Computed Tomography with Stress Maneuvers for Evaluation of Distal Tibiofibular Syndesmosis Instability (CTMETS)
Comparative Computed Tomography with Stress Maneuvers for Evaluation of Distal Tibiofibular Syndesmosis Instability in Adults After Acute Ankle Sprain: a Test Accuracy Study
Hospital Israelita Albert Einstein
133 participants
Sep 1, 2018
OBSERVATIONAL
Conditions
Summary
The main aim of this study was to investigate which strategy can diagnose more accurately syndesmotic instability among an existing index test (ankle CT in neutral position) and two new add-on index tests (ankle CT in a stress position with extended-knees and ankle CT in a stress position with flexed-knees). This study hypothesized that the two add-on ankle CT with stress maneuvers (CTSM) have a more accurate capability of diagnosing syndesmotic instability than ankle CT in a neutral position (CTNP) alone. The secondary objective is to investigate the participants' disability outcomes by applying the Foot and Ankle Ability Measure questionnaire.
Eligibility
Inclusion Criteria4

Exclusion Criteria5
- Bilateral ankle sprain;
- Previous ankle surgery;
- Ankle fractures and dislocations (except avulsion fractures in ligamentous insertions or fracture of the posterior malleolus related to syndesmotic injury);
- Congenital or acquired ankle deformities;
- Infection, inflammatory, or neuropathic ankle arthropathies.
