Erector spinae plane block for bilateral lumbar transverse process fracture in emergency department: A new indication.

Plane blocks have become very popular in recent years with the introduction of ultrasonography into the regional anesthesia and algology practice. Ultrasound guided erector spinae plane (ESP) block was first described in 2016. ESP block involves injection of local anesthetics between erector spinae muscles and transverse process of thoracic or lumbar vertebrae and can block the dorsal and ventral rami of thoracolumbar spinal nerves. ESP block has been successfully reported to relieve the pain of multiple rib fracture in the emergency department (ED). Here we first report a novel indication for ESP block in ED; transverse process fracture of lumbar vertebra.
