Abstract
INTRODUCTION: The aim of this study was to present recent epidemiological data on extremity and axial skeletal fractures in German hospitals and to compare them with older data to detect time trends. MATERIALS AND METHODS: Inpatient data from the German National Hospital Discharge Registry were used. The absolute number and age-standardized incidence of fractures in 2002 and 2018 were analysed by fracture location according to the International Classification of Disease. Data were analysed according to age group. Male: female ratios (MFRs) and incidence rate ratios (IRRs) were calculated to compare the 2018 and 2002 data. RESULTS: The absolute number of fractures of the nine analysed locations was 15.2% higher in 2018 than in 2002. By fracture location, the changes were as follows (absolute change + IRR): "neck" (S12): + 172%, IRR = 2.6; "rib(s), sternum, thoracic spine" (S22): + 57%, IRR = 1.3; "lumbar spine and pelvis" (S32): + 66%, IRR = 1.3; "shoulder and upper arm" (S42): + 36%, IRR = 1.2; "forearm" (S52): + 13%, IRR = 1.0; "wrist and hand level" (S62): - 32%, IRR = 0.7; "femur" (S72): + 24%, IRR = 0.9; "lower leg, including ankle" (S82): - 24%, IRR = 0.7; "foot, except ankle" (S92): - 4%, IRR = 0.9. The overall MFR changed from 0.7 in 2002 to 0.6 in 2018. The age group of 45-54 years represented a turning point, males were more often affected than females in the younger age groups, and the opposite trend was observed in the older age groups. CONCLUSIONS: The increase in the absolute fracture rates was due to increased rates of femur, shoulder, upper arm, forearm, and axial skeletal fractures, with elderly women being the main contributors. Femur fractures were found to be the most common fractures treated in German hospitals.
