Laura Girón-Arango et al. Reg Anesth Pain Med. .

Abstract

This educational article discusses the current understanding of the pericaspular nerve group block (PENG) of the hip regarding its mechanism of action and spread patterns, as well as plausible explanations for postblock quadriceps weakness. Finally, we will discuss the recent evidence of PENG block as an analgesic block in hip fractures and in different hip surgeries.
