                • Ulna dislocated relative to humerus
                  • Ulnar dislocation is usually associated with radiocapitellar joint (RCJ) dislocation
                  • Isolated dislocation of ulna is unusual
                • Isolated RCJ dislocation is not true elbow dislocation
                  • Can occur in children
                    • Nursemaid elbow: Subluxation of RCJ
                  • Rare in adults
                    • Often associated with proximal ulnar fracture (Monteggia injury)
