[Therapy-resistant coccygodynia should no longer be considered a myth : The surgical approach].

BACKGROUND: Coccygodynia is still often considered a mystery, and many patients are not taken seriously with their problems and pain. CASE: A 51-year-old thin lady presented at our clinic with lifelong, persistent low back pain. The clinical examination indicated suspicion of coccygodynia. A functional X‑ray revealed a hypermobile os coccygeum with dorsal tilt. After a total coccygectomy via a y-shaped approach, she was completely pain free at the 12 months follow-up examination. No surgical site infection occurred in this period.
