Session 34 - The Posterior Leg and Sole of the Foot Flashcards
A patient sustained a traumatic injury which severed his sciatic nerve in his gluteal
region. What functional deficits would you expect him to have?
Tibial - Posterior thigh, posterior leg, sole of foot inc skin
CPN - Anterior leg, lateral leg, skin over lat leg and dorsum of foot
What branches does the sciatic nerve give off?
tibial and common peroneal nerves
Which muscles attach to the Achilles tendon? If a patient ruptured the tendon,
what function deficit would result?
Gastrocnemius
Soleus
Plantaris.
Plantarflexion
Where is the great saphenous vein formed? Describe its course from its distal
origin to its proximal termination
Origin - Medially from dorsal venous network of the dorsum of the foot
Terminates - Femoral vein - just below inguinal ligament
Which muscles flex the toes?
Flexor digitorum longus and flexor digitorum brevis flex toes 2-5.
Flexor hallucis longus and flexor hallucis brevis flex the big toe.
How many muscle layers are in the sole of the foot?
4
What innervates extensor digitorum brevis?
Deep peroneal nerve
What are the key nerves of the sole of the foot? From which nerves do they arise? How to they enter the sole of the foot?
Medial and Lateral plantar nerves - terminal branches of the tibial nerve
All intrinsic muscles of the foot
BAR EDB
What are the key arteries of the sole of the foot?
From which arteries do they arise? How to they enter the sole of the foot?
The major arteries of the sole of the foot are the medial and lateral plantar arteries
Terminal branches of the posterior tibialartery.
The lateral plantar artery forms the deep plantar arch, which anastomoses with a branch of the dorsalis pedis artery
A patient presents with an aching, swollen, red and warm leg. What is the likely
diagnosis? Which muscles of the leg are key in preventing this condition?
Deep vein thrombosis
May lead to pulmonary embolism
Posterior leg muscles
