Regional anesthesia is increasingly being performed in patients with hip fracture, offering better analgesia and lower consumption of opioids reducing their side effects. Recently, the sensitive innervation of the hip joint and the mechanism of action of different nerve blocks have been studied. This has led us to develop a novel ultrasound-guided approach for blockade of articular branches of the hip nerves, pericapsular nerve group. Which blocks only the sensory articular branches unilaterally. Technique: with the patient in the dorsal position, the transverse convex transducer is placed on the anterior inferior iliac spine, then align with the Iliopectineal eminence of the pubic branch rotating it 45º counter clockwise. An 80 mm flat needle is inserted lateral to medial and the local anesthetic is deposited deep in the psoas tendon. Discussion: The identification of sonoanatomy is fundamental in the PENG block, it is not an advanced block, but the anesthesiologist could have an unsuccessful block and lose all the benefits of this technique. Therefore, we present the images in detail of the procedure.
