Pericapsular Nerve Group Block for Elective Hip Arthroplasty

Optimized analgesia is crucial for early mobilization after hip arthroplasty. Regional anesthesia, like fascia iliaca block or femoral nerve block, have limited indication because of motor blockade whereas local infiltrations analgesia have shown conflicting analgesic efficacy results in hip arthroplasty. Pericapsular nerve group (PENG) block is a new regional anesthesia technique targeting specifically sensory nerve branches of the hip articulation. It has been originally described in hip fracture patients. The aim of this study is to evaluate the efficacy of PENG block on analgesia after elective hip arthroplasty.
