网页2023年5月1日 · Magnetic resonance imaging (MRI) can be used to assess the anterior curvature of the coccyx, the fusion of the sacrococcygeal and intercoccygeal joints, as well as the presence of a distal coccyx bone spicule (spur). These anatomical findings can either be a precipitant or a consequence of coccydynia.
