Anatomy of shoulder joint

1. ANATOMY OF THE SHOULDER JOINT DR.R.CHITRA., MD,DNB PROFESSOR & HOD OF ANATOMY SIDDHARTHA MEDICAL COLLEGE VIJAYAWADA

2. SHOULDER JOINT-multiaxial spheroidal joint

3. Differences between two limb girdles? SHOULDER JOINT

4. SHOULDER JOINT PECTORAL GIRDLE 1)Dermal and endochordal 2)Two principal components, clavicle and scapula remain separate 3)No articulation with the vertebral column 4)No direct  ventral articulation PELVIC GIDLE 1)Entirely endochordal 2)Three components fuse into a single bone 3)Articulates with sacral            vertebrae 4)Direct ventral articulation at pubis

5. SHOULDER JOINT PECTORAL GIRDLE 5)Shallow joint with limb allowing wide range of movement PELVIC GIRDLE 5)Deep joint with limb limiting range of movement

6. SHOULDER GIRDLE JOINTS

7. SHOULDER REGION-JOINTS  

8. SHOULDER -BONES Roughly hemispherical humeral head Shallow scapular glenoid fossa Articular surfaces- really ovoids

9. SHOULDER -BONES Deepened by glenoidal labrum Covered by hyaline articular cartilage

10. SHOULDER JOINT-LIGAMENTS Capsule is so lax that the bones can be distracted for 2 to 3 cm

11. SHOULDER JOINT-ROTATOR CUFF

12. SHOULDER JOINT-LIGAMENTS Capsule has two to three openings: an anterior, below the coracoid process and another between the tubercles-long tendon of biceps and its synovial sheath

13. SHOULDER JOINT-LIGAMENTS Anteriorly: three gleno humeral ligaments-superior, middle and inferior

14. SHOULDER JOINT-TRANSVERSE HUMERAL LIGAMENT

15. SHOULDER JOINT-DELTOID RELATION

16. SHOULDER JOINT-RELATIONS

17. SHOULDER JOINT-BURSAE

18. Anterior and posterior circumflex humeral, suprascapular and circumflex scapular vessels Suprascapular, axillary and the lateral pectoral nerves SHOULDER JOINT-VESSELS AND NERVES
