Summary

This retrospective cohort study included 60 patients aged 18-65 years treated at a tertiary pain clinic between June 2022 and June 2024. Patients received either Ganglion Impar Block (GIB) alone or GIB combined with pericoccygeal injection in a single session under fluoroscopic guidance. Pain severity and functional outcomes were assessed using the Numeric Rating Scale (NRS-11), Oswestry Disability Index (ODI), and Paris Functional Coccydynia Impact Questionnaire (PFCIQ) before the procedure and at 1 and 3 months post-intervention.

Conditions

  • Coccydynia

Interventions

PROCEDURE

Ganglion Impar Block

The ganglion impar was accessed with a Quincke spinal needle, transsacrococcygeally (from between the first and second coccygeal vertebrae if sacrococcygeal access could not be achieved). Then, 1 mL of non-ionic contrast medium was administered, and fluoroscopic anterior-posterior and lateral imaging was performed to confirm the appropriate spread of contrast (Figure 1). After this confirmation, 2 mL of 0.5% bupivacaine, 2 mL of saline, and 40 mg of methylprednisolone acetate were injected.

PROCEDURE

Ganglion Impar Block and Pericoccygeal Injection

In the combination therapy group who underwent pericoccygeal injection in addition to impar block, following the same procedure, 5 mL of 0.25% bupivacaine and 20 mg of methylprednisolone were injected into the posterior pericoccygeal region while the needle was withdrawn, thus also targeting blockade of the anococcygeal nerve.
