  1. Elbow Joint Kinesiology

  2. Elbow Joint • Humeroulnar Joint • True hinge joint • Humeroradial Joint • Restricted ball and socket joint

  3. Parts of the Humerus • Trochlea • medial side • spool like process • Capitulum • lateral side • spherical knob • Medial and Lateral Epicondyle

  4. Lateral Epicondyle C. Medial epicondyle E. Capitulum D. Trochlea

  5. Parts of the Radius • Radial notch • directly beneath the capitulum of the humerus • Unable to abduct and adduct because of the annular ligament that encircles the radial head and binds it to the radial notch of the ulna

  6. Proximal and Distal Radioulnar Joints Movement – Pronation and Supination

  7. ProximalRadioulnar Joint • The two joints of the elbow as well as the proximal radioulnar joint is completely enveloped in a single extensive capsule • The capsule is strengthened by four ligaments • anterior, posterior, radial collateral, and ulnar collateral.

  8. Radial collateral ligament

  9. Movements of the Elbow Flexion and Extension

  10. Muscles of the Elbow and Radioulnar Joints

  11. FLEXORS Biceps brachii Brachialis Brachioradialis Pronatorteres

  12. EXTENSORS Tricpesbrachii Anconeus

  13. SUPINATORS Biceps brachii Supinator

  14. PRONATORS Pronatorteres Pronatorquadratus
