Ghost sign (cervical spine)

Ghost sign is a feature that has been described in Clay shoveler fracture as can be seen on the AP projection of a cervical spine radiograph. It is caused by the appearance of a "double spinous process" on C6 or C7 resulting from caudal displacement of the avulsed spinous process fragment, giving the appearance of two smaller spinous processes, one immediately on the top of the other.
