case_images: Imaging revealed a transcervical fracture of the left proximal femur with lateral displacement of the distal femoral segment (Figure 1(a)). The final location of implants was confirmed on anterior-posterior and lateral X-ray imaging before irrigation and closure (Figure 1(b)).
case_images: (a) Visualization of the psoas muscle, femoral artery, and anterior inferior iliac spine (AIIS), iliopubic eminence (IPE), and the superior pubic (SP) ramus on sonoanatomy with identification. (b) Sonoanatomy.

case_images: The probe was then rotated counterclockwise, aligned with the pubic ramus to visualize the AIIS, iliopubic eminence (IPE), femoral artery, psoas muscle, and the superior pubic ramus (Figure 2).
case_images: Echogenic needle isolation following contact with the iliopubic eminence. FA: femoral artery; FN: femoral nerve. Arrow represents the needle placement.

case_images: Under direct visualization, a 22-gauge (G), 80 mm echogenic needle was advanced in-plane, lateral to medial between the psoas tendon and pubic ramus until the needle made contact with the IPE (Figure 3).
case_images: (a) PENG catheterization and corresponding sonoanatomy with isolation of the proximal portion of the peripheral nerve catheter positioned above the iliopubic eminence. Arrow presents the catheter; (b) PENG catheter placement.
