Pulsed radiofrequency of dorsal root ganglion (PRF\u2013DRG) treatment is known to be effective in alleviating CLRP. This retrospective study compares the efficacy of a single CT-guided PRF\u2013DRG procedure in the treatment of unilateral CLRP between patients without (non-PSS) and with (PSS) previous lumbar spine surgery. Non-PSS and PSS groups included 30 and 20 patients, respectively. Outcomes (pain intensity and disability) were evaluated by means of the visual analog scale (VAS) and Oswestry disability index (ODI) immediately after the procedure (VAS), as well as three and six months after the procedure, respectively. Non-PSS group showed a significant (p \u02c2 0.001) decrease of VAS (median) at all follow-up intervals (from 6 to 4; 4; 4.5 points, respectively). The PSS group showed a significant yet transient VAS (median) decrease (from 6 to 5 points) immediately after the procedure only (p &lt; 0.001). The decrease of VAS was more pronounced in the non-PSS group after three and six months (p = 0.0054 and 0.011, respectively) in intergroup comparison. A relative decrease of VAS \u2265 50% during follow-up was achieved in 40%; 43.3%; 26.7% (non-PSS), and 25%; 5%; 0% (PSS) of patients. ODI (median) significantly decreased in the non-PSS group (from 21.5 to 18 points) at three and six months (p = 0.014 and 0.021, respectively). In conclusion, previous lumbar spine surgery decreases the therapeutic efficacy of PRF\u2013DRG procedure in CLRP patients.<\/jats:p>","DOI":"10.3390\/jpm13071054","type":"journal-article","created":{"date-parts":[[2023,6,27]],"date-time":"2023-06-27T01:42:02Z","timestamp":1687830122000},"page":"1054","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Previous Lumbar Spine Surgery Decreases the Therapeutic Efficacy of Dorsal Root Ganglion Pulsed Radiofrequency in Patients with Chronic Lumbosacral Radicular Pain"],"prefix":"10.3390","volume":"13","author":[{"given":"Jiri","family":"Jandura","sequence":"first","affiliation":[{"name":"Department of Diagnostic Radiology, University Hospital Hradec Kralove, Sokolska 581, 50005 Hradec Kralove, Czech Republic"},{"name":"Department of Diagnostic Radiology, Faculty of Medicine in Hradec Kralove, Charles University, Simkova 870, 50003 Hradec Kralove, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0064-8814","authenticated-orcid":false,"given":"Milan","family":"Vajda","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology, University Hospital Hradec Kralove, Sokolska 581, 50005 Hradec Kralove, Czech Republic"},{"name":"Department of Diagnostic Radiology, Faculty of Medicine in Hradec Kralove, Charles University, Simkova 870, 50003 Hradec Kralove, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roman","family":"Kostysyn","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology, Faculty of Medicine in Hradec Kralove, Charles University, Simkova 870, 50003 Hradec Kralove, Czech Republic"},{"name":"Department of Neurosurgery, University Hospital Hradec Kralove, Sokolska 581, 50005 Hradec Kralove, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiri","family":"Vanasek","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology, University Hospital Hradec Kralove, Sokolska 581, 50005 Hradec Kralove, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eva","family":"Cermakova","sequence":"additional","affiliation":[{"name":"Department of Medical Biophysics, Faculty of Medicine in Hradec Kralove, Charles University, Simkova 870, 50003 Hradec Kralove, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8035-0144","authenticated-orcid":false,"given":"Jan","family":"Zizka","sequence":"additional","affiliation":[{"name":"Department of Imaging and Functional Medicine, University of Umea Daniel Naez\u00e9ns v\u00e4g, 90737 Umea, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7793-0375","authenticated-orcid":false,"given":"Pavel","family":"Ryska","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology, University Hospital Hradec Kralove, Sokolska 581, 50005 Hradec Kralove, Czech Republic"},{"name":"Department of Diagnostic Radiology, Faculty of Medicine in Hradec Kralove, Charles University, Simkova 870, 50003 Hradec Kralove, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"477","DOI":"10.36076\/ppj.2014\/17\/477","article-title":"Effectiveness of pulsed radiofrequency with multifunctional epidural electrode in chronic lumbosacral radicular pain with neuropathic features","volume":"17","author":"Vigneri","year":"2014","journal-title":"Pain Physician"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"325","DOI":"10.1093\/brain\/117.2.325","article-title":"Epidemiology of cervical radiculopathy.
