14WHat is the function of the rotator cuff muscles?
The resting tone of these muscles acts to pull the humeral head into the glenoid fossa
15What are the axillary region borders and contents?
Axilla borders:
Anterior: pectoralis major and minor
Posterior: subscapularis, teres major, and latissumus dorsi
Medial: serratus anterior, thoracic wall (ribs)
Lateral: intertubercular sulcus of humerus
Apex: lateral border of rib 1, superior border of scapula,
and posterior border of
clavicle
Floor: axillary fascia and skin
Contents: axillary vessels, cords and nerves of the brachial
plexus, lymph nodes
(pathway to breast and upper limb)
16What are the parts of the axillary artery? What muscles seperares these into separates parts?
Some times life seems a pain
Suprathoracic
Thoraco-acromial
Lateral thoracic
Subscapular
Anterior circumflex of humerous
Posterior circumflex of humerous
Separated by the pectoralis MINOR (I, II, III)
17Colles fracture
fracture of the lower end of the radius with posterior
displacement of the
distal fragment and radial deviation of the hand at the wrist
- dinner fork deformity
18Smith fracture
same as smith except velar deviation
19Bartons
dislocation of distal raidcarpal joint
20Scaphoid fraction:
from fall of aBDucted outstretched hand
- complications- a vascular necrosis
21Lunate dislocation from fall on aDDucted hand. Lunate dislocates
anteriorly
complications- carpal tunnel syndrome, a vascular necrosis
22Draw out brachial plexsus
23What type of damage is there if there is a fracture of the medial epicondyle?
Potential damage to ulnar nerve and ulnar artery
24What part of the brachial plexus do upper trunk injuries impact?
The anterior and posterior divisions
25What are the loss of functions seen with upper brachial plexus injury?
Loss of abduction, external rotation, flexion of elbow and extension of wrist
26Which nerves are most effected by upper brachial plexsus injury?
Axillary c5, c6
Suprascapular C4, 5, 6
Radial C5, C6, C7, C8

Supraspinatus, infraspinatous, biceps, coracobrachialis, deltoid, and teres minor
28Which two symptoms are commonly seen with upper brachioplexsus injury?
(1) Waiter's tip position = extremity hands in medial rotation with wrist in flexion
(2) Unable to touch opposite should due to lat pectoral nerve issue
