title: Four cases of coccygeal disk calcification after cortivazol injection.
abstract: Chronic coccydynia can be treated with a glucocorticoid injection into the pain-causing intercoccygeal disk. We report four cases of calcifications within intercoccygeal disks previously injected with cortivazol. In two patients, the calcifications probably caused additional pain. Prednisolone acetate should be preferred over cortivazol for intercoccygeal disk injections.
