High-Purity Titanium Constructs for Small-to-Medium Bone Fixation
CytroFIX® 2.7 Cortical Screws (standard and locking) by Cytronics (an INVAMED orthopedic division) are engineered to meet the demands of small-to-mid segment fracture management—commonly in the forearm (radius and ulna), distal radius, ankle (distal fibula), and selected pediatric or foot/hand procedures. These screws, crafted from high-purity titanium, combine robust fixation strength with minimal hardware prominence, making them ideal for complex fracture patterns requiring a moderate screw diameter.
Optimized 2.7 mm Diameter
- Provides an excellent balance between mechanical stability and lower-profile hardware for fractures requiring slightly more robust fixation than 2.0 mm mini-fragment screws.
- Frequent choice for forearm, small joint, or distal radius repairs, as well as certain foot/ankle indications.
High-Purity Titanium Composition
- Fabricated from medical-grade titanium alloy (e.g., Ti-6Al-4V ELI), ensuring superior biocompatibility, corrosion resistance, and an optimal strength-to-weight ratio.
- Reduces the risk of allergic reactions and fosters a favorable environment for bone healing.
Standard Cortical vs. Locking Options
- Standard Cortical Screws: Deliver traditional compression and compatibility with non-locking plate holes.
- Locking Cortical Screws: Feature threaded heads designed to engage threaded plate holes, creating a fixed-angle construct that can enhance stability in osteopenic bone or complex fracture patterns.
Low-Profile Head Geometry
- Screw heads are refined to minimize protrusion or soft tissue irritation, supporting early mobilization and reduced hardware prominence in sensitive anatomical regions.
- Available in Torx/Hexalobe driver interfaces for secure engagement and reduced risk of screw head stripping.
Versatile Clinical Applications
- Intended for small-to-mid fragment fractures of the radius, ulna, distal fibula, humeral condyles, or foot/hand bones where a 2.7 mm diameter is indicated.
- The locking variant proves beneficial in multi-fragment fractures, poor bone stock, or when used with locking plate systems for added stability.
Contraindications
- Active local or systemic infections, insufficient bone quality preventing reliable screw purchase, or patient factors contraindicating elective orthopedic procedures.
- Surgeons must confirm that a 2.7 mm diameter is appropriate based on the fracture site, patient anatomy, and the chosen plating system.
