ComposiTCP™ Interference Screw

ComposiTCP^™ Interference Screw

• Procedure-specific composite mix for both soft tissue and bone-tendon-bone grafts
• Unique star-shaped drive mechanism that limits stress and distributes torque evenly through the screw during insertion¹

ComposiTCP^™ 30 Interference Screw

• Made with a composite blend of 70% PLDLA and 30% beta Tri-Calcium Phosphate—designed for both bone-tendon-bone and soft tissue fixation

ComposiTCP^™ 60 Interference Screw
Made from a composite material with an innovative blend of 40% PLDLA and 60% beta Tri-Calcium Phosphate—designed for soft-tissue fixation.
 

The results reported in an in-vivo animal study2 showed that “in comparison with pure PLA, TCP-containing composite materials had faster degradation kinetics, caused less inflammatory reaction, and promoted contact osteogenesis.”
The ComposiTCP^™ 60 Interference Screw has more osteoconductive material than resorbable polymer. In-vitro studies1,2 have shown that increased amounts of TCP may stimulate the proliferation of osteogenous cells.
