Coccyx Fracture and Dislocation

  • 877 Accesses


Coccyx (tailbone) fractures and dislocations can be challenging diagnoses to confirm and treat.

Patient history often includes tailbone trauma, although some dislocations occur via gradual ligamentous instability without any history of blunt trauma. Physical examination typically reveals focal coccyx tenderness to palpation. Accurate diagnosis requires proper imaging studies, which may include X-rays (radiographs), MRI, or CT scans. Treatment may include oral medications, nasal calcitonin (for fracture pain and bone healing), and local coccyx injections under image guidance (e.g., fluoroscopy). Appropriate medical care is crucial since coccydynia (coccygodynia, tailbone pain) is at high risk for becoming a chronic source of pain and disability that can significantly impair quality of life.
