Surgeon-Performed Intraoperative Pericapsular Nerve Group Block in Total Hip Replacement: A Cadaveric Feasibility Study

This cadaveric study demonstrates that intraoperative surgeon-performed PENG block placement through a posterior approach is anatomically feasible and accurately replicates the needle position of the conventional ultrasound-guided technique. These findings support the anatomical validity of this approach; however, further in vivo studies are required to evaluate its clinical efficacy and safety.
