Suprainguinal Fascia Iliaca Block Versus PENG Block for Hip Arthroplasty Analgesia

September 26, 2021 updated by: Julian Aliste, University of Chile

A Randomized Comparison Between Ultrasound-Guided Suprainguinal Fascia Iliaca Block and Pericapsular Nerve Group Block For Total Hip Replacement

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.

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.
Experimental: Pericapsular nerve group block
Twenty mL of levobupivacaine 0.5% with epinephrine 5 ug/mL will be deposited in the anterior aspect of the iliac bone between its periosteum and the tendon of the iliopsoas muscle.
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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Presence of quadriceps motor block (defined as paralysis or paresis).
Time Frame: 6 hours after block performance
Quadriceps motor function will be tested with the patient supine and with the hip and knee flexed at 45º and 90º, respectively. The subject will be asked to extend the knee first against gravity and then against resistance. Quadriceps strength will be graded according to a 3-point scale: normal strength = 0 point (extension against resistance); paresis = 1 point (extension against gravity but not against resistance); and paralysis = 2 points (no extension).
6 hours after block performance

Secondary Outcome Measures
