Abstract
An artificial elbow joint including a humeral component made of metal and an ulnar component made of resins for replacing an elbow joint. The humeral component of this artificial elbow joint is configured by a substantially cylindrical trochlea and a stem extending from the trochlea that is inserted into the humeral; and the ulnar component is configured by a joint surface member which receives the trochlea of humeral component in a rotatable manner and a stem which extends from the joint surface member and is inserted into the ulna. The stem of the humeral component is curved gently downward overall so as to comply with the lordotic shape of the humeral, and the trochlea is turnable about the centerline of the stem.
