An evaluation of two different methods of coccygectomy in patients with traumatic coccydynia.

PURPOSE: The aim of this study was to evaluate the results of partial and total coccyx excisions in patients with traumatic coccydynia resistant to conservative treatment.

PATIENTS AND METHODS: The study included 22 patients (from a total of 27) who underwent partial or total coccygectomy because of persistent coccydynia between December 2007 and January 2014. There were 15 females and 7 males with a mean age of 33.6 years (range 23-46 years). Partial coccygectomy was performed in 14 patients and total coccygectomy in 8. They were evaluated according to their pre- and postoperative visual analog scale (VAS) scores. The mean follow-up period was 28 months (range 16-48 months).

RESULTS: The mean VAS scores in the total excision group were 8.88±0.64 preoperatively and 2.5±2.67 at the final postoperative follow-up examination. In the partial excision group, these values were 8.79±0.89 preoperatively and 2.5±2.85 postoperatively. No statistically significant difference was determined between the two groups with respect to the mean scores ( p >0.05). No rectum injury was seen in any patient. When the VAS scores of the patients were evaluated as a whole, excellent and good results were obtained in 78%. Patient satisfaction with the operation was 90%.

CONCLUSION: Coccyx excision is a successful treatment method in patients with long-term coccydynia who are resistant to conservative treatment. Two different surgical methods can be applied in the treatment and both of them have low complication rates and high patient satisfaction.
