Farhang M, et al. - In a cohort study, the plain radiographs of all individuals with proximal femur fractures (PFF) aged over 50 years who were admitted to Umeå University Hospital in 1981/82, 2002 and 2012 were involved by the researchers in order to discover whether the radiological severity of PFF fractures had progressed over time. The ratio of undisplaced to displaced femoral neck (FN) fractures in 1981/82, 2002 and 2012 was 30 to 70%, 28 to 72%, and 25 to 75%, respectively. The ratio of stable to unstable intertrochanteric (IT) fractures was 64 to 36%, 68 to 32%, and 75 to 25% in 1981/82, 2002 and 2012, respectively. The ratio of simple to comminute subtrochanteric fractures in 1981/82, 2002 and 2012 was 35 to 65%, 16 to 84%, and 12 to 88%. No statistical variations among these 3 study periods in both FN and IT fractures were noted. In subtrochanteric fractures, a tendency towards more comminute subtrochanteric fractures was observed. Hence, in the radiological severity of FN and IT, no important increment over a 30 years’ period was concluded. Nevertheless, there was a tendency towards a rise in comminute subtrochanteric fractures.
