Metacarpus/ Metatarsus

Question 1

How many levels and zones are there in the metatarsus?

Answer 1

8 levels 4 zones (level 1 zone 1 is proximal between the tuber calcis and the TMTj)

Question 2

What occurs at level 4 (2B)

Answer 2

The SL branche have began to devide btu have not devided.

Question 3

What is the difference between level 5 (3A) and level 6 (3B)?

Answer 3

The SL branches are just further appart

Question 4

Whats occurs at level 7 (3C)?

Answer 4

Level of the PAL

Question 5

At zone 2a/b is the SDFT thicker laterally or meidally?

Answer 5

Medially

Question 6

How does the SDFT compare in echogenicity with the DDFT and ALDDFT?

Answer 6

Slightly less echogenic

Question 7

What tendon layer is missing within tendon sheaths?

Answer 7

Paratenon

Question 8

Why is the term tendonitis/ desmitis not the best to use?

Answer 8

As inflammation is not always a major pathophysiological component of the condition, tendinopathy/desmopathy is more appropriate.

Question 9

Where are SDFT lesions most common?

Answer 9

Mid metacarpal region

Question 10

What change in CSA of the SDFT is considered significant which comparing with the contralateral limb?

Answer 10

>20%

Question 11

What is causing the scattered hyperechoic foci within the SDFT?

Answer 11

With no alteration in longitudinal fibre pattern this is suggetive of age related degeneration which can be normal.

Question 12

How frequently should teondon inurys be re-examined?

Answer 12

q3months

Question 13

What change in CSA at re-examination is indicative of reinjury

Answer 13

increase byt 10%

Question 14

At what stage is doplier sign expected during tendon healing?

Answer 14

3-6months

Question 15

Interval between injury and return to training for racehorses is what?

Answer 15

9-18 months (but complete healing histologically takes 15-18months).

Question 16

What occurs with a bandage bow?

Answer 16

contusion and bleeding occur deeper, at the tendon interface. The effects of local trauma can vary from localized subcutaneous or peritendinous edema with no evidence of intratendi- nous damage through localized hypoechoic/anechoic lesions on the palmar surface of the tendon

Question 17

Paratenon typically measures?

Answer 17

1-2mm

Question 18

A curb is typically casued by what injury?

Answer 18

has long been associated with injury to the long plantar ligament of the tarsus (A; arrows). (B), (C) This is in fact extremely rare and curb is most often caused by subcutaneous and peritendinous thickening (yellow arrows) and/or injury to the SDFT.

Question 19

One of the most sensitive indicators of suspensory branch desmitis is?

Answer 19

periligamenous fibrosis

Question 20

Time for SL injuries to heal is usually shorter or longer tna SDFT?

Answer 20

Shorter (6-9m typically)
