16
Q

Most commonly torn tendon of rotator cuff?

A

Supraspinatus Tendon

Can’t initiate abduction of arm, possible dislocation of glenohumeral joint

Calcium depositied in degenerative–eventually tear bursa, dumping down into joint cavity

17
Q

Quadrangle Space

A

Allows pasage of neurovascular supply from axilla to posterior scapular and arm regions

Contains:

Axillary Nerve

Posterior Circumflex Humeral Artery

18
Q

Damage to Axillary nerve?

A

Can be caused by break in head of humerus or dislocation of humerus

Results in weakends abduction of arm (15-120) and loss of cutaneous innervation to upper lateral arm

19
Q

Triangular Interval

A

Allows for passage of neurovascular supply from axilla to posterior scapular and arm regions

Contains:

Radial Nerve

Deep Brachial Artery

20
Q

Damage to radial nerve?

A

Can be caused by break in mid-shaft of humerus

Results in wrist drop and sensory loss of dorsum of hand

21
Q

Triangular Space

A

Passage for Circumflex Scapular Artery

22
Q

Anastomosis Around Shoulder Joint

A

Formed from branches of thyrocervical trunk of subclavian, uniting with subscapular branch of the 3rd part of axillary artery

Creates bypass for Axillary Artery

23
Q
A
24
Q

In the event subclavian is tied/torn/blocked, how does blood still reach the upper limb?

A

Suprascapular and transverse cervical arteries to the subscapular artery to enter axillary artery

25
Q

What area can ligations of the subclavian/axillary be made?

A

Anywhere between the thyrocervical trunk and subscapular artery

26
Q

Suprascapular Nerve

A

Branch of upper trunk (C5, C6)

Innervates supraspinatus / infraspinatus

27
Q
A
