Abstract
BACKGROUND AND OBJECTIVE Every year in Germany over 100,000 people, mostly of older age, suffer a proximal femoral fracture. Increasing case numbers in connection with an aging population and a relatively large number of concomitant diseases requiring treatment make everyday care more difficult. It is therefore of great importance to observe the quality of care for these patients using relevant quality parameters in order to be able to derive implications for everyday treatment practice. MATERIAL AND METHODS The data of the external inpatient quality assurance from North Rhine-Westphalia for the years 2007-2008 and 2017-2018 were analyzed and the time periods compared. In addition, based on the documented secondary diagnosis and other influencing parameters, a risk adjustment was carried out with the aid of a logistic regression model with respect to the outcomes of general and surgical complications and mortality. Both osteosynthetically and endoprosthetically treated patients were taken into account. A total of 61,249 cases were included in the study. RESULTS Positive developments could be observed in the area of surgical complications and wound infections with decreases of 1.2% and 0.8%, respectively. Patients with cardiovascular diseases had a particularly poor outcome. Here, improvements in the subcategory of cardiovascular events were found for general complications. The mortality remained unchanged at 6%. Operative activity on the weekends increased significantly. Patients whose hospital admission was related to the weekend did not show an increased risk of complications or mortality. Although the proportion of patients who were operated on after more than 48 h was reduced from 11.4% to 8.2%, the operation (> 24 h) was still delayed in 26.8% of cases. CONCLUSION Against the background of increasing performance demands on the healthcare system, the results document improvements in some central areas of inpatient treatment. Nevertheless, the development of strategies for the further reduction of the preoperative waiting times in a medically justifiable manner is required. Internal concomitant diseases have a decisive influence on patient outcome. Thus, an adequate treatment of the multimorbid patient collective is to be established in everyday practice on the basis of close cooperation between geriatric traumatology and geriatric internal medicine departments.

Abstract
BACKGROUND The medical challenges caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV‑2) pose a tremendous burden on the healthcare system. This study aimed to analyze the effects of a SARS-CoV‑2 infections or disease progression on inpatient mortality of geriatric patients after proximal femoral fracture surgery. METHODS A retrospective analysis was conducted in all patients with a proximal femoral fracture surgically treated in an urban regional trauma center from 01/01/2020 to 01/31/2021. According to PCR test results detecting SARS-CoV‑2, the patients were divided into two groups (SARS-CoV‑2 positive vs. SARS-CoV‑2 negative). Patient data, disease progression data, and treatment-related information were evaluated for all patients. Statistical data analysis was performed using unpaired Student's t test or non-parametric Mann-Whitney U test. RESULTS A total of 311 patients (women: 70.4%, age: 82.0 ± 11.0 years) were included in this study. Of these 3.9% (12/311) had a positive test result for SARS-CoV‑2. Significantly more deceased patients were found in the group tested positive for SARS-CoV‑2 (SARS-CoV‑2 positive: 41.7%, SARS-CoV‑2 negative: 5.4%, p < 0.001). In addition, the number of proximal femoral fracture associated deaths correlated with the number of positive test results performed in the Clinic. The length of stay of SARS-CoV‑2 COVID-19 survivors tended to be greater than in those who were tested negative (SARS-CoV‑2 COVID-19 positive: 15.6 ± 13.1 days, SARS-CoV‑2 COVID-19 negative: 11.5 ± 6.5 days, p = 0.683). Furthermore, a significant difference in age was found in SARS-CoV‑2 survivors and SARS-CoV‑2 decedents (deceased: 95.5 ± 7.5 years, alive: 83.5 ± 7.3 years, p = 0.020). CONCLUSION The study was conducted before the introduction of SARS-CoV‑2 vaccination. The results therefore refer to immune naive (unvaccinated) patients. In our study, more than 40% of all patients with proximal femoral fractures who tested positive for SARS-CoV‑2 died during hospitalization. An additional, critical factor in this respect was the age of the infected patients. Nonetheless, a positive correlation was demonstrated between the mortality rate and the number of positive SARS-CoV‑2 detections. Regarding the greater length of stay of patients tested positive for SARS-CoV‑2, the limited transfer options (further rehabilitation, skilled nursing facility) of the infected ones can be considered as causal. Particularly the vulnerable older patients are increasingly endangered by a combination of proximal femoral fracture and SARS-CoV‑2.

Abstract
OBJECTIVE To explore the mechanical stability of unstable pertrochanteric fractures with proximal femoral nail anti-rotation (PFNA-Ⅱ) fixation under different anteromedial cortical support reduction patterns. METHODS A 65-year-old healthy male volunteer with no history of hip or systemic disease was recruited. High-resolution computed tomography images with a slice thickness of 0.67 mm of his right femur were obtained. These images were used to establish three-dimensional (3D) models. The lesser trochanter and lateral femoral wall were cut off to create an AO Foundation/Orthopaedic Trauma Association type 31-A2 unstable pertrochanteric fracture model. PFNA-Ⅱ was used to simulate fixation. Nine different fracture reduction patterns, which included positive-positive, positive-neutral, positive-negative, neutral-positive, neutral-neutral, neutral-negative, negative-positive, negative-neutral, and negative-negative cortical support reductions, were simulated. A load of 700 N was applied to simulate a 70 kg elderly patient standing on one leg. The models were subjected to finite element analysis. The displacement and von Mises stress distributions were analyzed. RESULTS The positive-positive cortical support reduction pattern showed minimal stress and the negative-negative reduction pattern showed maximal stress on the intramedullary nail. The stress was mainly concentrated at the junction of the helical blade and the main nail and at the site of the lateral aspect of the insertion point of the nail in the great trochanter. The positive cortical support reduction patterns seemed to have smaller maximum displacements of the entire fragment-implant assembly and relative displacements between the head-neck and shaft fragments. Meanwhile, the negative reduction patterns seemed to have larger displacements. CONCLUSION The positive-positive support reduction pattern showed better mechanical stability for unstable pertrochanteric fractures. The negative-negative support reduction pattern was prone to fixation failure and should be avoided during an operation.

Abstract
Hintergrund und Fragestellung Proximale Femurfrakturen stellen mit ca. 100.000 Betroffenen/Jahr in Deutschland ein häufiges Krankheitsbild dar. Durch eine zeitnahe Versorgung (<24 h) konnte die Mortalität erheblich gesenkt werden. Ziele der Arbeit waren, die Prävalenz der Antikoagulation und hiermit assoziierte Komplikationen bei osteosynthetisch versorgter, proximaler Femurfraktur und deren Impact auf die präoperative Verweildauer zu analysieren und Potenziale zum optimalen perioperativen Gerinnungsmanagements aufzuzeigen. Material und Methoden Die Daten der externen vergleichenden Qualitätssicherung Nordrhein-Westfalen für die Jahre 2015 und 2016 wurden ausgewertet. Dabei wurden ausschließlich Fälle analysiert, bei denen eine hüftgelenknahe Femurfraktur osteosynthetisch versorgt wurde. Insgesamt wurden 24.786 Fälle hüftgelenknaher Femurfrakturen in die Studie eingeschlossen. Ergebnisse Von den Patienten mit einer antithrombotischen Dauertherapie (ATDT) wurden in der größten Subgruppe mit ASS-Medikation (n = 4005) 17 %, in der zweitgrößten Gruppe mit Vitamin-K-Antagonisten-Einnahme (n = 2157) 44,6 % und in der drittgrößten Gruppe mit Einnahme von direkten oralen Antikoagulanzien (DOAKs, n = 994) 18,2 % verzögert operiert. Schlussfolgerungen Das größte Potenzial zur Verkürzung der präoperativen Verweildauer ergibt sich in der Gruppe der Patienten, die ASS (17 % auffällig) oder einen Vitamin-K-Antagonisten (VKA, 44,6 % auffällig) einnehmen. Eine Antagonisierung der Wirkung von VKA lässt sich innerhalb kurzer Zeit durch die Gabe von Prothrombinkomplex (PPSB) erreichen. Auch unter der Einnahme von DOAKs muss das noch gängige Prozedere einer verzögerten operativen Versorgung kritisch hinterfragt werden. Die Etablierung eines Gerinnungsmanagements ist zu fordern. Neben der medizinischen Intervention (Gabe von Antidota) müssen Strukturen geschaffen werden, die eine zeitnahe Versorgung ermöglichen.
