A cortical screw is a bone fixation screw for dense, compact cortical bone. Surgeons use it to stabilize fracture fragments, secure bone plates, and support compression fixation in orthopedic and trauma procedures.
Cancellous screws carry deeper threads for softer, spongier bone. A cortical fixation screw works differently. It features a shallower thread depth and a finer pitch. This design suits the hard, uniform structure of cortical bone. The screw needs strong contact along its full length, not deep purchase in one area. As a result, this bone fixation screw threads along its entire shaft. It engages consistently wherever it crosses the cortex.
This orthopedic fixation screw commonly serves diaphyseal fracture repair, plate-to-bone fixation, and interfragmentary compression. In compression fixation, the screw draws bone fragments together across a fracture line. Cortical bone carries most of a long bone’s structural strength. Precise thread engagement in this layer directly affects how securely an implant construct holds during healing.
Available Specifications
- Diameters: 1.5 mm, 2.0 mm, 2.7 mm, 3.0 mm, 3.5 mm, 4.0 mm, 4.5 mm
- Lengths: 6 mm to 60 mm in standard increments, plus 65 mm to 110 mm in 5 mm increments
- Materials: premium German stainless steel and titanium
Material Options
Buyers can choose premium German stainless steel for widely used, cost-effective fixation. Titanium suits cases where reduced weight and biocompatibility matter most. Both materials follow the same dimensional specifications listed above. Switching between them does not change the available sizing.
Overall, this cortical screw gives surgical teams a configurable option. Diameter, length, and material choices span a range of bone fixation needs. Exact size availability can vary by combination, so buyers should confirm specific diameter-length pairings before ordering.
