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.

Q

What are the treatment options for a patient with ACJ arthritis?

A

Non-operative:
Physio

``` Tennis Golf Using a computer Driving DIY ```
36
How might a patient with suspected lateral epicondylitis present?
Unilateral pain and tenderness over the lateral epicondyle of the humerus. Radiating into the forearm Restricted dorsiflexion of the wrist and middle finger. Gradual and worsening onset of pain
37
What tests can be used to assess a patient with suspected tennis elbow?
Mill's test | Crozen's test
38
What is involved in Mill's test?
Clinician palpates the lateral epicondyle with one hand, whilst pronating forearm, fully flexing the wrist and extending the elbow. Pain indicates positive result.
39
What is involved in Crozen's test?
Clinician palpates the lateral epicondyle and stabilises the elbow with one hand, whilst the other hand puts the patient's arm into radial deviation and forearm pronation. The patient is then asked to resist wrist flexion. Pain indicates positive result.
40
What are the treatment options for someone diagnosed with lateral epicondylitis?
``` Non-operative: Rest Physio Splints Activity modification Steroid injection ``` Operative: Very rare
41
What is the proper name for golfer's elbow?
Medial epicondylitis
42
What is the underlying pathology in medial epicondylitis?
Inflammation of flexor forearm muscles
43
What is the cause of medial epicondylitis?
Repetitive micro trauma (stress) at the muscle-tendon junction and its origin at the medial epicondyle
44
What are the risk factors for medial epicondylitis?
Golf Tennis Driving DIY
45
How might a patient with suspected medial epicondylitis present?
Unilateral pain and tenderness over the medial epicondyle of the humerus. Radiating into the forearm Restricted plantar flexion of the wrist and pronation of the forearm. Pain doing things like opening jars. Gradual and worsening onset of pain
46
What tests can be used to assess a patient with suspected tennis elbow?
Golfer's elbow test
47
What is involved in the Golfer's elbow test?
The examiner palpates the medial epicondyle with one hand and grasps the patient’s wrist with his/her other hand. The examiner then passively supinates the forearm and extends the elbow and wrist.
48
What are the treatment options for someone diagnosed with lateral epicondylitis?
``` Non-operative: Rest Physio Splints Activity modification Steroid injection ``` Operative: Very rare
49
Which is more common, lateral epicondylitis or medial epicondylitis?
Lateral epicondylitis is much more common
50

Thumb CMC
51
What is the carpal bone involved in CMC arthritis at the base of the thumb?

57
How might someone with Dupuytren's contracture present? (Name 3 symptoms)
Pain Itching Inability to hold objects
58
What is the underlying pathology in Dupuytren's contracture?
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.
59

60
What test might you use to see whether someone with Dupuytren's contracture required interventional treatment?
Table top test
61
What is involved in the table top test as part of the hand exam?
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.
62
What are the treatment options for someone with Dupuytren's contracture?
Non-operative: Pain relief Radiation therapy Collagenase Injection (Xiaflex) ``` Operative: Needle aponeurotomy Limited Fasciectomy Wide awake fasciectomy Dermofasciectomy ```
63
What is carpal tunnel syndrome?
An entrapment neuropathy where inflammation in the carpal tunnel leads to an increase in pressure and then compression of the median nerve.
64
What are the components of the carpal tunnel?
4 tendons of the flexor digitorum profundus 4 tendons of the flexor digitorum superficialis Tendon of the flexor pollicis longus Median nerve
65
How might a patient with carpal tunnel syndrome present?
``` 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
On examination of the hand, what might you notice in someone with suspected carpal tunnel syndrome?
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
What is Phalen's test?
Hyperflexion of the wrist, by placing dorsal side of patients hands together. Pain is a positive result.
68
What is Tinnel's test?
Tapping repetitively on palmar aspect of the wrist to reproduce pain, which would be a positive result.
69
What are the treatment options for someone with carpal tunnel syndrome?
Non-operative: Pain relief Splint at night Steroid injection Operative: Carpal tunnel release (decompression)
70
Will symptoms be relieved immediately following carpal tunnel release?
No. Compression damage will take a long time to heal so symptoms will persist as nerve is repaired.
71
Where do you test sensation for the radial nerve?
First radial web space on the dorsal aspect of the hand
72
Where do you test sensation for the ulnar nerve?
Ulnar border of the little finger
73
Where do you test sensation for the median nerve?
Radial border of the index finger
74
What is cubital tunnel syndrome?
An entrapment neuropathy where inflammation in the cubital tunnel leads to an increase in pressure and then compression of the ulnar nerve.
