Effectiveness of pulsed radiofrequency on the medial cervical branches for cervical facet joint pain

Figure 1 Under fluoroscopic guidance, the catheters were inserted for pulsed radiofrequency stimulation of the Lt. C5, 6, and 7 medial branches. The catheter tips were placed around the Lt. C5, 6, and 7 cervical medial branches. A: Posterior-anterior view; B: Lateral view.

Figure 2 Changes in numeric rating scale score for cervical facet joint pain over the assessment period. The numeric rating scale scores significantly reduced from 5.3 prior to treatment to 2.4 at 1 mo, and 3.1 at 3 mo after pulsed radiofrequency treatment. ^aP < 0.05 indicate a significant result. NRS: Numeric rating scale.
