title: The 13-year observation of hip fracture in Poland-worrying trend and prognosis for the future.
abstract: BACKGROUND
  Hip fractures are often considered to be one of the most common osteoporotic fractures. In our previous study, we noted the increasing trend in the total number of hip fractures as well as crude and standardized rates, for both women and men. This observation enabled us to delve deeper into the study of osteoporotic fractures.
  
  
  METHODS
  Hospital records between 1.01.2002 and 31.12.2014 with ICD-10 codes S72.0. S72.1 and S72.2 (femoral neck. intertrochanteric, subtrochanteric, and inter and subtrochanteric fracture) were analysed. All fractures occurred in citizens who lived in the district Tarnowskie Góry and the city of Piekary Śląskie aged 50 years and more.
  
  
  RESULTS
  1507 fragility hip fractures (400 in men, and 1107 in women) were registered. The rates increase in both sexes was still observed. The tendency to sustain fractures was lower in female (29.3%) than in the male population (63.6%). We observed a lower increase in urban (35.8%) population when compared to rural (40.8%) population. Incidence rate ratios for female gender were 1.89 (95% CI 1.65-2.18). The rates in 2014 were as follows: crude rate of 216.2 (men 140.9; women 276.5) and standardized 183.9 (131.6 and 219.4, respectively). This observation allowed as to project a total crude rate of 467.2 (men 329.6; women 584.7) for the year 2050.
  
  
  CONCLUSIONS
  The number of osteoporotic hip fractures in Polish men and women is still relatively low, but the epidemiological situation is getting worse. The over 13 years of follow-up demonstrated that the trend to increase in total number of hip fractures for men and women is still observed. This prognosis is of a major concern.
