25
What is the most common cause of lameness associated with the tarsus?
Bone spavin
26
Which joints are most frequently involved in bone spavin?
Distal intertasal and tarsometatarsal
27
What is the most common finding in bone spavin?
Periarticular osteophyte formation
28
What might advanced bone spavin have?
Subchondral bone lysis and narrowing of the joint space
29
What can bone spavin progress to?
Sclerosis and eventual ankylosis
30
T/F: The degree of changes in bone spavin does not often correlate well to clinical signs
TRUE
31
What does this indicate?
Degenerative joint disease
32
Disease?
Severe DJD
33
T/F: The distal radius forms from 2 ossification centers--the distal radial and ulnar epiphysis (closes at 9 mo)
TRUE
34
How many ossification centers can the accessory carpal bone have?
2--close between 5-7mo
35
What's wrong with this carpus?
NOTHING--the arrow is pointing to an area that hasn't fused yet
36
What is the arrow pointing to? What view is this?
Arrow is pointing to the 1st carpal bone DMPLO view
37
7 possible diseases of the carpus?
1. Trauma 2. Carpal fractures 1. Chip 2. Slab 3. Osteochondrosis 4. Physitis 5. Angular limb deformities 6. Septic arthritis 7. Osteoarthrosis
38
What is wrong with this carpus?
Radial carpal bone chip fracture
39
Diagnosis?
Osteoarthrosis (severe)
40
Possible diseases of the metacarpal/-tarsal bones?
* Splints--periosteal reaction and possible synostosis of metacarpal/tarsal bones * Bucked shins or metacarpal periostitis * Sequestrum * Trauma
41
What is used to examine the tendons when suspecting disease of the metacarpal/tarsal bones?
Ultrasound
42
Diagnosis?
Sequestrum
43
T/F: In the proximal phalanx there are many vascular channels that radiate from the solar margin centrally
FALSE--in the **distal** phalanx
44
Does the distal phalanx have a medullary cavity?
Nope
45
What is the crena marginis solearis?
A smooth rounded concavity of the distal phalanx solar margin (more prominent in hind limb)
46
What is wrong here?
NOTHING--**this is normal**
47
Possible diseases of the phalanges?
* Traumatic fractures * Tendon injury, deformity, or contracture * Infection * Osteomyelitis * Septic osteitis * DJD * Laminitis * Pedal osteitis * Side bone * Keratoma (rare)
48
Diagnosis?
Club foot--palmar tendon deformity/contracture
49
What are the characteristics of a septic coffin joint?
* Increased synovial mass * Marked lysis of adjacent bone * Amorphous periosteal reaction * Soft tissue swelling * Subluxation
50
Is anything wrong with this?
Moderate laminitis and rotation
51
Diagnosis?
Severe laminitis, penetration of sole and rotation
52
What are the 4 surfaces of the navicular bone?
Proximal, distal, articular, and flexor
53
T/F: The articular surface of the navicular bone has a prominent central ridge--the central eminence
FALSE--the **flexor** surface has the central ridge
54
What do the extremities of the navicular bone look like?
Spindle shaped and blunted
55
The navicular bone has no more than ___ synovial invaginations (radiolucent) that are relatively triangular in shape
7
56
What separation on the navicular bone should be detected?
A clear cortical medullary separation
57
What is circled?
Navicular bone
58
4 diseases of the navicular bone?
* Navicular degeneration * Fractures * Navicular sepsis * DJD
59
T/F: There is no universal agreement as to the clinical importance of all radiographic signs of navicular disease
TRUE
60
What are all these signs indicative of?
Navicular disease
61
What's going on here?
Enthesophyte and navicular remodeling
62
List allllllll the problems
Severe remodeling, irreglar distal surface, multiple irregular synovial invaginations, mineralization of ligaments (enthesophyte) of the navicular bone
63
Diagnosis?
Navicular fracture ## Footnote **\*Make sure line stops at navicular bone--could just be an artifact\***
