Flex digits

18
Q

The calcaneal bursa lies where

A

19
Q

What acts as flexors of the stifle

A

20
Q

T/F DDF contributes to common calcaneal tendon

21
Q

Soleus attachment in cats is similar to what muscle

A

Gastrocnemius

22
Q

What are some common causes of rupturing the common calcanean tendon

A

Trauma
Fracture of the calcaneus
Degenerative disease

23
Q

What are some major signs rupturing the common calcanean tendon

A

Non-weight bearing lameness

24
Q

Prognosis of rupturing of the common calcanean tendon

A

Good if apposition of tendons on calcaneus can be achieved

25
How to repair rupture of common calcanean tendon
Surgical repair and support with hock braces work well for management of a ruptured common calcaneal tendon in dogs
26
Muscles that extend the digits
Long digital extensor Lateral digital extensor
27
Muscles that flex the digits
SDF DDF
28
