case_images: Lateral sitting and standing x-rays in the past and during this evaluation were reported to have no fractures (Fig. 1a). Due to the clinical picture, a MRI coccyx was obtained, which revealed increased marrow edema consistent with stress reaction from healing fracture or contusion (Fig. 1b).
case_images: (a) Initial posterior dissection of the coccyx with free space left by removal of free fragment from previous fracture (white arrow). (b) Close up of removed free fragment.
