Q

In a shoulder examination, which special test might you do to look for shoulder impingement?

A

Hawkin’s test - looking for pain when the elbow is flexed to 90 degrees, the shoulder is flexed to 90 degrees and the arm is internally rotated. This narrows the subacromial gap and hence will elicit the symptoms of supraspinatus impingement.

Q

In a shoulder examination, how might you test whether there was a tear in the supraspinatus?

A

Drop arm sign - passively abduct the arm and then ask patient adducts it slowly. If there is damage to the supraspinatus, they will feel a catching pain at 30 degrees of abduction.

Q

How would you treat a patient with a tear of the one of the rotator cuff muscles?

A

Non-operative:
Physio
Steroid Injection

Operative:
Repair laparoscopically
Reverse polarity replacement - the ball is placed where the glenoid cavity was and the cup is attached to the humerus. This moves the point of leverage medially and allows the deltoid muscle to play a greater role in initiating abduction.

A

Pain
Itching
Inability to hold objects

58
Q

What is the underlying pathology in Dupuytren’s contracture?

A

The palmar fascia becomes abnormally thick due from a change of collagen type. Normally, the palmar fascia consists of collagen type I, but in Dupuytren sufferers, the collagen changes to collagen type III, which is significantly thicker than collagen type I.

Q

What is involved in the table top test as part of the hand exam?

A

Patient places his hand on a table. If the hand lies completely flat on the table, the test is considered negative. If the hand cannot be placed completely flat on the table, leaving a space between the table and a part of the hand as big as the diameter of a ballpoint pen, the test is considered positive.

A 
Weakness in abducting thumb
Numbness of the thumb, index, middle and radial half of the ring finger. 
Worse at night
Wrist pain
Loss of grip strength
66
Q

On examination of the hand, what might you notice in someone with suspected carpal tunnel syndrome?

A

Wasting of thenar eminence
Pain during Phalen’s test
Pain during Tinnel’s test
Parasthesia or loss of sensation over the radial border of the index finger.

67
Q

What is Phalen’s test?

A

Hyperflexion of the wrist, by placing dorsal side of patients hands together. Pain is a positive result.

68
Q

What is Tinnel’s test?

A

Tapping repetitively on palmar aspect of the wrist to reproduce pain, which would be a positive result.

69
Q

What are the treatment options for someone with carpal tunnel syndrome?

A

Non-operative:
Pain relief
Splint at night
Steroid injection

Operative:
Carpal tunnel release (decompression)

70
Q

Will symptoms be relieved immediately following carpal tunnel release?

A

No. Compression damage will take a long time to heal so symptoms will persist as nerve is repaired.

71
Q

Where do you test sensation for the radial nerve?

A

First radial web space on the dorsal aspect of the hand

72
Q

Where do you test sensation for the ulnar nerve?

A

Ulnar border of the little finger

73
Q

Where do you test sensation for the median nerve?

A

Radial border of the index finger

74
Q

What is cubital tunnel syndrome?

A
