摘要：
A prosthetic elbow replacement includes a humeral component having a stem dimensionedto fit within a medullary canal of the humerus and having a yoke connected to thestem wherein the yoke terminates in spaced apart arms. A pivot pin is mounted betweenthe arms for rotational movement with respect to the humeral component. The pivotpin has a transverse throughhole. There is an ulnar component having an ulnarstem including a distal end dimensioned to fit within a medullary canal of theulna and an opposite proximal end dimensioned to fit within a first end openingof the throughhole. The ulnar component has a mounting cap dimensioned to fitwithin a second end opening of the throughhole. A fastener connects the ulnarstem and the mounting cap such the proximal end of the ulnar stem is positionedwithin the first end opening of the throughhole and the mounting cap is positionedwithin the second end opening of the throughhole. The pivot pin rotates to allowfor flexion of the prosthetic elbow replacement, and also allows for axial rotationof the ulna component in the humeral component.
