Pelvis/Hip Case 8 Diagnosis

Coccyx Fracture


AP and lateral x rays may reveal the injury; however, given patient variability in the number of coccygeal vertebrae (3-5), these films are often difficult to interpret. The coccyx is also difficult to fully visualize on plain films. So the sensitivity of plain films is limited. If suspicion for fracture is high enough, a clinical diagnosis is made despite nondiagnostic x rays.
