Conditions Involving One Limb

Question 1

Peripheral nerve injuries

Answer 1

HBC, IM inj, blows, bullets
Hyp/anesthesia, decreased reflexes
DX: LMN (dec reflex, dec tone, atrophy, dec feeling)
TX: glucocorticoide decrease pain, protect limb from self mutilation. Amputate >6mo

Question 2

Signs of Brachial Plexus Avulsion

Answer 2

C6T2
C67 shoulder
C8T1 elbow carpus
C8T1 lat thor n, dec panniculus
T1 vent root, horners (lose sympathetic and eye constricts)

Question 3

DX of Brachial Avulsion

Answer 3

History, CS

Question 4

TX of Brachial Avulsion

Answer 4

Protect
physiotherapy
Amputate >6mo
Prognosis generally poor, pain predicts recovery

Question 5

What are the different kinds of nerve root, peripheral nerve neoplasias?

Answer 5

Sheath tumors (neurofibromas/schwannomas)

Caudal cervical area (brachial plexus) peripheral nerve –> SC

Meningiomas, lymphomas, bony/soft tissue tumors –> compress and invade peripheral nerves

Question 6

Signs of Neoplasias

Answer 6

Monoparesis, atrophy, hyperpathia w limb palpation and manipulation

Usually very painful!

Question 7

DX of neoplasias

Answer 7

Myelo, CT and MRI, Histo w/ SX.

You see the golf tee sign withe Peripheral nerve sheath tumors

Question 8

EX of neoplasias

Answer 8

Resect them. Radiation and chemo don’t really work

Question 9

FCE signs

Answer 9

No pain, it's non progressive. 
Large breeds > small breeds
Min Schnauzers susceptible 
Peracute 60% during exercise
Paresis/paralysis - lateralizing
Often brachial/pelvic intumescence

LMN signs

Question 10

DX FCE

Answer 10

Signal, history, signs, NO INFLAMMATION, compressive sc diseases

myelography - don’t see anything

MRI

Question 11

TX FCE

Answer 11

Supportive therapy
Bladder - phenoxy, prazosin, tamsulosin, urecholine PPE
Some improve within week that have UMN
Most with LMN don’t improve
