Case: Our 26-year-old patient is a professional ballet dancer who suffered a classic Lisfranc joint injury while performing a dancing maneuver with his foot in full plantar flexion. Initial workup with radiographs revealed borderline Lisfranc interval widening without definitive joint instability. Further evaluation with an innovative dynamic stress magnetic resonance imaging (MRI) revealed mild interosseous Lisfranc ligament laxity and sprain, which allowed the orthopaedic surgeon to pursue conservative management, rather than surgery. After physical therapy, our patient reports a successful return to dancing.

Conclusions: Dynamic stress MRI may become a useful technique in evaluating equivocal cases of midfoot injury through the use of new imaging-based criteria.
