Pericapsular nerve group block and lateral femoral cutaneous nerve block versus fascia iliaca block for multimodal analgesia after total hip replacement surgery: A retrospective analysis.

Background: Optimal pain control with limited muscle weakness is paramount for a swift initiation of physical therapy and early discharge. Fascia iliaca compartment block (FICB) has been recommended since it offers good pain control with a low risk of motor block. Pericapsular nerve group (PENG) block with lateral femoral cutaneous block (LFCN) has been proposed as an effective alternative to FICB that offers better pain control with a considerably lower risk of motor block.
