The second TMT joint is the articulation of the base of the second metatarsal with a mortise formed by the middle cuneiform and the sides of the medial and lateral cuneiforms (Figs. 16-3 and 16-18). It is stronger and its motion more restricted than the other TMT joints. The third TMT joint shares its capsule with the second TMT joint, whereas the fourth and fifth TMT joints share a capsule with their articulation with the cuboid. There are small plane articulations between the bases of the metatarsals to permit motion of one metatarsal on the next. Slight gliding and rotation are possible at all of these joints. Although there is little movement between the individual tarsals and metatarsals, their collective movement can enhance either the foot’s stability or flexibility. Dorsal and plantar ligaments join the bones (Figs. 16-14, 16-16, and 16-20). The plantar ligaments of the cuneocuboid and intercuneiform joints are strengthened by slips from the tendons of the tibialis posterior (Fig. 16-20).
