Traumatismes du bassin [Pelvic trauma]

Les fractures du bassin, groupe polymorphe, sont liées au mécanisme traumatique. L'enjeu des fractures isolées du cotyle est principalement fonctionnel. Les radiographies standards, les scanner 3D et la classification de Letournel orientent le traitement. Ce dernier visera à rétablir une congruence articulaire prévenant la coxarthrose précoce. Les fractures du pelvis surviennent le plus souvent suite à des traumatismes violents, associés à des lésions viscérales, menaçant le pronostic vital. Le bilan radiologique s'intègre dans une prise en charge pluridisciplinaire grâce au scanner. La classification de Tile/AO permet la description des mécanismes et des lésions et une prise en charge adaptée. En cas de chocs hémodynamiques, la stabilisation externe, suivie si nécessaire de l'embolisation, à une place prépondérante. Pelvic trauma A great variety of very polymorphous lesions of pelvic trauma are deffering from each other by their context, their anatomical aspect and therapeutic implication. In the isolated acetabular fractures, function is mainly at stake. The management consists mainly of re-establishing a joint congruence to prevent early coxarthrosis. Pelvic fractures often occur in violent trauma and are associated with visceral lesions, putting vital prognosis at stake. In case of hemodynamic shock, external fracture stabilization when it is indicated associated to embolisation of pelvic bleeding if necessary and after external fixation are preponderant.

Pelvic Fractures in Children Results from the German Pelvic Trauma Registry: A Cohort Study.

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.

Transfusion practice in early trauma management

Introduction: Blood transfusions carry risks and complications. At the University Hospital of Lausanne the need for transfusion in early trauma resuscitation is based on clinical judgment and standard laboratory tests. We aimed to assess the transfusion practice for trauma patients during their early management. Method: Based on 2008 data from the Lausanne Trauma Registry of Acute Care (TRAC), we analyzed all adult trauma patients admitted to the shock room who received blood products or pro-coagulants in shock room and/or during their emergency operation. Demographics, physiological parameters and lab tests were recorded at arrival and at the end of anesthesiologic management. Coagulopathy was defined as PT <70%, PTT >60 sec, Fibrinogen <1 g/l or Thrombocytes <100 x 109 g/l. Results: In 2008, 323 trauma-patients were included in TRAC. 55 patients (17%) received blood products or pro-coagulants. 44 (83%) had an ISS >15 (med 29, IQR 10-35.5). 43 (78.2%) needed an emergency intervention. Coagulopathy was present in 25 patients (45.5%) at arrival vs. 30 (54.5%) after resuscitation (p = 0.446).

Improving prehospital trauma management for skiers and snowboarders - need for on-slope triage?

Background Injuries from skiing and snowboarding became a major challenge for emergency care providers in Switzerland. In the alpine setting, early assessment of injury and health status is essential for the initiation of adequate means of care and transport. Nevertheless, validated standardized protocols for on-slope triage are missing. This article can assist in understanding the characteristics of injured winter sportsmen and exigencies for future on-slope triage protocols. Methods Six-year review of trauma cases in a tertiary trauma centre. Consecutive inclusion of all injured skiers and snowboarders aged >15 (total sample) years with predefined, severe injury to the head, spine, chest, pelvis or abdomen (study sample) presenting at or being transferred to the study hospital. Descriptive analysis of age, gender and injury pattern. Results Amongst 729 subjects (total sample) injured from skiing or snowboarding, 401 (55%, 54% of skiers and 58% of snowboarders) suffered from isolated limb injury. Amongst the remaining 328 subjects (study sample), the majority (78%) presented with monotrauma. In the study sample, injury to the head (52%) and spine (43%) was more frequent than injury to the chest (21%), pelvis (8%), and abdomen (5%). The three most frequent injury combinations were head/spine (10% of study sample), head/thorax (9%), and spine/thorax (6%). Fisher's exact test demonstrated an association for injury combinations of head/thorax (p < 0.001), head/abdomen (p = 0.019), and thorax/abdomen (p < 0.001). Conclusion The data presented and the findings from previous investigations indicate the need for development of dedicated on-slope triage protocols. Future research must address the validity and practicality of diagnostic on-slope tests for rapid decision making by both professional and lay first responders. Thus, large-scale and detailed injury surveillance is the future research priority.

Intra- and postoperative complications of navigated and conventional techniques in percutaneous iliosacral screw fixation after pelvic fractures: Results from the German Pelvic Trauma Registry

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.

[Influence of the pelvic trauma registry of the DGU on treatment of pelvic ring fractures].

Fractures of the pelvic ring are comparatively rare with an incidence of 2-8 % of all fractures depending on the study in question. The severity of pelvic ring fractures can be very different ranging from simple and mostly "harmless" type A fractures up to life-threatening complex type C fractures. Although it was previously postulated that high-energy trauma was necessary to induce a pelvic ring fracture, over the past decades it became more and more evident, not least from data in the pelvic trauma registry of the German Society for Trauma Surgery (DGU), that low-energy minor trauma can also cause pelvic ring fractures of osteoporotic bone and in a rapidly increasing population of geriatric patients insufficiency fractures of the pelvic ring are nowadays observed with no preceding trauma.Even in large trauma centers the number of patients with pelvic ring fractures is mostly insufficient to perform valid and sufficiently powerful monocentric studies on epidemiological, diagnostic or therapeutic issues. For this reason, in 1991 the first and still the only registry worldwide for the documentation and evaluation of pelvic ring fractures was introduced by the Working Group Pelvis (AG Becken) of the DGU. Originally, the main objectives of the documentation were epidemiological and diagnostic issues; however, in the course of time it developed into an increasingly expanding dataset with comprehensive parameters on injury patterns, operative and conservative therapy regimens and short-term and long-term outcome of patients. Originally starting with 10 institutions, in the meantime more than 30 hospitals in Germany and other European countries participate in the documentation of data. In the third phase of the registry alone, which was started in 2004, data from approximately 15,000 patients with pelvic ring and acetabular fractures were documented. In addition to the scientific impact of the pelvic trauma registry, which is reflected in the numerous national and international publications, the dramatically changing epidemiology of pelvic ring fractures, further developments in diagnostics and the changes in operative procedures over time could be demonstrated. Last but not least the now well-established diagnostic and therapeutic algorithms for pelvic ring fractures, which could be derived from the information collated in registry studies, reflect the clinical impact of the registry.

Management Of Severe Thoracic Impalement Trauma Against Two-wheeled Horse Carriage: A Case Report And Literature Review.

Thoracic injuries in general are of great importance due to their high incidence and high mortality. Thoracic impalement injuries are rare but severe due to the combination of cause, effect and result. This study's primary objective is to report the case of a young man who was impaled by a two-wheeled horse carriage shaft while crashing his motorcycle in a rural zone. An EMT-B ferry was called at the crash scene and a conscious patient was found, sustaining a severe impalement injury to the left hemithorax, suspended over the floor by the axial skeleton with the carriage shaft coming across his left chest. As a secondary objective, a literature review of thoracic impalement injuries is performed. Cases of thoracic impalement injury require unique and individualized care based on injury severity and affected organs. Reported protocols for managing impalement injuries are entirely anecdotal, with no uniformity on impaled patient's approach and management. In penetrating trauma, it is essential not to remove the impaled object, so that possible vascular lesions remain buffered by the object, avoiding major bleeding and exsanguination haemorrhage. Severed impaled thoracic patients should be transferred to a specialist centre for trauma care, as these lesions typically require complex multidisciplinary treatment. High-energy thoracic impalement injuries are rare and hold a high mortality rate, due to the complexity of trauma and associated injuries such as thoracic wall and lung lesions. Modern medicine still seems limited in cases of such seriousness, not always with satisfactory results.

A quarter century experience in liver trauma: a plea for early computed tomography and conservative management for all hemodynamically stable patients

Advances in diagnostic imaging and the introduction of damage control strategy in trauma have influenced our approach to treating liver trauma patients. The objective of the present study was to investigate the impact of change in liver trauma management on outcome.

Diagnosis and therapy of acute hemorrhage in patients with pelvic fractures

Within the past 15 years, significant advances in the imaging of multiorgan and complex trauma primarily due to the improvement of cross-sectional imaging have resulted in the optimization of the expedient diagnosis and management of the polytrauma patient. At the forefront, multidetector computed tomography (MDCT) has become the cornerstone of modern emergency departments and trauma centers. In many institutions, MDCT is the de facto diagnostic tool upon trauma activation. In the setting of pelvic imaging, MDCT (with its high spatial resolution and sensitivity as well as short acquisition times) allows for rapid identification and assessment of pelvic hemorrhage leading to faster triage and definitive management. In trauma centers throughout the world, angiography and minimally invasive catheter-based embolization techniques performed by interventional radiologists have become the standard of care for patients with acute pelvic trauma and related multiorgan hemorrhage. In an interdisciplinary setting, embolization may be performed either alone or as an adjunct procedure with open or closed reduction and stabilization techniques. A team-based approach involving multiple disciplines (e.g., radiology, traumatology, orthopedic surgery, intensive care medicine) is crucial to monitor and treat the actively bleeding patient appropriately.

Trauma abdominal penetrante: Revision sistematica de la literatura

Introducción El manejo de las heridas abdominales penetrantes ha variado en los últimos 30 años, la laparotomía mandatoria es la conducta más usada en el Hospital Occidente De Kennedy a pesar presentar complicaciones y aumentar las tasas de morbimortalidad. Existen diferentes conductas selectivas del trauma abdominal penetrante como son: valoraciones físicas seriadas, ultrasonografía, laparoscopia, TAC de triple contraste y lavado peritoneal; sin embargo no se ha definido cuál de estos métodos es el más eficiente para el diagnóstico. El objetivo es determinar cual es el método diagnostico más efectivo para evaluar el trauma abdominal penetrante dependiendo del sitio topográfico de la lesión. Métodos: Revisión sistemática de la literatura en revistas indexadas a nivel mundial y literatura gris colombiana. Se escogieron artículos entre 1990 y 2010 que suministraran la mejor evidencia. Se evaluó su calidad metodológica de acuerdo a las recomendaciones desarrolladas por la Asociación Médica Americana en JAMA 1993. Adicionalmente se utilizó el SCORE de calidad metodológico publicado en la revista Chilena de Cirugía 2003. Los estudios incluidos fueron organizados en una tabla de evidencia donde se tuvo en cuenta los siguientes puntos: fecha de publicación, revista, autor, nivel de evidencia y desenlace principal. Resultados: En total se encontraron 98 artículos, según los criterios de elegibilidad se seleccionaron 57 y se adiciono 2 guías de manejo clínico. A pesar de la heterogeneidad de los estudios se encontró concordancia en 17 artículos en cuanto la disminución de complicaciones, tiempo de estancia hospitalaria y disminución de laparotomías negativas con el uso de la TAC de triple contraste y la laparoscopia diagnostica. Conclusión: No existe un juicio para determinar que metodología diagnóstica es la más eficiente en el manejo conservador, pero resulta evidente que la tendencia actual del manejo del trauma abdominal está dirigida a seleccionar y a enfocar al paciente de forma individual. Las alternativas más efectivas hasta el momento ha considerar son la TAC de triple contraste y la laparoscopia diagnostica en las heridas en flancos, dorso y región toracoabdominal respectivamente.

Mortalidad por trauma cardiaco penetrante en un hospital de Bogotá, Colombia : análisis de factores asociados

Objetivó: Caracterizar los pacientes con heridas cardiacas penetrantes grado II a VI, describir las características del trauma, tratamiento quirúrgico, evolución clínica e identificar los factores asociados a un desenlace. Metodología: Se diseñó un estudio de asociación en 308 pacientes que ingresaron a cirugía con diagnóstico de herida penetrante de corazón entre enero de 1999 y octubre de 2009. Se excluyeron 68 casos. La serie analizada incluyó 240 pacientes con heridas cardiacas. Se analizaron variables demográficas, clínicas, quirúrgicas y de evolución, tabulados en EXCEL® y analizados en SPSS 20®. Resultados: El promedio de edad fue 27.8 años, principalmente hombres (96%), lesiones por arma cortopunzante 93% y un 7% por proyectil arma de fuego. El estado hemodinámico al ingreso (según Ivatury) fue normal 44%; Shock profundo 34%; Agónicos 18% y 3% fatales. El 67% (n=161) presentaron taponamiento cardiaco. Los grados de lesión cardiaca según la clasificación OIS-AAST fueron: grado II 33%, grado III 13%, grado IV 29%, grado V 22% y grado VI 3%. La ventana pericárdica fue el método diagnóstico confirmatorio de lesión en 63% y las incisiones de abordaje quirúrgico fueron la esternotomía 63% y la toracotomía anterolateral 35%. La mortalidad fue 15% (n=36). Las diferencias en mortalidad entre el estado hemodinámico al inicio de cirugía, mecanismo de lesión y grado de herida, demostraron ser estadísticamente significativas (valor de p<0.001). Conclusiones: El estado hemodinámico y las heridas por arma de fuego son factores asociados a mortalidad. La ventana pericárdica subxifoidea favorece la preferencia y buenos resultados de la esternotomía como vía de abordaje quirúrgico.

Management of a complicated crown-root fracture using adhesive fragment reattachment and orthodontic extrusion

Dental trauma is more common in young patients and its sequelae may impair the establishment and accomplishment of an adequate treatment plan. This paper reports a case of complicated crown-root fracture in a young adult that was treated using adhesive tooth fragment reattachment and orthodontic root extrusion. Considering the time elapsed to follow up, the fracture extension, the amount of remaining root portion and the patient's low socioeconomic status, the treatment approach proposed for this case provided good functional and aesthetic outcomes. Clinical and radiographic results after 2 years were successful. This case report demonstrates the importance of establishing a multidisciplinary approach for a successful dental trauma management.
