About this study
Official title: Weight-bearing Diagnostics in Acute Lisfranc Injury: A Prospective Study Comparing Computed Tomography Versus Conventional Radiography
A prospective, cohort study comparing weight-bearing computed tomography with weight-bearing radiography in patients with an acute Lisfranc injury.
Read the detailed description
Injury to the tarsometatarsal (TMT) joint complex in the midfoot is referred to as a Lisfranc injury. The broad spectrum of these injuries includes simple sprains to severe fracture-dislocations. Variable clinical presentations and radiographic findings make Lisfranc injuries notoriously difficult to detect, especially in the case of subtle ligament injuries. Nowadays, up to 30% of unstable Lisfranc injuries are overlooked or misdiagnosed. This can potentially lead to severe sequelae such as post-traumatic osteoarthritis and foot deformities.
For obvious injuries involving diastasis, subluxation, or dislocation, the diagnosis is relatively easy to establish using any imaging modality. However, for subtle injuries without gross bone separation, a dynamic imaging modality facilitating weight-bearing are to be preferred. Many consider weight-bearing conventional radiography as the current gold standard in acute Lisfranc injury diagnostics. However, conventional radiography is a 2D technique that can neither display nor measure the true dimensions of a detailed 3D object, such as the tarsal bones in the foot. Computed tomography (CT) provides greater accuracy in visualizing bone microarchitecture. In combination with weight-bearing, it can be ideal for detecting minor fractures and occult instability caused by load/stress.
To this day, there are no prospective studies comparing weight-bearing CT and weight-bearing radiography for acute Lisfranc injuries. In the current study, participants will be assigned to non-operative or operative treatment based on Lisfranc joint stability evaluation by the initial weight-bearing CT.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Conservative treatmentProcedure or surgery
Patients with negativ weight-bearing CT will be treated conservative
Minimally invasive stabilizationProcedure or surgery
Patients with positive weight-bearing CT will be operated by minimally invasive stabilization (eg, isolated homerun screw)
| Study group | Role | What they receive |
|---|---|---|
| Cohort 1 - Conservative | Active comparator | Negative weight-bearing CT (≤ 2mm between C1-M2, as opposed to the uninjured side) will be considered stable and treated conservatively with a prefabricated walker with weight-bearing as tolerated for six weeks. These patients will undergo bilateral radiographs after six weeks and combined CT and radiographs after twelve weeks to monitor the degree of stability Receives: Procedure: Conservative treatment |
| Cohort 2 - Surgical | Active comparator | Positive weight-bearing CT (> 2mm between C1-M2, as opposed to the uninjured side) will be operated by minimally invasive stabilization (eg, isolated homerun screw) Receives: Procedure: Minimally invasive stabilization |

- Model description
- Acute Lisfranc injuries are investigated with weight-bearing diagnostics to determine the degree of TMT stability. Patients are examined using both CT and conventional radiography during full weight and non-weight-bearing sequences. 3 foot- and ankle surgeons will examine the scans independently, starting with the conventional radiographs. Distance between the medial cuneiform and second metatarsal bone (C1-M2) is measured. For the CT images, measuring method previously described by Y. Sripanich et al. (DOI: 10.1007/s00402-020-03477-5) will be used. CT findings will determine the treatment outcome. If the C1-M2 diastasis is \>2mm, as opposed to the uninjured side, the injury will be determined unstable and surgical fixation will be recommended (Cohort 2). All other patients (≤ 2mm) are considered stable and treated conservatively (Cohort 1).
