Efficacy of Combining Caudal Epidural Steroid With Ganglion Impar Block in Chronic Coccydynia

Condition(s) studied

Study 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.

Eligibility

Primary outcome measure(s)

• Change in NRS-11 pain score from baseline to 6 months — Baseline and 6 months post-procedure
  Within-participant change in pain intensity (ΔNRS = 6-month NRS-11 minus baseline NRS-11); negative values indicate improvement. NRS-11: 0=no pain, 10=worst pain.
