The Tenodesis Screw System eliminates transosseous tunnels in tendon repairs and ligament reconstructions. Tenodesis screws may be used in conjunction with #2 or 2-0 FiberWire® or FiberLoop® sutures to facilitate intraoperative tissue tensioning and fixation in a predrilled socket. The predrilled socket minimizes incision length, dissection, and overall morbidity.1 BioComposite or vented PEEK screw insertion provides superior and immediate fixation for foot and ankle indications such as Achilles repair, FDL and FHL tendon transfers, and lateral ligament stabilization.2-4 The system can also be used for applications in the hand and elbow (UCL, LRTI, distal biceps) and the shoulder (rotator cuff repair, proximal biceps), as well as for collateral ligament repair, reconstruction, and secondary graft or suture fixation for ACL/PCL reconstruction. This construct allows for direct tendon-to-bone healing, without hardware prominence.
In addition, the tension-slide technique with the FDL and FHL Implant Systems can be used for FDL and FHL anterior tibialis and posterior tibialis tendon transfers. Using cortical button fixation and a tenodesis screw allows for maximum tendon-to-bone contact, a low-profile fixation, and the ability to independently tension the graft, with less need for long tendon harvest and less dissection.
