Ankle & Foot Flashcards
Ankle Anatomy
Distal Tibiofibular Joint
Proximal Tibiofibular Joint
Talocrural Joint
Foot Anatomy
Hindfoot (rearfoot)
-Subtalar joint
Midfoot
- Transverse Tarsal (Midtarsal) Joints: Talonavicular & Calcaneocuboid
- Distal Intertarsal Joints: Cuneonavicular, Cuboidenavicular, Intercuneiform, Cuneocuboid
Forefoot
- Tarsometatarsal
- Intermetatarsal
- Metatarsophalangeal
- Interphalangeal
Distal Tibiofibular Joint
- Fibrous/syndesmosis type of joint
- Movement is minimal
- Spreads apart going into DF b/c Talus is wider anteriorly
- Ligaments: Anterior TibFib & Posterior TibFib Ligament
Distal Tibiofibular Joint Resting Position

Distal Tibiofibular Joint Capsular Pattern
Pain when joint is stressed
Talocrural Joint
- Modififed hinge, synovial joint
- This is the main ankle joint
- b/w Talus, Lateral & Medial Malleoli
-Movement = PF & DF
Talocrural Joint Resting Position
10deg PF & midway b/w inversion/eversion
Talocrural Joint Closed Pack Position
Max DF
Talocrural Joint Capsular Pattern
PF > DF
Subtalar Joint
3 articular facets
- Posterior: concave Talus, convex Calcaneus
- 2 Anterior: convex Talus, concave Calcaneus
-Movement = Inversion/eversion = responsible for alignment of Tranverse Tarsal Joint (locking/unlocking of midfoot)
- Pronated hindfoot = parallel axis = increased movement
- Supinated hindfoot = NOT parallel axis = decreased movement
Subtalar Joint Resting Position
Midway b/w extreme ROM
Subtalar Joint Closed Pack Position
Supination
Subtalar Joint Capsular Pattern
Varus > Valgus
Midtarsal Joints
Talonavicular & Calcaneocuboid
- minimal movement alone
- significant movement together (ADD & ABD)
