In Class Terms

Question 1

What is osteomyelitis?

Answer 1

inflammation of the medullary cavity, the periosteum, and cortex

cannot happen in the coffin bone

Question 2

What is osteitis

Answer 2

inflammation of a bone, the periosteum and cortex

bucked shins

pedal osteitis (PIII)

Question 3

What is lysis

Answer 3

decreased bone/breakdown of bone

creates radiolucency

Question 4

What is sclerosis?

Answer 4

increasing amount of bone, laying down of bone

osteoarthritis

creates radiopaque

when fixing a break, a callus is what is left over after sclerosis

Question 5

What is pedal?

Answer 5

coffin bone/foot

Question 6

What is a sequestrum?

Answer 6

piece of dead bone

non articular: not associated with a particular joint

blunt force trauma

avascular

infection

cannon bones

carpus and tarsus down is the most common area for the sequestrum

it takes 2-3 weeks for a sequestrum to show up on radiograph

Question 7

What is avascularity?

Answer 7

no longer has a blood supply

Question 8

What is a chip fracture?

Answer 8

associated with joints, intraarticular (IA)

one articular surface is effected

radial carpal bone (flexed lateral radiograph)

Proximal PI

Question 9

What is a slab fracture

Answer 9

associated with joints, intraarticular (IA)

two articular surfaces are effected

3rd carpal bone (skyline radiograph)

Question 10

What is idiopathic?

Answer 10

unknown cause

Question 11

What is iatrogenic?

Answer 11

caused by humans

when infection is caused after surgery

when needs get stuck in a joint and are not sterile

Question 12

What is a callus?

Answer 12

bone bridge across a fracture line

Question 13

What is condylar?

Answer 13

articular fracture

thoroughbreds get in on the lateral side and the left bone gets more impact

treat with screwing the two pieces back together

Question 14

What is transverse?

Answer 14

fracture is the diaphysis

bone plate for treatment

Question 15

What is synovitis?

Answer 15

Inflammation of the synovial membrane

effusion is the clinical sign

Question 16

What is capsulitis?

Answer 16

inflammation of joint capsule

Question 17

What is arthritis?

Answer 17

inflammation of the joint

Question 18

What is osteoarthritis?

Answer 18

inflammation of the joint with bone involvement (OA)

also known as degenerative joint disease (DJD)

Question 19

What is arthroscopy?

Answer 19

less invasive surgical procedure on a joint

to see inside a joint with a camera

2+ portals - camera and instrument

Question 20

What is arthrotomy?

Answer 20

opening up the joint to see what is wrong with it

gross visualizatoin

Question 21

What is osteochondritis dissecans?

Answer 21

osteochondrosis: has to do with the mineralization of the cartilage

cartilage transforming to be bones when the horse is growing

Question 22

What is osteochondrosis?

Answer 22

failure of bone to ossify

Question 23

What is OCD?

Answer 23

osteochondritis dissecans

Question 24

What is SBC?

Answer 24

subchondral bone cyst

Question 25

What is ankylosis?

Answer 25

when the horse shuts down joints the vet will want to speed up the process of this chemical injection (ethyl alcohol): increases the overall inflammatory response to a crazy degree to speed up the process drilling/screwing: creates so much destruction that it increases the inflammation in the joint to heal

Question 26

What is arthrodesis?

Answer 26

surgically closing the joint

Question 27

What is an osteophyte?

Answer 27

bone spur laying down more bone on top of bone new bone within a joint

Question 28

What is an enthesiophyte?

Answer 28

new bone associated with soft tissue structures at their origin or insertion looks like a bone spur but is outside of the joint

Question 29

What is an avulsion?

Answer 29

piece of bone pulled off by soft tissue

Question 30

What are shorter limbs caused by?

Answer 30

these happen when a horse fractures a proximal limb bone all of the muscle associated with the area they fracture and then the bones shift and shear next to one another
