A

Metacarpal bone

25
Q

This is a transverse section from the level of the distal metacarpus.
What tendon can’t we see here and why?

A

Can’t see the ALDDFT at this levels because it has by now merged with the DDFT

26
Q

This is a transverse ultrasound image from the level of the distal metacarpus. What can you see that is abnormal?

A
  • The SDFT (A) is slightly enlarged on one side and should normally be more symmetrical
  • This image was taken from a racehorse with a SDFT injury

Q

This is a transverse section from the level of pastern region.
What is A?

A

SDFT

Note the ‘spaniel ear’ appearance at this level.

44
Q

This is a transverse section from the level of pastern region.
What is B?

A

DDFT

It has a bi-lobed appearance at this level.

45

51
Q

This is a longitudinal ultrasound image. What abnormality can you see here?

A
  • The SDFT is slightly enlarged and reduced in echogenicity (darker than normal)
  • This is from a racehorse with a SDFT injury
52
Q

This is a longitudinal ultrasound image of the distal limb.
What is A?

53
Q

This is a longitudinal ultrasound image of the distal limb.
What is B?

54
Q

This is a longitudinal ultrasound image of the distal limb.
What is C?

55
Q

This is a longitudinal ultrasound image of the distal limb.
What is D?

A

Interosseous / suspensory ligament

Note the “messy” appearance; in other species this is a muscle with fat embedded within. This explains why it doesn’t appear very homogenous on ultrasound.
