| 摘要 |
A variable tilt angle shoulder prosthesis includes a variable tilt angle, comprising a head component including a proximal portion configured to interface with a glenoid process and a distal surface including a socket depression defined therein; a humeral shaft; a humeral neck at the end of the shaft including a proximal ball end which is configured to couple with the socket depression of the humeral head as a ball-in socket joint, adjustable, upon coupling with said humeral neck, to a selected tilt angle among a plurality of tilt angles relative to an elongate direction of said shaft to substantially match said prosthesis to a natural tilt angle of a humeral head of a patient.
