Summary

In a recent study, direct periarticular local anesthetic infiltration (PAI) showed a greater incidence of early quadriceps weakness (33% at 3 hours and 13% at 6 hours) than pericapsular nerve group block (PENGB) in total hip arthroplasty (THA) but, in turn, demonstrated a statistically significant better pain control. Additionally, PENGB could not completely circumvent motor compromise either, particularly at 3 hours (20% incidence), probably secondary to an injectate migration towards the femoral nerve. Posteriorly to this publication, a cadaveric trial looking into the maximum effective volume that spared the femoral nerve resulted in 13.2 mL.

This newer evidence led to the design of a strategy that combines both interventions, aiming to obtain the best of them and have a solid alternative for those cases where very early mobilization is pursued.

Thus, it is hypothesized that posterior PAI added to a low-volume PENGB (10mL) represents a superior alternative to PAI in terms of strength preservation and provides effective analgesia during the first 24 postoperative hours after THA.

Interventions

PROCEDURE

Periarticular Local Anesthetic Infiltration

Sixty milliliters of 0.25% bupivacaine + 5ug/mL epinephrine and ketorolac 30 mg will be deposited by the orthopedic surgeon at the periarticular level under direct vision during surgery. Fascia, subcutaneous tissues, and skin will also be infiltrated with part of the solution before wound closure.

PROCEDURE

Posterior Periarticular Local Anesthetic Infiltration plus Pericapsular Nerve Group Block

From a total of forty-five milliliters of 0.25% bupivacaine + 5ug/mL epinephrine and ketorolac 30 mg, 15mL will be deposited by the orthopedic surgeon at the posterior periarticular level under direct vision during surgery. Fascia, subcutaneous tissues, and skin will also be infiltrated with part of the solution before wound closure with the remaining 30mL. After wound closure, an ultrasound-guided pericapsular nerve group block will be performed by an anesthesiologist by injecting 10mL of 0.5% bupivacaine + 5ug/mL epinephrine in the plane between the iliac bone periosteum and the tendon of the iliopsoas muscle.
