Q

Lateral angle

A

Head of scapula, thickest part and ends with glenoid cavity. Head of humerus articulates with scapula (scapulohumeral joint/ shoulder joint)

20
Q

Superior angle

A

Superior angle of the medial border

21
Q

Inferior angle

A

Inferior angle of the medial border

22
Q

Body of scapula

A

Known as blade- is arched for strength

23
Q

Costal surface

A

Anterior surface of scapula- closest to ribs

24
Q

Acromion

A

Long curved process that extends laterally over head of humerus

25
Q

Corocoid process

A

Thick beak like process that projects anteriorly beneath clavicle

26
Q

Scapular notch

A

Notch on superior border and partially made up by base of corcoid process

27
Q

Dorsal surface

A

posterior surface of scapula

28
Q

Scapular spine

A

posterior of scapula (prominent structure). Starts @ medial border & finishes @ acromion

29
Q

Scapula’s 2 fossas

A

Infraspinous (below)
Supraspinous (above)

Where muscles attach

30
Q

Easiest bone in body to break

A

Clavicle

31
Q

KVP Shoulder Technique

A

70-80 With grid

32
Q

Shoulder Techniques

A

High MA, short exposure time, small focal spot, 40”

33
Q

AC Joint SID

A

72”

34
Q

Kyphotic geriatric patients

A

Vary techniques a bit lower to adjust osterportic bone bass. May need to angle because they can’t stand straight

35
Q

Hill Sachs defect

A

Compression fracture involving surface of humeral head.

Dislocations of the shoulder

36
Q

Impacted fracture

A

Bony fragment wedged into another fragment.

Shoulder & hip fractures

37
Q

Articular fracture

A

Involving joint space

38
Q

Pathological fracture

A

Due to bone destruction caused by disease (cancer).

May be caused by routine activities like putting on a coat.

39
Q

Fracture dislocation

A

Fracture accompanied by bone out of joint

40
Q

AC dislocation

A

Distal clavicle is displaced superiority causing widening of AC joint space

41
Q

Rotator cuff tear

A

Injury to 1 or more muscles that make up rotator cuff

42
Q

Tendinitis

A

Inflammation of tendon

43
Q

Bursitis

A

Inflammation of bursa or fluid filled sacs enclosing the joints

44
Q

Dislocation/ luxation

A

Dislocation of a bone from a joint

45
Q

Subluxation

A

Partial dislocation
