What are the four muscles that make up the rotator cuff?
|
Subscapularis
Supraspinatus Infraspinatus Teres minor |
|
|
Describe the LOCATION, POI, INNERVATION and MOVEMENT of
Supraspinatus |
Location: Above spine of scapula
POI: Greater tubercle of humerus Innervation: Suprascapular nerve (upper trunk of brachial plexus) Movement: Primary abductor of upper limb=to deltoid pre 90 degrees |
|
|
Describe the LOCATION, POI, INNERVATION and MOVEMENT of
Infraspinatus |
Location: Below spine of scapula
POI: Greater tubercle of humerus Innervation: Subscapular nerve from upper trunk of brachial plexus Movement: Lateral rotation of humerus and stabiliser |
|
|
Describe the LOCATION, POI, INNERVATION and MOVEMENT of
Teres Minor |
Location: Lateral border of scapula
POI: Greater tuberosity of humerus Innervation: Pos branch of axillary nerve Movement: Secondarily in lateral rotation (more important in 90 degrees abduction |
|
|
Describe the LOCATION, POI, INNERVATION and MOVEMENT of
Subscapularis |
Location: Anterior scapula
POI: Lesser tubercle Innervation: Upper subscapular nerve Movement: Primary internal rotator of the humerus |
|
|
Discuss the critical stabilisers ofthe cuff and its layers
|
Cuff behaves as a single unit. Supported by the CORACOACROMIAL ligament
Five layers to the joint -Capsular layer -Messy collagen -Organised collagen -Normal tendon -Ligament superficial fibers |
