Cooled Radiofrequency Ablation for the Treatment of Refractory Phantom and Residual Limb Pain; a Pilot Study.
In Brief
A clinical study evaluating Cooled Radiofrequency Ablation for Phantom Limb Pain and Neuroma Amputation. Completed, enrolled 8 participants across 1 site.
Detailed Summary
To assess changes in pain, physical function, and health-related quality of life in patients with post-amputation neuroma-associated residual limb pain after cooled radiofrequency ablation.
Study Details
Timeline
Interventions
RFA procedures will be performed with modification accounting for appropriate C-RFA technique. Participant will be positioned prone and skin prepped with chloroprep. Ultrasound probe will be placed on residual limb at a transverse angle in order to view the nerve and associated neuroma in long-axis. The probe will be advanced to the site of the stump neuroma. C-RFA electrode will be placed adjacent to neuroma. Needle will be connected via wire to a cooled radiofrequency generator. Motor and sensory testing will be performed to reproduce or exacerbate the RLP and / or PLP. At the site of the neuroma, 2 mL of local anesthetic will be injected through the needle. C-RFA lesions will be created by using the typical C-RFA protocol. Upon completion needle will be removed. Following ablation, 0.5 mL of 0.5% bupivacaine will be injected at the site of the ablated neuroma to provide post procedure analgesia.
