Tendonitis

Question 1

Where does the superficial digital flexor insert

Answer 1

Dividies

Question 2

What is found inside an endotenon?

Answer 2

intrinsic blood supply, nerves, growth factors, provides elasticity

Question 3

Describe the epitendon

Answer 3

Structure contiguous with endotenon, surrounds tendon

Question 4

Describe the paratenon

Answer 4

Structure that surrounds tendons not in a sheath, reduces frictional forces, supplies blood vessels, repair elements

Question 5

What is the purpose of the crimp pattern?

Answer 5

Provides about 3% of lengthening of tendon –> crimp is lost once load is applied

– Eliminated with age

Question 6

How far can a tendon extend before it ruptures?

Answer 6

12-20%

Question 7

What is the tendon extension of the toe?

Answer 7

1-3%

Question 8

What is the tendon extension at the trot?

Answer 8

8-9%

Question 9

What type of collagen is normally found in joints? What is it replaced with after repair?

Answer 9

Normally collagen type I –> after injury becomes type III

** returns to type I collagen over time = better

Question 10

What is tendonitis?

Answer 10

Inflammation of a tendon, most coommonly from overuse, infection, or traumatic injury

** superficial digital flexor tendonitis is the most common form

Question 11

What structures are most prone to injury (tendonitis/ desmitis)?

Answer 11

Superficial digital flexor tendon and suspensory ligament –> take most load during heel strike

Question 12

What synovial structure most commonly is prone to damage?

Answer 12

Deep digital flexor tendon

Question 13

How long should you wait to perform an US to exam possible tendonitis?

Answer 13

1 week –> allows for inflammation to decrease

Question 14

What are some treatments for tendonitis?

Answer 14

• Cold therapy

- NSAIDs
