Flashcards in Equine Appendicular Skeleton Deck (34):
1

how many views are required to assess equine joints

4

lateromedial, dorsoplamar/plamtar, DMPLO, DLPMO

2

when obtaining images of the distal extremities what should be done increase technical quality

remove shoes

lateral sulci are cleaned and packed with moldable material

3

where is the marker placed in equine radiographs

same conventions as small animal

dorsal on latero-medial view

lateral on all other viewa 

4

what is the most commonly affected joint in horses with hindlimb lameness

tarsus

5

lateral trochlear ridge can be identified by __________

large notch at its distal aspect

6

T/F appearance of medial traochlear ridge is variable

True

7

osteochondrosis is most common in which joint

tarsocrural

often bilateral

8

cranial aspect of the intermediate ridge of the distal tibia (DIRT) is best seen on which view

DMPLO

9

10

T/F fragments of OCD may settle to the bottom of the joint

True

11

what is the most common cause of lameness associated with the tarsus

bone spavin

12

which joints are most frequently involved in bone spavin

distal intertarsal and tarsometatarsal

13

what is the most common finding with bone spavin

periarticular osteophyte formation

14

signs associated with advanced done spavin

suchondrial bone lysis and narrowing of joint space

may progress to sclerosis and eventual ankylosis (fusion of joint)

15

T/F degress of changes correlates to clinical signs in bone spavin

false

16

how many ossifications centers does the distal radius have

2

distal radial and ulnar epiphysis

17

chip fracture deteched or not detected

not detetched

normal anatomy 

18

what disease is present here

osteoarthrosis

19

disease of the metacarpal/tarsal bones

splints - periosteal reaction and possible stenosis of metacarpal/tarsal bones

bucked shins or metacarpal periostitis

sequestrum

trauma 

20

the distal phalanx does not have a __________

medullary cavity

21

what is a smooth rounded concavity prominent in the distal phalanx of the hindlimb

crena marginis solearis

22

name the condition pictured 

club foot - palmar tendon deformity/contracture

23

signs associated with spetic coffin joint

increased synovial mass

marked lysis of adjacent bone

amorphous periosteal reaction

soft tissue swelling 

subluxation 

24

name the condition

moderate laminitis and rotation

25

what abnormalities are present

severe laminitis, penetration of sole and rotation

26

what are the four surfaces of the navicular bone

proximal, distal, articular, and flexor

27

the flexor surface of the navicular bone has a prominant __________

central ridge - central eminence

28

how many synovial invaginations are present on a normal navicular bone

no more than 7

relatively triangular in shape

29

T/F there is no universal agreement as to the clinical importance of all radiographic signs of navicular disease

True

30

do you see what I see

there are several areas of radiolucency - cysts

synovial invaginations evident 

31

subluxation deteched or not detected

deteched 

32

what abnormality is indicated by the arrow (outlined in yellow)

enthesophyte - abnormal bony projections at the attachment of a tendon or ligament

navicular remodeling 

33

whats wrong with this horse

severe remodeling, irregular distal surface, multiple irregular synovial invaginations, mineralization of ligaments (enthesophyte)

34

navicular fracture deteched or not deteched 

detected
