SHOULDER INJURIES

Frozen shoulder –

Chronic irritation of the shoulder joint causing

extreme limitation of movement

SHOULDER INJURIES

Rotator Cuff Impingement Syndrome –

Muscles of the cuff, especially supraspinatus, are impinged

between the anterior acromion and the coracoacrominal

ligaments - decreasing space for muscle to pass

SHOULDER INJURIES

Shoulder pointer –

contusion at the distal end of the clavicle

SHOULDER INJURIES

Bursitis –

inflammation of a bursa (common – subacromial

bursa)

SHOULDER INJURIES

Tendonitis OR Muscle Strain– inflammation of

a tendon (RC or biceps tendon)

Fracture (clavicle or humerus)

SHOULDER INJURIES Sprain

Acromioclavicular - fall on tip of shoulder

AC = SHOULDER SEPARATION

Glenohumeral

Sternoclavicular joint – displaces upward &

anteriorly)

WRAPPING

Shoulder spica – prevents excessive abduction

and external rotation from shoulder dislocation

STEPS

Use 6” DoublePositions arm in internal rotation

(back of wrist on hip)

Pulls medial around arm (pull in)

opposite arm
