A shoulder prosthesis including a fracture stem has a body having an exterior surface, a shank attached to the body and a head. The body includes a medial fin, an anterior fin and a posterior fin. The medial fin includes a suture hole. The anterior and posterior fins each include a plurality of suture holes. The prosthesis further includes a lateral suture hole intersecting the exterior surface of the body. The lateral suture hole may be formed in a projection on the lateral side of the prosthesis. In an alternative embodiment, a trail prosthesis includes indicia for noting the proper placement of the stem. The prosthesis includes corresponding indicia for replicating the placement of the trial stem.
