HipSTHeR - Registerbased Randomized Controlled Trial Comparing Hip Screws or (Total) Hip Replacement for Undisplaced Femoral Neck Fractures in Elderly Patients

What this Trial Is About

This research aims to determine if hip replacement surgery (arthroplasty) can reduce the need for additional operations compared to internal fixation in elderly patients with an undisplaced femoral neck fracture. Patients aged 75 years and older with this type of fracture will be included and randomly assigned to one of two treatments through the Swedish Fracture Register platform. The study focuses on combining reoperation rates and mortality into a single main outcome measure to evaluate which treatment offers better results. Participants will receive either arthroplasty, which may be hemi or total hip replacement depending on the patient's condition and surgeon's decision, or internal fixation using screws, pins, or a sliding hip screw device based on hospital routine. The study is a randomized controlled trial without blinding, comparing these two device-based treatments for hip fractures in elderly patients. During the study, researchers will monitor the combined rate of reoperations and mortality for 1 to 2 years after surgery. Additional outcomes include reoperation rates, short- and long-term mortality, and patient-reported physical function one year after surgery. Participants will be followed up to assess these outcomes, with care taken to track their progress and safety over the study period.
