Biocompatible Interference Resorbable Screw

    Osteotwin™ was designed to fulfill two core aims: provide appropriate mechanical properties necessary for ligament reconstruction whilst ensuring a regulated resorption and osteointegration to form architectural bone through hydrolysis*.

    Canulated Resorbable Screw Design

    The thread is specific to each screw diameter so as to systematically provide the maximum amount of contact between implant and bone.

    Polylactic Resorbable Screw Range

    Made of PLDLLA, Osteotwin™ Polylactic Resorbable Screw provides great mechanical resistance, due to Poly(L-Lactide).

    Composite Resorbable Screw Range

    75% PLDLLA & 25% BCP: the convenient ratio between the necessary mechanical resistance for the indication and the faculty to generate bone growth


    • Knee Cruciate ligament reconstruction: attachment of soft tissue grafts or bone-tendon-bone grafts to the tibia and/or femur

    The fixation provided by the device is temporary and the device cannot support weight-bearing or other exertion until complete bone consolidation takes place. Pre and perioperative procedures, especially the knowledge of surgical techniques as well as the selection and proper implantation of the device, are important elements for the successful use of this device. Pre and perioperative procedures must be conducted by a competent surgeon. Patients must be informed of the use of this device, the contra-indications, and the possible adverse effects. Internal fi xation devices should never be reused, even if they appear to be intact. Any decision to remove the device must take into account the potential risk for the patient in case of a second procedure. Removal of the implant must be followed by an adequate postoperative therapy. Follow the directions for implantation and use appropriate instruments to introduce the device into the graft site. Since composite screws are transparent, they do not affect MRI. The product has not been tested on pregnant women. The risk to health has not been established.

    • ISO 13485
    • Read instructions for use for a complete list of warnings, precautions, possible adverse events and other important medical information.
    • Osteotwin™ is supplied sterile and CE-marked as a Class III Medical Device according to Directive EEC/93/42

    CE 0123
