  1. ELBOW JOINT AND RADIO-ULNAR JOINTS DR P K SHARMA

  2. ELBOW JOINT Two articulations Humero-ulnar 1. 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 2.

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

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

  5. LIGAMENTS

  6. RELATIONS

  7. BURSAERELATEDTOELBOWJOINT Subtendinous olecranon bursa Subcutaneous olecranon bursa Bicipitoradial bursa Bursa separating biceps tendon from oblique cord 1. 2. 3. 4. https://encrypted-tbn1.gstatic.com/images?q=tbn:ANd9GcTlYizmlnoMSzhy0sL8D2nvRbUIQC7i3g6BO3odwbfgZMZ6n0Lo8g

  8. STABILITYOFELBOWJOINT Trochlea of humerus fits into trochlear notch of ulna Ulnar collateral ligament Radial collateral ligament 1. 2. 3.

  9. BLOODSUPPLY Anastomosis around elbow joint -brachial artery -radial artery -ulnar artery

  10. NERVESUPPLY Articular branches from - radial nerve - musculocutaneous nerve - ulnar nerve - median nerve

  11. CARRYINGANGLE

  12. APPLIED Posterior dislocation of elbow

  13. GOLFERS ELBOW (Medial epicondylitis)

  14. TENNISELBOW (Lateral epicondylitis)

  15. PULLEDELBOW

  16. STUDENTSELBOW

  17. DISTENSION (EFFUSION)OFELBOWJOINT

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

  19. RADIOULNARJOINTS Superior radioulnar joint Middle (interosseous) radioulnar joint Inferior radioulnar joint

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

  21. BLOODSUPPLY

  22. SUPINATIONANDPRONATION

  23. MUSCLESPRODUCINGSUPINATIONAND PRONATION Supination -supinator biceps brachii brachioradialis Pronation -pronator teres pronator quadratus brachioradialis

  24. MULTIPLE CHOICEQUESTIONS Flexors of elbow joint are 1. a)Biceps b) Brachialis c) Brachioradialis d) All of the above

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

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

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

  28. 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

  29. Thank you
