4.0mm Cannulated Screw
The 4.0 mm Cannulated Screws are part of the DePuy Synthes Cannulated Screw System. The screws are available in short and long thread, and stainless steel and titanium.
Features & Benefits
- Cannulated shaft accepts 1.25 mm diameter guide wires (threaded and non-threaded wires available).
- Hemispherical head ensures optimal annular contact with washers and DePuy Synthes plates when screws are angled.
- Low-profile head reduces possibility of soft tissue irritation.
- Standard 2.5 mm hexagonal drive is compatible with screwdrivers in other commonly used DePuy Synthes sets.
- Reverse-cutting flutes assist in screw removal.
- Choice of thread lengths offers best fit of threads into far bone fragment, for greater interfragmentary compression.
- 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.
- Self-drilling, self-tapping screw tip facilitates screw insertion by eliminating the need for predrilling and tapping in most cases.
Short thread(thread length = 1/3 screw length)
Long thread(thread length = 1/2 screw length)
