medial

20
Q

border of the scapula that is closest to the midline next to the axillary

A

lateral

21
Q

the upper most portion of the scapula

A

superior

22
Q

3 angles of the scapula

A

lateral, superior, and inferior

23
Q

sometimes called the head of the scapula, is the thickest part and ends with the glenoid cavity. the head of the humerus articulates with this part of the scapula and is known as the scapulohumeral joint or just shoulder joint

A

lateral angle

24
Q

refers to the superior angle of the medial border

A

superior angle

25
Q

refers to the inferior angle of the medial border

A

inferior angle

26
Q

part of the scapula that is also known as the blade and is arched for strength

A

body

27
Q

called the costal surface because it is closest to the ribs

A

anterior surface of scapula

28
Q

a long curved process of the scapula that extends laterally over the head of the humerus

A

acromion

29
Q

a thick beak like process that projects anteriorly beneath the clavicle.

A

corocoid process

30
Q

a notch on the superior border and partially made up by the base of the corocoid process

A

scapular notch

31
Q

posterior surface of the scapula

A

dorsal surface

32
Q

on the posteror of the scapula this is a prominent structure. it starts at the medial border and finishes at the acromion.

A

scapular spine

33
Q

the ridge of the scapular spine

A

crest

34
Q

two fossa’s of the scapula

A

infraspinous (below) and supraspinous (above) The fossa’s are where muscles attach.

35
Q

the easiest bone in the body to break

A

clavicle

36
Q

you would use the same kVp and mAs on a ____ as you would on ___

A

Clavicle; shoulder

37
Q

a compression fx. or defect involving the articular surface of the humeral head. Often associated with shoulder trauma and/or anterior dislocations of the shoulder

A

Hill-Sachs Defect, no adjustment to technique

38
Q

a bony fragment is wedged into another fragment. Common in shoulder and hip fractures

A

impacted Fx.

39
Q

fx. involving the joint surface

A

Articular fx.

40
Q

fracture due to bone destruction caused by disease. Cancer is the primary cause. The fx. may not be caused by trauma, but by routine activities like putting on a coat.

A

Pathologic Fx.

41
Q

a fx accompanied by a bone out of joint

A

Fracture Dislocation

42
Q

distal clavicle is usually displaced superiorly causing widening of the AC joint space

A

AC dislocation

43
Q

traumatic injury to one or more of the muscles that make up the rotator cuff

A

rotator cuff tear

44
Q

inflammatory condition of the tendon

A

tendonitis

45
Q

inflammation of the bursa or fluid-filled sacs enclosing the joints

A

bursitis

46
Q

dislocation of a bone from a joint

A

dislocation/luxation

47
Q

partial dislocation

A

subluxation
