Fractures of the femur are common orthopaedic emergency especially in the geriatric population and central neuraxial blocks are the preferred technique for providing anaesthesia. However, limb immobility and extreme pain are the deterrents for ideal positioning for these procedures. postoperative pain is a nightmare so adequate analgesia has been advocated to reduce the pain. in this study, Facia Iliaca compartment block will be compared to anterior Quadratus lumborum block, both will be done Ultrasound-guided using Bupivacain0.25% for postoperative analgesia at the end of the surgery.

In this prospective, randomized, comparative study patients will be equally divided into two equal groups; GroupI: patients will receive Ultrasound-guided Facia Iliaca compartment block with 50 ml 0.25%bupivacaine at the end of surgery Group Q: patients will receive Ultrasound-guided anterior Quadratus lumborum block with 50 ml 0.25%bupivacaine at the end of surgery
