clavicle articulates with the sternum

scapulothoracic joint

not a true joint, but showd the relationship between the scapula and the ribcage

Scapulohumeral joint

(glenohumeral or shoulder joint)

external rotation

shows greater tubercle laterally, humeral epicondyles parallel to ir.

orthostatic breathing

not holding breath- makes ribs blurry to better show scapula

ap and ap axial clavicle positioning

Erect or supine. Arms at side, chin raise, and posterior shoulder in contact with IR

ap scapula positioning

• Erect or supine. Top of IR 2" above shoulder, and lateral border of IR should be 2" from lateral margin of ribs. Abduct arm 90° and supinate hand

lateral scapula positioning

Erect or recumbent, Face patient toward IR in anterior oblique position. Have patient reach across front of chest and grasp opposite shoulder (demonstrates body of scapula) or have patient drop affected arm, flex elbow, and place arm behind lower back with arm partially abducted (demonstrates acromion and coracoid processes.

lateral scapula

should have an imaginary perpendicular line between superior border of scapula and ac joing

ap clavicle cr

perpendicular to midclavicle

ap axial clavicle cr

15°-30° cephalad perpendicular to midclavicle

ap scapula cr

mid scapula, 2 in inferior to coracoid process or level of axilla, and 2 in medial from lateral border of patient

lateral scapula cr

midvertebral border
