Objective. Increasing use of magnetic resonance imaging (MRI) in acute knee trauma has led to increased awareness of bone bruises (BB). Post-traumatic BB is the only predictor of early osteoarthritis. The aim of our research is to determine the way in which it is possible to observe and precisely determine the localization, size, and number of BBs, by the correct selection of MR imaging sequences. Methods. MR examinations of the knees performed during 2012-2013 in 100 subjects with an acute knee injury sustained during sports were retrospectively analyzed from the personal archive. All examinations were done in the first month after the trauma. Examinations were performed on an open-type MRI with a power of 0.3T. A standard protocol was used with sequences of spin echo T1-weighted in the sagittal plane, fat suppression T2-weighted in the sagittal, coronal, and axial planes, and Short Tau Inversion Recovery (STIR) in the coronal plane. The presence and arrangement of BB were analyzed. The difference in the frequency of BB findings in STIR compared to the T1W sequence and the assessment of the visibility of BB in both sequences were analyzed. Results. BB findings were observed in 51% of subjects. BB is, after effusion, the second, most frequent pathological finding on MR examination in acute knee trauma. A significant statistical difference was determined by the Wilcoxon test (Z=-5.067, p=0.000) between the T1W and STIR sequence, which indicates that the STIR sequence is convincingly more sensitive than the T1W sequence for the diagnosis of BB. Conclusion. It was concluded that STIR sequence provides better visibility of BB compared to T1W sequence. © 2023, Serbian Medical Society. All rights reserved.

Background and Objectives: The epidemiological pattern of the hip fracture burden attributable to falls in Central European countries is still insufficiently known. The aim of this study was to assess the regional and national trends of hip fractures due to falls in Central Europe from 1990 to 2019. Materials and Methods: Using the Global Burden of Disease (GBD) 2019 study, this descriptive epidemiological study presents trends in incidence of and Years Lived with Disability (YLDs) from hip fractures due to falls in the region of Central Europe. All estimates (age- and sex-specific rates, and age-standardized rates) were expressed per 100,000. A joinpoint regression analysis was used to assess trends: the average annual percent change (AAPC) with a corresponding 95% confidence interval (95% CI) was calculated. Results: Among all new cases of hip fracture in the population as a whole in Central Europe in 2019, 3.9% in males and 7.0% in females were attributable to falls, while the share of hip fractures due to falls in the population aged 70 and over was 16.9% in males and 20.0% in females. About 400,000 new cases of hip fracture due to falls occurred in the Central European region in 2019 (220,000 among males and 160,000 among females), resulting in 55,000 YLDs (32,000 in females and 22,000 in males). About one-third of all new cases (59,326 in males and 72,790 in females) and YLDs (8585 in males, and 10,622 in females) of hip fractures due to falls were recorded in Poland. From 1990 to 2019, the age-standardized incidence rates of hip fracture due to falls showed a decreasing tendency in females (AAPC = −1.1%), and an increasing tendency in males (AAPC = 0.1%). Both in males and females, YLDs rates of hip fracture due to falls in the Central European region decreased (AAPC = −1.6% and AAPC = −2.4%, respectively). Conclusions: Hip fracture due to falls represents an important health issue in the Central European region, although incidences and YLDs declined in the most recent decades. However, further efforts to reduce the burden of hip fractures attributed to falls are needed. © 2023 by the authors.
