MODULAR HUMERAL PROSTHESIS FOR RECONSTRUCTION OF THE HUMERUS

摘要

The invention is directed to a modular humeral prosthesis (1) for implantation into a humerus of a patient. A removable fracture cap (40) is provided with a shape so as to allow for space between the cap and the glenoid of a patient into whom the prosthesis is to be implanted. A removable humeral head (50) is provided and may be used interchangeably with the fracture cap depending on the condition of the patient's natural humeral head. Caps and heads of differing sizes may be disposed on the proximal humeral component. A modular distal stem extension (20) allows the overall length of the prosthesis to be selectively increased, thereby allowing the prosthesis to be fitted to patients having humeral shafts of differing sizes.
