Hip fracture is a common orthopedic emergency in the elderly, and it is associated with significant morbidity and mortality.1 Surgical reduction and fixation are the definitive treatment in most patients.2 Effective perioperative analgesia that minimizes the need for opioids and related adverse effects (such as delirium) is essential in this patient population.~Regional analgesic techniques, including femoral nerve (FN) block, fascia iliaca block (FIB), and 3-in-1 FN block, are popular analgesic strategies, due mainly to their opioid-sparing effects and reduction in opioid-related adverse effects. The effect size of analgesia from these blocks is only moderate, and literature suggests that the obturator nerve (ON) is not covered.~The anterior hip capsule is innervated by the ON, accessory obturator nerve (AON), and FN as reported by previous anatomic studies. The anterior capsule is the most richly innervated section of the joint, suggesting these nerves should be the main targets for hip analgesia. A recent anatomical study by Short et al15 confirmed the innervation of the anterior hip by these 3 main nerves but also found that the AON and FN play a greater role in the anterior hip innervation than previously reported. This study also identified the relevant landmarks for those articular branches. The high articular branches from FN and AON are consistently found between the anterior inferior iliac spines (AIIS) and the iliopubic eminence (IPE), whereas the ON , close to the inferomedial acetabulum. Using this information, the investigator developed an ultrasound-guided technique for blockade of these articular branches to the hip, the PENG (PEricapsular Nerve Group) block. In this study, the investigator will examine the efficacy of PENG block in hip surgeries as a post-operative pain management technique in comparison with fascia Iliaca block in hip surgeries
