Lisfranc Dislocation

Lisfranc Dislocation

Lisfranc’s joint refers to the tarsometatarsal joint. Lisfranc’s ligament is a stout structure that runs from the medial cuneiform to the base of the second metatarsal. The low energy type Lisfranc injury (sprain) occurs commonly in field sports when a player’s foot is stepped on while running. High energy Lisfranc fractures/dislocations often occur in falls from a height or in head-on motor vehicle accidents.

Compression FT Screws

Compression FT Screws

The titanium Compression FT (fully threaded) screws come in 2.5 mm Micro, 3.5 mm Mini, 4.0 mm Standard, 5.0 mm Large, and 7.0 mm XL. The variable-stepped thread pitch and headless design helps reduce the risk of profile complications, provides compression, and allows for simplified insertion. Surgeons can now achieve zero-profile, stable fixation. The Compression FT family of screws now offers 5 diameters and 91 screw lengths to fit various orthopedic applications throughout the body.

Lisfranc Arthrodesis

Lisfranc Arthrodesis

Post-traumatic arthritis is a common complication following Lisfranc injury. When conservative measures fail, patients may benefit from selective arthrodesis of symptomatic joints. Arthrex provides surgeons with low-profile plates, Nitinol staples, headless compression screws, and biologic augmentation to facilitate a successful fusion.

Lisfranc Injury Fixation

Lisfranc Injury Fixation

Low energy, purely ligamentous injuries of the Lisfranc joint are difficult to detect and require a high index of suspicion due to their subtle presentation, particularly in athletes. Weightbearing radiographs, in combination with CT and MRI, may be required for proper diagnosis. Any diastasis greater than 2 mm is considered a positive for Lisfranc injury.

Traditional fixation methods using screws and/or plates provide a stable construct for the Lisfranc injury but may overconstrain the joint, resulting in the patient's inability to return to preinjury activity levels. Additionally, rigid fixation often requires a secondary surgery for hardware removal prior to full weightbearing and has the added risk of reduction loss.

Flexible fixation devices such as the 2.7 mm Knotless Mini TightRope® implant and Lisfranc Fixation System for InternalBrace™ repair overcome the shortcomings of rigid fixation and provide a strong^1,2 and reproducible construct to stabilize the Lisfranc joint.
