1. A method for using an elbow prosthesis in a patient, the method comprising:
obtaining the elbow prosthesis comprising:
an ulnar component including a bearing end and an ulnar stem, wherein the ulnar stem is coupled to the bearing end and extends away from the bearing end;a humeral component including a holder end and a humeral stem, wherein the humeral stem extends away from the holder end; andat least one bearing liner coupled to the holder end;wherein the bearing end is configured to be coupled within the holder end to articulate against the at least one bearing liner; making an incision in the patient; determining the proper size for the ulnar component and the humeral component; preparing an ulna and a humerus of the patient; securing the humeral component into the humerus of the patient; attaching the ulnar component to the humeral component; securing the ulnar component into the ulna of the patient; and closing the incision in the patient.
