Ultrasound-Guided PENG Block vs Femoral Nerve Block for Analgesia Before Spinal Anesthesia in Hip Fracture Surgery

This study will compare two types of ultrasound-guided nerve blocks-Pericapsular Nerve Group (PENG) block and Femoral Nerve Block (FNB)-to evaluate their effectiveness in reducing pain before spinal anesthesia in patients who will undergo surgery for proximal femur fractures. Proximal femur fractures will continue to be common, especially in older adults, and often will cause severe pain that will make it difficult to position patients for spinal anesthesia. Both nerve blocks will aim to reduce pain, improve comfort during spinal anesthesia, and decrease the need for postoperative pain medication. A total of 60 adult patients who will undergo proximal femur fracture fixation under spinal anesthesia will be enrolled and randomly assigned to receive either a Pericapsular Nerve Group (PENG) block or a femoral nerve block before the procedure. The study will monitor patients' pain scores using the Visual Analog Scale (VAS) at multiple time points, including during positioning and throughout the first 24 hours after surgery. It also will evaluate how long it will take before the patients require rescue pain medication, and how much total pain medication will be needed.
