Abstract
A stemmed implant system can include a stem component and an accessory component. The stemmed component can include 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. The accessory component can define an outer coupling surface adapted to engage the inner coupling surface of the mounting boss of the stem component to secure the accessory component to the stem component.

A stemmed implant system, comprising:
- a stem component including:
- a first portion adapted to be anchored within a medullary canal of a bone;
- a second portion including a mounting boss defining an inner coupling surface;
- and
- an accessory component defining an outer coupling surface, the outer coupling surface adapted to engage the inner coupling surface of the mounting boss to secure the accessory component to the stem component.
A stemmed implant system, comprising:
- a stem component including:
- a first portion adapted to be anchored within a medullary canal of a bone;
- a second portion including a mounting boss defining an inner coupling surface;
- 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;
- and
- a lateral portion adapted to engage the bone and fill an anatomical void within a patient.
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;
- 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.
