Flashcards in [weak legs & cord compression] Deck (20)
1

[cordcompression]: arm weakness suggest a lesion in the ... cord

cervical

2

[cordcompression]: what pattern of signs would there be at the level of the lesion

LMN

3

[cordcompression]: what pattern of signs would there be below the level

UMN
*remember tone/reflexes are often reduced in ACUTE cord compression*

4

[cordcompression]: UMN signs are expected below the level of the lesion - what 2 things may be different about these signs in ACUTE cord compression

Tone reduced
reflexes reduced

5

[cordcompression]: what is the commonest cause of spinal cord compression

secondary malignancy

6

[cordcompression]: what condition is associated with atlanto-axial subluxation

rheumatoid arthritis

7

[cordcompression]: what is the 1st line investigation.

Spinal MRI

8

[cordcompression]: What is the 1st line Tx for cord compression due to assumed secondary malignancy?

Dexamethasone IV 4mg/6hrs

9

[cordcompression]: how can you differentiate between cauda equina/conus medullaris and lesions higher up? (2)

the leg weakness is flaccid and areflexic below L1

10

[cordcompression]: conus medullaris lesion displays what urinary feature

EARLY urinary retention

11

[cordcompression]: lesions above L1 display urinary retention when?

late

12

[cordcompression]: conus medullaris syndrome causes what male specific symptom?

erectile dysfuncton

13

[cordcompression]: radicular pain down the legs is indicative of

cauda equina syndrome

14

[cordcompression]: reduced sphincter tone indicates damage to what strucuture?

cauda equina

15

[cordcompression]: lesions above ... result in leg weakness which is spastic and hyperreflexic

L1
(i.e. cauda equina)

16

[cordcompression]: ∆∆: why would you check B12 levels?

subacute combined degeneration of the spinal cord.

17

[cordcompression]: ∆∆: which columns are affected in SACDSC?

dorsal
corticospinal

18

[cordcompression]: why would you perform a CXR

primary lung malignancy

19

[cordcompression]: ∆∆: in unilateral foot drop you would suspect ... nerve palsy

common peroneal

20

[cordcompression]: ∆∆: what would be different about the presentation if MND was suspected

no sensory loss
