   • 1993, Journal of Vertebrate Paleontology, Volume 13, University of Oklahoma, page 232:

     Suspensory animals have extremely small olecrana, because of a minimal need for forearm extension, which is achieved by gravity.

     The subcutaneous location of the olecranon makes it vulnerable to trauma.⁷ Isolated fractures of the olecranon comprise approximately 10% of fractures about the elbow,^26,38 with an estimated incidence of 1.08 per 10,000 person-years.
