  1. Shoulder Conditions Chapter 11

  2. Articulations • Sternoclavicular (SC) • Acromioclavicular (AC) • Coracoclavicular (CC) • Glenohumeral (GH) • Scapulothoracic

  3. Sternoclavicular Joint • Surrounded anteriorly and posteriorly by 4 ligaments • Interclavicular • Costoclavicular • Anterior sternoclavicular • Posterior sternoclavicular • SC enables rotation of the clavicle with respect to the sternum

  4. Acromioclavicular Joint • Acromion process of the scapula with the distal clavicle is the joint • Superior and Inferior acromioclavicular ligaments • Coracoacromial ligament • AC enables limited motion in all three planes of movement

  5. Coracoclavicular Joint • Coracoid process of the scapula and the inferior surface of the clavicle. • Coracoclavicular ligament • Resists upward movement of the clavicle, downward movement of the scapula, and anteroposterior movement of the clavicle or scapula.

  6. Glenohumeral Joint • Articulation between the glenoid fossa of the scapula and the head of the humerus • Superior, middle, and inferior glenohumeral ligaments • Allows just about all ranges of motion in all three planes

  7. Scapulothoracic Joint • Muscles attaching to the scapula from the thoracic trunk area allow the scapula to move • Stabilizes the shoulder- • Permits many movements of the shoulder

  8. Bursae • Subcoracoid • Subscapularis • Subacromial • Cushion the rotator cuff muscles from overlying bone

  9. Flexion Extension Hyperextension Abduction Adduction Horizontal Adduction Horizontal Abduction Medial rotation (internal) Lateral rotation (external) Movements

  10. Shoulder Movements • Scapulohumeral rhythm

  11. Sternoclavicular Joint Sprain

  12. Acromioclavicular Joint Sprain

  13. Glenohumeral Joint Sprain

  14. Glenohumeral Instability

  15. Glenohumeral Dislocations and Subluxations

  16. Glenoid Labrum Tears

  17. Rotator Cuff/Impingement Injuries

  18. Bursitis

  19. Bicipital Tendinitis and Tendon Rupture

  20. Thoracic Outlet Compression Syndroms

  21. Clavicular Fractures • Blow or fall on the point of the shoulder • Figure 8 brace is worn for 4 to 6 weeks • Pain will be persistent on palpation and active movements

  22. Scapular Fractures • Spine of scapula, acromion process, coracoid process, or the glenohumeral joint • Either direct trauma or a forceful contraction of the attaching muscle

  23. Epiphyseal and Avulsion Fractures • Growth plates do not close until 18 to 25 years of age • Excessive movements of these plates can cause fractures

  24. Humeral Fractures • Violent compressive forces from a direct blow • Fracture is commonly found in the surgical neck
