Radiculopathies In Class

Question 1

Answer 1

Question 2

Because you see both motor and sensory deficits, it cant be something purely motor like ALS

Answer 2

Froment sign

DDx; C8 radiculopathy, lower trunk plexopathy, ulnar neuropathy (need MRI and EMG)

Question 3

Answer 3

Question 4

Answer 4

Question 5

Answer 5

Question 6

Key words: Radiating (think coming from a root), not very specific- positive straight leg raising test- this stretches nerves to elicit pain

Ddx: Sciatic nerve neuropathy (contains S1), S1 radiculopathy

Not on Ddx: peroneal neuropathy (doesnt affect ankle reflexes)

Answer 6

H-wave is basically an ankle reflex

Question 7

S1 compression causing CSF indention

DDx: C6 radiculopathy, median neuropathy, carpal tunnel

Answer 7

Digit 1 (C6), digit 3 (C7), and digit 5 (C8) (test question)

Note: no radiating

Question 8

Answer 8

Question 9

C6 compression

Answer 9

Dorsiflexor is mainly tibialis anterior (deep peroneal, L4-L5)

Evertors (deep peroneal, L5-S1)

Question 10

Answer 10

Question 11

How does carpal tunnel syndrome present (test question)?

Answer 11

Episodic whole hand numbness and tingling (episodic tingling first and then progresses to numbness as the nerve starts to die- less symptomatic)

Present upon awakening

Precipitated by sustained limb elevation (driving, etc.)

No pain until pronounced

Occurs spontaneously while seated at rest (occurs when youre doing nothing)

Question 12

Siatic gives off tibial nerve behind the tibia to innervate gastroc, soleus, and foot invertors
