The Gel Box – a Testing Device for the Characterization of Cryo- and Radiofrequency Lesions Employed in Interventional Pain Therapy

摘要

Radiofrequency (RF) and cryolesioning are established methods for the therapeutic interruption of sensory nerve supply to facet joints and other painful musculoskeletal structures. The varying clinical success rates of these treatments have – among other technical issues – been attributed to the small size of these lesions combined with the limited precision in placing them. Since there are 2 different physical methods for lesioning and a wide range of probes and lesion generators available, it is likely that the lesions generated by them may be of different size.
