The MAGNEZIX® IFSC as a bioabsorbable interference screw is used in the context of cruciate ligament reconstructions for the fixation of soft tissue or bone-tendon grafts in the press-fit technique in the tibia or femur.
A complete homogeneous conversion (transformation) of the implant to the body's own tissue (bone) takes place. This complete transformation of the implant makes subsequent metal removal unnecessary. The mechanical properties are very similar to those of human bone (high stability and elasticity) - and significantly better than those of conventional resorbable implants. In addition, magnesium stimulates bone growth osteoconductively, has an infection-inhibiting effect and is particularly well tolerated; allergies are not known.
The surface of MAGNEZIX® IFSC implants is converted to a dense, porous as well as firmly adhering magnesium-based oxide layer. The refined marginal zone acts as a passivating protective layer and is completely bioabsorbable. The resulting significant delay of the degradation process ensures the required integrity of the implant even over an extended period of time.
Optimal mechanical properties reduce the risk of screw fracture during implantation. The strength of the MAGNEZIX® material enables the interference screws to be screwed in securely without the need to perform a thread cut.
The hexagonal design ensures optimum torque transmission. An implemented self-holding mechanism facilitates safe and stable insertion of the interference screws.
Universal head geometry
The optimised screw head design makes the interference screws suitable for both tibial and femoral fixation of grafts.
Optimised thread design
The rounded thread geometry ensures that the graft is not damaged when the screw is inserted. The implants are suitable for the fixation of soft tissue as well as bone-tendon grafts.
