Upper extremity Flashcards
The subclavian artery passes between what muscles?
anterior and middle scalenes
The subclavian Vein passes anterior to what muscle
anterior scalene
The subclavian artery becomes axillary where?
lateral border of first rib
The axillary artery becomes the brachial artery where
an the inferior border of the teres minor muscle
What is the first major branch of the brachial artery and what does it accompany? also where does it run?
- Profunda brachial artery
- accompanies radial nerve
- posterior course of radial groove
The brachial artery divides into the ulnar and radial arteries where?
under the bicipital aponeurosis
The radial artery courses the lateral aspect of the forearm supplying blood to the elbow, wrist, and dorsal aspect of the hand and eventually formed most of what
deep palmar arterial arch
The ulnar artery courses the medial aspect of the forearm supplying blood to the elbow, wrist, dorsal aspect of the hand and eventually forming most of what
superficial palmar arterial arch
Describe the different joints involved in should abduction
- normally can abduct to 180 degrees
- 120 due to glenohumeral motion and 60 due to scapulothoracic
- therefore, for every 3 degrees of abduction, the glenohumeral joint moves 2 and scapulothoracic moves 1
What is the most common SC joint dysfunction
clavicle anterior and superior on the sternum
What is the most common AC joint dysfunction
Clavicle superior and lateral on acromion
Test for thoracic outlet by scalenes?
Adson’s
Test for thoracic outlet by clavicle and rib 1
military posture test
Test for Thoracic outlet by pec minor
hyperextension test
What degrees of abduction usually exacerbate supraspinatus tendinitis
60-120
What is the most common shoulder dislocation and what nerve is injured
- anterior and inferior
- Axillary
What are the primary supinators of the forearm what what nerve innervates each?
- Biceps: musculocutaneous
- Supinator: radial
What nerve innervates the pronators of the forearm
median
the muscles are the thenar eminence are innervated by the median nerve except for which one?
Adductor pollicis brevis: ulnar nerve
Normal carrying angle for men
5 degrees
normal carrying angle for women
10-12
What is cubitus valgus
- carrying angle > 15
- abduction of the ulna
What is cubitus varus
carrying angle of < 3
-adduction of the ulna
