“It was one of these subtle cases and I needed to get an accurate 3D model and distance map to see how to approach this patients’ treatment." - François Lintz, MD.
The accurate 3D models, revealed a very subtle but asymmetrical TMT1 arthritis on the left foot, where the metatarsal had slipped on the cuneiform (Figure 1).
By comparing the joint spacing between the left and right TMT1 you can see the subtle narrowing of the left TMT1 joint indicative of arthritis (Figure 2).

Distance mapping of the Lisfranc region (Figure 3) showed subluxation and approximation in the dorsal aspect of the joint explaining the patient's pain.
These insights allowed Dr Lintz to choose the most appropriate treatment, firstly a pair of supporting insoles, then a TMT1 fusion.
“This case clearly illustrates why Disior’s software is a game changer for common foot problems."
