Ultrasound-Guided Percutaneous Radiofrequency Thermal Neuroablation for the Treatment of Adductor and Rectus Femoris...

Spasticity is a very frequent complication of spinal cord injury (SCI) that can limit activities of daily living, reduce the quality of life, and augment caregiver burden. This problem has many treatment options that should be selected according to the clinical and functional scenario.  This case study presents a 60-year-old female patient with complete spastic paraplegia after a spinal stroke. Spasticity interfered with activities of daily living, mainly with intermittent catheterization and transfers, and botulinum toxin injections failed to efficiently treat this issue. It was decided to perform an ultrasound-guided radiofrequency thermal ablation of the anterior and posterior branches of the obturator nerve and motor branches to the rectus femoris of the femoral nerve to treat the adductors and rectus femoris spasticity. One year after the radiofrequency treatment, the patient showed considerably reduced spasticity, allowing her caregiver to do transfers and easier intermittent urinary catheterizations. Nerve radiofrequency thermal ablation has the potential to be an effective therapy in lower limb spasticity, with long-lasting effects.
