Intertarsal joints :
- Are the connections between the tarsal bones in the human foot.
- The intertarsal joints :
- 1. Subtalar joint (talocalcaneal )
- 2. Talocalcaneonavicular joint
- 3. Calcaneocuboid joint — together called Transverse tarsal joint
- 4. Cuneonavicular joint.
- 5. Cubideonavicular joint.
- 6. Intercuneiform joints.
Subtalar joint :
- Type : Plane synovial joint, allowing eversion & inversion.
- Articular Surfaces :
- Between concave inferior surface of talus and convex superior surface of calcaneus.
- Capsule
- Ligaments :
- Medial talocalcaneal ligament
- Lateral talocalcaneal ligament
- Posterior talocalcaneal ligament
- Interosseous talocalcaneal ligament
- Cervical ligaments
Transverse tarsal joint :
Is a compound joint formed by 2 separates joints
- 1. Talonavicular part of the talocalcanionovicular joint.
- 2. Calcaneocuboid joint
- Type : saddle joint.
- Ligaments :
- Talonavicular joint:
- 1. Planter calcaneonavicular
- 2. Calcaneonavicular
- 3. talonavicular
- 4. medial collateral
- Calcaneocuboid joint:
- 1. planter calcaneocuboid.
- 2. long planter
- 3. Calcaneocuboid
- 4. Dorsal calcaneocuboid
- Blood supply
- Lateral tarsal artery nourishes the joint.
member, this intricate joint allows your foot
- Innervation :
- Talonavicular joint:
- Deep fibular nerve
- Medial plantar nerve
- Calcaneocuboid joint:
- Deep fibular nerve
- Sural nerve
- Lateral plantar nerve
- Movements :
Supination. - Pronation.
