  1. Values are presented as number of patients (% of patient group) or median [25th – 75th percentiles]. P-values represent differences between men and women in number of patients affected or median values by the use of aMann-Whitney U test for continuous variables and bPearson’s Chi-square test or cFisher’s exact test (in small sample groups) for categorical variables. Every injured structure is counted for each patient, i.e. several structures are scored for some patients and consequently sum of column percentage in the category Injured structure is not 100%. *The number of forearm fractures is not representative for the entire population
