Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Repeat Percutaneous radiofrequency facet joint denervation (neurotomy) - This involves lesioning via use of percutaneous electrodes of selected pain-producing lumbar medial branches percutaneously using radiofrequency with pulsed time cycle of 2×2 msec/second and maximum probe tip temperature of 90 degrees celsius. In this trial a single group will recieve a procedure and then a 12 month followup
Intervention code [1] 2593 0
Treatment: Other
Comparator / control treatment
Same group (i.e. subjects acting as their own control via their preoperative LBOS) but using baseline low back outcome scores before repeat radiofrequency facet joint denervation. The technique used for previous RFJD procedures done on this group used an identical radiofrequency technique and radiofrequency settings that will be done prospectively upon the same group (i.e. the same procedure is being repeated in the same group.
