Chapter 7 Shoulder Flashcards
Bones making up the shoulder?
Clavicle, scapula, humerus
Joints of the shoulder/
Scapulothoracic (pseudo-joint), AC joint, glenohumeral, SC joint
Rotator cuff muscles?
Supraspinatus, Infraspinatus, teres minor, Subscapularis (SItS)
Primary flexor?
Deltoid (anterior portion)
Primary abductor?
Deltoid (middle portion)
Primary extensors?
Lat dorsi, teres major, deltoid (posterior portion)
Primary adductors?
Pec major, lat dorsi
Primary external rotators?
Infraspinatus, teres minor
Primary internal rotator?
Subscapularis
Subclavian artery passes bt which 2 muscles?
Anterior and middle scalenes–contracture of these muscles affects arterial supply but not venous drainage
Subclavian vein passes where?
Anterior to anterior scalene
When does subclavian a become axillary a?
Lateral border of 1st rib
When does the axillary a become the brachial a?
Inferior border of teres minor
1st major branch of brachial a?
Profunda brachial a–accompanies radial n in its posterior course of radial groove
Where does brachial a divide into ulnar and radial aa?
Under bicipital aponeurosis
What becomes the deep palmar arterial arch?
Radial a
What becomes the superficial palmar arterial arch?
Ulnar a (Ulnar is Up in the palm)
Tx technique to relieve lymph congestion of UE?
1) Open thoracic inlet
2) Redome diaphragm
3) Posterior axillary fold technique
Nerve roots of brachial plexus?
C5-T1
Degrees of motion during arm abduction?
120 degrees due to glenohumeral motion, 60 degree due to scapulothoracic motion
For every 3 degrees of abduction…
Glenohumeral joint moves 2 degrees and the scapulothoracic joint moves 1 degree
Most common somatic dysfunction of shoulder?
Restriction in internal and external rotation
Second most common somatic dysfunction of shoulder?
Restriction in abduction
Least common somatic dysfunction of shoulder?
Restriction in extension
