ActivaScrew™ Interference TCP - Biocomposite interference screw
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.
Patented Self-Locking SL™ technology provides implant diameter expansion of 1-2 % in human conditions. With grafts, this gives extra security for the surgeon as screw pushes graft tighter to the drill canal during the postoperative period for at least 8 weeks.
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 with wide selection of different sizes. The bioresorbable implant is cannulated, allowing easy insertion along the guidewire (K-wire). High Strength properties offer easy insertion and safe medical use without the need for removal operation.
The product is MR safe.
