The benefits of using ActivaScrew™

Product information
The ActivaScrew™ is constructed of bioabsorbable lactic/glycolic acid copolymer (PLGA) These polymers have a long history of safe medical use and they degrade in vivo by hydrolysis into alpha-hydroxy acids that are metabolized by the body. The manufacturing process generates the high initial mechanical strength and stiffness of the screws.
Special characteristics of the Bioretec screw is auto-compression, lengthwise contraction of the screw by 1-2%, and related expansion in the diameter of the screw. This memory effect, based on mechanical activity, both creates compression on the fracture line and prevents the screw from loosening as metal screws commonly do. The fixation achieved with the ActivaScrew™ improves by itself over a first postoperative weeks. Bioretec’s LAG ActivaScrew™ is the only bioabsorbable screw offering controlled long-term compression on the healing fracture.
The ActivaScrew™ is durable and conforms to the bone’s own mechanical motion. The mechanical properties of the screw are fitted to those of the bone, so that together they can create an optimal healing environment and a situation in which the strain is gradually taken over by the bone from the implant as the fracture heals and the strength of the implant decreases. The screw can be used similarly to a metal screw, but in addition it offers a number of solutions and benefits that metal screws and other bioabsorbable implants cannot provide. For example, it is possible and very easy in surgery to cut the screw or modify its head during the operation if necessary. This kind of intraoperative tailoring is impossible with metal screws and more limited in other bioabsorbable products.
Compatible with AO standards
Bioretec’s threaded and LAG screws are compatible with AO standards, which surgeons are accustomed to using when working on small bones. ActivaScrew™ types include fully threaded screws, LAG screws and cannulated screws. There is a wide variety of sizes, so they are suitable for diverse indications around the body.
The fully threaded and LAG ActivaScrews™ are compatible with AO instrumentation, so no extra implantation instruments are needed.
Bioretec`s product concept
Bioretec has developed a product concept that allows for the aseptic use of a bioabsorbable product in the operating theatre. The concept facilitates and speeds up the surgeon’s work while also optimizing safety. The ActivaScrew™ is delivered with an AO-compatible single-use adapter in a specifically designed holder that permits the aseptic use of the product and offers a safe and user-friendly way to attach the screw to an instrument and transport it to the operating target.
Bioretec’s ActivaScrew™ is a fourth-generation bioabsorbable implant. Its properties are unique and proven to be top-quality. Using the ActivaScrew™ allows surgeons to attend to more patients, as removal surgery is no longer needed and time is saved during the operation itself by the advanced product technology.
