摘要

The screw (1) has a lower end (14) including a face in which a diametrical groove (16) is arranged, where the groove is adapted to overlap a part of a rigid bar (3). The lower end is arranged opposite to the bar after screwing. The bar connects bone implants (2) using connection elements, where the implant includes a distal part (20) including a threaded rod arranged to be implanted in a vertebrate and a proximal part (21) having a piece comprising another diametrical groove (24). An independent claim is also included for a connection element for a vertebral column straightening and stabilization device, comprising a bolt pierced with a blind hole.
