Inflammatory Indices, Early Mortality, and ICU Stay in Geriatric PFN Patients

This retrospective observational cohort study aims to evaluate the association between preoperative and postoperative inflammatory indices and early postoperative outcomes in geriatric patients undergoing proximal femoral nailing (PFN) for intertrochanteric femur fractures. The primary outcome of the study is 30-day mortality, while the secondary outcome is intensive care unit (ICU) length of stay. Various inflammatory biomarkers derived from routine laboratory parameters, including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), systemic immune-inflammation index (SII), systemic inflammation response index (SIRI), immune-inflammatory prognostic index (IPI), aggregate index of systemic inflammation (AIS), and RDW-to-albumin ratio (RAR), will be analyzed to investigate their prognostic value in the acute postoperative period. The study seeks to identify simple and readily accessible biomarkers that may contribute to early risk stratification and perioperative management in elderly hip fracture patients.
