Psoas Compartment Block Versus Periarticular Local Anesthetic for Total Hip Arthroplasty

Corewell Health East100 enrolled

Overview

The primary objective of this study is to examine whether there is a difference in the level of resting pain following total hip arthroplasty with an anterior approach with use of a psoas compartment block versus a local periarticular anesthetic infiltration

A single-center, prospective, randomized clinical trial with a total of 100 patients. One orthopaedic adult reconstruction surgeon at Beaumont Hospital Royal Oak (JJV) will perform all surgeries. After the patient has consented they will be randomized to one of the following two groups: 1. Psoas compartment block (n=50) 2. Periarticular local anesthetic infiltration (n=50), The patient will be blinded to the study group.
