TPT footprints. Green ovals mark the possible TPT insertion sites. The navicular bone is the main insertion site but up to 8 distinct bony insertions of the TPT in a single foot have been detected. The second most common footprint was the lateral cuneiform (93%). At the cuboid the location of insertion was highly variable and at the calcaneus the anterior aspect of the sustentaculum tali and the distal medial distal aspect could be identified as PTT footprint location. All metatarsal bases can be involved in TPT anchoring
