Arthroplasty versus internal fixation for displaced femoral neck fractures in older patients with dementia: a target trial emulation study

Background and purpose: Target trial emulation can improve design transparency in observational comparative-effectiveness studies. We applied the framework to compare the outcome after arthroplasty with that of internal fixation (IF) in patients with dementia and displaced femoral neck fracture regarding recorded reoperation, mortality, length of stay, and postoperative mobility.
