Cannulated headless Herbert screws are selected as part of a small-fragment fixation plan. Diameter, length, fragment geometry and the planned screw trajectory must be considered together.
Understand the design
A headless compression screw is intended to minimize the profile above the bone surface. The cannulation supports placement over a guide wire, and the screw design is intended to apply compression across the prepared interface.
Compare the four diameters
- 1.7 mm: the smallest option in the current range
- 2.3 mm: a small-fragment configuration with greater diameter
- 3.0 mm and 3.5 mm: larger configurations in the same product family
- Length and thread configuration selected for the planned application
Confirm the application
The 1.7 and 2.3 mm options extend the system to smaller fragments and selected periarticular procedures. The final decision must follow the approved indication, surgeon’s plan, bone quality and fragment size.
Check the instrument set
Confirm the guide wire, drill, countersink, measurement and insertion instruments used with the selected screw diameter. Instrument compatibility is as important as the implant size.
Ordering checklist
Specify diameter, length, quantity, instrument set and destination market. The product illustrations are representative configurations and should not replace the approved surgical technique.
