Overview

Designed in conjunction with Lawrence Fallat, DPM, J. Robert Faux, MD, and Nirmal Tejwani, MD, the Lisfranc plating system provides fixation for Lisfranc fractures-dislocations and fusions of the articulation between the first, second, and third metatarsal bones, and the cuneiform bones. This system offers the most complete selection of plates for a dorsal, dorsomedial and medial approach. The plate design allows for compression and stabilization of the TMT joint while allowing surgeons to visualize the affected area during the healing process.

Plate Families

The Lisfranc plating system is used with the ExtremiLock Foot plating system screws and instrumentation. The instrumentation was designed to assist with soft tissue management, bone and plate manipulation as well as screw insertion. All threaded holes accept 2.7 mm, 3.5 mm and/or 4.0 mm locking and nonlocking screws for patient specific fixation.

• 1st—2nd Dorsal Plates, Left & Right Specific: Bridge plating preserves joint surfaces. Multiple fixation points increase construct stability. Multiple points of fixation on the metatarsal provide larger load distribution, excellent screw purchase on diaphyseal bone and help minimize metatarsal stress fractures
• 2nd—3rd Dorsal Plates, Left & Right Specific: Visualization window allows for visualization of the TMT joint during the healing process. Distal compression hole options providing 1—2 mm of compression across the TMT joints.
• Stabilization Plates, Left & Right Specific: 1st TMT Bridge allows room for interfragmentary screw placement and/or flexible fixation implant.
• Dorsomedial Plates, Left & Right Specific: Dorsal Bridge provides stable fixation between the middle and medial column for isolated TMT joint injuries. Distal hole trajectory allows the use of interfragmentary screws and/or flexible fixation implant for intermetatarsal instability fixation. Tapered distal tip and anatomic low profile design eases percutaneous insertion and minimizes soft tissue irritation.
• Universal Medial Plate: Distal hole trajectory allows the use of interfragmentary screws and/or flexible fixation implant for intermetatarsal instability fixation. Joint alignment laser mark facilitates plate positioning

Trays

The ExtremiLock Foot System tray features a modular design. Offering eight plate modules, three screw caddies and general instrumentation. The Lisfranc plating modules are housed within the ExtremiLock Foot plating system tray. One module contains the 1st-2nd, 2nd-3rd ray plates and dorsomedial plates. The second module contains the stabilization plates, medial plates, *2.7 mm locking and nonlocking screws, *3.5 mm nonlocking screws (32 mm—60 mm) and targeting guide. Instrumentation and the 3.5 mm and 4.0 mm screws required to implant the Lisfranc plates are housed within the ExtremiLock Foot system tray.

Targeting Guide

The system provides a unique Lisfranc targeting guide that facilitates accurate Lisfranc screw fixation placement and trajectory for cases presenting with intermetatarsal instability. The guide is incredibly versatile, compatible with a wide range of screw sizes and types, making it the ideal instrument for any surgical situation.

Screw Features

Variable Angle Locking & Nonlocking Screw: The ExtremiLock Foot Plating System features double lead screw technology and provides surgeons with a broad range of screw fixation options. All screws are made from titanium alloy and include 2.7 mm, 3.5 mm and 4.0 mm cortical locking and nonlocking screws.
