Ultrasound-Guided Lumbar Paravertebral Block After Pre-Designed Route on X-Ray Film for Radicular Pain Following Failed Back Surgery Syndrome: A Case Report

摘要

Persistent or recurring radicular pain after lumbar surgery is a clinical condition of failed back surgery syndrome (FBSS) that seriously affects the life quality of patients. Conventional medication and physiotherapy do not fully relieve this pain. A simpler, safer, and less invasive option is lumbar selective nerve root block or paravertebral block. Here, we share our experience regarding lumbar paravertebral block for a patient with FBSS, which successfully alleviated radicular pain after lumbar surgery.
