Increased all-cause mortality following proximal humerus fractures in Danish adults: a register-based matched cohort study of 93,952 fracture cases and 469,760 controls.

Although these methodological differences limit direct comparisons, our findings align with the overall trend observed across Nordic studies, demonstrating a notably higher mortality among PHF patients compared to the general population[ 9 – 12 ], particularly within the first 30 and 90 days after the fracture, with a decreasing trend onwards[ 8 , 10 , 11 ].
