Caption: Figure 1: An X-ray of the left foot showed a commuted fracture of the cuboid bone with mildly displaced fragments, as well as moderate soft tissue edema (red arrows).
The highest area of foot contact was for the metatarsal heads (20.1 [+ or -] 1.2%), the toes (18.3[+ or -]2.4%), and the cuboid bone (17.8[+ or -]1.7%) in control group.
Significant differences were also observed for the magnitude of plantar pressure under the first metatarsal heads (mask 3), cuboid bone (mask 4), and navicular bone (mask 5).
As the cuboid bone is part of the fifth ray joining the forefoot to the calcaneus, the limited movement of the calcaneo-cuboid joint or joints between the fourth and fifth metatarsals and the cuboid may lead to decreased ability to rise onto demi-pointe or full pointe.
