A comparative study between postoperative analgesia of suprainguinal fascia iliaca compartment block (SIFI) and lumbar erector spinae plane block (ESPB) in hip arthroplasty

Background Suprainguinal fascia iliaca (SIFI) block offers efficient pain relief in total hip arthroplasty, although motor blockage is a common complication. Erector spinae plane block (ESPB) is a promising technique with less motor block; in research, we evaluate the efficacy of both blocks regarding analgesia and early mobilization.
