Tarsal Bones Talus (Talus): forms the ankle joint; features include trochlea, medial and lateral malleolar facets, and superior facet Trochlea of talus (Trochlea tali): saddle-shaped top surface that articulates with tibia and fibula Lateral process (Processus lateralis tali): attachment for lateral talocalcaneal ligament Posterior calcaneal articular facet (Facies articularis calcanea posterior): articulates with calcaneus Posterior process (Processus posterior tali): contains lateral and medial tubercles Groove for flexor hallucis longus (Sulcus tendinis musculi flexoris hallucis longi): transmits flexor hallucis longus tendon Sulcus tali (Sulcus tali): groove between articulating facets; forms sinus tarsi with calcaneal sulcus Middle calcaneal articular facet (Facies articularis calcanea media): articulates with calcaneus Anterior calcaneal articular facet (Facies articularis calcanea anterior): anterior articulation with calcaneus Navicular articular surface (Facies articularis navicularis): forms talonavicular joint Calcaneus (Calcaneus): heel bone; largest tarsal bone Calcaneal tuberosity (Tuber calcanei): insertion for Achilles tendon and plantar aponeurosis Medial and lateral processes (Processus medialis et lateralis tuberis calcanei): muscle origins including abductor digiti minimi, abductor hallucis Sustentaculum tali (Sustentaculum tali): supports talus head; attachment for ligaments Groove for flexor hallucis longus (Sulcus tendinis musculi flexoris hallucis longi): passes under sustentaculum Calcaneal tubercle (Tuberculum calcanei): supports long plantar ligament Fibular trochlea (Trochlea fibularis): guides fibularis tendons Anterior, middle, and posterior talar articular surfaces (Facies articulares talares): articulate with talus Cuboid articular surface (Facies articularis cuboidea): anterior surface for cuboid Calcaneal sulcus (Sulcus calcanei): forms sinus tarsi with sulcus tali Navicular (Os naviculare): located between talus and cuneiforms Tuberosity of navicular (Tuberositas ossis navicularis): insertion for tibialis posterior Cuboid (Os cuboideum): lateral bone between calcaneus and metatarsals Tuberosity of cuboid (Tuberositas ossis cuboidei): attachment for ligaments Groove for fibularis longus (Sulcus musculi fibularis longi): guides fibularis longus tendon Calcaneal process (Processus calcaneus ossis cuboidei): supports cuboid-calcaneus articulation Medial cuneiform (Os cuneiforme mediale): articulates with 1st metatarsal Intermediate cuneiform (Os cuneiforme intermedium): articulates with 2nd metatarsal Lateral cuneiform (Os cuneiforme laterale): articulates with 3rd metatarsal Metatarsals Metatarsals I–V (Ossa metatarsalia I–V): numbered medial to lateral; each has base, shaft, and head Tuberosity of 1st metatarsal (Tuberositas ossis metatarsalis primi): insertion for fibularis longus Tuberosity of 5th metatarsal (Tuberositas ossis metatarsalis quinti): insertion for fibularis brevis Phalanges Proximal phalanges (Phalanges proximales): 5 in total; base, shaft, and head Middle phalanges (Phalanges mediae): 4 total; absent in big toe Distal phalanges (Phalanges distales): 5 total; each ends with a tuberosity Tuberosity of distal phalanx (Tuberositas phalangis distalis): attachment site for soft tissue Mnemonic “Tiger Cubs Need MILC”: Talus, Calcaneus, Navicular, Medial, Intermediate, Lateral cuneiforms, Cuboid Sources: Kozlowski, T.
