Elbow Joint
35
Elbow Joint
  • Articulations of elbow joint are
  • Capitulum (lateral condyle of humerus) with the
    radius
  • Trochlea (medial condyle of humerus) with the ulna

36
Elbow Joint Ligaments
  • Ulnar Collateral Ligament(UCL)
  • Radial Collateral Ligament
  • Annular Ligament stabilizes and encircles the
    head of the radius
