Elbow Dislocations: A Review Ranging from Soft Tissue Injuries to Complex Elbow Fracture Dislocations
Figure 2
(a) The combined mechanical function of MUCL, anteromedial facet of the olecranon and radial head in valgus, and external rotational stability are demonstrated. (b) The yellow spot on the anatomical preparation illustrates types I and II coronoid fractures. Type III fractures of the olecranon (green spot) involve the anterior MUCL, which result in sudden angular and translational instability of the elbow between 30° and 60°.
