Joint injections

Question 1

what are the 4 joint injections of the forelimb? give the pouches associated with each

Answer 1

1. radiocarpal joint: dorsal pouch and palmarolateral pouch
2. fetlock joint: palmar pouch
3. pastern joint: dorsal pouch
4. coffin joint: dorsal pouch

Question 2

what are the 5 joint injection sites of the hindlimb? give the pouches associated with each

Answer 2

1. tibiotarsal/tarsocrural joint: dorsal
2. tarsometatarsal joint: plantolateral approach
3. fetlock joint: palmar pouch
4. pastern joint: dorsal pouch
5. coffin joint: dorsal pouch

Question 3

describe the location of the dorsal and palmarolateral pouches of the radiocarpal joint

Answer 3

dorsal pouch: by either side of extensor carpi radialis
palmarolateral pouch: use the accessory carpal bone as a landmark

Question 4

which two carpal joints communicate?

Answer 4

middle carpal and carpometacarpal

Question 5

describe the palmar approach to the fetlock/metacarpophalangeal joint (5)

Answer 5

1. proximal to collateral sesamoidean ligament
2. distal to splint bone button
3. cranial to susp ligament
4. adjacent to palmar surface of cannon bone

Question 6

describe the dorsal pouch of the pastern joint (aka PIP)

Answer 6

between the long pastern bone and the short pastern bone

Question 7

describe the dorsal pouch of the coffin joint

Answer 7

between P2 and P3

Question 8

what are the 3 approaches to the dorsal pouch of the coffin joint?

Answer 8

1. dorsal parallel approach
2. dorsal perpendicular approach
3. dorsolateral approach

Question 9

which two tarsal joints communicate?

Answer 9

tibiotarsal and proximal intertarsal

Question 10

what are the 4 joints of the hock?

Answer 10

1. tibiotarsal
2. proximal intertarsal
3. distal intertarsal
4. tarsometatarsal

Question 11

describe the landmarks of the dorsomedial approach to the dorsal pouch of the tarsocrural joint

Answer 11

landmarks are the cranial branch of the medial saphenous vein and the medial malleolus of the tibia

Question 12

describe the landmarks of the plantolateral approach to the tarsometatarsal joint

Answer 12

landmarks are the head of the lateral splint bone (MT4) and the SDFT

Question 13

describe the collateral sesamoidean approach to the palmar pouch of the fetlock joint

Answer 13

landmark is proximal to the collateral sesamoidean ligament; when the limb is flexed there will be a depression between the sesamoid bone and the lateral condyle of the cannon bone
