Current Trends in Orthopaedics and Trauma in Germany.

During the Guest Nation Symposium (cobranded with the Deutsche Gesellschaft für Orthopädie und Unfallchirurgie, Deutsche Gesellschaft für Orthopädie und Orthopädische Chirurgie, and Deutsche Gesellschaft für Unfallchirurgie) at the 2023 American Academy of Orthopaedic Surgeons Congress in Las Vegas, the goal was to compile nationally important content from German orthopaedics and trauma surgery. This resulted in a mix of content on the latest developments in trauma care, knee arthroplasty, spinopelvic importance for hip arthroplasty, stemless shoulder endoprostheses, joint preservation for ankle osteoarthritis, trauma education, and research. Of course, this is only a small selection of the important issues that are being driven forward in Germany.

[National challenges for trauma surgery in Germany due to violence and war]. / Nationale Herausforderungen für die Unfallchirurgie in Deutschland bei Gewalt und Krieg.

Due to the war in Ukraine and the treatment of patients with war wounds in the hospitals of the TraumaNetworks of the German Society for Trauma Surgery (TraumaNetzwerke DGU®), injuries from life-threatening mission situations (LebEL), terrorism, violence and war have become a matter of daily professional life. Furthermore, the societal and global feeling of security has fundamentally changed. The much-cited term "turning point in history", the reorientation of the Armed Forces and the investigation of the resilience of the healthcare system with respect to the "fitness for war", approximate to the description of the current challenges for trauma surgery (UCH) in Germany. Based on the developments following the terrorist attacks in Paris in 2015 and in Brussels in 2016, a clarification is given as to which adaptations have already been successful and how quickly an improvement could successfully be achieved. In this context, the concept of tactical care and the course on Terror and Disaster Surgical Care (TDSC), for example, have been game changing. The main challenge currently lies in overcoming the structural alterations in the German healthcare system and professionally in the treatment of war wounded personnel from Ukraine. The knowledge gained from these two national tasks must be analyzed for the future development and adaptation of established treatment structures, e.g., of the TraumaNetzwerke DGU®, under the requirements of the increased resilience against war, terrorism and violence. The aim is to name that which has already been achieved with respect to the national challenges for UCH and at the same time to outline or discuss further necessities for improvements and elimination of possible gaps in capabilities.

[Initial in-hospital treatment of patients with penetrating trauma due to violence and war]. / Innerklinische Erstversorgung von Patienten mit penetrierendem Trauma nach Gewalt und Krieg.

BACKGROUND: Current political and social developments have brought the topics of violence, in this context attributable to terrorism and sabotage, and since February 2022 awareness of war in particular has again greatly increased. This article aims to present the contextualized dealing with penetrating injuries in terms of initial in-hospital treatment. OBJECTIVE: The question remains to be answered as to what extent penetrating injuries require special attention and to what extent the treatment priorities, options and strategies as well as surgical treatment require adaptation of the usual approach in routine clinical practice in Germany. MATERIAL AND METHOD: The experience of the authors in this field from military operations in Afghanistan, Iraq, the Republic of Mali, Kosovo and Georgia as well as the core content of the Terror and Disaster Surgical Care (TDSC®) course on this topic, have been contextualized and incorporated. In addition, aspects of a comprehensive systematic literature review and current data from a national evaluation on the topic of preparing hospitals in Germany for such scenarios are taken into account. RESULTS AND DISCUSSION: The clinical systems need to be well-prepared for such casualties, especially if they require treatment in large numbers. This is precisely so because the majority of patients are in a relevantly threatening situation (usually in the sense of a hemorrhage), treatment must be very urgently provided and in such scenarios a lack of resources must always be overcome, at least temporarily, especially for example for blood transfusions.

[Treatment of the wounded from the war in Ukraine in the trauma networks of the DGU-Requirement, reality and motivation over the course of 18 months ]. / Versorgung von Kriegsverletzten aus der Ukraine in den Traumanetzwerken der DGU ­ Anspruch, Wirklichkeit und Motivation im Verlauf von 18 Monaten .

BACKGROUND: The war in Ukraine and the medical treatment of the wounded in hospitals in Germany has now represented a challenge for more than 15 months. The majority of trauma patients were distributed via the general holding center (GMLZ) at the Federal Office of Civil Protection and Disaster Assistance (BBK) by the cloverleaf concept and the trauma networks. Initially, numerous offers of assistance were promoted with great solidarity. For documentation of the current motivation situation and also for identification of the potential for improvement, a 2-stage survey of senior physicians in the organized and certified hospitals in the trauma networks was carried out. MATERIAL AND METHODS: An online survey of senior physicians of the trauma network hospitals was carried out with a semistructured written questionnaire in December 2022 and a follow-up survey during the Trauma Network Meeting (TNT) Congress in September 2023 in Frankfurt. RESULTS: Of the questionnaires 113 could be evaluated in December 2022 and 70 completed questionnaires in September 2023. The answers came from national trauma centers (ÜTZ), regional trauma centers (RTZ) and local trauma centers (LTZ) each with approximately one third. On average 2.7 patients were treated in all participating hospitals up to December and up to September no more than 5 in more than half of the hospitals overall. The main challenges for all participants at both points in time were the long hospital stay, the demanding pathogen status and sometimes unclarified or not completely covered reimbursement of costs. Nevertheless, more than 80% of the specialist departments received backing from their hospital sponsors as well as their personnel for the continuing treatment of the wounded from Ukraine. CONCLUSION: The medical and professional challenges in the treatment of the wounded from Ukraine are, as expected, characterized by the demanding injury patterns of the musculoskeletal system and the colonization with multidrug-resistant pathogens. This results in a long course of treatment, where the remuneration does not always cover the costs. Despite these challenges the solidarity in the hospitals of the trauma networks is unbroken. Simultaneously, there are numerous possibilities for improvement in order to enhance the prerequisites for future comparable humanitarian assistance jointly with politics.

[Microbiological challenges in the treatment of war injuries]. / Mikrobiologische Herausforderungen bei der Versorgung von Kriegsverletzungen.

The treatment of war injuries represents a continuing and recurrent challenge in modern reconstructive surgery. Previously, tumor resections and sepsis-related resections were mainly responsible for lengthy bone defects in Germany. In recent years another picture has increasingly emerged, particularly caused by the medical support of Ukraine. Aspects of military surgery are also becoming more important in civil hospitals, especially in the treatment of gunshot and explosion injuries. In Germany, war injuries are currently secondarily treated, as the distribution of patients is carried out according to the cloverleaf principle, weeks or months after the occurrence of the primary injury. In addition to complex bone and soft tissue defects of the extremities following such injuries, which often affect neural and vascular structures, reconstruction is often complicated by an increasing spectrum of multidrug-resistant pathogens. The definition of microbiological terms, such as contamination, colonization, critical colonization, local and systemic infections are important in the clinical routine in order to initiate a targeted treatment, especially in treatment with antibiotics. Wound swabs for determination of the spectrum of pathogens and the optimal testing of resistance are important for selecting the appropriate antibiotic agents. The concept of antibiotic stewardship (ABS) is established in many hospitals to improve the quality of antibiotic treatment and to minimize the formation of resistance. The selection of the method of reconstruction depends on the condition of the patient, the overall clinical constellation and the function to be expected after completion of treatment. The treatment of injuries due to violence and terrorism necessitates clear concepts and an interdisciplinary approach, especially with respect to microbiological challenges and increasing resistance situations.

Improved gait parameters following surgical revascularization in patients with intermittent claudication.

Objective: Intermittent claudication (IC) is known to be associated with impaired gait parameters, with a higher incidence of falls and higher oxygen consumption due to uneconomic walking. However, the influence of arterial disobliteration in patients with IC on their gait pattern has rarely been investigated to date. The aim of this study was to examine the gait patterns before and after inflow revascularization by surgical disobliteration of pelvic and inguinal arteries (ie, common iliac artery, external iliac artery, common femoral artery, profound femoral artery, superficial femoral artery) in IC patients. Successful surgical disobliteration of inflow arteries (improvement of ankle brachial pressure index of ≥0.2 and patent common iliac, external iliac, common femoral, profound femoral, and superficial femoral arteries) is known to improve the painless walking distance for patients with IC due to peripheral arterial disease; however, its influence on gait parameters is unclear. We hypothesized that the gait parameters would also improve after surgery. Improved gait parameters can lead to a more economic walking process, lower oxygen consumption, a lower risk of falls, and a higher quality of life. Methods: In a single-center, exploratory, longitudinal study, we examined the gait parameters of 20 IC inpatients of our hospital before and after surgical disobliteration of pelvic and inguinal arteries. Spatiotemporal parameters such as range of motion of the hip and knee joint, stance phase, cadence, and foot rotation were obtained using the Diers 4Dmotion Lab (Diers International). The gait parameters were obtained under painful walking conditions preoperatively and with the patients walking pain free at the same speed postoperatively. Results: A total of 20 patients were examined. Surgical revascularization led to a higher walking cadence (mean, plus 7.88 steps; 95.5 steps/min vs 87.6 steps/min; P = .024), an increased range of motion of the hip joint (mean, plus 2.0°; 35.1° vs 33.1°; P = .038), and improved foot rotation (mean, plus 2.0°; 11.0° vs 9.0°; P = .02). Regarding other parameters such as step length, stance phase, and step duration, smaller differences were detected in this study. Conclusions: In this exploratory study, we found that surgical revascularization of pelvic and inguinal arteries in IC patients improved certain gait parameters. Further studies with larger patient numbers are needed to confirm these data and provide more evidence on this subject.

[Challenge of limb care after violence and war with a special focus on imaging procedures]. / Herausforderung der Extremitätenversorgung nach Gewalt und Krieg mit besonderer Betrachtung bildgebender Verfahren.

BACKGROUND: Injury patterns in the area of the extremities following violence and war harbor many special features and require special attention. Destructive and complex defect injuries are often present, which necessitate elaborate and special reconstruction approaches, predominantly as part of a staged and multistaged procedure. RESEARCH QUESTION: In this context, special attention must be paid to the diagnostic options as an essential aspect, as a clear diagnosis means that targeted treatment steps can be planned and implemented. MATERIAL AND METHOD: The authors' experience in this field from military operations in Afghanistan, Iraq, the Republic of Mali, Kosovo and Georgia, as well as the core content of the Terror and Disaster Surgical Care (TDSC®) course on this topic, have been contextualized and incorporated. In addition, aspects of interdisciplinary cooperation with radiological and, in particular, nuclear medicine disciplines are taken into account in the daily routine. RESULTS AND DISCUSSION: Extremity injuries in the context of violence and war are accompanied by complex bone and surrounding soft tissue defects due to the high energy impact. The principles of reconstruction familiar from everyday life can only be transferred one-to-one to a limited extent. The treatment pathways are often very long and complex and the questions of infection and tissue vitality must be answered again and again in stages. Interdisciplinary collaboration with the disciplines specialized in imaging procedures, particularly in the field of nuclear medicine, is one of the key building blocks for a successful treatment pathway.
