Coccygectomy for stubborn coccydynia

【Abstract】Objective: To evaluate the preliminary clinical outcomes of coccygectomy in patients with coccydynia after a failure of conservative treatment. Methods: From May 2002 to January 2010, 31 patients with coccydynia were treated by coccygectomy in our department after conservative measures had failed to produce significant relief. A questionnaire, which included the extent of relief in the painful area, improvement in quality of life, intensity of pain in the sitting position, and pain score during daily activities, was used to evaluate the results. Results: All patients were followed up for 1 to 6 years (mean 3.3 years). The results were excellent in 20 patients (64.5%), good in 7 patients (22.6%), moderate in 3 patients (9.7%) and poor in 1 patient (3.2%). The excellent and good rates amounted to 87.1%. All patients except one had complete resolution of their symptoms and were subjectively highly satisfied with the outcomes of the surgery. Only 2 cases of superficial infection were observed postoperatively. Conclusion: Coccygectomy is a feasible management option for patients with coccygodynia that has no response to conservative treatments. Key words: Coccyx; Pain; Surgical procedures, operative
