Background: In order to continue to efficiently provide both personnel-intensive and resource-intensive care to severely injured patients, some hospitals have introduced individually differentiated systems for resuscitation room treatment. The aim of this study was to evaluate the concept of the A and B classifications in terms of practicability, indications, and potential complications at a national trauma center in Bavaria.

Methods: In a retrospective study, data from resuscitation room trauma patients in the year 2020 were collected. The assignment to A and B was made by the prehospital emergency physician. Parameters such as the injury severity score (ISS), Glasgow outcome scale (GOS), upgrade rate, and the indication criteria according to the S3 guidelines were recorded. Statistical data comparisons were made using t‑tests, χ²-tests, or Mann-Whitney U‑tests.

Results: A total of 879 resuscitation room treatments (A 473, B 406) met the inclusion criteria. It was found that 94.5% of resuscitation room A cases had physician accompaniment, compared to 48% in resuscitation room B assignments. In addition to significantly lower ISS scores (4.1 vs. 13.9), 29.8% of B patients did not meet the treatment criteria defined in the S3 guidelines. With a low upgrade rate of 4.9%, 98% of B patients had a GOS score of 4 or 5.

Conclusion: The presented categorization is an effective and safe way to manage the increasing number of resuscitation room alerts in a resource-optimized manner.

Background: The correct diagnosis and treatment of the atlanto-occipital dislocation (AOD) remains a major challenge.

Objective: To evaluate the different radiological diagnostic criteria for AOD and discuss potential treatment strategies based on a case with AOD and additional fracture of the atlas.

Material and methods: A 29-year-old male patient is presented who suffered from AOD with concomitant fracture of the anterior and posterior arches of the atlas with rotational atlantoaxial dislocation following an accident in forestry. The following parameters were evaluated for the diagnosis and assessment of postoperative reduction: Powers ratio, the X‑lines-method, Wackenheim line, basion-dens interval (BDI), basion-axial interval (BAI) and occipital condyle-C1 interval (CCI).

Results: Stabilization was performed by occipitocervical spondylodesis from C0 to C2/3. For final reduction it was necessary to reduce the malrotation of the atlas. In the presented case, the revised CCI proved to be a sensitive and valid yet practical parameter. Powers' ratio and the BDI were less suited for assessing the diagnosis. The X‑lines-method, Wackenheim line and the BAI did not adequately detect the pathological situation.

Discussion: The AOD is a severe injury requiring immediate correct diagnosis for later adequate treatment results. Among the published parameters, the revised CCI proved to be a practical and valid parameter to detect AOD. For definitive treatment, the operative occipitocervical stabilization is regarded as the method of choice.

Background: Both in Germany and internationally there is a vehement controversy about the appropriate time for care of proximal femoral fractures in older patients. The effort to achieve high quality and uniform standards of care culminated in the German healthcare system in the strict requirement of delay-free surgery within 24 h. Until now, in view of their high vulnerability patients who were severely injured were too often operated on late with the reference to a general medical condition that could be improved preoperatively. In particular, the fear of complications due to a pre-existing long-term anticoagulation treatment was repeatedly emphasized.

Objective: The present study is dedicated to the question of whether a delay in surgery of anticoagulated patients with proximal femoral fractures already during the inpatient course has a detrimental effect on the complication statistics and the mortality of the patients. The extent to which external quality assurance data are suitable for rebutting any objections to an operation as soon as possible are examined.

Material and methods: The study is based on treatment data from the external inpatient quality assurance procedure of the federal state of North Rhine-Westphalia from the years 2018-2020. Patients with a proximal femoral fracture were considered. This includes femoral neck fractures and fractures in the area of the pertrochanteric to subtrochanteric region. Only cases with joint-preserving fracture care were selected. The data sets were analyzed using suitable statistical software.

Results: More general complications and deaths have been observed in anticoagulated patients. The trend of delayed fracture treatment under anticoagulant medication continues to be clearly visible. A positive association between longer preoperative waiting time and undesirable courses can be confirmed.

Conclusion: With respect to fracture care when taking anticoagulants, it must be critically examined to what extent a rapid normalization of the coagulation situation is necessary and this actually improves the chances of low complication courses. Should the elimination of the anticoagulant effect by substitution or antidote appear necessary, this should not prevent early care.

Fractures of the tibial pilon are severe injuries which can be accompanied by articular impaction, comminution and soft tissue injury. Soft tissue injury with already existing skin damage can further complicate the method of treatment. In these cases, the method of unilateral or circular external fixation can be used as an alternative method of treatment. Minimally invasive percutaneous osteosynthesis with spanning rigid and dynamic unilateral external fixation as a one-stage method has been used for the treatment of intra-articular pilon fractures. We report a case of a patient with an intra-articular pilon fracture with chronic venous insufficiency and venous ulcer, who was injured after falling from a height and who had emergency surgery based on capsuloligamentotaxis and percutaneous osteosynthesis with a spanning unilateral external fixator. The patient was mobilized postoperatively for walking without weight bearing on the injured leg. The initial rigid spanning external fixation was transformed into dynamic fixation to enable ankle joint movements 8 weeks after surgery. The external fixator was removed 4.5 months after surgery and the Kirschner wire and screws were removed 7 months after surgery. The final functional result 1 year after the injury was good and motion of upper ankle joint was moderately restricted without pain. Swelling occurred after walking for longer distances.

The impact of energy on the thorax can lead to serial rib fractures, sternal fractures, the combination of both and to injury of intrathoracic organs depending on the type, localization and intensity. Sometimes this results in chest wall instability with severe impairment of the respiratory mechanics. In the last decade the importance of surgical chest wall reconstruction in cases of chest wall instability has greatly increased. The evidence for a surgical approach has in the meantime been supported by prospective randomized multicenter studies, multiple retrospective data analyses and meta-analyses based on these studies, including a Cochrane review. The assessment of form and severity of the trauma and the degree of impairment of the respiratory mechanism are the basis for a structured decision on an extended conservative or surgical reconstructive strategy as well as the timing, type and extent of the operation. The morbidity (rate of pneumonia, duration of intensive care unit stay and mechanical ventilation) and fatality can be reduced by a timely surgery within 72 h after trauma. In this article the already established and evidence-based algorithms for surgical chest wall reconstruction are discussed in the context of the current evidence.

In the majority of cases implosion injuries to the thoracic wall are caused by blunt, massive force acting on the thorax. Basically, different regions and directions of the acting energy have to be taken into account. In common usage, the term implosion injury has become established, especially for the sequelae of lateral energy impact. Particular attention should be paid to the stability of the shoulder girdle, the underlying hemithorax and its intrathoracic organs.

Background/objective: In 2020 the COVID-19 pandemic posed a major challenge to the healthcare system. The hypothesis is that the COVID-19 pandemic in 2020 had an impact on the care of older adults with proximal femoral fractures due to resource scarcity, regardless of whether or not the patient was infected.

Material and methods: This study analyzed the data of 87 hospitals which entered 15,289 patients in the Geriatric Trauma Register ("AltersTraumaRegister DGU®", ATR-DGU) in Germany in 2019 and 2020. In this study we analyzed the influence of the COVID-19 pandemic on the inpatient treatment of hip fractures as well as the mid-term follow-up during the first 120 days. For the main analysis, we compared patients documented during the COVID-19 pandemic in 2020 (April-December) with a control group in 2019 (April-December). Additionally, we performed a subgroup analysis of the periods with high COVID-19 incidence rates.

Results: Between 2019 and 2020 a total of 11,669 patients (2020: n = 6002 patients vs. 2019: n = 5667 patients) were included in this study. Only minor differences were found between the patients treated during the pandemic; however, when the COVID-19 incidence in Germany was greater than 50/100,000 residents, significantly fewer patients (p < 0.001) were discharged to a geriatric rehabilitation ward (27.2% vs. 36.3%) and an increased mortality rate during inpatient treatment was determined (8.4% vs. 4.6%) (p < 0.001).

Discussion: The healthcare system was able to respond to the pandemic and patients' clinical courses were not impaired as long as the incidences were low. Nevertheless, the healthcare system reached its limits in times of higher incidence, which was also directly reflected in the patient outcome, mortality and place of discharge.

Background: Thoracic trauma is a frequent injury in the routine treatment of injured patients. Due to the increasing demographic changes a further increase is to be expected, especially after low-energy trauma.

Objective: Expected complications after conservative vs. operative treatment of various injury patterns of thoracic trauma.

Material and methods: Evaluation of a selective literature search regarding possible complications after thoracic trauma and formulation of instructions for action as expert recommendations.

Conclusion: Both conservative and operative treatment of thoracic trauma have their specific complications, which have to be known to the treating physician. Lung contusions are often underestimated in the initial radiological diagnostics but often lead to relevant problems during the further course of treatment. After conservative treatment of rib fractures persistent pain, functional limitations or even relevant deformities due to secondary dislocation, can remain. There is a significant risk of overlooking or underestimating relevant injuries during the initial diagnostics which then leads to secondary complications. By far the most frequent risk of surgical treatment is an incorrect positioning of chest tubes. Overall, postoperative infections after chest trauma are relatively rare.
