Fractures in and around the hip are quite common irrespective of both the young and elderly population groups and are associated with extreme pain. A hip fracture is a serious injury, with complications that can be life-threatening and is a common orthopedic emergency in the elderly. Early surgery within 48 h of fracture has shown to decrease the complication and mortality rates.~Spinal anaesthesia is the most common mode of anaesthesia used to fix these fractures. Extreme pain due to fracture does not allow ideal positioning for these procedures. and hence a problem to access the subarachnoid space. Inadequate postoperative analgesia can restrict the limb mobility thereby delaying recovery along with increased consumption of opioids.~Effective perioperative analgesia that reduces the requirement of opioids and its adverse effects is essential in this population.~The anterior hip capsule is innervated by articular branches of femoral nerve, obturator nerve and accessory obturator nerve (AON) as reported by previous anatomic studies, suggesting that these nerves should be the main targets for hip analgesia, which can be blocked by Peri-capsular nerve group (PENG) .~PNB with lower volume and higher concentration of local anesthetic was more efficacious than higher volumes and lower concentrations of local anesthetic of equivalent dose.~Using this information, we will conduct this study to evaluate the efficacy of bupivacaine at three different concentration and doses in equivalent volume used in ultrasound guided PENG block for positioning & post-operative analgesia.
