Bilateral lumbar nerve radiofrequency thermocoagulation as a nerve root block for leg spasticity due to thoracic spinal cord injury: a case report

Abstract

Herein, we report a case in which radiofrequency thermocoagulation (RFTC) as a nerve root block was extremely effective for leg spasticity caused by thoracic spinal cord injury. The patient was a 13-year-old girl who developed involuntary movement of her lower limbs, accompanied by intractable pain around her knees. She previously underwent bilateral Achilles tendon and hamstring tendon surgeries several times to treat these symptoms, but without any resolution; moreover, her activity of daily living (ADL) progressively deteriorated. After providing sufficient explanations about the risks and benefits of RFTC, and obtaining consent from both the patient and her family, we performed bilateral RFTC (90℃ for 180 seconds each) of the lumbar 2–4 nerve roots under general anesthesia. Fortunately, the technique was extremely effective, and her involuntary movement and pain disappeared completely. Presently, the patient's ADL has remarkably improved, and she can go to school.
