Today's hip edition covers six critical topics in geriatric hip surgery and perioperative optimization. We examine long-term functional outcomes comparing hemiarthroplasty to total hip arthroplasty in octogenarians, explore promising interventions to prevent postoperative delirium, analyze the survival impact of sustained nutritional supplementation, evaluate optimal tranexamic acid strategies for blood conservation, investigate novel biomarkers for mortality prediction, and assess the clinical implications of preoperative anemia. All studies provide practical insights for improving outcomes in this vulnerable patient population.
