About this study

Official title: Stability and Outcomes of Non-displaced Lisfranc Injuries - A Prospective Multicenter Cohort Study

In this multicenter cohort study, the stability of non-displaced Lisfranc injuries as well as their outcomes will be evaluated.

Read the detailed description

Injuries to the tarsometatarsal joints ("Lisfranc injuries") that are non-displaced on non-weightbearing radiographs and CT are common injuries. To refer these injuries to the right treatment, evaluating their stability is essential. For this purpose, both weightbearing radiographs and stress fluoroscopy have been proposed. However, there is no consensus concerning both the use and interpretation of weightbearing radiographs and no standardized technique and interpretation of stress fluoroscopy in non-displaced Lisfranc injuries.

In the current study, participants will be assigned to non-operative or operative treatment based on Lisfranc joint stability evaluation by weightbearing radiographs.

All Patients with negative weightbearing radiographs will be treated conservatively. In addition, their injured feet will be evaluated by manual stress fluoroscopy. Depending on the result of the stress fluoroscopy (positive/negative), the conservatively treated patients will be assigned to 2 cohorts, whose outcomes will be compared.

Patients with positive weightbearing radiographs will be treated operatively by minimally invasive stabilization of the midfoot (eg. isolated "homerun screw"). The operatively treated patients will be followed up as an independent cohort.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Manchester-Oxford Foot Questionnaire (MOxFQ)

    Foot-Ankle specific PROM (0-100 with 0 representing the best possible outcome)

    Measured: 5 years

Secondary outcomes (6)
  1. American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Midfoot score

    Widely used foot/ankle score (0-100 with 100 representing the best possible outcome)

    Measured: 5 years

  2. Self-reported foot and ankle score (SEFAS)

    Foot-Ankle specific PROM (0-48 with 48 representing the best possible outcome)

    Measured: 5 years

  3. Visual Analogue Scale (VAS) for pain

    Scores pain at rest and on activity (0-10 with 0 representing no pain)

    Measured: 5 years

  4. Short-Form (SF) 36

    Patient reported score measuring quality of life and health status

    Measured: 5 years

  5. Posttraumatic osteoarthritis

    The presence of osteoarthritis of the tarsometatarsal joints is graded based on the Brodén radiographs taken at 1 year, 2 year and 5 year follow-up using the Kellgren \& Lawrence classification system.

    Measured: 5 years

  6. Incidence of complications

    Yes/no for deep or superficial infection, nerve or tendon injury, deep venous thrombosis, hardware complaints and secondary surgery. Regards the patients that have undergone surgical treatment.

    Measured: 5 years

Model description
Participants are evaluated by weightbearing radiographs. Patients with no signs of dislocation on the weightbearing radiographs will undergo stress fluoroscopy. Patients with negative stress fluoroscopy are allocated to Cohort 1, patients with positive stress fluoroscopy are allocated to Cohort 2. The study design is a non-inferiority study, proving to show that the outcomes of Cohort 2 are non-inferior compared to Cohort 1. Patients with positive weightbearing radiographs (interval between medial cuneiform and base of second metatarsal increased by \> 2 mm compared to the contralateral side) will be operated with minimally invasive stabilization (eg. isolated "homerun screw") and followed up prospectively as a single cohort (Cohort 3).

Questions about this trial

What is this clinical trial studying?

A study testing Minimally invasive stabilization of Lisfranc injuries and Conservative treatment in people with Lisfranc Injury and Sprain of Foot, run by Ostfold Hospital Trust at 2 sites in Norway.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 1 May 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Norway. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Manchester-Oxford Foot Questionnaire (MOxFQ) (time frame: 5 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 May 2023; AzTrials last refreshed its copy on 7 Nov 2026.
