The Diplomat pedicle screw system includes two implants: the screw and the tulip. According to the surgical situation, the screw can be combined with different tulips, thus enabling different procedures for the stabilisation of the spine. The thread pitch of the screws has been designed for faster insertion and reduces the implantation time. The tulip profile is extremely low, thus guaranteeing optimum adjustment. The patented locking mechanism ensures a very high strength of the tulip-screw connection.
