Ultrasound guided Erector Spinae Plane block at L-4 transverse process level provides effective postoperative analgesia for total hip arthroplasty

First described by Forero in 2016 for the treatment of thoracic neuropathic pain, Erector Spinae Plane (ESP) block is a regional anesthesia technique in which local anesthetic is injected between the erector spinae muscle and transverse process under ultrasound guidance, blocking the dorsal and ventral rami of the thoracic and abdominal spinal nerves [1,2]. Studies have shown that the spread of local anesthetic in the paravertebral space in the cephalic and caudal direction can lead to analgesia from C7-T2 to L2-3 [2].
