Objective: The bony articulation characteristics of the first, second and third tarsometatarsal joint complex (Medial Lisfranc Joint Complex) play a critical role in its stability and are frequently associated with the injuries of these joint complex. This study aimed to investigate whether morphological differences in the medial tarsometatarsal joint complex bones increase the risk of tarsometatarsal joint injury by comparing patients with injuries to a healthy control group using three-dimensional (3D) modelling.
Methods: In this retrospective multicenter study, we analyzed 48 CT scans—23 from patients with tarsometatarsal joint injuries and 25 from healthy controls without a history of midfoot trauma. The first three metatarsals (M1-M3) and cuneiforms (C1-C3) were segmented to create 3D models. We measured bone lengths, articular surface areas, volumes, and step-off differences (e.g., M1-M2 depth, M2–C2 dorsal height) and compared these parameters between groups.
Results: No significant differences were observed in any bony morphological parameters between the injury and control groups (p > 0.05). The mean M1–M2 depth difference in the injury group was 8.2 ± 2.3 mm, similar to controls. Similarly, cuneiform volumes, articular surface areas, and step-off alignments (e.g., M2–C2 dorsal height) did not differ significantly.
Conclusion: Our findings suggest that bony morphology alone does not predispose individuals to tarsometatarsal joint injuries. Future studies should explore combined assessments of bony and ligamentous anatomy to better understand injury mechanisms.
