ankle

Question 1

Draw the surface markings of the ankle (Talocrural) joint

Answer 1

A horizontal line draws across the marking surface of ankle 2cm above the tip of the med. malleolus and 3cm above the tip of the lat. malleolus.
Continue down lat. side of med. malleolus and the med. side of lat. malleolus to the malleolar tips to complete the joint line.

Question 2

Peroneal Tubercle

Answer 2

Bony point inferior and slightly anterior to the tip of the lateral malleolus (Calcaneus)

Question 3

Tuberosity of the Navicular

Answer 3

Anterior to medial malleolus

Question 4

Sustentaculum Tali and the spring ligament

Answer 4

(Calcaneonavicular) - Below talus on medial side (calcaneus), Ligament from Sustentactulum Tali to Navicular

Question 5

First metatarsal & medial cuneiform

Answer 5

Medial Cuneiform is anterior to the Navicular. Base of first metatarsal is anterior to the Medial Cuneiform.

Question 6

Cuboid bone

Answer 6

Posterior to the base of the fifth metatarsal

Palpate and mark the base of fifth metatarsal bone, on lat. side - Move anteriorly from the Calcaneus, through a hollow (on lateral border of foot)

Question 7

Head of the Talus

Answer 7

Below medial malleolus when foot is everted. Anterior to lateral malleolus when foot inverted

Draw in the mid tarsal (transverse tarsal) joint - The mid tarsal joint can be marked across the foot from just proximal to the navicular tuberosity medially, to 1cm proximal to the tip of the tubercle of the fifth metatarsal laterally.

The line is concave proximally in its medial part and slightly convex proximally in its lateral part.

Question 8

Heads of the metatarsals on the plantar surface

Answer 8

Easier with toes dorsiflexed

Question 9

Dorsal Pedal Artery

Answer 9

between the first and second metatarsals (establish pulse compare with femoral pulse)

Question 10

Posterior Tibial artery

Answer 10

2cm posterior and 2cm inferior to the medial malleolus
