11
Q

Why is the fibrous capsule of the GH joint open in two places? (two reasons)

A
  1. Allow biceps brachii T passage

2. Communicate with subscapular bursa

16
Q

Transverse humeral L

A

Greater humeral tubercle -> lesser humeral tubercle (encapsulates long head of biceps brachii in intertubercular groove)

17
Q

Coracoacromial arch

A

Coracoid process + coracoacromial L + acromion

18
Q

Where is the GH joint most susceptible to dislocation, and why

A

Anterior/inferior; bc coracoacromial arch prevents superior dislocation

19
Q

Elbow joint type

A

Ginglymus synovial joint

20
Q

What two joints in the elbow have continuous synovial membranes?

A

Elbow joint proper + proximal radioulnar joint

21
Q

Two elbow ligaments and their attachments

A

Ulnar collateral L: medial humeral epi -> coronoid process of ulna
Radial collateral L: lateral humeral epi -> blends with annular L of radial head

22
Q

Three bands of the UCL of elbow and why theyre important

A
  1. Anterior band: strongest
  2. Posterior band: weakest
  3. Oblique band: deepens socket for humeral trochlea
23
Q

Direction most common for elbow dislocation and what usually tears?

A

Posterior, UCL tear

24
Q

Common force causing elbow dislocation

A

Force transmitted along long axis of forearm

25
Q

Olecranon bursae: three bursae

A
  1. Subtendinous olecranon bursa
  2. Intratendinous olecranon bursa
  3. Subq olecranon bursa
26
Q

Two most common elbow bursa to become inflamed + their locations

A
  1. Subq olecranon bursa: in subq CT over olecranon

2. Bicipitoradial bursa: between biceps brachii T + radial tuberosity

27
Q

Three other names for subq olecranon bursitis

A

Students elbow, dart throwers elbow, miner’s elbow

28
Q

Three articulations between radius and ulna

A

Proximal, distal, and middle radioulnar joints

29
Q

Proximal and distal radioulnar joint type

A

Trochoid synovial joint

30
Q

Middle radioulnar joint type

A

Syndesmosis

31
Q

Primary site of supination and pronation for radioulnar joints

A

Proximal radioulnar joint

32
Q

Where is the synovial membrane of the proximal radioulnar joint

A

Lines underside of annular L

33
Q

Sacciform recess

A

Two of them - Small pocket of synovium that protrudes out from under annular L + small pocket out from under fibrous capsule

34
Q

Annular L attachments

A

Coronoid process of ulna -> around radial head -> inserts back onto ulna

35
Q

Dislocation of radial head out of annular L

A

Typically from pulling on arm of child, sometimes called Nursemaid’s elbow or pulled elbow

36
Q

Does the interosseous membrane limit pronation and supination?

A

No
