摘要：
Anatomically shaped augments that are configured for implantation in a bone and which have one or more reliefs. A distal end of an outer portion of the augment can have a shape that is configured to generally conform to the shape of a metaphyseal-diaphyseal junction of an intramedullary canal of a bone. A proximal end of the outer portion can have a shape that is configured to generally conform to a shape of the metaphyseal region of the intramedullary canal. The reliefs can be configured to reduce a size of the augment and enhance the degree of freedom in the implant positioning and/or sizing of the augment. Further, such reliefs may contour the augment so as to prevent cortical bone contact and/or prevent contact with the implant device that may be associated with misalignment between an intramedullary canal and metaphyseal or diaphyseal regions of the bone.
