Detailed Plantar Anatomy of the Male Lisfranc Ligaments

Description

Plantar anatomy of the midfoot is rendered with the medial cuneiform positioned medial and proximal to the base of the second metatarsal, where the Lisfranc ligament complex spans the tarsometatarsal interval. The first through fifth metatarsals extend distally toward the phalanges, while the tarsus includes the cuneiforms and cuboid anterior to the calcaneus and talus. Ligament bundles are color-coded to distinguish the principal stabilizers from adjacent capsular and intermetatarsal fibers, clarifying how the second metatarsal base sits recessed between the medial and lateral cuneiforms. Orientation stays anatomic, with medial structures on the hallux side and lateral structures on the fifth ray. Disruption of the plantar Lisfranc ligament between the medial cuneiform and second metatarsal is the lesion that drives instability in Lisfranc injuries, often after a low-energy twist or a high-energy crush, and it is frequently underestimated when dorsal findings are subtle. This plantar emphasis matters because the plantar ligaments resist diastasis and sagittal plane collapse at the tarsometatarsal joints, the same mechanics that produce widening between the first and second rays and plantar ecchymosis in acute injury. A surgical or radiologic reader can map these fibers directly to stress radiographs, weightbearing CT, and the fixation corridors used in primary arthrodesis or transarticular screw constructs. Small footprint. Big consequences. Use this artwork for teaching the tarsometatarsal joints in gross anatomy, lower-limb MSK blocks, and podiatry or orthopaedic foot and ankle modules where students need a clean spatial explanation of the Lisfranc complex. It also suits journal figures, patient education sheets on Lisfranc sprain versus fracture-dislocation, and operative reports discussing ligamentous instability patterns across the midfoot.
