1. E LBOW JOINT AND RADIO - ULNAR JOINTS D R P K S HARMA

2. E LBOW JOINT Two articulations – 1. Humero-ulnar 2. Humero-radial the complexity of elbow joint is increased by its continuity with superior radio ulnar joint. humero-radial + humero-ulnar = cubital articulation + superior radioulnar

3. TYPE OF JOINT - synovial joint - hinge variety - compound - typical

4. A RTICULAR SURFACES Capitulum and trochlea of the lower end of humerus Upper surface of head of radius and trochlear notch of ulna

5. L IGAMENTS

6. RELATIONS

7. B URSAE RELATED TO ELBOW JOINT 1. Subtendinous olecranon bursa 2. Subcutaneous olecranon bursa 3. Bicipitoradial bursa 4. Bursa separating biceps tendon from oblique cord

8. S TABILITY OF ELBOW JOINT 1. Trochlea of humerus fits into trochlear notch of ulna 2. Ulnar collateral ligament 3. Radial collateral ligament

9. B LOOD SUPPLY -brachial artery -radial artery -ulnar artery Anastomosis around elbow joint

10. N ERVE SUPPLY Articular branches from - radial nerve - musculocutaneous nerve - ulnar nerve - median nerve

11. C ARRYING ANGLE

12. APPLIED Posterior dislocation of elbow

13. GOLFER’S ELBOW (Medial epicondylitis)

14. T ENNIS ELBOW ( Lateral epicondylitis)

15. P ULLED ELBOW

16. S TUDENT ’ S ELBOW

17. D ISTENSION ( EFFUSION ) OF ELBOW JOINT

18. Nerve entrapment - median nerve - ulnar nerve -posterior interosseous nerve

19. R ADIO ULNAR JOINTS Superior radioulnar joint Middle (interosseous) radioulnar joint Inferior radioulnar joint

20. A RTICULAR SURFACES Circumference of radial head Fibro-osseous ring made by radial notch of ulna and annular ligaments

22. B LOOD SUPPLY

23. S UPINATION AND PRONATION

24. M USCLES PRODUCING SUPINATION AND PRONATION Supination -supinator biceps brachii brachioradialis Pronation -pronator teres pronator quadratus brachioradialis

25. MULTIPLE C HOICE QUESTIONS 1. Flexors of elbow joint are a)Biceps b) Brachialis c) Brachioradialis d) All of the above

26. 2) Elbow joint is a type of a) Hinge joint b) Pivot joint c) Condylar joint d) Ellipsoid joint

27. 3) Inferior radioulnar joint is a type of a)Hinge joint b)Pivot joint c)Condylar joint d)Ellipsoid joint

28. 4) Olecrenon bursitis is also called as a) Golfer’s elbow b) Student’s elbow c) Tennis elbow d) Pulled elbow elbow

29. 5) The triangular relationship between the olecranon and the epicondyles of humerus is lost in a)Supracondylar fracture of humerus b)Student’s elbow c)Synovitis of elbow d)Posterior dislocation of elbow
