OBJECTIVES: In the present study, we used ultrasound (US) guidance and compared the effects of monopolar PRF with those of bipolar PRF in patients with chronic cervical radicular pain refractory to repeated transforaminal epidural steroid injections. METHODS: Sixty-six patients with chronic cervical radicular pain were included in this study. Patients were randomly assigned to one of the two groups: monopolar or bipolar PRF group (n= 33 per group). Pain intensity was evaluated using a numeric rating scale (NRS) at pretreatment, and at 1 and 3\u00a0months after the treatment. Target stimulation site was the extraforaminal nerve root. RESULTS: Compared to the pretreatment NRS scores, patients in both groups showed a significant decrease in NRS scores at 1 and 3\u00a0months after the treatment. Reductions in the NRS scores over time were significantly larger in the bipolar PRF group. Three months after the treatment, 18 patients (54.5%) in the monopolar PRF group and 27 (81.8%) in the bipolar PRF group reported successful pain relief (pain relief of \u2a7e50%). CONCLUSIONS: US-guided PRF can be an effective interventional technique for the management of chronic refractory cervical radiculopathy. Moreover, bipolar PRF has better treatment outcome than monopolar PRF.<\/jats:p>","DOI":"10.3233\/bmr-201842","type":"journal-article","created":{"date-parts":[[2021,9,17]],"date-time":"2021-09-17T11:52:25Z","timestamp":1631879545000},"page":"583-588","source":"Crossref","is-referenced-by-count":3,"title":["Comparison between ultrasound-guided monopolar and bipolar pulsed radiofrequency treatment for refractory chronic cervical radicular pain: A randomized trial"],"prefix":"10.1177","volume":"35","author":[{"given":"Sang Hoon","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Radiology, Madi Pain Management Center, Jeonju, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hyun Hee","family":"Choi","sequence":"additional","affiliation":[{"name":"Madi Research and Development Center, Jeonju, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Min Cheol","family":"Chang","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Medicine, College of Medicine, Yeungnam University, Daegu, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","reference":[{"key":"10.3233\/BMR-201842_ref1","doi-asserted-by":"crossref","first-page":"315","DOI":"10.1016\/0304-3959(92)90237-6","article-title":"Cervicogenic headache: Anesthetic blockades of cervical nerves (C2\u2013C5) and facet joint (C2\u2013C3)","volume":"49","author":"Bovim","year":"1992","journal-title":"Pain."},{"key":"10.3233\/BMR-201842_ref2","doi-asserted-by":"crossref","first-page":"e398","DOI":"10.1016\/j.wneu.2017.11.014","article-title":"Outcome of transforaminal epidural steroid injection according to severity of cervical foraminal stenosis","volume":"110","author":"Kim","year":"2018","journal-title":"World Neurosurg."},{"key":"10.3233\/BMR-201842_ref3","doi-asserted-by":"crossref","first-page":"3","DOI":"10.1111\/j.1533-2500.2010.00400.x","article-title":"Bipolar radiofrequency lesion geometry: Implications for palisade treatment of sacroiliac joint pain","volume":"11","author":"Cosman","year":"2011","journal-title":"Pain Pract."},{"key":"10.3233\/BMR-201842_ref4","doi-asserted-by":"crossref","first-page":"527","DOI":"10.1097\/ALN.0b013e318182c86e","article-title":"Radiofrequency applications to dorsal root ganglia: a literature review","volume":"109","author":"Malik","year":"2008","journal-title":"Anesthesiology."},{"key":"10.3233\/BMR-201842_ref5","doi-asserted-by":"crossref","first-page":"91","DOI":"10.2147\/JPR.S29864","article-title":"Percutaneous radiofrequency lesioning of the suprascapular nerve for the management of chronic shoulder pain: A case series","volume":"5","author":"Simopoulos","year":"2012","journal-title":"J Pain Res."},{"key":"10.3233\/BMR-201842_ref6","doi-asserted-by":"crossref","first-page":"717","DOI":"10.1097\/AJP.0b013e318173c27a","article-title":"A comparison of the neuroablative effects of conventional and pulsed radiofrequency techniques","volume":"24","author":"Vatansever","year":"2008","journal-title":"Clin J Pain."},{"key":"10.3233\/BMR-201842_ref7","doi-asserted-by":"crossref","first-page":"E225","DOI":"10.36076\/ppj.2018.3.E225","article-title":"Efficacy of Pulsed radiofrequency stimulation in patients with peripheral neuropathic pain: A narrative review","volume":"21","author":"Chang","year":"2018","journal-title":"Pain Physician."},{"key":"10.3233\/BMR-201842_ref8","doi-asserted-by":"crossref","unstructured":"Chang MC, Lee DG.
