Abstract
A device for spinal osteosynthesis includes an elongated bar having two parallel, spaced longitudinal slots extending parallel to the bar length. The slots define a central bar branch and two side bar branches flanking the central bar branch. A plurality of fasteners extend from the bar; each fastener has a shank to be implanted; a head provided at an end of the shank; and a groove provided in the fastener head. The groove has a bottom and divides the head into two leg portions. The central bar branch is received by the groove and is in engagement with the bottom thereof. The leg portions extend through the slots and straddle the central bar branch. A nut is secured to the head of each fastener and abuts a surface of the bar for tightening the fastener to the bar.
