1

surgical immobilization of a joint by fusion of the adjacent bones

Arthrodesis

2

What are the indications for

arthrodesis of the PIJ (pastern joint)?

High ring bone

Pastern luxation

P2 fracture

Pastern septic arthritis

3

What are the 3 surgical techniques that can be used to

accomplish arthrodesis of the PIJ (pastern joint)?

Trans-articular lag screws

Dorsal plate (DCP or LCP)

Screws AND Plate

4

What is the best way to accomplish

arthrodesis of the PIJ (pastern joint) and why?

Transarticular lag screws + dorsal plate

 

better stability and comfort

less time in cast and hospital

less periarticular bone formation on dorsal aspect

5

What type of incision is used in

arthrodesis of the PIJ (pastern)?

Inverted T incision

6

What are the landmarks for the longitudinal portion

of the inverted T incision?

Junction of the proximal and middle third of the proximal phalanx

to

2 cm above the coronary band

7

What structure is visualized upon

inverted T incision?

Common Digital Extensor (CDE) tendon

8

This type of incision is used to transect the

common digital extensor tendon

in order to elevate and reflect it distally

Inverted V incision

9

For arthrodesis of the PIJ/Pastern joint,

after removing any bony proliferations on the dorsal

surface and the cartilage in the joint capsule,

__________ of the subchondral (P1,P2) bone plates

is done using a 2.5 mm drill bit

Osteostixis (surgical puncture of a bone)

10

How many osteostixis are made 

in P1 and P2 for screw placement

in arthrodesis procedure?

TWO glide holes in P1

ONE thread hole in P2

11

After drilling the holes in P1 and P2,

you need to _______ and tap

and enter P1 at an angle to get into P2

countersink

12

What has a better success rate for pastern arthrodesis?

Forelimb or Hindlimb?

HIND limb = 95% success

13

What is the forelimb success rate for pastern arthrodesis?

81%

14

This type of imaging is a must

intra and post op for

pastern arthrodesis sx.

RADS

15

Even though the success rate for pastern arthrodesis

is so high, complications are life threatening and costly.

Name some complications associated with this sx.

cast discomfort

implant (plate) failure

instability

infection (staphylococcus)

pressure sores

ischemia of distal limb

laminitis

16

_______ are the mainstay for

management of complications for pastern arthrodesis

NSAIDS

17

What meds are used to manage complications of

pastern arthrodesis sx?

Nsaids

Morphine, Butorphanol

Bupivicaine

Lidocaine

Gabapentin

Aspirin, Acepromazine, Pentoxyphylline
