Efficacy of Combining Caudal Epidural Steroid With Ganglion Impar Block in Chronic Coccydynia
Turkey (Türkiye)56 participantsStarted 2020-01-01
Plain-language summary
Coccydynia refers to pain localized to the tailbone (coccygeal) region. Initial management is conservative-nonsteroidal anti-inflammatory drugs (NSAIDs), use of a seat cushion, and physical therapy-yet a proportion of patients remain symptomatic and subsequently pursue interventional options. The ganglion impar block (GIB), originally used to treat perineal cancer pain, is now recognized as an effective approach for perineal and coccygeal pain of both malignant and benign etiologies. Caudal epidural steroid injection (CESI) is also employed, either as monotherapy or in conjunction with other treatments; however, its precise role in coccydynia has not been clearly defined. Evidence directly comparing these injections is limited, and whether the combination confers superiority over GIB alone remains unresolved.
In this retrospective study, we will compare GIB alone versus GIB combined with CESI in adults treated for chronic coccydynia refractory to noninterventional management and evaluate any incremental benefit of the combination.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
