A Comparative Retrospective Study of the Efficacy of Caudal Epidural with Manipulation Versus Ganglion Impar Block with Manipulation in Patients with Coccydynia

Objective: The objective of the study was to compare the effectiveness of caudal epidural with manipulation and ganglion impar block with manipulation in treating patients with coccydynia. Materials and Methods: In this retrospective study, patients (n = 60) were divided into two groups of 30 each. Group C (n = 30) received caudal epidural with transrectal manipulation, whereas Group G (30) received ganglion impar block with transrectal manipulation. Preprocedural and procedural Visual Analog Scale (VAS) scores for 10 days, 1, 3, and 6 months were recorded. Preprocedural painless sitting period and postprocedure painless sitting period in two groups were recorded. Results: Preprocedural VAS score was not statistically significant between the two groups (7.76 ± 0.63 vs. 7.6 ± 0.72; P = 0.16). There was no statistically significant difference in the VAS score after 10 days of the procedure in both the groups. Significant decrease in VAS score was observed in Group G than in Group C after 1, 3, and 6 months of the follow-up. The painless sitting period was increased in Group G than in Group C after 6 months of follow-up (79.33 ± 48.4 min vs. 144.16 ± 37.87 min; P < 0.0001). Recurrence was observed in six patients in Group C. No significant complications were observed in both the groups. Conclusion: Ganglion impar block with manipulation is more effective in improving pain sensation and painless sitting period in patients with coccydynia.
