  1. Elbow joint

  2. Elbow joint - Classification • Compound – more than two bones are involved • Type: Synovial • Subtype: Hinge joint • Movements – allows flexion & extension • Uniaxial joint

  3. Elbow Joint Three articulations • Humerus and Ulna • Humerus and radius • Radius and ulna --cubital articulation

  4. Elbow joint – Carrying angle • Angle between the arm and forearm • 163o • To prevent the ulnar border of the forearm from rubbing against the hip • Facilitates carrying of bulky objects

  5. Elbow joint – Carrying angle Cubitusvalgus • Deformity of the elbow in which it deviates away from the midline of the body when extended. • One of the clinical feature of Turner syndrome(45, XO) Cubitusvarus • Deformity of the elbow in which it deviates toward the midline of the body when extended. Cubitus valgus Cubitus varus

  6. Elbow joint - Articular surfaces Olecranon fossa Radailfossa Olecranon process Coronoidfossa capitulum Trochlea Head of radius Radial notch of ulna

  7. ANNULAR LIGAMENT

  8. LIGAMENTS OF ELBOW JOINT

  9. Elbow joint - Ligaments • Capsule • Envelops the joint completely • Thin enough to allow for movements • Strengthened by collateral ligaments • Attached to the margins of articular surfaces • Lined by synovial membrane on the inner aspect

  10. FIBROUS CAPSULE

  11. SYNOVIAL MEMBRANE

  12. Ulnar collateral ligament

  13. Radial collateral ligament

  14. Relations

  15. Movements

  16. Elbow joint – Nerve supply • Musculocutaneous • Radial • Ulnar

  17. Posterior elbow dislocation.

  18. 3 bony point relationship

  19. FRACTURES OF ELBOW • DISTAL HUMERUS: FRACTURES: • SUPRACONDYLAR • DISTAL HUMERUS: FRACTURES: • SUPRACONDYLAR • INTERCONDYLAR • CONDYLAR • EPICONDYLAR • FRACTURES OF PROXIMAL ULNA: • OLECRANON FRACTURE • CORONOID PROCESS FRACTURE • FRACTURES OF RADIUS: • RADIAL HEAD • RADIAL NECK

  20. SUPRACONDYLAR FRACTURE • This is the most common fracture to occur around the elbow in children (60%). • Fragment gets displaced anteriorly • .

  21. The fracture line extends transversely or obliquely through the distal humerus above the condyles.

  22. VOLKMANN’S ISCHAEMIC CONTRACTURE

  23. TENNIS ELBOW

  24. Tennis elbow

  25. Medial epicondylitis GOLFER’S ELBOW • repetitive motions with poor technique, muscular weakness or anatomical weakness • often seen in the acceleration phase of throwing

  26. Student’s elbow

  27. PULLED ELBOW

  28. Pulled elbow
