1. An abutment system for operatively coupling an implant stem to an exo-prosthesis, the implant stem configured for positioning within a prepared site of a selected bone and surrounding soft tissue of a subject, the abutment system having a common longitudinal axis, the abutment system comprising:
a base element having a flange and an elongate shaft, the flange having a first surface, an opposed second surface, and an outer edge extending between the first and second surfaces, the first surface of the flange defining a proximal end of the base element, the proximal end of the base element configured for operative coupling to the implant stem, the elongate shaft extending from a central portion of the flange away from the proximal end of the base element relative to the common longitudinal axis of the abutment system; a plurality of interlocking sleeve elements, each sleeve element of the plurality of sleeve elements defining a central bore configured for receipt of the elongate shaft of the base element, the plurality of sleeve elements comprising a proximal sleeve element and a distal sleeve element, the proximal sleeve element of the plurality of sleeve elements being configured for engagement with the flange of the base element, each sleeve element of the plurality of sleeve elements configured for selective, removable engagement with adjacent sleeve elements of the plurality of sleeve elements; and an end cap configured for engagement with the distal sleeve element of the plurality of sleeve elements, the end cap having a proximal portion and a distal portion, the proximal and distal portions of the end cap having respective outer surfaces, the distal portion of the end cap defining a distal end of the end cap, the distal end of the end cap being configured for engagement with the exo-prosthesis. |
