Abstract |
Objective Cervical radiating pain affects approximately one on 1,000 adults per year. Although many treatment modalities are
described in the literature, the available evidence for efficacy is not sufficient to allow definitive conclusions on the optimal therapy to be made. The goal of this study was to establish the benefits and prognostic factors of pulsed radiofrequency (PRF) on
the cervical dorsal root ganglion (DRG) for cervical radiating pain.
Methods A retrospective study of the results of PRF treatment of the cervical DRG in 22 patients with cervical radiating pain
was carried out. Diagnostic block of cervical DRG were performed before PRF. PRF was applied for two minutes at a setting of
2×20ms/s and 45V by two times on the same targets. Visual analogue scale (VAS) was evaluated at the two week, one, three,
six months and compared with pretreatment value. A successful outcome was defined that as more than 50% improvement of
VAS at six months.
Results The mean age was 51.5years. The success rate was 72% (16/22) after six months of follow-up. PRF induced complication were not observed. However, prognostic factors for the successful outcome was not detected between success and fail
group.
Conclusions Our results do not permit a comparison with the results of conventional radiofrequency for the same procedure.
However, PRF on cervical DRG for cervical radiating pain is effective and safe treatment option. |
