Transverse MR images of the right tarsal joint: a SE T1-weighted and (b) GE STIR T2-weighted. Line depicts the section at the level of the proximal tarsal bones (IV), distal tarsal bones (V) and metatarsal bones (VI). Cal = calcaneus, Tc = central tarsal bone, T1 = 1st tarsal bone, T2 = 2nd tarsal bone, T3 = 3rd tarsal bone, T4 = 4th tarsal bone, MI = 1st metatarsal bone; MII = 2nd metatarsal bone, MIII = 3rd metatarsal bone, MIV = 4th metatarsal bone, MV = 5th metatarsal bone. 1 = dorsal extensor retinaculum, 2 = interosseous intertarsal ligament between the calcaneus and central tarsal bone, 3 = long plantar ligament, 4 = calcaneoquartal ligament, 5 = interosseous intertarsal ligament between the T3 and T4, 6 = interosseous intertarsal ligament between the T2 and T3, 7 = interosseous intertarsal ligament between the T1 and T2, 8 = tarsometatarsal ligament, 9 = cranial tibial tendon; 10 = long digital extensor tendon, 11 = short digital extensor muscles, 12 = lateral digital extensor tendon, 13 = long fibular tendon, 14 = tarsal fibrocartilage, 15 = lateral digital flexor tendon, 16 = medial digital flexor tendon, 17 = superficial digital flexor tendon, and 18 = interosseous muscle
