flexion normal range
150-180
extension normal
50-60
abd normal
150-180
add normal
30-50
ER normal
90
IR normal
50 -60
GH flexion
120
GH abd/add
120
GH ER and IR
90 and aorund 65
GH and the scapular thoracic joint flexion
120 - GH
60 - scapular thoracic
supraspinatus insterion
superior facet of the greater tubercle
infraspinatous instertion
middle facet of the greater tubercle
teres minor instertion
inferior facet of the greater tubercle
subscapularis insertion
lesser tubercle of the humerous
what is the scapular plane
35-45-degrees from the forntal plane
what is the gleniod labrum
fibrocartiginous ring that arrises from the glenoid
where does the long head of the biceps attach to
the labrum
SGHL resists what
ing and ant/post translation
MGHL resists what
anterior translation and ER
IGHL parts
anterior band
posterior band
axillary pouch
generally what does the IGHL resist
inf and ant/post translation
anterior band of the iGHL
ER
posterior band of the IGHL
IR
what is the function of the axillary pouch
acts as a resistance to abd after 90-degrees
also when we twist the shoulder
what does the axiallary pouch look like when the arm is at rest
it is folded up on itself
what are the rotator cuff muscles
supraspinatus
infraspinatus
teres minor
subscapularis
resting position of the scapula
5-10 of upward rot
35-degrees of internal rot
action of the supraspinatus
abd and some ER
assists the deltoid in abd - helps elevate the arm and counteracts the superiorly directed forces generated by the deltoid a
action of the infra
ER primary
action of the teres minor
ER primary
action of the subsacapularis
IR primary
and primary anterior compressor
supra type of compressor
superior compressor
infra type of compressor
posterior compressor
teres minor type of compressor
posterior compressor
subscap type of compressor
anterior compressor
depresses the humeral head
supra nerve
suprascapular nerve
infra nerve
suprascapular nerve
teres minor nerve
axillary nerve
subscapularis nerve
U/L subscapular nerve
function of the rotator cuff
approximate the humerus to the glenoid
what depresses the humeral head
subscap
teres minor and infra
what does the supra head the deltoid with
abd
creates a superior compressive force into the glenoid fossa
capsular pattern of the shoudler
ER> GH-abd > IR
