Elbow Flashcards Preview

Phase II: Musculoskeletal > Elbow > Flashcards

Flashcards in Elbow Deck (15):
1

List the stabilising factors of the elbow joint

Static: Coronoid process, radial head, olecranon
Dynamic: muscles around the elbow joint

2

Describe the normal range of motion of the elbow joint

Elbow flexion 0-145 degrees
Supination 0-180 degrees

3

Define lateral epicondylitis

Pain in the region of the lateral epicondyle, which is exacerbated by active and resisted movements of the extensor muscles of the forearm.

4

Explain the pathology of lateral epicondylitis

Microtrauma to the insertion of the forearm extensor muscles, as a result of repetitive extensive of the wrist and grip-intensive activities.

5

What differential diagnoses should be excluded in suspected lateral epicondylitis

Referred pain from the cervical spine
Osteoarthritis of the elbow
Radial tunnel syndrome: compression of the posterior interosseous nerve

6

What test can be used to diagnose lateral epicondylitis?

Maudsley's test: pain in region of lateral epicondyle during resisted extension of the middle finger.

7

Describe the initial treatment options for lateral or medial epicondylitis

Activity modification
Analgesia: NSAIDs, paracetamol +/- codeine

8

Discuss the further treatment options for lateral or medial epicondylitis

Corticosteroid injection
Referral to physiotherapy
Wrist splints and straps

Extracorporeal shock wave therapy
Platelet-rich plasma

Surgical: debridement with tendon repair or release

9

Define medial epicondylitis

Pain in the region of the medial epicondyle, which is exacerbated by active and resisted movements of the flexor muscles of the forearm.

10

Explain the pathology of medical epicondylitis

Microtrauma to the insertion of pronator teres and the forearm flexor muscles, as a result of repetitive flexion of the wrist and grip-intensive activities.

11

What test can be used to diagnose medial epicondylitis?

Golfer's elbow test: pain around medial epicondyle on supination and extension of the wrist and elbow.

12

What is cubital tunnel syndrome?

Ulnar neuropathy due to compression of the ulnar nerve as it travels within the cubital tunnel.

13

Outline the borders of the cubital tunnel

Medial: medial epicondyle of the humerus
Lateral: olecranon process of the ulna
Roof: epicondylo-olecranon ligament

14

Describe the clinical findings of cubital tunnel syndrome

Weakness
Impaired grip strength
Tenderness over cubital tunnel
Tinel's sign
Numbness of medial side of hand

15

What initial treatment options exist for cubital tunnel syndrome?

Activity monitoring
Extension splinting at night
NSAIDs
Vitamin B6
