Anatomy (Bones and Muscles) · MU Sofia

31. Cuneonavicular and intercuneiform joints. Metatarsophalangeal and interphalangeal joints.

Covers the subtalar joint between the talus and calcaneus, classed as a plane synovial joint permitting eversion and inversion, with its articular surfaces, capsule and talocalcaneal and cervical ligaments. Then explains the transverse tarsal joint as a compound saddle joint made of the talonavicular and calcaneocuboid joints, listing their ligaments, blood supply, innervation and movements of supination and pronation. Also includes an overview of the intertarsal joints and a list of the foot's joints, with pictures and a table of the medial and lateral longitudinal arches and the transverse arch.

Introduction

30 + 31

Intertarsal joints :

  • Are the connections between the tarsal bones in the human foot.
  • The intertarsal joints :
  1. 1. Subtalar joint (talocalcaneal )
  2. 2. Talocalcaneonavicular joint
  3. 3. Calcaneocuboid joint — together called Transverse tarsal joint
  4. 4. Cuneonavicular joint.
  5. 5. Cubideonavicular joint.
  6. 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. 1. Talonavicular part of the talocalcanionovicular joint.
  2. 2. Calcaneocuboid joint
  • Type : saddle joint.
  • Ligaments :
  • Talonavicular joint:
  1. 1. Planter calcaneonavicular
  2. 2. Calcaneonavicular
  3. 3. talonavicular
  4. 4. medial collateral
  • Calcaneocuboid joint:
  1. 1. planter calcaneocuboid.
  2. 2. long planter
  3. 3. Calcaneocuboid
  4. 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.
