Definitions

  • FIG. 2A shows a side view of a fixation device according to an aspect of the invention.
  • FIG. 3 shows a side view of a fixation device according to another aspect of the invention.
  • the interlocking screw system comprises a cannulated main screw (100) and a locking screw (110) as shown in Figs. 1A-B.
  • the cannulated main screw (100) includes a body portion (101) having an outer surface with a cylindrical shape along a longitudinal axis and a transverse hole (102) aligned transverse to the longitudinal axis for accepting a locking screw, wherein an outer surface of at least a distal portion (103) of the of the body portion is threaded.
  • the drive must not obscure the cannula (107) of the main screw (100).
  • a hex drive is preferable in that the surfaces of the drive are positioned on the periphery of the drive allowing clear access to the cannula of the screw (100).
  • the cannulated main screw may be reinforced or strengthened by selecting appropriate materials, or geometry of the screw itself.
  • the cannulated main screw may be made from a titanium alloy. It should be understood a screw made from a stronger material may have a smaller diameter than a screw made from standard materials, e.g., stainless steel.
  • the internal walls of the screw may also be reinforced by coating or plating with a stronger material.
