Preface Dear Colleagues: Despite the introduction and evolution of a wide variety of thoracolumbar rod and screw systems, the spine surgeon still faces many challenges in the operative care of patients requiring segmental Spinal instrumentation for trauma, deformity, tumor, and major degenerative instabilities. The ability of ONE thoracolumbar rod and screw System to safely manipulate Spinal segments, reduce the rod to the screw or hook in a controlled manner, and correct significant deformities while maintaining strong implant/bone fixation has been lacking.

5 We believe that the TSRH SILO Spinal System provides spine surgeons with a posterior fixation System with biomechanically-proven strength, flexibility, and ease of use, thus enabling the surgeon to efficiently deal with the severest of Spinal pathology. The side-opening and top-tightening aspects of the TSRH SILO Spinal System screws and hooks are designed primarily to simplify and enhance reduction capability in the high-demand . situation where deformity, due to trauma or other etiologies, provides significant reduction and fixation difficulties.

6 Furthermore, we believe that the single-handed operation of the Rock-N- Roll Reducer and the flexibility of the Sagittal Adjusting Screw will facilitate the intraoperative reduction of the screw to the rod and will minimize the stresses that occur at the screw/bone interface during these reduction maneuvers. We are optimistic and excited about the simplicity, versatility, and innovative capabilities of this new System that is targeted to provide intraoperative benefits to both the surgeon and the patient. It is our sincere hope that as we have, you will also be able to experience these benefits.

Features and Benefits Sagittal Adjusting Screw (SAS). - Enables 25 sagittal angulation - Provides the strength and manipulation capability of a Fixed Angle Screw with the forgiveness of a Multi Axial Screw - Allows for screw positioning and rod insertion at challenging angles - Sagittal forgiveness reduces the stress on the bone/screw interface that occurs during correction maneuvers and rod seating ( , the windshield wiper effect).

8 Rod Reduction Capabilities - Simplification of rod/screw reduction even over large trajectories - Single-hand operated Rock-N-Roll Reducer effortlessly reduces the rod to the screw or hook, thus enabling dorsal and lateral reduction - Allows vertebral segment manipulation and provisional fixation by a single surgeon Provisional Rod Capture - Single closure mechanism captures the rod into the head of the implant while still allowing for screw/vertebral body manipulation (derotation at the apex of scoliosis and kyphosis correction). - Set Screws can be preloaded, therefore eliminating the possibility of cross-threading during rod capture 3.
