Bögl HP, Michaelsson K, Zdolsek G, et al. - Researchers assumed that individuals with surgically treated, complete atypical fractures have a higher risk of any reoperation and reoperation related to healing complications than individuals with common femoral shaft fractures but that this increase would become insignificant when adjusted for predefined characteristics. Researchers included a cohort of 163 individuals with atypical fractures and 862 individuals with common femoral shaft or subtrochanteric fractures treated between 2008 and 2010 and who had follow-up radiographs and register data available until 31 December 2014. They distinguished reoperations by a complementary review of radiographs and register data and were applied to estimate risks for any reoperation and reoperations related to healing complications. The data imply that after an atypical femur fracture, the elevated risk of reoperation is largely explained by individual characteristics and not fracture type.
