Elbow Joint Kinesiology
Elbow Joint • Humeroulnar Joint • True hinge joint • Humeroradial Joint • Restricted ball and socket joint
Parts of the Humerus • Trochlea • medial side • spool like process • Capitulum • lateral side • spherical knob • Medial and Lateral Epicondyle
Lateral Epicondyle C. Medial epicondyle E. Capitulum D. Trochlea
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
Proximal and Distal Radioulnar Joints Movement – Pronation and Supination
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.
