Sd Test 5 - Lower Limb 4

Front 1

Talus

Back 1

FHL tendon goes through groove btw posterior tubercles; blood vessels enter around neck.

Front 2

Talus fracture

Back 2

common injury from forced dorsiflexion (MVA). Fracture of neck can lead to AVN, death of talus.

Front 3

Sustentaculum Tali

Back 3

supports head of talus; tendon of FHL passes beneath

Front 4

Calcaneal Fracture

Back 4

often hurt due to high axial load on rear foot (jumping, falling). Must rule out associated fracture of lower spine. Injury involving STJ has poor prognosis, often leads to severe arthritis.

Front 5

Metatarsal Fractures

Back 5

Kicking, dropping something on foot. 5th commonly fractured, where Fibularis Brevis tendon inserts.

Front 6

Plantar Aponeurosis

Back 6

protects neurovascular structures of foot, supports longitudinal arch, helps compartmentalize foot.

Front 7

Posterior Tibial Nerve

Back 7

splits into Medial and Lateral Plantar Nerves

Front 8

Medial Plantar Nerve innervates

Back 8

4 intrinsic foot muscles: FDB, Abductor Hallucis, FHB, 1st medial lumbrical

Front 9

Lateral Plantar Nerve innervates

Back 9

all other intrinsic muscles of foot

Front 10

Medial Plantar Nerve sensory

Back 10

medial dorsum of foot and medial 3.5 toes

Front 11

Lateral Plantar Nerve sensory

Back 11

lateral dorsum of foot and 1.5 toes

Front 12

Tarsal Tunnel

Back 12

passage beneath flexor retinaculum for: Tendons of Tibialis Posterior and Flexor Digitorum Longus; Posterior Tibial Artery and Nerve; Tendon of Flexor Hallucis Longus.

Front 13

Posterior Tibial Artery

Back 13

divides into Medial Plantar Artery and Lateral Plantar Artery

Front 14

Medial Plantar Artery

Back 14

has superficial and deep branches; supplies mainly muscles of big toe

Front 15

Deep Plantar Arch

Back 15

formed from lateral plantar and deep plantar artery (from dorsalis pedis), uniting blood supply of plantar and dorsal surfaces. gives off metatarsal arteries and digital branches.

Front 16

Diabetic Foot Ulcers

Back 16

neuropathy causes loss of cutaneous sensation to plantar foot.

Front 17

Subtalar Joint

Back 17

plane synovial joint btw talus/calcaneous. Permits inversion and eversion during gait cycle. stabilized by interosseous talocalcaneal ligament.

Front 18

Transverse Tarsal Joint

Back 18

made up of 2 joints: calcaneocuboid and Talonavicular. same function as STJ.

Front 19

Calcaneonavicular Ligament

Back 19

spring ligament from sustenaculum tail to navicular. Has lots of elastic. Helps support longitudinal arch.
