Outcomes included Numeric Rating Scale-sitting (NRS-sitting), sitting tolerance, and Patient Global Impression of Change (PGIC) over 8 weeks.Results: Feasibility endpoints were met with no complications. NRS-sitting decreased from 6.33\u00b11.23 to 2.17\u00b10.72 at week 8 (95% CI: 1.71\u20132.63; p&lt;0.001). At week 8, 58.3% of patients could sit for &gt;30 minutes, and 75% reported high satisfaction (PGIC scores of 6 or 7). Findings should be interpreted as preliminary feasibility and short-term clinical outcomes of the staged intervention algorithm.Conclusion: These preliminary findings suggest that a staged ultrasound-guided approach incorporating PRF is feasible and safe for refractory coccydynia, with short-term improvements in pain and functional sitting tolerance reflecting the overall staged protocol rather than the isolated effect of PRF. Larger randomized controlled trials with longer follow-up are required to determine clinical efficacy, long-term durability, and the incremental contribution of PRF.<\/jats:p>","DOI":"10.11152\/mu-4649","type":"journal-article","created":{"date-parts":[[2026,9,24]],"date-time":"2026-09-24T09:31:26Z","timestamp":1790242286000},"source":"Crossref","is-referenced-by-count":0,"title":["Feasibility and early clinical outcomes of ultrasound-guided coccygeal nerve pulsed radiofrequency in refractory post-traumatic coccygodynia"],"prefix":"10.11152","author":[{"given":"Sefa","family":"Tan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Banu Gokcen","family":"Tan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruhiye","family":"Resili","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sema Tuncer","family":"Uzun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"4840","published-online":{"date-parts":[[2026,9,22]]},"container-title":["Medical Ultrasonography"],"original-title":[],"link":[{"URL":"https:\/\/www.medultrason.ro\/medultrason\/index.php\/medultrason\/article\/viewFile\/4649\/2746","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.medultrason.ro\/medultrason\/index.php\/medultrason\/article\/viewFile\/4649\/2746","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,9,24]],"date-time":"2026-09-24T09:34:33Z","timestamp":1790242473000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medultrason.ro\/medultrason\/index.php\/medultrason\/article\/view\/4649"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,9,22]]},"references-count":0,"URL":"https:\/\/doi.org\/10.11152\/mu-4649","relation":{},"ISSN":["2066-8643","1844-4172"],"issn-type":[{"value":"2066-8643","type":"electronic"},{"value":"1844-4172","type":"print"}],"subject":[],"published":{"date-parts":[[2026,9,22]]}}}
