ABSTRACT:
A vertebral locking and retrieving system includes a plurality of horizontal locking and retrieving member sets, a plurality of vertebral locking members, a plurality of connecting member sets, and a central locking rod. Each of the horizontal locking and retrieving member sets is composed of a locking rod retainer and two locking member retainers fastened respectively to two opposite sides of the locking rod retainer. Each of the vertebral locking members has one end for locking a vertebra and another end fastened to one of the locking member retainers. The connecting member sets are used in fastening the vertebral locking members to the locking member retainers and in fastening the central locking rod to the locking rod retainer. A horizontal locking of a vertebra is achieved by the horizontal locking and retrieving member sets while a longitudinal locking of the vertebra is attained by the central locking rod connecting the horizontal locking and retrieving member sets.
