Anatomy of the Shoulder - Ligaments and Muscules -
....ANSWER ....✔✔ ligaments: glenohumeral capsule,
AC, SC, coracoacromial, coracoclavicular (conoid-
trapezoid), costoclavicular
labrum: cartilage ring that provides static support for
glenohumeral joint
muscles: *rotator cuff - 4 muscles with common tendon
under coracoacromial arch (SITS muscles)
supraspinatus - abd
infraspinatus - ER external rotator
teres minor - ER
subscapularis - IR internal rotator
~ trapezius - stabilizes scapular
~ latissimus dorsi - arm ext
~ pectoralis major - add, IR, horizontal flex
~ serratus anterior - stabilizes and up rotates scapula
~ deltoid - 3 portions (anterior flex, posterior ext,
middle abd)
~ biceps - shoulder flex 2 heads
~ triceps - shoulder extend 3 heads
~ pectoralis minor - stabilizes scapula
~ coracobrachilalis - add

SC Joint Sprain - ....ANSWER ....✔✔ eti: fall on
lateral shoulder, elbow, or outstretched/abducted arm,
direct blow
S&S: look at force, deformity, swelling and pain on joint,
spring test (push on middle of clavicle), pain with abd
before 90 degrees, point tender
tx: rest, MEDS, sling, no EMS too close to the heart
