ISA, anterior; 15B, lateral; ISC, posterior; ISD, medial. olecranon process is preserved on the volar surface, and the entire coronoid process and volar surface of the shaft is missing distaily. More bone is preserved on the dorsal surface, which is broken distaily about half way along the M. anconeus insertion. There is some erosion to the volar-most tip of the olecranon process. The M. anconeus insertion area is smooth, and the M. triceps brachii insertion is also non-rugose. A small portion of the proximal end of the M. supinator crest can be seen near the broken volar.
