The Shoulder joint sacrifices
|
Stability for mobility
|
|
|
Shoulder joint is known as
|
Glenohumeral joint
|
|
|
All rotator cuff muscles originate
|
from the scapula
|
|
|
All rotator cuff muscles insert
|
onto the head of the humerus
|
|
|
The humeral head sits in the
|
Glenoid fossa
|
|
|
The name supraspinatus means
|
above the spine of the scapula
|
|
|
The origin of the supraspinatus is the
|
supraspinatus fossa
|
|
|
Supraspinatus inserts
|
superiorly at the top of the greater tuberosity
|
|
|
Suprapinatus is responsible for
|
initiation of abduction of humerus
|
|
|
Infraspinatus sits
|
below the spine of the scapula
|
|
|
The meaning of infraspinatus is
|
inferior to the scapula
|
|
|
The origin of the infraspinatus is the
|
infraspinatus fossa
|
|
|
Infraspinatus attaches
|
slightly inferiorly and posteriorly on the greater tuberosity of the humerus
|
|
|
Infraspinatus action is to
|
laterally (externally) rotate humerus
|
|
|
Infraspinatus inserts on the
|
posterior facet of the greater tuberosity (slightly inferiorly and posteriorly to the insertion of the supraspinatus)
|
|
|
Teres minor originates
|
on the middle half of the lateral border of the scapula
|
|
|
Teres minor inserts on the
|
inferior facet of the greater tuberosity of the humerus (inferiorly to infraspinatus insertion)
|
|
|
Teres minor action
|
laterally (externally) rotates humerus (along with infraspinatus)
|
|
|
Subscapularus means
|
beneath the scapula
|
|
|
Subscapularus originates on the
|
subscapularus fossa
|
|
|
Subscapularus inserts on the
|
lesser tuberosity of the humerus
|
|
|
Subscapularus action
|
medially (internally) rotates arm
|
|
|
Shoulder inpingement
|
When the supraspinatus tendon that runs through the subacromial space is inpinged between the humeral head and the acromion
|
|
|
The most common causes of shoulder inpingement are
|
Bony spurs growing into the subacromial space
Calcium deposits that build up with in the tendon Poor shoulder blade posture and muscle control |
