Shoulder Clinical Exam Flashcards
what are the four joints that are part of the shoulder?
acromioclavicular, sternoclavicular, scapulothoracic, glenohumeral
the shoulder joins sacrifices ____________ for _______________
stability; mobility
what is the static stabilizer of the shoulder?
glenoid labrum
what is the dynamic stabilizer of the shoulder?
rotator cuff muscles
what are the rotator cuff muscles?
supraspinatus, infraspinatous, subscapularis, teres minor
what kind of force do the big should muscles exert?
net upward force
what kind of force do the RC muscles exert to counteract the big shoulder muscles?
infermedial force
what is impingement syndrome?
if RC muscles dont oppose the big shoulder muscles, the supraspinatus, subacromial bursa, and other structures can get pinched between humeral head and acromion
what can cause an AC joint disruption?
an inferiorly directed overload force
what can cause a clavicular fracture in the middle of curve of clavicle?
a medially directed overload force
what ROM is the AC joint responsible for?
last 10-20 degrees of shoulder abduction
forward flexion
in what planes does the SC joint withstand lots of force?
transverse and saggital
in what plane does the SC joint allow almost limitless motion?
coronal
what are the ROMs that you will test?
F&E (hitler), ABD&ADD (ymca), horizontal ABD, ADD (izzard), INT and EXT rotation (wave dancer)
how do you test supraspinatus strength?
empty can/abduction - you stick pt’s arm out in front, turn thumb down, and passively flex arm up
