Additionally, PENGB could not completely circumvent motor compromise either, particularly at 3 hours (20% incidence), probably secondary to an injectate migration towards the femoral nerve. Posteriorly to this publication, a cadaveric trial looking into the maximum effective volume that spared the femoral nerve resulted in 13.2 mL.\n\nThis newer evidence led to the design of a strategy that combines both interventions, aiming to obtain the best of them and have a solid alternative for those cases where very early mobilization is pursued.\n\nThus, it is hypothesized that posterior PAI added to a low-volume PENGB (10mL) represents a superior alternative to PAI in terms of strength preservation and provides effective analgesia during the first 24 postoperative hours after THA.",[78,79],"Hip Osteoarthritis","Postoperative Pain",[81,82,83,84],"Nerve block","Periarticular infiltration","Hip replacement","Early rehabilitation","2025-01-15",{"date":87,"type":88},"2025-01-17","ACTUAL",{"date":90,"type":88},"2023-10-18",{"date":92,"type":72},"2025-10-23",{"name":5,"class":6},1]
