Flashcards in Elbow Deck (16):
1

which three bones make up the elbow joint?

the humerus
the ulna
the radius

2

which ligament reinforces the elbow joint medially?

the ulnar collateral ligament

3

which ligament reinforces the elbow joint laterally?

the radial collateral ligament

4

what is the most common dislocation of the elbow?

posterior dislocation

5

what causes posterior dislocation of elbow?

fall onto hands with elbows flexed
hyperextension

6

what is the result of injury to the ulnar nerve?

numbness of the medial part of palm and medial one and a half fingers
weakness of flexion and adduction of wrist

7

what is simple elbow dislocation?

no fracture of bones around the elbow joint - normally ligamentous injury

8

what is complex elbow dislocation?

associated with fracture usually in the forearm
surgery often needed to fix the broken bone

9

what are the movements at the elbow?

flexion and extension

10

what is bursitis of elbow?

excessive repeated pressure and friction over the olecranon can use inflammation of the bursa
- this causes swelling of the bursa which may be visible and is painful on palpation

11

what is the anular ligament?

wraps around the head of the radius and allows rotation during pronation and supination of forearm

12

what are the movements of the proximal radioulnar joint?

supination and pronation

13

What is epicondylitis?

common site where the insertion of tendons into bones become inflamed

14

what is golfer's elbow?

insertions of wrist flexor tendons into the medial epicondyle become inflamed = golfer's elbow

15

What is tennis elbow?

insertion of the wrist extensor tendons into the lateral epicondyle becomes inflamed = tennis elbow
- local tenderness, pain that radiates into forearm
- treatment = rest/corticosteroids if pain severe

16

where do humeral fractures of occur?

in the surgical neck
- most common in elderly, may be associated with osteoporosis, axillary nerve injury - test deltoid function and sensation in regimental badge area
