Background: Approximately one third of all traumatic peripheral artery injuries affect the upper extremities, while two thirds involve the arteries of the lower extremities. Historically, these injuries were treated by open surgical repair. Nowadays, interventional treatment, such as embolization or stent grafting are increasingly used to treat peripheral artery injuries., Objective: Determination of the current state of interventional treatment options for injuries of peripheral arteries., Material and Methods: Selective literature review on the current state of interventional management of peripheral artery injuries., Results: Although scarce, the available data confirm the efficacy of interventional techniques for managing peripheral artery injuries; however, despite improvements in treatment techniques and interventional devices, not all patients are equally well suited for endovascular or open surgical treatment. Consequently, a multidisciplinary decision on the best treatment has to be made on a case by case basis., Conclusion: According to the promising clinical data, interventional treatment should be considered more often. Diagnostic algorithms need to be adapted accordingly., (© 2021. Springer Medizin Verlag GmbH, ein Teil von Springer Nature.)

Introduction: Following the establishment of the first trauma networks in 2009 an almost nationwide certification could be achieved. Despite the impressive number of 46 certified networks, little is known about the actual improvements and the satisfaction of the participating hospitals., Objectives: This article aims to give a first representative overview of the expectations and actual achievements., Material and Methods: An online survey with a total of 36 questions was conducted in 884 hospitals. The questionnaire could be filled out online, sent by post or fax to the AKUT- Office. Descriptive statistical analyses were performed with Microsoft Excel., Results: With 326 responses, a response rate of 48.9% of all active hospitals was achieved. Of the participating hospitals 64.1% (209) were certified and had taken part in the project for an average of 3.9 years. The average score for satisfaction was 2.3, 72.4% (236) felt that there was a need for improvement in the care of severely injured patients and 46.6% (152) in the transfer of patients. In 47.2% (142) no improvement in cooperation with the ambulance service could be determined, 25.2% (82) documented an increase in the number of severely injured patients since participating in the trauma network (TNW-DGU) and 93.9% (306) of all hospitals wanted to participate in the trauma network in the future., Discussion: It could be shown that important goals, such as simplification of patient transfer or general improvement in cooperation have been achieved. Overall there was a high level of satisfaction among the participating hospitals; however, the survey has identified some points which need to be improved by further intensive work.

Background: The number of (seriously) injured children increased again for the first time in 2011. The aim of this study was to analyse differences compared to multiple injured adults and to show the reality of daily treatment., Methods: All cases of the DGU Trauma Registry from the years 1997 to 2010 were examined. The documented cases were divided into different the age groups. The study investigated, e.g. the mechanism of accident, injury pattern, the number of hospital and ICU days, and lethality., Results: At 38.8% the largest percentage of severely injured children and adolescents belongs to the group of 16-17 year olds. The group of 0-5 year olds (15.9%) has the lowest percentage. The most common accident cause was traffic accidents (58.5%). The mechanism of accident and the injury patterns changes with age. Younger patients are often treated in supraregional trauma centers (0-5 year olds: 78.2% vs. 16-17 year olds: 73.1% vs. > 65 years: 63.2%). The average lethality rate was 14.8% (16.3% RISC)., Conclusions: The percentage of severely injured children in the overall population is only 7.4%. Because the majority of patients are primarily treated in supraregional trauma centers, trauma centers with specialisation in paediatric traumatology are mandatory.

Abdominal trauma represents the leading cause of haemorrhagic shock in the severely injured patient and is associated with high mortality and morbidity rates. The trauma surgeon has a central role in the multidisciplinary team addressing the specific diagnostic and therapeutic needs of patients with abdominal trauma. The management of blunt and penetrating abdominal trauma has undergone substantial changes in recent decades. Major innovations have been established in the field of diagnostic imaging and of nonoperative interventions such as angioembolization and endoscopic procedures. Another key development is the introduction of the damage control concept for the care of patients with abdominal trauma. The present manuscript comprises a review of the current management of abdominal trauma with an emphasis on diagnostic and therapeutic innovations.

In Germany, approximately 35,000 patients with major injuries are treated per year. The treatment of patients suffering from major injuries is both a medical and a logistic challenge. Despite the high-level quality of medical care, regional differences exist due to geographical and infrastructural conditions. In addition, discrepancies in human resources and technical equipment in hospitals influence diagnostics and treatment of severely injured patients. Based on these findings trauma networks of the German Trauma Association were founded to guarantee nationwide high-quality medical care of these patients. This article provides an overview about requirements of all involved professions and establishment of trauma networks considering state-of-the-art communication technology. Moreover, characteristics of the auditing and certification process and planning of the integration of rehabilitation facilities are described.

Introduction: Femoral fractures are common injuries in multiple trauma patients. The treatment concept of damage control orthopedics (DCO) is in competition with the concept of early total care (ETC)., Patients and Methods: In a retrospective study (2003-2007) 73 multiple trauma patients with femoral shaft fractures were included. The cohort was subdivided according to the Injury Severity Score (ISS) (16-24, 25-39 and more than 40) and treatment strategy (ETC versus DCO). Patients were analyzed for outcome and cost aspects., Results: In the patient group with an ISS 16-24 ventilation time and intensive care treatment were longer after DCO treatment, overall costs and deficient cost cover were higher in the DCO group. In the patient group with an ISS 25-39 cost aspects showed a higher cover deficient in the DCO group., Conclusion: From an economic point of view the cost deficits for the ETC group were lower than in the DCO group. The treatment strategy should be selected by the pattern of injuries. The costs should be addressed by the Institute for the Hospital Remuneration System (INEK).

Injuries of great vessels, such as the subclavian or vertebral arteries in childhood are rare. More frequent and therefore better described are dissections of the vertebral artery, which frequently occur following low energy trauma. The combination of dissection of the vertebral and subclavian arteries described in this case study led to sensory affections of the left arm. Therapeutic anticoagulation is the therapy of choice to avoid possible ischemic insults. The therapeutic approach of injuries to the subclavian artery remains unclear and is in the focus of discussions.

Background: The mechanism of injury is the major cause for trauma team activation and emergency room resuscitation of trauma victims. To date, it remains unclear to what extent the injury mechanism influences injury pattern and severity., Methods: A comprehensive systematic literature search based on Medline was carried out., Results: Only a limited number of studies are available which investigated the influence of injury mechanisms on injury patterns and severity. There are no specific mechanisms for traumatic brain and spine injuries. Injuries to the chest and abdomen most frequently resulted from motor vehicle accidents involving passengers sitting on the side of the impact. Steering wheel deformity correlated with the injury severity. Pelvic fractures occurred most frequently due to motor vehicle accidents. The highest mortality resulted from pedestrians being struck by a vehicle and additional loss of life in the same vehicle compartment., Conclusions: The systematic literature research showed inconsistent results regarding the influence of trauma mechanisms on the resulting injury. Therefore, a treatment algorithm for trauma patients should be independent of the mechanism which is represented in several training programs (e.g. ATLS and PHTLS). However, the mechanism of injury may increase the alertness of the trauma team with respect to injury distribution and severity.

Multiple trauma patients frequently demonstrate a hypothermic core temperature, defined as a temperature below 35 degrees C, already at admission in the emergency room. As a drop of the core temperature below 34 degrees C has been shown to be associated with a significant increase in post-traumatic complications, this limit is considered to be critical in these patients. Multiple trauma patients with hypothermia demonstrate a markedly increased mortality rate compared to normothermic patients with the same injury severity. Therefore effective rewarming measures are essential for adequate bleeding control and successful resuscitation. If and to what extent the induction of controlled hypothermia in the early phase of treatment on the intensive care unit after resuscitation and operative bleeding control can contribute to an improved post-traumatic outcome, has to be clarified in further experimental and clinical studies.

Background: The German Association of Trauma Surgery has developed a concept for the quality-assured care of severely injured patients; this concept includes the establishment of trauma networks. In this study, hospitals and emergency services in Lower Saxony were asked about their demands on the Hannover regional trauma network., Materials and Methods: Trauma departments in Lower Saxony and adjoining federal states were asked to self-assess their level of trauma care. The demands of emergency services and trauma departments on the trauma network were also ascertained., Results: Responses to the questionnaire were received from 70.2% of trauma departments and 11.5% of emergency services organizations. Of these, 46.9% of the trauma departments classified themselves as a "center of basic care", 50.0% as a "regional trauma center", and 3.1% as a "national trauma center". Compared with the regional trauma centers, centers of basic care requested fast transfers of patients to a trauma center significantly more often, whereas trauma centers desired more educational activities., Conclusion: The demands of trauma centers on a trauma network correspond with the aims formulated by the German Association of Trauma Surgery. These demands depend on the level of trauma care provided. Close cooperation with emergency services is essential to strengthen collaboration within the trauma network.

Due to their excellent osteoinductive, osteogenetic, and osteoconductive properties, autologous bone grafts possess biomechanical advantages over synthetic bone substitutes. Furthermore, unlike cadaveric allografts and xenografts, they carry no risk of immunogenic response or transmission of infectious diseases. However, the limited availability of autologous bone grafts requires the use of the above-mentioned bone substitutes for management of large bone defects. The"Reamer-Irrigator-Aspirator-" (RIA-)technique may present an alternative method for harvesting a larger volume of autologous bone graft as compared with conventional harvesting procedures. We report on intramedullary reaming by the RIA technique to obtain autologous bone graft for a nonunion of the proximal femur. The contralateral femur was reamed and the bone graft was applied to the nonunion. The patient showed clinical and radiological healing of the nonunion without donor site complications.

The incidence of gunshot wounds is increasing also in Europe and surgeons in urban trauma centers are more frequently confronted with this type of injury. Since there is no established treatment algorithm for gunshot injuries to the extremities, the surgeon should rely on established soft tissue injury and fracture protocols. Gunshot fractures with minor soft tissue destruction should be treated as closed fractures. The treatment of choice for unstable fractures is early internal stabilization, whereas stable fractures may be treated by functional bracing. The administration of an antibiotic prophylaxis for fractures with minor soft tissue injury is controversial. Gunshot fractures with major soft tissue injury should be treated as open fractures. Debridement of nonviable tissue and external fixation are recommended. Prophylactic intravenous antibiotics are mandatory and prophylactic fasciotomy is often required. Upon definitive internal stabilization, bone grafting should be considered since gunshot fractures are usually associated with a high degree of comminution. Articular gunshot injuries are treated as open joint injuries and require irrigation, debridement, foreign body removal and antibiotic prophylaxis.

Background: Thirty years after its introduction in Germany, the benefits of the helicopter emergency medical service (HEMS) compared to ground ambulances (GA) still remain unclear. The aim of this study was to evaluate the influence of helicopter transport on rescue time and mortality based on the data of the German Trauma Registry., Methods: Data from patients with multiple injuries were documented prospectively between 1993 and 2003 in different trauma centers in Germany, Switzerland, Austria and The Netherlands. From these data, patients with an injury severity score (ISS)<16 were excluded. Patients who were transported to the hospital without a physician were also excluded. The data from included patients were evaluated for time to hospital and influence of transportation service on mortality., Results: A total of 7,534 patients with multiple injuries were included. Of these, 3,870 patients were transported by HEMS and 3,664 reached the hospital by GA. There were 74.9% male patients in the HEMS group, and 71.3% male patients in the GA group. The mean ISS was higher in the HEMS group (31.4 vs 30.7; P<0.01); patients transported by GA were older (HEMS: 39.2; NEF:41.3; P<0.01). The GA arrived on the scene after 14.33 min, the HEMS after 18.18 min (P<0.01). Time at the scene was longer in the HEMS group (HEMS: 26:26 min; NEF: 22:29 min; P<0.01). Intubation rate in the HEMS group was about 80%, while patients transported by GA were intubated in 60% of cases. The overall mortality was 30.9%. Evaluation of the TRISS prediction of survival showed a benefit for patients transported with HEMS. In a multivariate analysis, intubated patients with ISS

In polytraumatized patients severe joint injuries represent a special entity because their management is complex and lengthy. The surgeon must decide if limb salvage is indicated and which further surgical steps have to be instituted. The decision for amputation is based on the patient's general condition and the soft-tissue and neurovascular injury. Scoring systems are useful for decision making. Limb salvage is associated with a multistage surgical approach. Priority is given to restoration of sufficient blood supply and soft tissue repair; the indication for fasciotomy covers a wide field. To avoid further compromise to soft tissue and perfusion, temporary joint and fracture stabilization is required. Definitive surgery has to be delayed until the 2 week period, starting between the fifth and tenth day after trauma.

While tetanus is a rare disease in industrialized countries, this infectious disease is still responsible for up to 1,000,000 deaths per year in the developing world. In Germany, the introduction of a country-wide vaccination program (STIKO) has led to a decrease in the frequency of tetanus infection from 115 cases per year in the 1960s to fewer than 15 cases per year in the years from 1990 to 2000. In spite of all the treatment now available, tetanus infection still has a lethal outcome in up to 40% of cases. The Robert-Koch Institute recommends active or passive vaccination depending on the wound classification and the patient's current vaccination status. Since when patients have multiple trauma the emphasis while they are being treated for shock is on stabilisation and diagnosis, there is a real risk of underestimating the size and the level of contamination of existing wounds. Since it is not possible to ascertain the patient's vaccination status in most cases, we recommend simultaneous immunization of polytraumatized patients with skin lesions using Tetanol-Tetagam early in the course of the diagnostic procedures while the patients are still in the emergency room.
