Post Shoulder Flashcards
main functions of the rotator cuff muscles
- holding/steadying humeral head in glenoid cavity
- maintaining it in suitable apposition to glenoid cavity
what do tendons of the rotator muscles combine to make on the humerus
tendons blend with and reinforce fibrous capsul of shoulder jt.
(protects joint and gives it stability)
where is the capsular attachment on the huerus
anatomical neck of lesser tubercle and goes to lowesr point of surgical neck and will travel over supraspiatus attachment
on the post surface of humerus what attaches on inf and middle facet
inf- teres minor
middle- infraspinatus
during the initial stages of abduction rotor cuff muscles counteract what
counteract strong upward pull of deltoid which would cause humeral head to slide up
what resists the tendency for the humeral head to be translated down wards in the glenoid cavity
supraspinatus (not delt)
when there is a rupsture of the supraspinatus tendon what will happen to associated bursae
Subacromial bursa distended with inflammatory fluid into subdelt bursa
what does the suprascapular artery and vein run over and what does it supplu
run over the superior transverse scap ligament
-supply supraspinatus, infraspinatus and shoulder jt.
what space does the axillary nerve travel through to get to the post shoudler
quadrangular space
what travels thru medial triangular space and what does it form
circumflex scapular artery forming astemosis
what runs through the lat triangular space a+v
radial n and deep brachial artery (supplys blood supply for radial)
blood supply for axillary n
post circumflex
blood supply for suprascap n
circumflex scapular artery
where should you not do cupping theraoy
dorsal scapula due to astemosis
what arteries make scapular arterial astemoses (5)
- Scapular A
- Dorsal scapular A
- Subscapular
- Circumflex scapular
- Thoracodorsal
