Basics Description The olecranon: Is the proximal bony projection of the ulna at the elbow Articulates with the trochlea of the distal humerus to form the ulnohumeral portion of the elbow joint: This articulation is responsible for flexion and extension of the elbow joint. Is the insertion site of the triceps tendon Contraction of […] Basics Description Intra-articular fracture of the distal humerus, which may occur with a supracondylar fracture Biomechanically and anatomically, the distal humerus forms a triangle composed of a medial column and a lateral column that support the articular surface of the trochlea.
