Chapter 7 Shoulder Flashcards
Joints of the shoulder/
Scapulothoracic (pseudo-joint), AC joint, glenohumeral, SC joint
Primary flexor?
Deltoid (anterior portion)
Primary extensors?
Lat dorsi, teres major, deltoid (posterior portion)
Primary external rotators?
Infraspinatus, teres minor
Subclavian artery passes bt which 2 muscles?
Anterior and middle scalenes–contracture of these muscles affects arterial supply but not venous drainage
When does subclavian a become axillary a?
Lateral border of 1st rib
1st major branch of brachial a?
Profunda brachial a–accompanies radial n in its posterior course of radial groove
What becomes the deep palmar arterial arch?
Radial a
Tx technique to relieve lymph congestion of UE?
1) Open thoracic inlet
2) Redome diaphragm
3) Posterior axillary fold technique
Degrees of motion during arm abduction?
120 degrees due to glenohumeral motion, 60 degree due to scapulothoracic motion
Most common somatic dysfunction of shoulder?
Restriction in internal and external rotation
Least common somatic dysfunction of shoulder?
Restriction in extension
Most common somatic dysfunction of SC joint?
Clavicle anterior and superior on sternum
“Step-off” seen at the AC joint?
Superior and lateral clavicle on acromion
Pathogenesis of supraspinatus tendinitis?
Continuous impingement of greater tuberosity against acromion as arm is flexed and internally rotated
“Painful arc”?
Pain exacerbated by abduction from 60-120 degrees in supraspinatus tendinitis
Aggravating factors in bicipital tenosynovitis?
Elbow flexion or supination
Location of pain in rotator cuff tear?
Tenderness just below tip of acromion
Etiology of frozen shoulder?
Prolonged immobility of shoulder
