Artificial Intelligence-Assisted vs Surgeon-Planned Trajectories in Freehand Femoral Neck Screw Fixation

Femoral neck fractures, occurring between the femoral head and the base of the femoral neck, are among the most common hip injuries, particularly in the elderly population. While surgical fixation with closed reduction and cannulated screws is a widely accepted standard, challenges such as suboptimal screw placement, prolonged fluoroscopy exposure, and increased risk of complications like nonunion or avascular necrosis persist-largely influenced by surgeon experience and intraoperative variability. To address these limitations,this trial investigates the effectiveness and safety of artificial intelligence (AI)-assisted versus surgeon-directed screw path planning in freehand percutaneous internal fixation of femoral neck fractures.
