Specifications

Specifications

  • Cannulated shaft accepts guide wires of 1.2mm
  • Hemispherical head of the screws ensures optimal annular contact with washers and plates when screws are angled
  • Low-profile head reduces possibility of soft tissue irritation
  • Standard 2.5mm hexagonal drive is compatible
  • Reverse cutting flutes assist in screw
  • Choice of thread lengths offers best fit of threads into far bone fragment, for greater interfragmentary compression
  • Thread Length-
    Short thread
    (thread length = 1/3 screw length)
  • Cancellous thread profile uses deep ‘cutting threads’ with a large pitch to increase resistance to pullout. The large pitch also accelerates screw insertion and removal.
  • The partially threaded screws can be used to "lag" one bone fragment to another where the bone fragment is captured by the threads of the screw and pulled toward the fragment piece closest to the headed end of the screw.
  • Self-tapping screw tip facilitates screw insertion by eliminating the need for tapping.
  • Length ranges from 10mm-60mm with a diameter of 4.0mm.
  • Available in both Titanium and Stainless Steel
