The Interface Screw System is designed for graft fixation during anterior cruciate ligament (ACL) reconstruction. It secures tendon or ligament grafts within femoral and tibial bone tunnels by compressing the graft against the tunnel wall. The system consists of a conical screw and a protective sheath designed to help protect soft tissue during insertion and maintain graft positioning. The screw is made from PEEK (polyetheretherketone), a biocompatible polymer used in orthopedic implants.
• Conical Screw Design: The tapered shape, with a larger head diameter than the tip, facilitates screw insertion.
• Star Drive Mechanism: The star-shaped drive interface is designed to support torque transmission during insertion.
• Protective Sheath: Helps shield the tendon or ligament graft from direct contact with the screw during insertion.
• Locking Mechanism: An external clamp block on the sheath helps maintain graft positioning during fixation.
• PEEK Material: Provides a biocompatible, radiolucent implant material for orthopedic applications.
• Facilitated Insertion: The conical screw design supports placement within the bone tunnel.
• Driver Engagement: The star drive interface supports controlled screw insertion.
• Graft Protection: The protective sheath helps reduce direct contact between the screw and soft tissue during insertion.
• Graft Positioning: The external clamp block helps limit graft displacement during fixation.
• PEEK Construction: Provides a polymer-based alternative to metallic fixation components.
The Interface Screw System is intended primarily for ACL reconstruction, where it is used to secure soft tissue grafts or bone-tendon grafts within the knee's femoral or tibial bone tunnels.
