ActivaScrew™ Interference TCP
The range starts from the world´s smallest, strong biocomposite interference screw.
The thread profile of the ActivaScrew™ Interference TCP is round to preserve graft violation during the insertion but high enough to give proper pull-out strength. The design provides homogenous contact pressure against soft tissue graft
without harming it. ActivaScrew™ Interference TCP biocomposite screw is made of bioabsorbable self-reinforced poly(L-lactide-co-glycolide) (PLGA) mixed with β-tricalcium phosphate (TCP). The β-tricalcium phosphate is known to be an osteoconductive ceramic and has excellent biocompatibility with natural bone components. Our technology results osteoconductive TCP particles exposed on the screw surface that allows immediate initiation of the bone growth effect.
The size range starts from the small but extremely strong Ø 4 mm x 10mm, the largest being 11 mm in diameter.
High usability for various indications
Wide selection of different sizes
Easy insertion along the guide wire (K-wire)
Isoelasticity; the bending modulus is closer to the value of cortical bone compared to metallic implants
High Strength properties offer easy insertion and safe medical use
No need for removal operation
