Plating SystemsSilverback™ Ankle Fusion Span Plating System

The Paragon 28® Silverback™ Ankle Fusion Span Plating System provides anterior and posterior plates designed to be used in cases where a significant void is present at the ankle joint. Plates may be utilized in combination with an allograft or cage to address a bony deficit. The Span Plating System includes eight plates and allows for an anterior and posterior approaches.

A proximal compression slot built into all plates may be used to compress the bone to graft interface. All Span Plates have a single contour and are available in standard and long lengths which offer varying span distances to accommodate different allograft heights required to fill the bone void present. The relatively thinner plate helps to evenly distribute force across the construct and helps guard against stress shielding during healing.

The Posterior Span Plates accept the Silverback™ Ø4.5 mm and Ø5.2 mm screws to be used for the tibia and calcaneus. The Anterior Span Plates accept Silverback™ Ø4.5 mm and Ø5.2 mm screws in the tibia and talar body and Gorilla® R3CON Ø3.5 mm and Ø4.2 mm screws in the talar neck holes. A Ø4.7 mm “Compact” screw is available for the hole sizes in the tibia and calcaneus, which was designed with a smaller thread height to help reduce insertion torque in dense bone. Additionally, single lead bone threads result in a decreased pitch differential between the locking screw head and bone threads to reduce the amount of insertion torque required to lock the Compact screw into the plate in areas of dense bone.

All plate screws have the option to drill on-axis using the Straight / EZ Cone Guide or to drill off-axis up to 15°. The Phantom Hindfoot TTC/TC Nail should be inserted prior to the Straddle Plate placement. The relatively wider plate design accommodates the Phantom TTC/TC Nail which helps evenly distribute force across the construct and guard against stress shielding during healing.

A robust offering of joint preparation instrumentation is offered in the Silverback™ case and tray to address TT and TTC arthrodesis. Joint preparation instrumentation includes an array of cartilage removal tools, curettes, osteotomes, burrs, perforators, and bone fenestration chisels.
