I. Koretsky et al. 2014	Deltoid crest of humerus very short and terminating at less than 1/2 of length of bone; from base of lesser tubercle, along medial surface of bone, passes a crest that is only slightly shorter than deltoid crest; maximal enlargement of deltoid crest in its proximal part; intertubercular groove very shallow and not well defined; both epicondyles well developed and very wide; distal part of each epicondyle flat.
