Q

What is carpel tunnel? What test can help it be diagnosed?

A
  • Pain in the carpal tunnel/hand due to excess pressure in your wrist compressing the median nerve where it passes through the retinaculum
  • Most common peripheral nerve entrapment compressing the medial nerve as it passes through the carpal tunnel causing sensory and motor deficits beyond this point (into the hand)
  • Upper limb neurological tension test, compression test, tinnels test and phalens test

Q

What is De Quervains/Tenosynovitis

A

Inflammation of the synovium of the abductor pollicis longus and extensor polis brevis tendons as they pass in their synovial sheath in a fibro-osseous tunnel at the level of the radial styloid

Q

What is the difference between medial and lateral epicondylitis? What tests can be used for each?

A
  • Lateral epicondylitis is more common and is due to tendinopathy of the forearm extensors due to overuse or overloading while medial is the same but overuse of the flexor compartment
  • Lateral tests include: maudsleys and cozens
  • Medial tests include: Resisted isometric wrist flexion, vagus force testing

Q

What ortho tests should be used for tennis elbow/ lateral epi?

A
  • Cosens

- Maudsleys

17
Q

What ortho tests should be used for golfers elbow/ medial epi?

A
  • Valgus test (group 2 MCL would be weakened or affected)
  • Gripping weakness
  • Ulnar nerve symptoms associated in 20% of patients
18
Q

What order should you treat epicondylitis?

A
  1. Education, Rest, Maintaining ROM
    - education the patient about what may be causing the pain
    - De-loading the tendons/ stopping aggravating factors
    - NSAIDs and analgesics
    - possible brace and splints
  2. Progressive strengthening and stretching
    - isometric
    - eccentric/ concentric
    - Dynamic
19
Q

Population/ aetiology of lateral epicondylitis

A
  • 40 - 50yo
  • insidious/ overuse/ no incident
  • wrist extension movements: mouse, screw drivers, tennis players
  • pain radiating down posterior aspect of forearm
  • tenderness over site
20
Q

Pathophysiology of DeQuervains?

A

The tendons of the abductor pollicis longus and the extensor pollicis brevis are tightly secured against the radial styloid by the overlying extensor retinaculum. Any thickening of the tendons from acute or repetitive trauma restrains gliding of the tendons through the sheath.

21
Q

Some historial factors for DeQuervains?

A
  • Patients are commonly mothers of infants 6-12 months (repetitive lifting of the baby as it becomes heavier)
  • Texting
  • Athletes /sports people
22
Q

What are the clinical features of FOOSH?

A
  • Pain and swelling in the snuff-box, at the base of the thumb
  • Pain is aggravated by movements of the wrist and thumb, especially extension
  • Pain not always severe, may seemed like that of a generalized sprain
  • Swelling over the snuff box, 1st metphal joint
  • Wasting in the right hyper thenar muscles
  • POP in snuff box, over carpal tunnel, hyper thenar
  • ROM–
23
Q

What are the likely findings of a FOOSH injury?

A

Examination: Decreased wrist ROM in all directions in comparison to the other wrist and pain on thumb extension active & passive

Neuro testing:
Decreased sensation to light touch over the thenar skin and 1st & 2nd fingers
Weakness is noted on right thumb adduction & opposition

Diagnostic tests:
• +ve scaphoid shift/provocation
• +ve carpal tunnel tests (Tinnels & Phalens) due to bleeding and oedema
• +ve Finkelstien test
• +/-ve vascular test - Allen’s
• Upper limb neural tension tests (+TOS)
• Plain film x-ray (CT/MRI may be indicated if suspicious of avascular necrosis)

24
Q

Where does the force transmit when FOOSH + falling forward?

A

distal carpals, radius and possibly AC joint

25
Q

Where does the force transmit when FOOSH + ongoing vague symptoms?

A

Suspected wrist sprain

26
Q

Where does the force transmit when FOOSH + behind body of the line?

A

force transmits to elbow

27
Q

Where does the force transmit when FOOSH + locked elbow?

A

radial head and distal humerus

28
Q

What is the most common carpal bone #?

A

Scaphoid

29
Q

How long will a foolish approx take to recover?

A

4 - 8 weeks

30
Q

What are the clinical signs that you may suspect a foosh?

A
  • persistant wrist pain following FOOSH
  • pain + swelling in snuff box
  • Agg: thumb and wrist movements (especially thumb extension)
  • Not always severe, Ssx of general sprain can be present
