Lumbar Erector Spinae Plane Block for Total Hip Arthroplasty Comparing 24-Hour Opioid Requirements: A Randomized Controlled Study

<div>Ultrasound image of lumbar erector spinae plane block. LD = latissimus dorsi; ESM = erector spinae muscle; LA = local anesthetic; <i>L</i>1 = lumbar transverse process; <i>L</i>2 = lumbar transverse process; PM = psoas muscle. The white arrow indicates needle placement using an out-of-plane technique. The local anesthesia is injected just below the erector spinae muscle and above the transverse process of the targeted vertebral body.</div>
