Tarsal Joints (intertarsal)
|
Foot - Intertarsal joints
Talocalcaneal (subtalar) joint
- Is a plane synovial joint (part of the talocalcaneonavicular joint), and is formed between the talus and calcaneus bones.
- Allows inversion and eversion of the foot.
Talocalcaneonavicular joint
- Is a ball-and-socket joint (part of the transverse tarsal joint), and is formed between the head of the talus (ball) and the calcaneus and navicular bones (socket).
- Is supported by the spring (plantar calcaneonavicular) ligament.
Calcaneocuboid joint
- Is part of the transverse tarsal joint and resembles a saddle joint between the calcaneus and the cuboid bones.
- Is supported by the short plantar (plantar calcaneocuboid) and long plantar ligaments and by the tendon of the peroneus longus muscle.
Transverse tarsal (midtarsal) joint
- Is a collective term for the talonavicular part of the talocalcaneonavicular joint and the calcaneocuboid joint. The two joints are separated anatomically but act together functionally.
- Is important in inversion and eversion of the foot.

|
Tarsometatarsal joints
|
- Are plane synovial joints that strengthen the transverse arch.
- Are united by articular capsules and are reinforced by the plantar, dorsal, and interosseous ligaments.
|
Metatarsophalangeal joints
|
- Are ellipsoid (condyloid) synovial joints that are joined by articular capsules and are reinforced by the plantar and collateral ligaments.
|
Interphalangeal joints
|
- Are hinge-type (ginglymus) synovial joints that are enclosed by articular capsules and are reinforced by the plantar and collateral ligaments.
