Presentation Transcript

  1. Anatomy of the elbow

  2. Humerus • Capitulum (lateral)  radial head • Trochlea (medial)  trochlear notch of the ulna • Anterior Coronoidfossa  receives coronoid process of ulna during full flexion • Posterior Olecranonfossa  receives olecranon of ulna during extension • Radial fossa  receives edge of head of radius during full flexion

  3. Ulna • Stabilizing bone • Located medially, longer • Articulation between ulna and humerus flexion, extension (with minimal abduction and adduction during pronationsuppination) • Tapers at the end to form the ulnar head and the styloid process • Doesn’t reach and participate in joint action

  4. Radius • Head of the radius and capitulum flexion and extension of the elbow
