Lisfrancs Injury of the foot

Updated: Nov 25, 2020

What is it?

The Lisfrancs ligament is a small group off ligaments that have anatomical variants of dorsal, interosseous and plantar components to stabilise the medial cuneiform bone against the distal metatarsals.

The Lisfrancs joint is more commonly referred to now as the tarsometatarsal-joint and the injury can occur in many different locations within this midfoot area.

How does it get injured?

Many different ways, unfortunately!

But a high level of force is needed to dislocate this joint and it normally happens with rapid joint movements with pronation and either a plantar or dorsiflexion of the area involved.

Can you walk on it?

No generally speaking. Typically its very painful and some can walk on it but not very well and people eventually succumb to the pain. And you should not it needs to be rested and you will need to were a walker boot/moon boot for 6 weeks while it heals.

What does it present like?

It presents very swollen within a very short period of time (typically 24hours). There is also a lot of bruising especially under the foot.

It should not be confused with a severe ankle sprain they are very very different!

How do I know if I have a Lisfrancs injury?

If you cannot walk after an injury described above and have the swelling and bruising the best thing is to present for imagine of the area. And interestingly a plain X-ray weight-bearing (AP) gives a lot of information as to the degree of the injury. If an MRI is performed it can give more detailed soft tissue and ligamentous information also.

Can a Lisfrancs injury be managed conservatively without surgery?

Yes it can! But it is still recommended that a minimum of 6 weeks in a non-weight bearing in a boot with crutch assistance is necessary for the injury to begin to heal. But please consult with an experienced rehabilitation provider and surgeon on the best treatment for your injury.
