Abstract
A prosthesis for the radius bone in the arm of a patient includes a head shaped for engagement with the capitellum of a humerus bone and the radial notch of the ulna. It also has a curved stem that extends from the head and is tapered with a distally decreasing cross section for insertion into the medullary canal of the radius. A system for implanting the prosthesis requires a resection guide for placing the forearm of the patient in a precise anatomical orientation for resection of the radius bone. The resection guide includes a notched alignment rod attached to an adjustable flange and a reference flange for aligning the forearm for a cut of the radius bone perpendicular with the axis of rotation of the radius bone about the ulna, and for measuring the size of the resection and prosthesis.
