This randomized study aims to compare the efficacy and hemodynamic effects of hypobaric unilateral spinal anesthesia (HUSA) and lumbar plexus block (LP-SP) in patients undergoing femoral neck fracture surgery. Conducted at a single center, the study includes 60 patients aged 18 to 90, classified as ASA I-IV, and evaluates anesthesia methods' impact on intraoperative parameters, including blood pressure, sedation needs, and recovery outcomes. The findings will inform anesthetic strategy selection based on patient characteristics and surgical requirements.
