Lecture 10 shoulder rehab

  1. 1. SHOULDER ARTICULATIONS• Sternoclavicular (SC) Joint• Acromioclavicular (AC) Joint – “False Joint” = Arch Ligament Coracoacromial Ligament between Acromion Process & Coraco Process of Scapula• Coracoclavicular Joint• Glenohumaral Joint• Scapulothoracic Joint
  2. 2. SHOULDER ARTICULATIONS• Sternoclavicular (SC) Joint – Articulation of Superior Sternum & Proximal Clavicle – 4 Ligaments • Interclavicular = between the 2 sternoclavicular joints provides minimal support to the joint • Costoclavicular = clavicle to 1st rib • Anterior Sternoclavicular = broad band support anterior capsule • Posterior Sternoclavicular = small + weak support posterior capsule – Fibrocartilage Disc - Prevent medial clavicle displacement Function = Movement of Distal Clavicle Test = Max shoulder Elevation cause close packed SC
  3. 3. SHOULDER ARTICULATIONS• Acromioclavicular (AC) Joint – Articulation of Medial Facet of Scapula’s Acromion Process & Distal Clavicle (allow minimal movement) – 2 Ligaments • Superior acromioclavicular = acromion and clavicle • Inferior acromioclavicular = acromion and clavicle• Arch “Joint” (Acromiocoraco “AC”) of Scapula – Coracoacromial (Arch) Ligament = Buffer between Rotator Cuff muscles and bony acromion process Test = Humerus abduction 90° cause close packed AC
  4. 4. See Type IV to VITearing of Deltoid andAnd Trapezius Fascia
  5. 5. Acromioclavicular Sprain
  6. 6. SHOULDER ARTICULATIONS• Coracoclavicular Joint (Syndesmosis) – Coracoclavicular Ligament = Inferior Clavicle & Anterior-superior Coracoid process of the Scapula Function • Resist independent upward movement of the clavicle • Resist downward movement of the scapula • Resist anterior / posterior movement of scapula and clavicleVery little movement in this joint
  7. 7. SHOULDER ARTICULATIONS• Glenohumaral (GH) Joint – Articulation between • Glenoid Fossa of Scapula • Head of Humerus – Humeral head 3-4x articulation surface than Glenoid = instability – Ligaments • Anterior = Superior, Middle, Inferior glenohumeral lig. • Inferior lig very thick = main stabilizer in abduction • Superior = Coracohumeral lig. (very strong) – Muscles (SITS muscles) joins joint capsule • Tension holds the humerus head into the glenoid fossa (stability) – Test • Close packed position = Abduction & Lateral rotation
  8. 8. Glenohumeral Dislocation
  9. 9. Anterior Glenohumeral DislocationSee Bankart Lesion
  10. 10. Bankart Lesion = Inferior Glenohumeral Ligamentis avulsed from the anterior lip of the labrum
  11. 11. SLAP LesionInjury to the superior labrum beginposteriorly and extend anteriorlydisrupting the long head of the biceps tendonto the superior glenoid tubercle
  12. 12. SHOULDER ARTICULATIONS• Scapulothoracic Joint – Muscles joining scapula to trunk • Levator Scapula • Rhomboids • Serratus Anterior • Pectoralis Minor • Subclavius • Deltoid • Subscapularis • Supraspinatus • Infraspinatus • Teres major • Teres Minor • Coracobrachialis • Short head of the Biceps Brachii • Long head of the Triceps Brachii • Trapezius – Functions • Stability • Movement
  13. 13. SUBACROMIAL BURSITIS
  14. 14. SUBACROMIAL BURSITIS
  15. 15. SUBACROMIAL BURSITIS
