- congenital
- acquired
traumatic
developmental
inflammatory
infective
metabolic
degenerative
neoplastic
postural
idiopathic

2

Symptoms of carpal tunnel syndrome

numbness
altered sensation
Dysaesthesia (abnormal unpleasant feeling)
clumsiness
night awakening
pain

3

Special test for Carpal tunnel syndrome?

Tinnels test
(hammer hitting carpal tunnel area)
Phalens' test (hold hands back to back)

4

Investigations for carpal tunnel syndrome?

Nerve conduction studies
PV
X-ray
T4
blood glucose

5

Why would you check T4 levels in carpal tunnel syndrome?

Hypothyroidism can cause carpal tunnel syndrome

6

Can hypothyroidism cause carpal tunnel syndrome?

Yes

7

Why might you check glucose in carpal tunnel syndrome?

Diabetes/pre diabetes can cause carpal tunnel syndrome

8

Non-operative treatment for carpal tunnel syndrome

corticosteroid injection
splint
workplace task modification

9

How is your wrist kept in the splint for carpal tunnel syndrome?

Wrist is kept in flexion

10

Indications for decompression for carpal tunnel syndrome?

Failed conservative treatment
Constant numbness
Weakness
Operative treatment:
Standard open carpal tunnel release (endoscopic or mini-open)
Arthroscopic

11

Opposition and adduction of thumb in carpal tunnel syndrome?

May have weakness, may not be able to do it very well (opposition and adduction of thumb= when you pinch your thumb and pinky together)

12

Which fingers are likely to tinger in cubital tunnel syndrome?

The ring and little fingers
-Pain and numbness in elbow
-Eventually you may develop a claw like deformity if you have really bad cubital tunnel syndrome

13

Which nerve is compressed in cubital tunnel syndrome?

The ulnar nerve

14

Which muscles in the hand does the Ulnar nerve supply?

The ulnar nerve is the principle motor supply to the intrinsic muscles of the hand

15

Froment's sign in cubital tunnel syndrome?

Positive froments sign caused by ulnar nerve palsy
(i.e. when they grip something with their thumbs, it will bend)

16

Treatment for cubital tunnel syndrome

Splint
Neurolysis (causes temp. degeneration of nerve fibres for pain relief)
Anterior transposition
subcutaneous
submuscular
intra-muscular
medial epicondylectomy
