WBCT Indications Series: Lisfranc

Lisfranc Injuries

A Lisfranc injury is characterized by an injury to the ligament that connects the medial cuneiform with the 2nd metatarsal base (Lisfranc ligament). Often, there are associated midfoot fractures. Unstable Lisfranc injuries left untreated can result in chronic pain and progressive collapse of the midfoot.

A weight bearing CT scan can:

  • Better characterize bony injuries​1.
  • Evaluate the 3D Lisfranc joint complex under physiologic load.
  • Identify subtle Lisfranc injuries by effectively differentiating between stable and unstable Lisfranc injuries2.


The diagnosis of Lisfranc injuries may be challenging on plain radiographs alone. A bilateral WBCT scan can be used to compare the injured to the uninjured side to detect subtle widening between the medial cuneiform and 2nd metatarsal base. A WBCT scan may also provide additional information about concomitant injuries and fractures.​

Treatment Planning

WBCT can help determine if the injury pattern is more amenable to open reduction internal fixation (ORIF) or arthrodesis. ​

It can also be utilized to evaluate the 1st, 2nd, and 3rd tarsometatarsal (TMT), intertarsal, and intermetatarsal joints for instability and fractures.

Postoperative Assessment

For postoperative assessment of operative treatment of Lisfranc ligament injuries, a WBCT can:

  • Accurately assess adequacy of reduction3​.
  • Accurately assess for any residual midfoot instability or persistent gapping between the medial cuneiform and 2nd metatarsal base​4.
  • Accurately assess healing of TMT joint fusions5.

Subtle Lisfranc Ligament Injury

40 yo female with low energy foot injury who presents with midfoot pain. Radiographs were indeterminate. ​

WBCT scan demonstrated widening between the medial cuneiform and second metatarsal base (red line).


There were no fractures identified on the WBCT. She underwent ORIF of her Lisfranc injury.

Post-Op Assessment

34 yo male who suffered a motor vehicle accident four years ago presented with midfoot pain. He underwent midfoot fusion to address his instability.


​A postoperative WBCT scan demonstrated adequate reduction and fusion of the naviculocuneiform, 1st TMT, 2nd TMT, and intercuneiform joints.​
