Flashcards in Superficial posterior leg Deck (20):
1

Location of subcutaneous calcaneal bursa

Between skin and calcaneal tendon

2

Location of deep bursa of calcaneal tendon

Between calcaneus and calcaneal tendon

3

What bursae are associated with calcaneal tendon

Subcutaneous calcaneal bursa
Deep bursa of calcaneal tendon

4

What are the muscles of the superficial posterior leg

Gastrocnemius
Plantaris
Soleus

5

Origins of gastrocnemius

Lateral head originates from lateral femoral condyle
Medial head originates from the medial femoral condyle

6

Insertion of gastrocnemius

Combines with soleus to form calcaneal tendon which inserts onto calcaneus

7

Action of gastrocnemius

Plantarflexion of foot
Flexion at knee

8

Innervation of superficial posterior leg

Tibial nerve

9

What percentage of the population don't have plantaris

10%

10

Origin of plantaris

Lateral Supracondylar line of femur

11

Insertion of plantaris

Blends with calcaneal tendon which inserts on calcaneus

12

Course of plantaris tendon

Descends between gastrocnemius and soleus

13

Action of plantaris

Plantarflexion of foot
Flexes at knee

14

Origin of soleus

Soleal line of tibia and proximal fibula area

15

Insertion of soleus

Joins calcaneal tendon which inserts on calcaneus

16

Action of soleus

Plantarflexion of foot

17

What is rupture of calcaneal tendon

Partial or complete tear of calcaneal tendon

18

Who is more likely to obtain a ruptured calcaneal tendon

People with history of calcaneal tendinitis (chronic inflammation of tendon)

19

Usual cause of ruptured calcaneal tendon

Forceful plantarflexion of foot

20

Consequence of ruptured calcaneal tendon

Unable to plantarflex foot against resistance
Affected foot is permanently dorsiflexed
Soleus and gastrocnemius can contract to form lump in calf region
