After conservative treatment nonunion (pseudarthrosis) of the clavicle can be observed approximately 10 times more frequently (15-24%) than after surgical treatment (1.4%). Risk factors include the fracture location, displacement, fracture type, sex, the severity of the accident and refractures. The diagnosis of pseudarthrosis of the clavicle can be made by a thorough medical history, clinical examination and imaging procedures. The main symptom is pain, often accompanied by malalignment, instability, neurological symptoms and restricted mobility of the affected shoulder. The diagnosis is confirmed by X‑ray images and, if necessary, a computed tomography (CT) scan. Pseudoarthrosis is classified according to the morphological appearance in X‑ray images and the cause. A differentiation is made between vital and nonvital pseudarthroses. Only symptomatic pseudarthrosis requires treatment. Nonoperative methods, such as magnetic field therapy or ultrasound are minimally effective. Surgical interventions are indicated for pain, movement restrictions or neurovascular problems. The goals of surgical treatment are to restore the vitality, bone length and stability through angular stable osteosynthesis. In cases of surgical pretreatment the anteroinferior plate position offers a good alternative to the superior plate position. In some cases double plating osteosynthesis can be indicated. Autogenous bone material, allogeneic substitute material and vascularized grafts are used for bony defects. Surgical treatment shows high rates of healing but also carries an increased risk of infection.

Bite injuries require differentiated treatment due to the deeply inoculated polymicrobial pathogen spectrum, possible concomitant injuries and pronounced soft tissue damage. Dog bites are the most common bite injuries but are less complicated to heal than human and cat bites. The location of the bite greatly depends on the age and the size of the bite victim as well as the type of bite perpetrator. In every case detection of the pathogen should be carried out to provide the best possible adapted treatment in the event of an exacerbation. The primary antibiotic treatment should be empirical with amoxicillin + clavulanic acid or ampicillin + sulbactam and, if necessary, adjusted according to the antibiogram. Depending on the findings, surgical treatment includes excision of the bite canal and a customized wound debridement. It is important to check the vaccination status of those involved and if indicated, to carry out postexposure prophylaxis for tetanus and rabies.

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.

Traumatic posterior atlantoaxial dislocation (PAAD) without detection of a fracture of the upper cervical spine is a very rare injury that usually occurs in younger patients and in most cases leads to immediate death due to distraction of the spinal cord. In contrast, the present case describes this injury in a female geriatric patient at the age of 75 years. In the literature there are also clinical case reports, where traumatic PAAD without a fracture did not result in neurological deficits and where initially existing neurological deficits were completely reversible through closed or open reduction and internal fixation.

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.

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.

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.

Background: Proximal humeral fractures are a relatively common injury in childhood and adolescence, accounting for 0.45-2% of all fractures [2, 18]. Treatment is usually conservative but is still the subject of a scientific debate [9, 12]. In addition to the S1-LL, there are different recommendations for the diagnostics and treatment of these fractures in the literature.

Methodology: As part of the 10th scientific meeting of the SKT of the DGU, the existing recommendations and the relevant or current literature were critically discussed by a panel of experts and a consensus was formulated. An algorithm for the diagnostics, therapy and treatment was integrated into this.

Results: The measurement of axial deviation and tilt is not interobserver and intraobserver reliable [3]. The age limit for when complete correction is possible was set at an age of 10 years, as the correction potential changes around this age. For diagnostic purposes, well-centered X‑ray images in 2 planes (true AP and Y‑images without thoracic parts) is defined as the standard. At the age of less than 10 years, any malposition can be treated conservatively with Gilchrist bandaging for 2-3 weeks. Surgery can only be indicated in individual cases, e.g., in the event of severe pain or the need for rapid weight bearing. An ad latus displacement of more than half the shaft width should not be tolerated over the age of 10 years. Due to the variance in the measurement results, it is not possible to recommend surgical treatment depending on the extent of the ad axim dislocation. As a guideline, the greater the dislocation and the closer the child is to growth joint closure, the more likely surgical treatment is indicated. The development should be taken into account. The gold standard is retrograde, radial and unilateral ESIN osteosynthesis using two intramedullary nails. Osteosynthesis does not require immobilization. A follow-up X‑ray is planned for unstable fractures without osteosynthesis after 1 week, otherwise optional for documentation of consolidation after 4-6 weeks, e.g., if sports clearance is to be granted and before metal removal (12 weeks).

Conclusion: Recommendations for surgical indications based on the extent of tilt are not reproducible and seem difficult in view of the current literature [3, 9, 12]. A pragmatic approach is recommended. The prognosis of the fracture appears to be so good, taking the algorithm into account, that restitutio ad integrum can be expected in most cases.

The case of a 43-year-old male patient is described, who suffered several injuries due to a traffic accident, including a distraction injury to the thoracic spine. A specific feature of this case was the existing spondylodesis with material fracture and secondary loss of reduction. Due to this, the guidewires of the pedicle screws were placed in a navigation pattern in the absence of adjustable pedicles and an abnormal screw corridor. This guarantees an optimal positioning with associated patient safety.
