Symptoms.—Inability forcibly to extend the forearm, pain atthe seat of fracture, and deformity, provided the fragment isseparated from the shaft of the ulna. A depression marks theseparation. Very great separation of the fragment is not oftenpresent. The interval between the fragments depends upon threeconditions : The extent of the facial laceration—if the lacerationis moderate in extent, the interval between the fragments will be FRACTURES OF THE OLECRANON 2 I I slight; if the laceration is extensive, the interval between thefragments may be great ; the position of the arm, whether flexed.
