In patients with continued pain despite these measures, nerve ablation may provide significant relief. Rhizotomy is commonly performed by radiofre-quency ablation (RFA); cryo-denervation has been reported in Europe 2 17 1. Ablation of the dorsal nerve roots supplying the painful facet joint provides sig-nificant relief, but due the innate ability of peripheral nerves to regenerate, improvement is impermanent. Theoretically, removal of the capsular tissue within the joint, which contains the peripheral nerve endplate receptors, should prevent nerve regeneration. Without endplate receptors present within the joint, dorsal root axons should be incapable of reinnervating the joint.
