Abstract
The present invention relates to a bone fixation device () for securing attachment between a screw and a vertebra comprising two pedicles, comprising a hollow cavity having a longitudinal axis, a distal part () having itself a distal end and () a proximal end (), a proximal part () having itself a distal end () and a proximal end () and a flange at the proximal end (), characterized in that: —the distal part () comprises a deformable area (D) comprising at least three helical slots (); and—the distal part () comprises a full portion () located distally after said at least three helical slots (); further characterized in that said full portion () cooperates with the screw such that once the screw abuts against the flange () of the bone fixation device (), further screwing causes the deformation of the deformable area (D) of the distal part () and the retraction of the distal end of the distal part () towards the proximal end of the distal part (); and in that after screwing, the borders of each at least three helical slots () abuts against each other.
