1

Superior/Proximal Check Ligament supports the ______

and attaches to the back of the radius

SDF

2

Inferior/Distal Check Ligament supports the ______ and

attaches to the back of the cannon bone (MC3)

DDF

3

________ surrounds fascicles and wraps around the entire tendon

Endotenon

4

________ surrounds the endotenon and tendon

Epitenon

5

___________ surrounds tendons that are NOT in a sheath

and OUTSIDE a synovial cavity

Paratenon

6

What are the regions of the tendon stress-strain curve

from start to failure?

Toe region - Elastic region - Yield point - Plastic region - Failure

 

TEY PF

7

Tendons can extend _______% before rupture

12 - 20%

8

Scar tissue, formed with Type 3 collagen results in a

less ELASTIC tendon with an increased ______ region

plastic

9

Tendons in a tendon sheath are _______ efficient at healing

than tendons outside a sheath

LESS

10

What are the 3 causes of tendonitis?

Overuse

Infection

Traumatic injury

11

These 2 tendons/ligaments are the most prone to injury due to

having the most load during heel strike

SDFT and SL

12

The most common tendon/ligament to tear

WITHIN a synovial cavity is the ________ in the FORElimb

and the ________ in the HINDlimb

DDFT- forelimb

Manica Flexoria- hindlimb

13

Core lesions are seen most commonly in this tendon

SDFT

14

Tendonitis within a tendon sheath is known as 

tenosynovitis and can lead to this condition

Annular ligament constriction

15

On physical exam, you see bowing of the palmar contour of

the distal limb in a horse. What is causing this?

Tendonitis!

16

This is the best tool for diagnosing tendonitis

ULTRASOUND

17

What type of probe is used for diagnosing tendonitis with

and ultrasound?

7.5 - 12 MHz LINEAR transducer 

18

How does the view of the tendons change at the level

of the fetlock on Ultrasound?

The DDFT becomes BILOBED at the pastern (P1-P2 area)

19

When taking measurements when ultrasounding a limb

for tendonitis, you should measure the distance between 

the transducer and the ___________ 

ACCESSORY CARPAL BONE

20

When ultrasounding a limb for tendonitis,

______ injuries will be HYPOechoic, where as

________ injuries will be HYPER or HETEROechoic

Acute- HYPO

Chronic- HYPER/HETERO

21

A reduced striated pattern indicates _______ tendon injury

where as an

irregular striated pattern indicates ______ tendon injury

REDUCED striated = ACUTE

 

IRREGULAR striated = CHRONIC

22

T/F:

You suspect a tendon injury where the DDFT inserts onto P3.

The best diagnostic tool to use here is Ultrasound

FALSE!

 

This is blocked by the hoof capsule, so will have to use MRI

23

What type of NSAID is given to horses with tendonitis or tendon injuries?

Phenylbutazone

24

T/F:

Blood and bone marrow concentrates can be therapeutic in

equine tendonitis, desmitis, and osteoarthritis

TRUE

25

Adipose derived mesenchymal stem cells differentiate into

musculoskeletal tissue but are INFERIOR to 

__________

Bone Marrow

26

What are the two types of desmotomy procedures

used in equine tendon repair?

Superior Check Desmotomy

and

Annular Ligament Desmotomy

27

Inflammation of the ligament is known as

DESMITIS
