Summary

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.

  • Proximal Femur Fracture
  • Hip Fracture
  • Pain Management
  • Spinal Anesthesia

Interventions

PROCEDURE

Pericapsular Nerve Group (PENG) Block

Assigned Interventions: Procedure/Surgery: Pericapsular Nerve Group (PENG) Block An ultrasound-guided nerve block targeting articular branches of the femoral, obturator, and accessory obturator nerves. Performed under aseptic technique using a curved low-frequency ultrasound probe to visualize the iliopsoas plane and pubic ramus. Drug: Bupivacaine (0.25%, 30 ml) Local anesthetic used to provide analgesia in nerve block. Drug: Magnesium sulfate (10%, 5 ml = 500 mg) Adjunct used to enhance analgesic efficacy of the block.

PROCEDURE

Femoral Nerve Block (FNB)

An ultrasound-guided nerve block targeting the femoral nerve to provide analgesia before spinal anesthesia in proximal femur fracture surgery. Administered using 30 ml of 0.25% bupivacaine and 5 ml of 10% magnesium sulfate (500 mg). The block is performed with an in-plane ultrasound approach, identifying the femoral nerve lateral to the femoral artery under sterile conditions.
