Coccygectomy for Coccygodynia: A Single Center Experience Over 5 Years

INTRODUCTION: Coccygodynia refers to a pathological condition in which pain occurs in the coccyx or its immediate vicinity. The pain is usually provoked by sitting or rising from sitting. Several studies have reported good or excellent results after coccygectomy especially in patients who are refractory to conservative treatment. AIMS AND OBJECTIVES: This study aims to evaluate the role and effectiveness of coccygectomy in chronic refractory coccygodynia. MATERIALS AND METHODS: Between January 2011 and January 2015, 16 consecutive patients (4 males and 12 females) who underwent surgical coccygectomy were enrolled prospectively in the study. All patients suffered from treatment-resistant coccygodynia and had exhausted conservative therapeutic options for at least 6 months before undergoing surgery. The same surgeon performed a complete coccygectomy on all patients. Postoperative outcomes included measurements of pain relief and degree of patient satisfaction with the procedure's results. RESULTS: The average age of patient was 37.93 years (range: 25–53 years), and the male to female ratio was 1:3. The median duration of patient-reported symptoms prior to surgery was 24 months. The most common cause of coccygodynia was direct or indirect trauma, recorded in 11 patients (68.75%). Idiopathic coccygodynia was five cases (31.25%). The number of patients with outcomes rated as “excellent,” “good,” “fair,” and “poor” were 12, 2, 1, and 1, respectively. The favorable result (excellent or good) was 87.5%. The self-reported visual analog scale (VAS) was significantly improved by surgery. The mean VAS preoperatively was 9.62, and postoperatively it was 2.25 (P < 0.001). There were two infections (12.5%) among the 16 patients which were managed conservatively. CONCLUSIONS: Coccygectomy for chronic intractable coccygodynia is simple and effective, with a low complication rate.
