good bone stock for external fixation pin and the width of the different bone layers. This study therefore contributes by facilitating a thorough understanding of pelvic osteology and describing the location and dimensions of an optimal osseous pathway.

Abstract
BACKGROUND In blunt trauma, orthopedic injuries are often associated with cerebral and torso injuries. The optimal timing for definitive care is a concern. The aim of the study was to develop evidence-based guidelines for damage-control orthopedic (DCO) and early total care (ETC) of pelvic and long-bone fractures, closed or open, and mangled extremities in adult trauma patients with and without associated injuries. METHODS The literature since 2000 to 2016 was systematically screened according to Preferred Reporting Items for Systematic Reviews and meta-analyses protocol. One hundred twenty-four articles were reviewed by a panel of experts to assign grade of recommendation and level of evidence using the Grading of recommendations Assessment, Development, and Evaluation system, and an International Consensus Conference, endorsed by several scientific societies was held. RESULTS The choice between DCO and ETC depends on the patient's physiology, as well as associated injuries. In hemodynamically unstable pelvic fracture patient, extraperitoneal pelvic packing, angioembolization, external fixation, C-clamp, and resuscitative endovascular balloon occlusion of the aorta are not mutually exclusive. Definitive reconstruction should be deferred until recovery of physiological stability. In long bone fractures, DCO is performed by external fixation, while ETC should be preferred in fully resuscitated patients because of better outcomes. In open fractures early debridement within 24 hours should be recommended and early closure of most grade I, II, IIIa performed. In mangled extremities, limb salvage should be considered for non-life-threatening injuries, mostly of upper limb. CONCLUSION Orthopedic priorities may be: to save a life: control hemorrhage by stabilizing the pelvis and femur fractures; to save a limb: treat soft tissue and vascular injuries associated with fractures, stabilize fractures, recognize, and prevent compartmental syndrome; to save functionality: treat dislocations, articular fractures, distal fractures. While DCO is the best initial treatment to reduce surgical load, ETC should be applied in stable or stabilized patients to accelerate the recovery of normal functions.

Abstract
OBJECTIVES The objectives of this study were to gather an expert opinion survey and to evaluate the suitability of summarized indications and interventions for DCO. BACKGROUND The indications to perform temporary surgery in musculoskeletal injuries may vary during the hospitalization and have not been defined. We performed a literature review and an expert opinion survey about the indications for damage control orthopaedics (DCO). METHODS Part I: A literature review was performed on the basis of the PubMed library search. Publications were screened for damage control interventions in the following anatomic regions: "Spine", "Pelvis", "Extremities" and "Soft Tissues". A standardized questionnaire was developed including a list of damage control interventions and associated indications. Part II: Development of the expert opinion survey: experienced trauma and orthopaedic surgeons participated in the consensus process. RESULTS Part I: A total of 646 references were obtained on the basis of the MeSH terms search. 74 manuscripts were included. Part II: Twelve experts in the field of polytrauma management met at three consensus meetings. We identified 12 interventions and 79 indications for DCO. In spinal trauma, percutaneous interventions were determined beneficial. Traction was considered harmful. For isolated injuries, a new terminology should be used: "MusculoSkeletal Temporary Surgery". CONCLUSION This review demonstrates a detailed description of the management consensus for abbreviated musculoskeletal surgeries. It was consented that early fixation is crucial for all major fractures, and certain indications for DCO were dropped. Authors propose a distinct terminology to separate local (MuST surgery) versus systemic (polytrauma: DCO) scenarios.

Achievable pin spanning angulation in anterosuperior pelvic external fixation. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2020; 30:1163-1170. [PMID: 32358714 DOI: 10.1007/s00590-020-02684-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/12/2020] [Accepted: 04/22/2020] [Indexed: 11/26/2022]
Abstract
INTRODUCTION Pelvic external fixation using anterosuperior pins provides a quick method of stabilization without necessitating fluoroscopic guidance. Various locations, depths, and inclinations have been cited for external fixator pins; however, the existing literature lacks clear indications for the angular difference between pins. Thus, we aimed to determine the greatest degree of sagittal pin spanning angulation (SPSA) between two iliac crest pins and how intraosseous depth (ID) affects these angulations. MATERIALS AND METHODS A newly developed computer algorithm produced cross sections of 3D pelvic reconstructions in the sagittal plane in 5° increments. Computer-generated pins with IDs of 60, 75, and 90 mm were positioned in 5° increments transversely. Pins were assessed for cortical containment to define values for SPSA and transverse pin spanning angulation (TPSA). RESULTS A bimodal distribution revealed varying degrees of insertion frequency and SPSA, cranially and caudally. The caudal distribution exhibited greater cortical containment with larger values for SPSA and TPSA. The highest insertion frequency (85.7%) and largest SPSA (155°) were observed for the 60-mm ID. Increasing ID resulted in further bony penetration and smaller values for SPSA and TPSA. CONCLUSIONS Expanding the degree of SPSA between inserted pins in anterosuperior pelvic external fixation can be challenging due to the thinning of the iliac wing, which affords a narrow corridor for intraosseous pin containment. An ID of 60 mm allows larger degrees of SPSA while maintaining higher rates of cortical pin containment when compared to pins with greater IDs.

Abstract
Background Pelvic ring fracture is often combined with other injuries and such patients are considered at high risk of mortality and complications. There is controversy regarding the gold standard protocol for the initial treatment of pelvic fracture. The aim of this study was to assess which risk factors could affect the outcome and to analyze survival using our multidisciplinary institutional protocol for traumatic pelvic ring fracture. Material and methods This retrospective study reviewed patients who sustained an unstable pelvic ring fracture with Injury Severity Score (ISS) ≥ 5. All patients were admitted to the emergency department and registered in the Trauma Registry System of a level I trauma center from January 1, 2008, to December 31, 2017. The annular mortality rate after the application of our institutional protocol was analyzed. Patients with different systems of injury and treatments were compared, and regression analysis was performed to adjust for factors that could affect the rate of mortality and complications. Results During the 10-year study period, there were 825 unstable pelvic ring injuries, with a mean ISS higher than that of other non-pelvic trauma cases. The annual mortality rate declined from 7.8 to 2.4% and the mean length of stay was 18.1 days. A multivariable analysis showed that unstable initial vital signs, such as systolic blood pressure < 90 mmHg (odds ratio [OR] 2.53; confidence interval [CI] 1.11–5.73), Glasgow Coma Scale < 9 (OR 3.87; CI 1.57–9.58), 24 > ISS > 15 (OR 4.84; CI 0.85–27.65), pulse rate < 50 (OR 11.54; CI 1.21–109.6), and diabetes mellitus (OR 3.18; CI 1.10–9.21) were associated with higher mortality. No other specific system in the high Abbreviated Injury Scale increased the rates of mortality or complications. Conclusion Poor initial vital signs and Glasgow Coma Scale score, higher ISS score, and comorbidity of diabetes mellitus affect the mortality rate of patients with unstable pelvic ring fractures. No single system of injury was found to increase mortality in these patients. The mortality rate was reduced through institutional efforts toward the application of guidelines for the initial management of pelvic fracture.

Abstract
Treatment of anterior pelvic ring injuries involves both acute stabilization during the initial resuscitation and definitive fixation. Definitive management has evolved substantially over the past 40 years with improved patient mobilization and long-term outcomes. Although its use has recently declined, external fixation remains a favorable option in certain situations. Symphyseal plating is the preferred technique for stabilization of symphyseal diastasis because of superior stability and low morbidity. Ramus screws can be effective for simple ramus fractures but require a careful technique because of the proximity of neurovascular structures. The subcutaneous internal fixator provides a good option for obese patients in whom external fixation would be poorly tolerated. Regardless of fixation strategy, posterior ring reduction and stabilization is crucial.

Abstract
PURPOSE OF REVIEW Complex traumatic pelvic ring disruptions are associated with a high mortality rate due to associated retroperitoneal hemorrhage, traumatic-hemorrhagic shock, and postinjury coagulopathy. The present review provides an update on current management strategies to improve survival rates form hemodynamically unstable pelvic ring injuries. RECENT FINDINGS Recently published international consensus guidelines have attempted to standardize the classification of hemodynamically unstable pelvic ring injuries and provided classification-based management algorithms for acute resuscitation and pelvic ring stabilization. SUMMARY Acute management strategies for pelvic ring disruptions with associated hemorrhagic shock include resuscitative endovascular balloon occlusion of the aorta for patients 'in extremis' in conjunction with point-of-care guided resuscitation for postinjury coagulopathy. Recent data indicate that a protocol of early pelvic external fixation in conjunction with direct preperitoneal pelvic packing and subsequent angioembolization in patients with ongoing hemorrhage results in significantly improved survival from retroperitoneal exsanguinating hemorrhage in at-risk patients with historic mortality rates as high as 50-60%.

Abstract
AIM There is not adequate evidence to establish whether external fixation (EF) of pelvic fractures leads to a reduced mortality. We used the Japan Trauma Data Bank database to identify isolated unstable pelvic ring fractures to exclude the possibility of blood loss from other injuries, and analyzed the effectiveness of EF on mortality in this group of patients. PATIENTS AND METHODS This was a registry-based comparison of 1163 patients who had been treated for an isolated unstable pelvic ring fracture with (386 patients) or without (777 patients) EF. An isolated pelvic ring fracture was defined by an Abbreviated Injury Score (AIS) for other injuries of < 3. An unstable pelvic ring fracture was defined as having an AIS ≥ 4. The primary outcome of this study was mortality. A subgroup analysis was carried out for patients who required blood transfusion within 24 hours of arrival in the Emergency Department and those who had massive blood loss (AIS code: 852610.5). Propensity-score matching was used to identify a cohort like the EF and non-EF groups. RESULTS With the use of propensity-score matching using the completed data, 346 patients were matched. When the propensity-score matching was adjusted, EF was associated with a significantly lower risk of death (p = 0.047). In the subgroup analysis of patients who needed blood transfusion within 24 hours and those who had massive blood loss, EF was associated with a significantly lower risk of death in patients who needed blood transfusion within 24 hours (p = 0.014) and in those with massive blood loss (p = 0.016). CONCLUSION The use of EF to treat unstable pelvic ring fractures was associated with a significantly lower risk of death, especially in patients with severe fractures.

Abstract
PURPOSE The aim of this study was to determine whether the outcomes of patients with hemodynamically unstable pelvic bone fractures changed after the introduction of a protocol including extraperitoneal pelvic packing (EPP) and the establishment of a trauma center. METHODS We analyzed data of adult patients (≥ 18 years old) with hemodynamically unstable pelvic bone fractures who visited a single trauma center from February 2009 to October 2016. In July 2014, a new protocol for pelvic fractures was implemented, and a trauma center was established. Therefore, patient outcomes were compared by period (period I: pre-protocol vs. period II: post-protocol). RESULTS Seventy-nine patients with hemodynamically unstable pelvic bone fractures were recruited. The time to angiographic embolization after arrival at the emergency room decreased significantly in period II when compared to period I (182.9 vs. 268.9 min, respectively, p < 0.001). The time required to intervention, including EPP, also decreased, from 268.9 ± 132.4 min in period I to 141.9 ± 79.9 min in period II (p < 0.001). The overall mortality rate decreased from 47.2% in period I to 23.3% in period II (p = 0.033), and mortality related to hemorrhagic shock in particular, was significantly lowered, from 27.8% in period I to 4.7% in period II (p = 0.009). CONCLUSIONS The establishment of a trauma center and the implementation of a new protocol that included EPP were effective in the treatment of patients with hemodynamically unstable pelvic fractures.

Abstract
OBJECTIVE To investigate the safety and feasibility of performing definitive fracture fixation in multiply injured patients in the presence of an open abdomen after laparotomy. DESIGN Retrospective observational cohort study. SETTING Level-I academic trauma center. PATIENTS Adult polytrauma patients with the presence of an open abdomen after "damage control" laparotomy and associated major fractures of long bones, acetabulum, pelvis, or spine, requiring surgical repair (n = 81). INTERVENTION Timing of definitive fracture fixation in relation to the timing of abdominal wall closure. MAIN OUTCOME MEASURE Incidence of orthopedic surgical site infections. RESULTS During a 15-year time window from January 1, 2000 until December 31, 2014, we identified a cohort of 294 consecutive polytrauma patients with an open abdomen after laparotomy. Surgical fixation of associated fractures was performed after the index laparotomy in 81 patients. In group 1 (n = 32), fracture fixation occurred significantly sooner despite a concurrent open abdomen, compared with group 2 (n = 49) with abdominal wall closure before fixation (mean 4.4 vs. 11.8 days; P = 0.01). The incidence of orthopaedic surgical site infections requiring a surgical revision was significantly lower in group 1 (3.1%) compared to group 2 (30.6%; P = 0.002). CONCLUSIONS Definitive fracture fixation in the presence of an open abdomen is performed safely and associated with a significant decrease in clinically relevant surgical site infections, compared with delaying fracture fixation until abdominal wall closure. These data suggest that the strategy of imposing a time delay in orthopaedic procedures while awaiting abdominal wall closure is unjustified. LEVEL OF EVIDENCE Therapeutic Level III.

Abstract
Severe pelvic trauma is a challenging condition. The pelvis can create multifocal hemorrhage that is not easily compressible nor managed by traditional surgical methods such as tying off a blood vessel or removing an organ. Its treatment often requires reapproximation of bony structures, damage control resuscitation, assessment for associated injuries, and triage of investigations, as well as multimodality hemorrhage control (external fixation, preperitoneal packing, angioembolization, REBOA [resuscitative endovascular balloon occlusion of the aorta]) by multidisciplinary trauma specialists (general surgeons, orthopedic surgeons, endovascular surgeons/interventional radiologists). This article explores this complex clinical problem and provides a practical approach to its management.

Abstract
BACKGROUND A 2015 American Association for the Surgery of Trauma trial reported a 32% mortality for pelvic fracture patients in shock. Angioembolization (AE) is the most common intervention; the Maryland group revealed time to AE averaged 5 hours. The goal of this study was to evaluate the time to intervention and outcomes of an alternative approach for pelvic hemorrhage. We hypothesized that preperitoneal pelvic packing (PPP) results in a shorter time to intervention and lower mortality. METHODS In 2004, we initiated a PPP protocol for pelvic fracture hemorrhage. RESULTS During the 11-year study, 2,293 patients were admitted with pelvic fractures; 128 (6%) patients underwent PPP (mean age, 44 ± 2 years; Injury Severity Score (ISS), 48 ± 1.2). The lowest emergency department systolic blood pressure was 74 mm Hg and highest heart rate was 120. Median time to operation was 44 minutes and 3 additional operations were performed in 109 (85%) patients. Median RBC transfusions before SICU admission compared with the 24 postoperative hours were 8 versus 3 units (p < 0.05). After PPP, 16 (13%) patients underwent AE with a documented arterial blush.Mortality in this high-risk group was 21%. Death was due to brain injury (9), multiple organ failure (4), pulmonary or cardiac failure (6), withdrawal of support (4), adverse physiology (3), and Mucor infection (1). Of those patients with physiologic exhaustion, 2 died in the operating room at 89 and 100 minutes after arrival, whereas 1 died 9 hours after arrival. CONCLUSIONS PPP results in a shorter time to intervention and lower mortality compared with modern series using AE. Examining mortality, only 3 (2%) deaths were attributed to the immediate sequelae of bleeding with physiologic failure. With time to death under 100 minutes in 2 patients, AE is unlikely to have been feasible. PPP should be used for pelvic fracture-related bleeding in the patient who remains unstable despite initial transfusion. LEVEL OF EVIDENCE Therapeutic study, level IV.

Abstract
Background Floating pubic symphysis (FPS) is a relatively rare injury caused by high-energy mechanisms. There are several fixation methods used to treat FPS, including external fixation, subcutaneous fixation, internal fixation, and percutaneous cannulated screw fixation. To choose the appropriate fixation, it is necessary to study the biomechanical performance of these different methods. The goal of this study was to compare the biomechanical characteristics of six methods by finite element analysis. Methods A three-dimensional finite element model of FPS was simulated. Six methods were used in the FPS model, including external fixation (Ext), subcutaneous rod fixation (Sub-rod), subcutaneous plate fixation (Sub-plate), superior pectineal plate fixation (Int-sup), infrapectineal plate fixation (Int-ifa), and cannulated screw fixation (Int-scr). Compressive and rotational loads were then applied in all models. Biomechanical characteristics that were recorded and analyzed included construct stiffness, micromotion of the fracture gaps, von Mises stress, and stress distribution. Results The construct stiffness of the anterior pelvic ring was decreased dramatically when FPS occurred. Compressive stiffness was restored by the three internal fixation and Sub-rod methods. Unfortunately, rotational stiffness was not restored satisfactorily by the six methods. For micromotion of the fracture gaps, the displacement was reduced significantly by the Int-sup and Int-ifa methods under compression. The internal fixation methods and Sub-plate method performed well under rotation. The maximum von Mises stress of the implants was not large. For the plate-screw system, the maximum von Mises stress occurred over the region of the fracture and plate-screw joints. The maximum von Mises stress appeared on the rod-screw and screw-bone interfaces for the rod-screw system. Conclusions The present study showed the biomechanical advantages of internal fixation methods for FPS from a finite element view. Superior stabilization of the anterior pelvic ring and fracture gaps was obtained by internal fixation. Subcutaneous fixation had satisfactory outcomes as well. Sub-rod fixation offered good anti-compression, while the Sub-plate fixation provided favorable anti-rotational capacity.

Abstract
Complex pelvic injuries are among the most dangerous and deadly trauma related lesions. Different classification systems exist, some are based on the mechanism of injury, some on anatomic patterns and some are focusing on the resulting instability requiring operative fixation. The optimal treatment strategy, however, should keep into consideration the hemodynamic status, the anatomic impairment of pelvic ring function and the associated injuries. The management of pelvic trauma patients aims definitively to restore the homeostasis and the normal physiopathology associated to the mechanical stability of the pelvic ring. Thus the management of pelvic trauma must be multidisciplinary and should be ultimately based on the physiology of the patient and the anatomy of the injury. This paper presents the World Society of Emergency Surgery (WSES) classification of pelvic trauma and the management Guidelines.

Abstract
In the treatment of unstable pelvic ring fractures, external fixators have the limitation of not adequately stabilizing the injured posterior elements. This article presents a novel and simple technique of temporary external fixation of the pelvic ring, able to produce compression of both the anterior and posterior pelvic elements. A curved flexible carbon-fiber rod is used, pre-tensioned before attachment to supra-acetabular Schanz screws. Although more extensive clinical experience is required, favorable preliminary results in a series of 13 patients with unstable pelvic fracture were encouraging: the aim of closing the posterior and anterior elements of the pelvic ring was achieved in all cases treated with this technique, and 12 patients survived. Radiological results were excellent in 3 cases and good in 9 cases. No major complications, such as secondary displacement, vertical re-displacement or deep infection, were observed. Mean operative time was 25min, compatible with emergency management.

Abstract
Pelvic ring fractures are defined as life-threatening injuries that can be treated surgically with external or internal fixation. The authors report on an 81-year-old woman with an unstable pelvic fracture accompanying multiple traumas that was successfully treated with a less invasive procedure. The patient was injured in a traffic accident and sustained a total of 20 fractures, including pelvic ring, bilateral rib, and lumbar transverse processes fractures, and multiple fractures of both upper and lower extremities. The pelvic ring fracture was unstable with fractures of the bilateral sacrum with right sacroiliac disruption, right superior and inferior pubic rami, left superior pubic ramus, and ischium. During emergency surgery, bilateral external fixation was applied to the iliac crest to stabilize the pelvic ring. Second and third surgeries were performed 11 and 18 days after the first emergency surgery, respectively, to treat the multiple fractures. At the third surgery, the pelvic ring fracture was stabilized surgically using a less invasive posterior fixation technique. In this technique, 2 iliac screws were inserted on each side following an 8-cm midline posterior incision from the S-1 to S-3 spinous process, with the subcutaneous tissue detached from the fascia of the paraspinal muscles. The S-2 spinous process was removed and 2 rods were connected to bilateral iliac screws to stabilize the bilateral ilium in a switchback fashion. A crosslink device was applied to connect the 2 rods at the base of the S-2 spinous process. Following pelvic fixation, percutaneous pedicle screws were inserted into L-4 and L-5 vertebral bodies on both sides, and connected to the cranial rod connecting the bilateral iliac screws, thus completing the lumbopelvic fixation. The postoperative course was favorable with no postoperative complications. At the 10-month follow-up, bone union had been achieved at the superior ramus of the pubis, the patient did not complain of pain, and her activities of daily life returned to preinjury status. Unstable pelvic ring fractures need to be sufficiently stabilized for good surgical outcome. However, to avoid postoperative complications, a less invasive treatment is preferred, particularly in cases with poor general condition. This procedure is less invasive and provides sufficient stabilization to the unstable pelvic ring fracture, and thus is the ideal surgical procedure for such cases.

Abstract
Background An option for emergency control of pelvic hemorrhage is Extra-peritoneal Pelvic Packing (EPP), which addresses the retroperitoneal source of exsanguination in pelvic fractures. The aim of this study was to demonstrate the efficacy of early EPP in reducing mortality due to hemorrhage from pelvic fractures, and to evaluate the impact of packing on transfusion requirements within the first 24 h and ICU length of stay (ICU-LOS). All data pertaining trauma patients admitted from October 2002 and December 2103 with hemodynamic instability and pelvic fractures were selected from the Hospital Trauma Registry. Patients with severe brain injury and bleeding from extra-pelvic sources were excluded. Patient population was divided into two groups: EPP group, including patients admitted from 2009 to 2013, with EPP as part of the treatment algorithm, and NO-EPP group, from 2002 to 2008, without EPP as atherapeutic option. Descriptive statistical analysis was performed on allpatients. Twenty-five patients of each group with similar features were matched using Propensity Score Analysis (PSA). Results Six hundred eighty out of 4659 major trauma (14.6 %) presented a pelvic fracture. In 78 hemodynamically unstable patients (30 in EPP group,48 in NO-EPP group) the major source of bleeding was the pelvis. Among patients selected by PSA early mortality was significantly reduced in EPP group (20 vs 52 %, p = .03) compared to NO-EPP, notwithstanding similar hemodynamic impairment. No difference was observed in transfusion requirements and ICU-LOS. Conclusions The EPP is a safe and quick procedure, able to improve hemodynamic stabilization and to reduce acute mortality due to hemorrhage in patients with pelvic fracture, in combination with optimized transfusion protocol. EPP may be useful as a bridge for time-consuming procedures, such as angio-embolization.

Abstract
High-energy pelvic fractures represent potentially life-threatening injuries due to the risk of acute exsanguinating retroperitoneal hemorrhage. The first report of a severe pelvic ring disruption dates back to Charles Hewitt Moore’s seminal publication from 1851. Significant advantages in the understanding of injury mechanisms and treatment concepts of pelvic ring injuries evolved in the 20th century, and provided the basis to current classification-guided treatment and life-saving “damage control” concepts. However, there is a paucity of reports in the current literature focused on the historic background on the treatment of pelvic ring injuries. The present review was designed to summarize the history and evolution of our current understanding of the mechanisms and management strategies for severe pelvic ring injuries (excluding acetabular fractures which represent a different entity outside of the scope of this article).

Abstract
The modularity and ease of application of modern external fixation has expanded its potential use in the management of fractures and other musculoskeletal conditions. In fracture care, it can be used for provisional and definitive fixation. Short-term provisional applications include "damage control" and periarticular fracture fixation. The risk:benefit ratio of added stability needs to be assessed with each fixator. Soft-tissue management is critical during pin insertion to lessen the risk of loosening and infection. Although provisional fixation is safe for early conversion to definitive fixation, several factors affect the timing of definitive surgery, including the initial injury, external fixator stability, infection, and the physiologic state of the patient.

Abstract
Introduction Pelvic fractures can result in life-threatening hemorrhages. Therefore, pelvic fracture patients must usually be transferred to a trauma center for additional management. We attempted to analyze transferred pelvic fracture patients to determine which diagnostic modalities to use in different treatment settings. Materials and methods From May 1, 2008, to February 28, 2014, patients with pelvic fractures who were transferred from other local hospitals within 24 hours after the trauma were enrolled. We compared the pre-transfer conditions and pelvic X-ray results from the local hospitals between the group of patients that underwent further angioembolization at the trauma center and the group that did not. The role of computed tomography (CT) in the decision-making process (i.e., regarding additional angioembolization) at the different institutions was discussed. Results In total, 751 patients were enrolled in the current study. Of the patients who received further angioembolization at the trauma center, 77.6 % (121/156) had sacro-iliac (SI) joint disruption on their pre-transfer pelvic X-ray; this rate was significantly higher than that of the patients who did not undergo further embolization (77.6 % vs. 25.5 %, p < 0.001). There was no significant difference in the use of pre-transfer CT scans at the local hospitals between the patients who underwent angioembolization and those who did not (53.8 % vs. 50.3 %, p = 0.472). Furthermore, of these patients, there was no significant difference in the length of emergency department stay (from arrival to angioembolization) at the trauma center among the patients who underwent pre-transfer CT scans and those who did not (97.4 ± 69.3 minutes vs. 108.6 ± 21.8 minutes, p = 0.461). Conclusion When managing patients with pelvic fractures, the more attention should be paid to those with SI joint disruption on pelvic X-ray. Because these patients are more likely to require further angioembolization, they should be transferred earlier. Additional CT may be performed after the patient’s transfer to the trauma center to determine subsequent treatment.

Abstract
The management of patients with exsanguinating torso hemorrhage is challenging. Emergency surgery, with the occasional use of resuscitative thoracotomy for patient in extremis, is the current standard. Recent reports of REBOA (resuscitative endovascular balloon occlusion of the aorta) have led to discussions about changing paradigms in the management of patients in both civilian and military are nas. We submit that broad and liberal application of this technique is premature given the current data and in light of historical experience. We propose an algorithm for the management of patients with exsanguinating torso hemorrhage, as well as a set of research questions that we feel can help clarify the role of REBOA in modern trauma care in a variety of trauma settings.

Abstract
Exsanguination is the second most common cause of death in patients who suffer severe trauma. The management of haemodynamically unstable high-energy pelvic injuries remains controversial, as there are no universally accepted guidelines to direct surgeons on the ideal use of pelvic packing or early angio-embolisation. Additionally, the optimal resuscitation strategy, which prevents or halts the progression of the trauma-induced coagulopathy, remains unknown. Although early and aggressive use of blood products in these patients appears to improve survival, over-enthusiastic resuscitative measures may not be the safest strategy. This paper provides an overview of the classification of pelvic injuries and the current evidence on best-practice management of high-energy pelvic fractures, including resuscitation, transfusion of blood components, monitoring of coagulopathy, and procedural interventions including pre-peritoneal pelvic packing, external fixation and angiographic embolisation.
