Background: Femur fracture causes moderate to severe pain which requires effective analgesia both preoperatively and postoperatively. Multimodal analgesic regimens which includes non-steroidal anti-inflammatory drugs, opioids and regional analgesic techniques have been used in femur fracture patients so far. Peripheral blocks was initially done with either paresthesia technique or nerve stimulation-based technique. Ultrasound guided needle &catheter placement is observed to be technically superior, more accurate, being placed in peripheral location probably increases the safety of USG guided compared with other techniques.
