Stemmed modular implant system

A stemmed implant system, comprising:

• a stem component including:
• a first portion adapted to be anchored within a medullary canal of a bone;
• and
• a second portion including a mounting boss defining an inner coupling surface;
• a fastener;
• and
• a plurality of accessory components each uniquely sized and shaped relative to other accessory components of the plurality of accessory components, wherein each accessory component of the plurality of accessory components includes:
• a medial portion defining an outer coupling surface adapted to engage the inner coupling surface of the mounting boss to secure an accessory component to the stem component;
• a lateral portion adapted to engage the bone and fill an anatomical void within a patient;
• wherein the outer coupling surface and the inner coupling surface form a dovetail joint when assembled;
• and
• a coupling bore adapted to receive the fastener, the coupling bore extending through the medial portion and the lateral portion and intersecting the dovetail joint;
• wherein the mounting boss defines part of an outer circumference of the second portion, the second portion defining an upper most surface where the inner coupling surface extends transversely from the upper most surface to an upper portion of the first portion, and wherein the fastener is configured to be inserted through the coupling bore from the lateral portion toward the medial portion.

A method of adapting a stemmed implant system to a patient, the method comprising:

• selecting a stem component adapted to be anchored within a medullary canal of a bone of the patient, the stem component including:
• a first portion adapted to be anchored within the medullary canal of the bone;
• and
• a second portion including a mounting boss defining an inner coupling surface;
• wherein the mounting boss defines part of an outer circumference of the second portion, the second portion defining an upper most surface where the inner coupling surface extends transversely from the upper most surface to an upper portion of the first portion;
• selecting an accessory component from a plurality of accessory components based on a physical characteristic of the bone of the patient;
• and
• securing the accessory component to the stem component, wherein securing the accessory component to the stem component includes slidably engaging an inner coupling surface of the stem component with an outer coupling surface of the accessory component to form a dovetail joint there between and inserting a fastener through a coupling bore of the accessory component that extends through the dovetail joint, the fastener insertable from a lateral portion of the accessory component toward a medial portion of the accessory component.
