The PEEK Interference Screw is a state-of-the-art implant used for secure and efficient graft fixation inside a bone tunnel. Crafted from a high-performance PEEK polymer, the PEEK Interference Screw is radiolucent, which allows for clear visualization of the healing process on postoperative imaging without artifacts. The screw's specialized thread design provides a strong compression of the graft against the bone, ensuring immediate and robust fixation. As a manufacturer of cutting-edge arthroscopy products, TOOLMED designed the PEEK Interference Screw to provide a reliable solution for various ligament and tendon reconstruction procedures, leading to a faster and more predictable patient recovery.

Product Description
The PEEK Interference Screw is made from a high-performance polymer that is radiolucent, minimizing artifacts on CT and MRI scans and allowing for clear postoperative imaging.
The threaded design of the PEEK Interference Screw provides powerful compression of the graft against the bone tunnel walls, ensuring immediate and strong fixation that is critical for the success of reconstructive procedures.
The PEEK material's modulus of elasticity is similar to cortical bone, which helps to reduce stress shielding and promote the healing of the reattached soft tissue.
The PEEK Interference Screw is available in various thread designs to provide optimal grip and secure fixation in different bone qualities and applications.
The PEEK Interference Screw is indicated for the fixation of soft tissue or bone-tendon-bone grafts in ACL (Anterior Cruciate Ligament) reconstruction.
The PEEK Interference Screw is also used for the fixation of grafts in PCL (Posterior Cruciate Ligament) reconstruction.
It is suitable for the fixation of other ligaments and tendons inside bone tunnels, such as in collateral ligament reconstruction.

The PEEK Interference Screw is a specialized orthopedic implant used to secure a ligament or tendon graft within a bone tunnel. It is named for its function of "interfering" with the space between the graft and the bone, compressing the graft against the tunnel walls for immediate fixation. Made from a high-performance PEEK polymer, the PEEK Interference Screw provides the advantages of radiolucency and a modulus of elasticity similar to bone, making it a superior choice for many reconstructive procedures.
The primary application of the PEEK Interference Screw is in arthroscopic ligament reconstruction, most commonly ACL reconstruction. The PEEK Interference Screw can be used on both the femoral and tibial sides to secure a soft tissue or bone-tendon-bone graft. Its ability to provide robust fixation and its radiolucent properties also make the PEEK Interference Screw a valuable tool in PCL reconstruction and other ligament and tendon repairs.
The PEEK Interference Screw offers several key advantages for both the surgeon and the patient. Its radiolucency allows for clear postoperative visualization of the bone tunnel and the healing process without the "starburst" artifact seen with metallic screws. The PEEK Interference Screw provides an immediate, rigid fixation that allows for early rehabilitation. The biocompatible PEEK material is non-resorbable, ensuring long-term fixation, while its elasticity helps to promote bone-graft integration and reduce stress shielding.
The biomechanics of the PEEK Interference Screw are based on the principle of a secure interference fit. After the graft is positioned inside the bone tunnel, the PEEK Interference Screw is carefully advanced into the space between the bone and the graft. The screw's threads compress the graft tightly against the tunnel walls, creating a powerful friction fit that resists pull-out forces. This fixation is immediate and rigid, providing the stability necessary for the tendon or ligament to heal to the bone. The PEEK Interference Screw maintains its structural integrity over time, ensuring long-lasting fixation.
The surgical technique for implanting the PEEK Interference Screw is well-established. After the bone tunnels are drilled and the graft is prepared, the graft is pulled into the appropriate position within the tunnel. A guide pin is then used to direct the PEEK Interference Screw into the space between the graft and the tunnel wall. The screw is carefully rotated until it is fully seated, achieving a strong interference fit. The procedure is simplified by the screw's design, which provides tactile feedback to the surgeon.
Following the implantation of the PEEK Interference Screw, postoperative care focuses on a structured rehabilitation protocol. Due to the immediate and secure fixation provided by the PEEK Interference Screw, patients are often able to begin early weight-bearing and range of motion exercises as prescribed by the surgeon. Regular clinical and imaging follow-up appointments are essential to monitor graft healing and ensure the implant remains stable throughout the recovery process.
The PEEK Interference Screw is a highly effective and innovative implant for ligament and tendon reconstruction. Manufactured by TOOLMED, its advanced material and proven design provide surgeons with a powerful tool for achieving superior graft fixation. The PEEK Interference Screw contributes to enhanced biomechanical stability, excellent postoperative imaging, and a faster, more complete recovery for patients, making the PEEK Interference Screw a top choice for modern arthroscopic procedures.
