Summary

In recent years, suprainguinal fascia iliaca block (SFIB) has emerged as a reliable analgesic option for primary total hip arthroplasty (THA). In 2018, a new block was described, termed pericapsular nerve group block or PENG block, that selectively targets the articular branches of the femoral and obturator nerves while sparing their motor components. In this randomized trial, the investigators will compare US-guided SFIB and PENG block in patients undergoing primary THA. Since the main benefit of PENGB stems from its quadriceps-sparing effect, it was selected the incidence of quadriceps motor block (at 6 hours) as the primary outcome and the hypothesis that PENG block will result in significantly less motor block compared to SFIB.

Interventions

Type	Name	Description
PROCEDURE	Ultrasound-guided suprainguinal fascia iliaca nerve block	After an ultrasound-guided insertion of a block needle below the inguinal ligament, the needle will be advance in the plane between fascia iliaca and iliopsoas muscle up to a point cranial to the ligament in order to inject a 40 mL of adrenalized 0.25% levobupivacaine.
PROCEDURE	Ultrasound-guided pericapsular nerves group of the hip block	After an ultrasound-guided insertion of a block needle at the level of the inguinal ligament, the needle will be advance into the plane between iliac bone periosteum and the tendon of the iliopsoas muscle in order to inject 20 mL of adrenalized 0.5% levobupivacaine.
