Ultrasound guided erector spinae plane block (ESPB) has been widely used at thoracic level. There has been a recent interest in utilising ESPB at lumbar level. Available literature is in the form of case reports. In this series involving 10 cases with proximal femur fractures, we have described unilateral ultrasound guided lumbar ESPB at L3 level for managing postoperative analgesia with continuous local anaesthetic infusion for 48 hours. The visual analogue scale score was always below 4, and there were no adverse effect or complications due to the block.
